Project Zomboid News

Hey all, here’s the highlights of the last four weeks of Project Zomboid development – compiled from the Thursday blogs that appear at projectzomboid.com and on the PZ Steam boards.



First off, a general ‘recently implemented animations’ video to whet your appetite along with some new Zach Beever musical goodness that will be coming in build 41.

A key aspect of PZ mapping is zoning – which we primarily use to mark up areas that are (for example) suitable for foraging and car spawns. Now however, with different clothing for zombies, we can flag which parts of the PZ map can spawn which particular zombie – or which group of particular zombies.

This, then, is how we can spawn only guards and orange jumpsuit-wearing prisoners in Rosewood prison.



Likewise, RJ has created a ‘wedding’ spawn zone over one of the churches on the map – which ensures that all zombies inside it, and outside for the selected area, have a very high chance of dressing in smart clothing, with a guaranteed bride, groom and church minister amongst them.

This system will allow us to have many and varied different pockets of particular zeds – police in police stations, lumberjacks at McCoy logging, military in military areas etc. Likewise, we will be examining the best methods to make sure that zeds in bathrobes or not wearing clothes are only found in homes and home bathrooms in particular.

(It should be noted that aspects of this will also involve a very slight rewrite of PZ lore in terms of the outbreak, but we had intended to return to the radio/TV broadcasts soon in any case).



We’ve been waiting for some important/complex work on rotational anim movements from TEA for a fair amount of the past few weeks – but there’s still been plenty of other areas for us to work in this time.
A few examples of this includes knife attack animations, and tying survivors and zeds getting bloodied by attacks in general in-game.

This has also involved us adding some additional combat skills, and in the process removing the skill point system. From Build 41 onwards skills will automatically level up when you gain the XP requirements, as we felt the manual skill point system never worked particularly well and would do so even less with many more skills.





RJ also adds a note on how running through crowds of zeds will now be a little more fraught with danger.
“One thing that’s new and that people might be interested to see in action, is an effort to make sure players can’t dash through hordes without getting slowed down.”

“As seen in the video below, we’ve now added bumping against zeds. Colliding with one or two while you’re running isn’t dangerous, you’ll just get slowed down, but try running through a horde and you’ll stumble and fall – leaving you temporarily exposed to the encroaching zeds. We might add in a few more different sorts of animations for nudges/pushes, but right now it looks like this:”

Next up, the issue of character and zed model visual fidelity.

An area that was proving strange in terms of 41 development was that somewhere along the way some of the visual fidelity of characters had been lost – and simultaneously, somehow, models looked far more buff/hunky than intended. Feet, also, seemed a little on the large side. After a bit of a dig, we finally located a bug in the exported model data that explained it.

Due to this bug, the lighting of the characters was broken, which resulted in very washed out characters with little lighting shading – which in turn removed definition that made muscles look bulkier. This has now been fixed and, after re-exporting all the clothing, has allowed us to achieve much better character model rendering and lighting than we’ve shown off previously during this recent leg of anim development.

As ever, please keep in mind that we’ll continue to balance/tweak to make sure characters fit their surrounds as well as possible – as well as adjust the models themselves seeing as you can now see individual facial features much more clearly. These caveats notwithstanding, however, we’re pretty happy how they’re looking.



During this process we also focused on another prominent issue: that the character pixel resolution when zoomed in was extremely blocky and lacking in detail. Due to the ways that our initial zoom system handled things, characters were too harshly pixellated. This caused them to be extremely jaggied compared to what it was in the old days, when we were rendering characters to an off-screen sprite before placing them into the world.

So over the past few weeks we’ve been doing some significant work on changing how the game handles the zoom, which in addition to fixing this issue should ultimately lead to slightly more optimized rendering of the game – as well as providing the character models much more detail to play with.



The branch with this system on it isn’t complete – navigating indoors presents issues, mouse input hit-testing isn’t fixed up yet, and we’re having issues with seams between tiles when zoomed out – so it’s not quite ready for integration into the main test build. Here’s a quick video of us running aimlessly around zombies under lights to show it off though.

(Along with some new Zach Beever musical accompaniments!)

Zac and Mark from TEA have continued their work on the tech, ironing out the last few issues with the animation blending, as well as providing some extra cool tools to help us implement and debug the animations (as well as the modders once it releases!)

• Zac has been doing a whole bunch of optimization work, with fun example vids of his wares seen here with his zombie spawning, and here with multi-threaded rendering.
  
• RJ has implemented his previous work on looting improvements – giving us more control over general clutter, and more realistically placed items in houses.
  
• Mash has begun creating icons for new clothing and weapons, Will had begun setting naming conventions for them.
  
• Connall and Turbo have continued to implement new timed actions.
  
• Yuri has finished adapting his water/puddles into Zac’s revamped shader system, and is now experimenting with a particle system that will provide the bedrock for his fire improvements.
  
• The other Zac meanwhile, Young Zach, continues to deliver the new South-tinged PZ score that can be heard at playing over the initial video in this blog.
  
