Project Zomboid News

Hey all, a good mix of things this ‘doid.

Fun gameplay stuff, and a chunk of info we wanted to flag for modder-awareness and the more tech-minded amongst you. (Feel free to skip that bit to get to the more enticing gun stuff from Fenris that’s become its first application.)

Onwards, then.


[h3]HUNKER INNA BUNKER[/h3]
Permanent underground structures are being added to the internal build’s map for testing.

As discussed before some basement locations will be randomised to add surprise flavour to your looting, but there’ll be plenty of ever-present locations that will likely be survivor favourites for taking over and making your own.

Here’s a fun example, which also very clearly demonstrates the effectiveness of B42’s tech upgrade that governs the realistic spread of light. It really is very dark down there, and with that very claustrophobic and scary…

[previewyoutube][/previewyoutube]


Another aspect of the underground structures is sound, and now we’ve got more and more of these in the test build our sound team will be working to cut out wildlife sounds, add muffle, echo, drips and such. Likewise, meanwhile, another focus is adjusting the noise of ‘street level’ activity when you climb higher in buildings.

It’s also worth mentioning that in 42, or at least certainly its unstable release, you will not be able to tunnel or break down the external walls of underground structures. This is something it would be healthy for the engine to be able to do (although we’d never have Minecraft-style insta-tunnels in vanilla, clearly) but is probably a can of worms best opened later down the line.


[h3]CRAFTING[/h3]
In amongst the feverish connecting of code wires from others on the crafting team, Turbo has been working on the new interface that will allow for hand-crafting items on in-game surfaces.

We’ve got something ready to go into the internal build, but in its current WIP form still needs some polish – and probably isn’t quite ready to show off before its rough edges have been smoothed out.

In essence though, this work has been to cater for crafting items that aren’t as straightforward as ripping clothing to make bandages or opening a can of beans (which will always be feasible just in your hands) but don’t necessarily need a specialized workstation either.

Activities like preparing a sandwich or making a nailed baseball bat logically require a handy surface to perform the work. The way it’s being implemented – any logical surface will do (tables, counters etc) but this sort of crafting will no longer be possible while standing in the middle of the street with zombies approaching.

In terms of changes in player habits and behaviour going from 41 to 42, this will probably be the one that’s felt most keenly. There’s a lot of muscle memory we’ll be scrubbing out here, after all. However we are doing our utmost to keep it logical, and to keep it real.

The current challenge has been to devise an interface that accomplishes all the tasks necessary: providing a handy way of browsing or looking up the recipes, allowing for crafting of multiple objects, allowing the use of tools to modify the quality or success chances of the crafting, and giving access to all the functionality provided in the crafting update.

We’re not there yet on this surface level, but functionally on the code level it’s all there and working and ready to be integrated into the game. Next steps will be to make the UI as clean and convenient as can be, improving and iterating as we go, as it’s such a core aspect of 42.

(Just to reiterate, however, simple crafts like ripping bandages and so on will still be craftable in the way they are in 41: right clicking the item and clicking the relevant right click menu option. This is still the most immediate and convenient way for a player to do these split second crafts in the midst of action.)

Meanwhile, of course, the results of all this new crafting continue to get pumped through from the art department, prepped and laid into the code. Here’s a few that popped through recently.




[h3]MULTIPLAYER[/h3]
We haven’t heard from the MP bods in a little while so let’s go over to Andrei for a little while:

“We are very busy on the Multiplayer side of things. When Build 41 MP was first released we had three coders on our team, and now due to the success of 41 we have five.

As many will be aware we have been focused on anti-cheat functionality for the last several months which is now being finalized: preventing cheating with inventory and items by moving their processing from clients to the server.

Clearly simultaneous to this we have also been working on the integration of new 42-specific gameplay – most notably adding support for animals into MP.

We have also been moving the team onto the fixes, feature requests and changes we have heard from the community.

Some highlights of this are as follows, but please note that our list is long and not everything will be mentioned! If you’ve felt it or found it annoying in your MP play then it is probably on our list:

• Privacy and Anti-Cheat work. We are improving our anti-cheat functionality, and adding various new mechanisms.
  
  
• Improving synchronization of characters between clients. We are debugging and fixing issues where zombies appear unexpectedly for the player, or players teleport instead of walking.
  
  
• PVP animations and logging. Current hit reactions in PVP lead to unfair and unfun behaviours, likewise there are issues with disconnecting during PVP. We are planning to fix this and extend PVP logging.
  
  
• Safehouses. As players will be aware, there are various issues related to exploits and safehouse raids that we need to fix. We also have a lot of things in mind for nice-to-have improvements that we hope to share with you in future blogs.

Thanks to Andrei for his thoughts and, again, to underline – this isn’t the only stuff that’s on their ‘to do’ list. It is, however, what’s in their sights over the month ahead.

While we are talking MP, however, it would be remiss to not mention another side project that’s gone into the game recently.

This is disguise option for multiplayer which, if enabled by the server admin, will allow players to disguise their username by wearing a combination of lower and upper face coverings, or indeed full face coverings.