• Xeonyx is chasing/fixing map bugs in his now complete Kingsmouth Island challenge map.  
  

Hey all, here’s a round-up of recent Zomboid dev. To start with a quick video compilation of stuff the team has been wiring up into our friends at TEA’s animation systems.

https://youtu.be/HhM6eIrxNYA

Please note that there are still numerous bugs and issues as long as all our combined arms, and it’s hard to get a sustained video without issues and glitches popping up, so this vid is fairly carefully curated – but it does give you an idea of the where we are. (Likewise, if you see something that looks wrong or glitchy, or think ‘hmm, there should be more variation anims in that…’, then we’re probably already on it).


Essentially, TIS coders are currently implementing the game code-side, tying in the new animation system to all the game systems. RJ, for example, has been handling the combat system, tying up all the weapon swing, zombie reactions and various other related anims, and the system is getting close to the quality of the earlier videos of animations you’ve seen, though now tied 100% into the PZ combat, character and simulation systems.

Connall and Turbo, meanwhile, have been concentrating on non-combat related animations, such as reading, chopping wood, painting, eating, crafting, and the countless other in-game actions characters can do in-game that were previously performed like a stock-still robot with a progress bar.

EP has been doing his usual precision striking all across the code base, wiring up the character creation system, connecting model clothing to inventory items in the world, and fixing issues and integrating the codebase across the board.

In the mean-time TEA are optimizing and improving the AnimZed toolset with our requests the more we use it, and alongside general animation requests and polish Martin is experimenting with the gore potential of the system with visible guts hanging out of the front of zombies and such.

Here’s another vid from Zac from a two weeks ago: a walk through downtown West Point to test some of the latest optimization work, and the improved shaders that remove a lot of the bleached-out-ness from proceedings. At the moment Zac is also, still, looking into some further threading optimization as, bizarrely, better machines were having some stutters

https://youtu.be/Ge3IZlzOzRE

This past week we’ve also reimplemented zombies that spawn covered in blood (when the Version 41 is complete blood will gradually appear on most zeds during combat, however), which can be seen below – alongside a few items ticked off the list from Connall and Turbo’s vast timed action spreadsheet.









We’re also in the process of working out exactly which animations will be included in the first release, and what won’t – the Cover System; i.e. ducking behind walls and wall-hugging for example, is a confirmed ‘not 41’ at this point as we want to get the fundamentals right first. (edited)



ChrisW is back with us currently, and working on better internal visuals for buildings. Screenshots probably speak louder than words in this instance, so here we go:







Yuri has been putting the finishing touches on the puddle system, as well as tying it into the 40’s climate stuff, and we’re super happy with how he’s been able to add that visual spark to the water effects in the game. Here’s a video of where he’s up to:

https://www.youtube.com/watch?v=6w5PAhh-pGE

And here also is an earlier video, showing the more WIP shader effects appearing on roads.

https://www.youtube.com/watch?v=_n_HxL0eh1E

Our next plans for Yuri’s visual effects overhaul couldn’t be more opposite, as we want him to give some visual love and attention to fire: one of our most ancient and jankiest looking systems. We’re excited to see what he does with it, and at the same time as a visual boost, we’re planning on rebalancing the way fire works to make it behave more sensibly and better simulate its spread over different materials and tiles.



Stas from General Arcade has been going great guns with our public controller beta, and we’re now well into the bug fixing and polish stage. If you want to check out the latest version, number 14, details on how to join can be found here.



While the rest of the team works on Build 41, we currently have three people on map content. Mash is developing our take on Louisville, while RingoD is providing her with variations on our current housing models so that its suburbs don’t feel too cookie-cutter.
Here’s a rare glimpse of a WIP urban location that’s been prised from Mash’s iron grip, shown with the understanding that the release will be a fair few builds into the future.



Seeing as the main map expansion is still so far away, however, we now also have the New Denver creator Xeonyx working on new locations that will come as a part of new challenges in the main game. Here, for example, is the main resort building on the fictional paradise island of Kingsmouth.

Hey all, quick run around the houses talking about who’s on what this week.

In anims-land for Build 41 Zac’s been looking at optimization, which we’ll be coming back to pretty routinely from this point – as we want to make sure everything is nice and smooth. Here he’s sorted out some locks in the render thread, and from the Before and After you can see a marked improvement in quality.

https://www.youtube.com/watch?v=1fZ03VjhJr0

He’s also working on getting the shiny helmet / coats / leggings shader effect going for different clothing items, and also investigating with Mark as to why over the course of development with the animations system we’ve lost some of the earthy colours and harsher lighting that tended towards a slight over-saturation and bleached effect that doesn’t quite make the new character models fit the scene.



Animator Martin, meanwhile, is looking at all the different locations we’ve got on the map (and those still to come) and creating new outfits to discover in their cupboards and lockers – and likewise to find the local zeds dressed up in.





Xeonyx, the creator of the much-loved New Denver / Slocan Lake map, is now working on Challenge Maps for the main game. These, including the Film