The hope is that these will create some interesting dynamics for RP and PVP servers, and indeed for general banditry purposes.

(Clearly there’s also a few failsafes having to be built into this! Admins will be able to can also disguise themselves too if enabled and will always see right through disguises, there’s an option to disable disguises inside safehouses, and the system can be disabled entirely on servers that don’t want anonymity to be a feature).


[h3]OTHER FUN STUFF[/h3]
Okay, before we get to some of the more in-depth stuff some quickfire smaller nuggets of interesting things that have gone into the game recently.

We are making some character traits have more direct gameplay implications – with a case-in-point being character builds with vision-related issues. Likewise, helmets and headgear that limit what your player can see will get similar, but not identical, effects.

(PLEASE NOTE: effect seen in the following video is WIP. It was an internal video, but is too fun not to share)

[previewyoutube][/previewyoutube]

The Event Zone’s Wild West tourist attraction is now in testing and open for business – now featuring a new game item that is the wooden coffin.

[previewyoutube][/previewyoutube]

Our good friend Ash from TEA has been working with us to integrate Bink into PZ, which is some cool middleware that grown-up games use to play videos, cut-scenes and the like.

We’re primarily getting it integrated for some cosmetic changes you’ll discover when you boot up the game that’ll be seen at a later date, but it also means that we can now show tutorial videos and such in-game.

In future it also makes moving images on TV screens, cinema screens etc. a possibility – although that’ll be a luxury that comes about long after 42 unstable.

[previewyoutube][/previewyoutube]

Finally, in the Fun Stuff section – Fox’s 4K-ification mission continues. In fact, it’s nearly done and higher-resolution UIs for 4K players will shortly become available in the internal test build.

With higher resolutions, meanwhile comes higher resolution screen furniture. So bid a hearty hello to some of your new, newly detailed, moodles. Friendly folk, aren’t they?




[h3]PROF’S PROC-GEN[/h3]
ProfMobius, he of Minecraft heritage who we brought on board towards the end of last year, has been working on the procedurally generated wilderness to exist outside the map borders to allow for a not quite infinite but huge world outside the main map.

Currently he’s working on automatic blending between hand crafted content such as the edge of the map with the generated wilderness biomes, to allow for a smooth and seamless transition between them without visible borders.

This will also be invaluable for modders, as currently it’s a rather difficult task to blend the edges of a modded map with the vanilla map, which often results in an ugly sudden border of trees or vegetation changes as you transition.

The new system will blend in the procedural elements gradually into the vegetation that exists on a modded map, so the border will be less jarring.

He’s also looking into generating roads so they continue from the borders of the main map, which will massively expand the canvas for modders to position their modded maps – what with them now being able to space them out amongst a huge game world instead of overwriting or extending the main map which will vastly reduce the potential for conflicts.



Definitions for biomes, as well as template for road styles will be creatable in lua, allowing for easy modding to provide more diverse and new biomes with different vegetation, different road styles, and ultimately modders will also have access to the building stamping functionality provided by the basement system and could well extend that to place buildings in the world too.

The full wilderness map will have a different set of biomes to choose from, allowing less realistic but more varied biomes to be feasible: travelling an hour down the road to get from a desert to a tundra, for example.

For obvious reason, however, the extension of the main game map borders will be restricted to sensible Kentucky biomes, but may be able to include stuff like farmland as well as forests and plains.

With this system in place, and the huge swaths of wilderness with convenient road networks to utilize, it’s our hope that a heavily map-modded game could have a truly huge gameplay area 100s of times bigger than currently, with potentially miles of wilderness between major locations added by modders


[h3]IMGUI DEBUGGING[/h3]
Okay – this is the technical bit for modders I warned you about. There’s some fun gun-related stuff afterwards if you make it through.

Finally, we expect this to be more of interest to modders than general players, but it will also impact the ease of future development of the game so is good news all around.

For the ease of integration of various aspects of Build 43 we took some time to implement a debug gui library known as imgui into the game which replaces our somewhat time- consuming lua based debug interfaces. We realised that it would likely benefit Build 42 content too, and as such it became part of its glorious whole – and indeed started giving us results the very next day.

Imgui is, essentially, the industry standard for providing powerful easy-to-implement debugging uis into game engines and it’s already paying dividends.

If you are bored at this point it’s fine to skip to the guns.

First of all, before anyone gets excited about this being used for mod UIs for gameplay, we’re strictly only allowing this to be enabled when debug is activated in the game.

This is because the way imgui needs to be rendered is extremely detrimental to our rendering multithreading since it doesn’t support it on opengl, as well as this the entire point of the system is to provide extremely quick to implement debugging UI that favours ease of implementation over performance.

As such we need to put our foot down on restricting the new UI to debugging otherwise we’d quickly see our performance gains eaten up dramatically by modded games. We do plan a big UI overhaul in future but want to use UI middleware suited for actual end user gameplay, with all the performance, swishes, fades, pulses and slickness the UI finally deserved. ImGui is not that.

In debug mode, the game can now run with more a ‘development IDE’ feel, with various inspectors and dockable windows to examine the bowels of the game and the game viewport as a dockable and resizable window. For example you can inspect all the game UI elements active to allow for easier UI work and debugging within the game, and you can inspect variables on a plotted graph to help balance values over time. Otherwise you can inspect in-game textures and other assets, and numerous other helpful things which should really aid in demystifying the game’s innards for our modding community.

[previewyoutube][/previewyoutube]

Modders will be able to dive in and look into the guts of lua and java at runtime to inspect anything they like: navigating through characters, items, or anything else to inspect them.







Imgui also contains a fully functional text editor. We plan for this to be completely integrated for lua editing within the game itself, as well as a more robust debugger to replace the slightly ropey F11 one we currently have, however this is also a challenge due to the way lua executes so will come later.

In the meantime, for a nice Build 43 behind the scenes, here is the in-game AI behaviour editing UI with breakpoints, stepping and watch window:





In terms of more imminent usage for game-improvement, meanwhile, let’s move over to Fenris at the gun range.


[h3]GUN IMPROVEMENTS[/h3]
From the second imgui was made available Fenris, he of ORGM mod vintage, leapt at the opportunity to use its features to do some intensive firearms work: making them more useful at lower skill levels without breaking balance, while also providing for more tweaks for accuracy based on the player’s actions.

Here he is on the firing range, with imgui active.

[previewyoutube][/previewyoutube]

Here, the graph shows a new AimingDelay mechanic (the blue line) first initially dropping after the player starts to stablise their aim, then rising with each shot – then overlaid with the recoil delay and animation states. We see him taking timed shots and waiting briefly so his aim stabilises again. The effect can then be seen across the different skill levels, and how the rate of fire changes.

Fenris’ work on improvement here is extensive, but aspects of his commits to the game these past two weeks have included:

• Rebalance of how hit chances and recoil are calculated, and general RoF with firearms.
• Improved the target highlighting which was previously misleading, with the colour shifting to green shades with lower hit chances than expected. This is now corrected to go green closer to 80%. Previously only aiming & reloading skills, the distance to target and how long ago you stopped moving had an effect on the highlight.
• Now Strength helps with recoil, Dexterous and All-Thumbs impact on shouldering the weapon, and Eagle-Eyed and Shortsighted can change the optimal sight range.
• Rates of Fire have been increased to more realistic expectations, but it now takes a bit of time to stabilize your aim when initially shouldering the weapon or after each shot. This time is reduced by aiming skill and various traits and conditions. Firing as fast as possible is less accurate then taking your time and lining up the shot. The lighting of the target square is also now taken into account.

[h3]FINALLY[/h3]
We saw this pop up on the YouTubes and thought it was a great run-down on what we’ve been working on. Our thanks to CosmiicSteem for the vid!

[previewyoutube][/previewyoutube]

This week’s foggy safehouse from Rick Grimes, though presumably not the real one. A full round-up of everything confirmed for Build 42 can be found here. A changelist of all our pre-release and post-release patches since the 41 beta began can be found here. The Block of Italicised Text would like to direct your attention to the PZ Wiki should you feel like editing or amending something, and the PZ Mailing List that can send you update notifications once builds get released. We also live on Twitter right here! Our Discord is open for chat and hijinks too. Experienced games industry gameplay coder and want to join Team Awesome? Jobs page here.

It’s been a really big week for us, as we merged the second-to-last element of Build 42 into the main codebase across the rest of the team – which is the long awaited tech upgrade which brings a whole host of improvements to the engine.

It’s currently being tested and the feedback has been super positive so far. This said, it’s also brought over lots of small bugs, visual glitches, and issues with new depth map clipping items incorrectly. Nothing over-dramatic, but enough stuff to keep testers and coders alike fully occupied.

This is where a lot of our brains have been at recently, so we thought we’d give you an update on the engine as it now stands while testers run around kicking its tires – alongside some videos they have made along the way.

Likewise, we also have some examples of some of its new capabilities that we will be able to explore in future – perhaps during the Unstable beta, perhaps beyond.

So, a run-down of what this tech upgrade brings into the game:


[h3]OPTIMIZATION[/h3]
We’ve made huge optimizations to the rendering of the map that should have a huge impact for most lower-midrange and upwards systems. We are now easily able to get a solid framerate even on 4K, or on furthest zoom. The difference in performance is honestly surprising, and extremely satisfying.

For full disclosure, however, we’ve discovered that a few of the absolutely lowest end systems capable of running our game are still adversely affected. This is because the solution for such large FPS optimization comes at the expense of GPU memory usage for the caching textures used. Cards with extremely low dedicated GPU memory may run into problems.

We’re investigating and trying to optimize this further to make sure as many systems as possible can benefit, and worst case scenario these optimizations will be disabled on systems where they would do more harm than good.

However, it’s still entirely possible that we’ll be able to resolve this completely and provide a large boost to even the most potato systems. More likely, we’ll provide some kind of automatic detection to provide as large a portion of the optimizations as possible for a GPU’s available memory. This will be our next task post visual-bug clear out.

Generally we estimate that a huge majority of our playerbase will benefit greatly from the optimizations. Since most of the optimization frustrations we hear come from players who feel their machine should be able to run PZ at a solid framerate, we feel this work will ease the vast majority of performance sadness we see in the community.

[h3]VIEW CONE[/h3]
Another improvement born out of necessity is an improved and smoother viewing cone. Due to the optimizations, it was no longer feasible to alter the lighting of tiles frequently enough to allow for the smooth light changes required for our tile based viewing cone.

As such we needed to implement a completely separate and newly-coded viewing cone that didn’t rely on tile lighting – which truth be told we were never a huge fan of anyway.

Now we have a much more accurate, smooth and fancy viewing cone – and now we have extra hands on it internally feedback is being collated so that we can provide plenty of requested options to allow you to tweak it this way and that. (Making it more or less visible probably being the primary one.)

[previewyoutube][/previewyoutube]


[h3]LIGHT PROPAGATION[/h3]
The new lighting system is now in full testing, and seems to be working pretty well so far.

This new propagation system allows for much prettier and more convincing lighting of the world, especially now we have basements which would have been extremely unsatisfying with our existing 41 lighting.

41’s system basically had an ‘ambient light’ level that permeated the entirety of the world depending on the time of the day. Then on top of that indoors would get a reduction in ambient light to make them slightly darker than outside.

The new system propagates light from light sources such as bulbs, or the sun, across tiles to simulate reflective light. It’s not something cutting-edge that you’d expect from the Unreal Engine, or something, but for our purposes it’s extremely effective. It allows for light from a window to creep across the room, allows for rooms with no natural lighting to be in complete darkness even during the day, allows more immersive coloured lighting, and all manner of other things not previously possible in PZ.

Most importantly of all, it fixes the room lighting issues that plague b41 when room layouts are changed with sledgehammers leaving strange lighting artifacts on the floor, since all lighting is calculated purely based on the geometry of the rooms now.

With this will now come gameplay balance – there’s debate on the team as to whether the player character should have a little more clarity in the darkness, some internal spots are a little more inky-blue than black, and new gameplay elements like not being able to read in the dark will need finetuning to the new visual.

Also seen in the following video, for extra immersion, doors are now fully animated – as discussed last time. This makes a huge difference to the feel of interacting with them during gameplay.

[previewyoutube][/previewyoutube]
[previewyoutube][/previewyoutube]


[h3]OVERGROUND UNDERGROUND[/h3]
We’re still in the process of adding basement spots around the map – whether random or permanent. However, as discussed previously, the new upgraded engine allows support for levels from -32 to +32.

This allows for both much more convincingly tall skyscrapers for city locations, as well as for basements and potentially sprawling underground complexes. The mapping and modding is gonna be wild.

Part of this is also strapping in engine capabilities to help us in future – and as such please take the following as an EXAMPLE video of what we can now do in PZ.

Our coders and mappers have enough on their plates at the moment, and as such this is not a confirmed feature for when 42 goes Unstable.

It will, however, be feasible within the engine which is why we’ve chosen to show it.

Essentially, EP has been working on some extra physics engine functionality to allow for the physics to exist on floors other than the ground floor – as well as providing new physics shapes that in future will allow for this. This work was also a necessary foothold for other physics-based features we have brewing for future versions.

[previewyoutube][/previewyoutube]

Please note also, just to quell any mapper fears again, these extensive engine and map data structure changes will not make existing map mods invalid. All maps will need to be reexported in the new versions of the tools when we release them, most likely around the time we put out the Unstable beta, but they won’t need to be redone from scratch.


[h3]MEANWHILE...[/h3]
We’re waiting on a big commit to fill in some of the gaps in the crafting system process itself, so in the mean-time lets focus on some of the fun stuff that’ll be coming out the other end: weapons.

 

Clearly we already have the more ‘normal’ and traditional blacksmithed weapons for B42 already, and likewise the more ancient-styled stone axes and such. With these we’re avoiding anything specific to any period or culture, going for real life examples that were common across history and geography, and that could pass as something reasonably iron age, medieval, or post-apocalypse. We have consulted an expert in these matters regarding the designs and selection, and we’re also providing them with further weapon designs as we make them for feedback.

But, as we stretch out into our apocalypse we also wanted something a little more… apocalypse-y.



As such, currently what’s being wrapped up are post-apocalypse improvised weapons. These include classic examples like the “nail-spiked weapons”, but also weapons that have been constructed with welding and metalshop tools.

With these designs a conscious decision has been made to not think about weapons from other games or zombie media, and instead research was conducted regarding real life improvised /crafted weapons. This included stuff like police collections of seized weapons and trench warfare, with additional inspiration from weapons in Max Mad-style post-apocalypse media.

We also took on something of a procedural approach, where we looked at the weapons and items that existed (or could exist) in the game, and imagined them being combined like Lego bricks to create weapons. Granted in many cases we just re-invented the wheel, but that helped keep things grounded, realistic, and consistent with the rest of the game.



Although we tried to make these weapons realistic and believable, we have allowed for a couple of weapons to be slightly (reasonably) zany. We’re allowed to have a little fun, after all, and all those weapons will also have realistic drawbacks when wielded.

Simultaneous to this, we are also adding some broken versions of existing Zomboid weapons. Some of these broken weapons and their parts will be used in crafting other weapons, but these fragments also exist for gory consequences when weapons break when bashing a zombie with them.

I don’t quite know why we’re using this strange moustachioed gentleman to demonstrate these today, but lets have a proper look at him in any case. Curious chap.



[h3]BACK TO ANIMS-LAND[/h3]
Finally, a big welcome to Nick from our colleagues at TEA Games who has joined us to help us implement something we call PenguinTech – after the time Zac got two million on-screen dancing penguins into a Wii game.

Originally slated for B41 this will, in essence, be a clever way of optimizing our zombie hordes – pooling what states they are in, and then sharing a smaller pool of zombie skeletons for the same anims. With this, fingers crossed, we’ll get better performance when there’s a horde on-screen and in turn we can be less dainty with their application in your survival.

A full round-up of everything confirmed for Build 42 can be found here. A changelist of all our pre-release and post-release patches since the 41 beta began can be found here. The Block of Italicised Text would like to direct your attention to the PZ Wiki should you feel like editing or amending something, and the PZ Mailing List that can send you update notifications once builds get released.

Happy winter religious festival if you celebrate it, or if you have it in a month’s time, or just if you think it’s nice because you get a few days off while your neighbours drown in eggnog!

Here’s the December news round.
 

[h3]CRAFTING TEAM UPDATE[/h3]

With the last Thurzdoid some people arrived at the mistaken impression that in normal b42 play, the iron ore deposits would exist on the map and be the primary source of metal for crafting. While we’re not ruling this out in the long term, and it’ll certainly be the only source of metal to be found within the wilderness map (more on this later), the primary logical source of metal would always initially be found within the now abandoned civilized world itself.
 


For several builds now, players have been able to dismantle various metal furniture and other objects in the world, including wrecked vehicles, to get metal bars, sheets and scrap. This still exists in build 42, and should serve as the primary source of metal–in various sorts and sizes–for crafting.
 


This also includes taking apart railroad tracks, which is fortunate in that you can use a piece of the track to construct a makeshift anvil.

On the subject of “modern metalworking”, here are some new workstations, a standing bandsaw, drill press, and arch furnace.
 
The bandsaw currently can be used to cut metal pieces into smaller metal pieces, which can save you some wear and tear on your hacksaw, and the drill press can be used to put holes into metal, such as fabricating tools such as header tools for making nails or a drawplate for making wire, among other uses. The arc furnace can be used for melting down assorted items to cast various metal ingots and bars. Now this isn’t the extend of the uses of these workstations, or the end of what we’re adding in this vein.
 


Speaking of other workstations, here are some of the new agricultural stations in b42, herb and crop drying racks, stone quern, and mill, as well as some new crops: Barley, Flax, Hemp (industrial), Hops, Rye, Sugar Beets, Sunflowers, and Tobacco. This gives us a great foundation of resources for textiles, cordage, brewing and oils. We have more crops coming, including some winter crops, garden vegetables, hot peppers, and some pretty herbs.



Moving on to things relevant for the wilderness, here is an example of a campsite made using primitive tier resources. It includes a small worksurface boulder and tree stump, which are naturally spawning workstations that can be used for some basic crafts, including some bootstrapping crafts for getting crafting up and started. Here’s also an example of a small cabin that could be built in the wilderness.



Moving on to the blacksmithing and crafted weapon related matters, as some crafted items consist of handles and heads, some that can be sharp,



Appropriate items will track those conditions as such:
 


There are some other new and very interesting statistics that will be associated with tool and weapon parts, but we’ll discuss this later once its implemented. The goal of these will be to provide much more variety to items, and much greater reward from higher skill crafting, and looting of rarer items.



Aside from being used as part of the “guts and bolts” of the crafting system, this also allows for a more interesting procedural weapon upkeep and breakage system.
 
The upkeep stuff is intended to be warm and immersive, but without an excessive amount of micromanagement. With the examples like the hatchet and spear, you can use the classic items like Duct Tape, Wood Glue, or Zip-Ties to repair the handle, or carve a new one and replace it.
 
Sharpness affects weapon damage and criticals. Weapons at 0 sharpness can still be used to kill, but are less effective, will take longer to chop down a door or a tree, and will accumulate damage faster. Sharpness can be restored using a Whetstone, but is temporarily capped by the weapons Head Condition (or general condition for items like knives). Minor head damage can be repaired with a Whetstone, greater damage with a Grindstone, and a broken blade can be used to make a smaller blade or other item.
 
With the procedural damage system, Sharpness, Handle Condition, and Head Condition all are affected by usage and combat, with Sharpness generally draining the fastest, followed by Handle Condition. When Handle or Head Condition hits 0, the fun stuff can happen with Procedural Weapon Breakage. With the Hatchet, when the Handle Condition reaches 0, the handle breaks, and the Head goes flying.
 
With a larger Axe or other weapon, you may end with with a usable crude wooden club in your hands. Spears basically work the same way, but leave you with a broken stick in your hands and can leave the Spear head embedded in a zombie. When Head Condition reaches 0, the Handle still breaks, but a broken Head is left on the ground or in a zombie, which may be salavged to make something new. Broken Handles can generally be carved to make smaller handles or other wooden objects.
 


This procedural weapon crafting and breaking also serves to give us the bits and pieces to make some nice post apocalyptic makeshift weapons.



Speaking of crafted weapons, Spears are being heavily rethought, reworked, and rebalanced. This is a case where the weapon part and breakage stuff really helps to make Spears more cool and spear-like. You will be able to make simple wooden spears from appropriate items, such as Brooms or Hockey Sticks, as well as Long Sticks, and a Wooden Spear can be Fire Hardened for greater durability and a minor boost to performance . Here’s also some crafted blades and the spears and knives made from them:
 


[h3]THE PROFESSOR’S PROC-GEN LABORATORY[/h3]

Last time we introduced you to our latest recruit, former legendary modder and Minecraft dev ProfMobius.
 
We wanted to get him settled into Zomboid in an area he felt comfortable within, and it made sense for him to perform a trick he last played for Mojang. As such, his first port of call is to look into a wilderness procedural generation system.
 
Please note this isn’t full procedural generation and not intended to create random towns and cities, and at least for now, is purely to provide random wilderness. This will serve two important purposes for Build 42.
 
1) It will allow for the current borders of the premade map to cease to have a black impassible border, and will instead allow players to be able to explore outside the confines of the map a very, very large (though probably not infinite) distance.
 
This will allow players to establish themselves a greater distance away from the premade map and will expand the scope of wilderness based gameplay, as well as locations for settlements that can exist considerable distances away from the existing towns within the game.
 
2) The second purpose will be to allow for servers optionally to be able to generate a complete wilderness map with no towns, roads or other signs of civilization.
 
Not only will this be a good testbed for ensuring that none of our primitive and medieval crafting trees rely upon anything a player would need to loot, but will provide a basis for vanilla and especially modded multiplayer servers to focus entirely around crafting and community building, rather than looting and zombies.
 
The random map generation will have large biomes (all will be sensible for a Kentucky climate environment for the vanilla map border generation, but we may be able to be more imaginative and less realistic on the complete random map generation, and discussions are still happening about this) to add variety and things to discover.
 
While we will not be looking to generate fully random maps with buildings, towns, roads etc at this point, it’s important to point out that the random basement system implemented into Build 42 has required the ability for binary exported buildings from our building editor to be able to be ‘injected’ or ‘stamped’ into the game world at run-time, and this functionality will be accessible to modders.
 
We fully expect modders to have all the power they need to be able to expand the wilderness map with random towns and road networks. It may be something we’d consider exploring at some point once the main map is complete, but until then it’s not something we want to distract from the hand-crafted game world. While we believe random maps would be a cool addition for those who have played the game so much the existing map and popular modded maps no longer feel fresh, we would prefer new players always had the traditional handcrafted map in their first throes of survival.
 
Here’s a quick rough cut of something created with the earliest draft of ProfMobius’ world generation tool – hopefully the start of something cool

[h3]MANY YEARS LATER[/h3]
Just to underline our continued dedication to handcrafted mapping, we have a backlog of many and varied Challenge maps and spin-off maps waiting in the wings for main game inclusion. The one now stumbling and blinking into the stark and glaring light of day is Xeonyx’s Many Years Later.

Given the sparsity of ‘normal’ looting spots this is due to be another of our testbeds for our revamped post-apocalyptic crafting, but it’s pretty fun in terms of just how full of despair it feels.

The recent addition of rats and wildlife also really set it off now. Here’s a quick vid from recent explorations:

[h3]CHRISTMAS ANIMALS[/h3]

Finally, Amz, our video producer and the most ‘Christmas tree must be up the day after Halloween’ Christmassy person in any room that’s ever existed has put together this amazing John Lewis’esque video! We all love it and hope you will too!

Enjoy!

Oh, and in weird bug news we had a problem with infinitely spawning chickens. Things swiftly got out of hand.

[h3]Oh the Humanitz![/h3]

We’d like to point people in the direction of a friend of TIS’s new zombie survival game that’s carving out a slightly different area of the zombie survival niche, a bit more actiony and aiming for something in-between State of Decay and Zomboid in the Venn diagram of zombie survival.

If you have place in your heart for another great zombie game, especially one that’s plenty of fun to play in co-op, make sure to check out HumanitZ on Steam!

Yip yip, hello. Let’s dive in.

[h3]SWING BOTH WAYS[/h3]
Another exciting addition to the build 42 tech upgrade branch has just dropped.

The tech upgrade branch is what contains our optimizations, improved view cone, basement/skyscraper technology and now… an immersive improvement that we’ve wanted for a long time, that could potentially lead to many cool additional gameplay opportunities that weren’t possible before.

That’s right, kids, doors have now entered the third dimension.

Where before doors would just flip instantly on the tile the moment they are opened or closed, now they are animated and use the tech branch’s depth buffer.

This is obviously a huge improvement for immersion, but could potentially lead to cool new mechanics in future (note, certainly not b42’s initial release) like opening doors at different speeds, doors being left slightly open, peeking, bashing open, one-way fire doors and such.

While easy to overlook, our doors are pretty much unchanged since the 0.1.5d days yet also one of the most fundamental things about PZ gameplay – so getting some visual niceness, and some future gameplay opportunities, feels like a win.

So let’s have a quick noisy vid in which doors open and slam shut in unison.

[previewyoutube][/previewyoutube]

(In future we clearly also already have the tech to have doors and visibly opening and closing on vehicles too, it’s already in the code and used by many mods, however in the main game it’s always been the plan to couple this to in-car character animations, visible interiors and such.)

 
[h3]CRAFTING STUFF[/h3]
We’re operating in various different areas with crafting, but the one that’s becoming most interesting and fleshed out with recipes and new items is definitely blacksmithing which has come a long way in the last month.

So let’s head over to Blair to have a chat about the ways in which you’ll be getting to grips with the creation of some of these beauties.



“For blacksmithing in build b42 we have the tiers, workstations, and materials worked out; now most of the crafting recipes have been made as well, and it’s a case where content is being added almost daily as the art assets are completed.”

“Most items that one could reasonably expect to be blacksmithed can be blacksmithed, and in most cases the resultant item is a more rugged, crafted version than the default version of the item that you may be used to.”



“In many cases there are multiple tiers of items, requiring better skills, stations and materials to produce, where it serves the game. Weapons are an example of where this extra attention is being put into the system, where there are distinct tiers of the basic types, that differ in both appearance and performance.”


 
“A lot of work still needs to be done with balancing, as well as getting the fun stuff like animations of the character performing the actions, with fire and smoke. Our artists are hard at work making the assets for all the new items needed for this, but otherwise blacksmithing could be considered ‘mostly done’; you could say that all of the design hurdles have been crossed, and we have solved the ‘Riddle of Steel’.”

“One conceit of b42 crafting is that you should be able to start on a theoretical all forest map; this isn’t a concrete thing that we’re testing yet, but we’re providing foundation for it. Steel production from nothing being one of them.”



“Although iron ore outcroppings are more commonplace in games than in real life Kentucky, we have tiles of them, for use for our own forest maps, and maps of modders.“

(ALERT ALERT: we are aware this is quite game-y, and may well refine in future. For now, however, it works for our purposes.)

“Once you have smashed them into iron ore, you can dig a charcoal pit, and build a primitive forge and furnace, and use the charcoal to extract an iron bloom from iron ore.“

“With a stone hammer and some crude wooden tongs (which won’t survive the process) workable iron is beaten out of the iron bloom, and that iron can be used to produce simple iron implements such as tongs, smithing hammers, nails, and basic masonry tools.”



“Eventually you can work your way up to building a proper come kiln, for both making charcoal, and also coke out of the charcoal for steel production, as well as a smelting furnace, and then an intermediary forge and a grindstone. With this you can produce medium-quality iron implements, that benefit from proper hardening and quenching, as well as higher carbon content.”

“From there one would work there way up to a blast furnace, for producing steel, and then, with the steel, cast and harden a proper blacksmithing anvil and make an advanced forge, and eventually a metalworking bench for making high quality, precision tools and items.”



Elsewhere, meanwhile, we have been going through the game and converting existing systems to the new fluid mechanics that come as a part of the crafting system.

A good example of this, as it clearly shows in the end product, are our hair dyes – even if they are relatively cosmetic as far as the game-proper goes.

In the following video, then, you see the dyes being transferred to (and used from) any fluid container – whether bottles, cans or buckets. Here too you can see them being mixed, and the resulting new colour being applied to the character’s hair. (Elements of this still WIP)

[h3]GAS 2 GONE[/h3]
We’ve given you more sandbox power over how much gasoline is stored beneath Knox gas stations, as previous work in the area didn’t go far enough. You’ll have options to select whether gas pumps are infinite, what their minimum and maximum potential amounts of stored gasoline is, and indeed what the chances are of it spawning completely empty (see image below).

We have also made these a little more user-friendly with better right click feedback on power, required containers, admin info on fuel remaining etc. We’ve also added a more visible fuel caps on our car models, and indeed a fuel-side indicator icon on your vehicle’s dashboard.


 
[h3]VOICE SETS[/h3]
After the successful integration of the body noises, “hey!”s and “psst!”s of a real actor and a real actress – we made the call to widen the net a little and get a variety of different people to record specific voice/noise sets for the game.

There will now be four male and four female voices that you can choose at character creation stage, which will also mean that in MP those around you will likely have slightly different puffs, pants and combat exertions.

Likewise having a more particular sound to your voice and character will likely be good for your own personal RP reasons.

(Please note here, again, that exertion noise frequency hasn’t been 100% balanced yet.)

[h3]ANIMALS[/h3]
It’s relatively easy to slot in new animals to RJ’s system, the modding scene will likely be fairly extravagant, so while fixing bugs with our chickens, cows, sheep and pigs – he’s also slipped in some raccoons and wild turkeys to roam alongside the deer.

[h3]4K PZ[/h3]
Fox’s up-rezzing (and slight tidy-up) of all the game’s many windows, icons, menus and general game furniture continues. In fact, we’re now at a point in which many aspects of the game can be played at 4k without the need for squinting and a magnifying glass.

Folk with higher-res screens have long-suffered with Zomboid, so we’re excited to finally put this issue to bed – as can be seen in the following 4K video.

Please note, however, that some windows here still feel a little crowded – we probably need to loosen up the crafting window that could use a bit more padding, the tabs feel a little close together etc.

[previewyoutube][/previewyoutube]

[h3]MAP NICETIES[/h3]
The map expansion, and elevation/lowering, continues apace. Something else we are bringing to your exploration is a little more colour and character to the places you are surviving within – as such there’ll be more variety of things left on whiteboards and chalkboards in schools, universities and laboratories for example.

Meanwhile, there’s clearly elements of signage Americana we can use for our game too. Case in point, being a wide range of different signs outside our churches.



We’ve also got an, as yet unnamed, Wild West tourist attraction going into the game – which could also potentially be a good place to find some of the crafting gear that’ll be new to 42. Maybe a couple of cowboy actor zeds shambling about as well, for good measure.



[h3]DRESS UP BOX[/h3]
We generally don’t populate the map with Mad Max lookin’ zeds, but people certainly seem to like having a little more freedom in terms of the threads you choose to go a hunting and a’ looting in.

As a side project from his crafting duties, then, Blair has worked with animator Martin to improve the clipping issues folk often come up against with certain combinations of clothing. This issue was becoming more and more apparent with the crafted straps and metal shin guards being developed in the blacksmithing aspect of 42, so needed nipping in the bud.

Essentially, now clothing items and body locations can have set definitions – which then instruct the game to use alternate clothing models in particular circumstances. So a different arm guard model, for example, will be automatically used if the character is wearing a bulky jacket. We feel that this will have massive potential for modding.

On top of this we have also made it so accoutrements like limb armour (shin pads, for example) can go on either limb; you can wear just one, or a pair, or a mismatched pair. This said, so it’s not too annoying, they’ll appear as matched pairs in loot or on zeds.

Finally, while not entirely linked to this endeavour but still in the same ballpark, helmets/headgear/masks all now affect your vision cone and your hearing (modestly) which we’ve added as a balancing measure for when crafted helmets are in the game.



Oh, and the above also means we can have (American) Football Shoulder Pads in-game too, so expect some varsity jock zombies wearing those around campus also.

Here’s a somewhat silly, but fun, screenie showing a little bit more of what this system can create – including a bunch of the new items that will be craftable with the new blacksmith/forge systems.



[h3]NEW HIRES / RETURNING FACES[/h3]
We’ve expanded a lot over the past year, and we had called time on anyone else for fear of things running away with themselves.

Clearly Soul Filcher joined recently, and unmentioned in this blog we’ve got Fenris in the guts of our Discord integration, Patrick with his (very encouraging) experimentation with ragdolls, and there’s a hugely experienced guy called Matt who we haven’t announced before who’s putting in foundations for future engine improvements. After all this we mentally shut the door on likely changes and additions, until…

Zac, the coding maestro behind 41’s animation systems, made his return to work after a long period away this month – and is now working the kinks out of issues we’ve had since he was last with us with character rotation and movement.

Here’s a link to show his WIP improvement – though it might not be super-perceptible in vid-form. When this is all sorted the in-game character should feel more responsive, and also give us more flexibility when improving on the general animation suite.

He also brings alongside him a lovely guy from Tea Games called Ash, who’s helping integrate the video play middleware Bink into the game which will (among other things) help us mix some improvements into our title screen, and to provide combat video examples in our tutorial windows and such.


[h3]THE PROF[/h3]
The other guy, meanwhile, who’s burst onto or internal development scene is someone we know as ‘The Prof’.

Thomas ‘ProfMobius’ Guimbretiere comes to us by way of Minecraft, and some players might already be familiar with his mods and work over in block-land. He started modding Minecraft something like 13/14 years ago and co-produced MCP, the predecessor of Forge, before later authoring important mods like Waila, Jabba and Opis.

He was then hired by Mojang themselves for work on Minecraft Java (ooh, Java) and went on to work on oceans, corals, new villager AI, village construction and a full rework of the game’s world generation. All of which is, clearly, hugely relevant to our interests.

Since his Mojang days, he’s been working on the backend of Razzleberries (https://razzleberri.es/) but now he’s in the iron grip of Spiffo. To begin, to we’ll be easing him in on something he’s familiar with that we’ll probably cover next time. There’s plenty of fun stuff planned beyond that too though.


[h3]HAPPY THANKSGIVING[/h3]
For all you Americans, Amz has made you a Thanksgiving vid. It’s got some WIP raccoons in it and everything.

Though, thinking about it, maybe we should have gone with the turkeys. Anyway…
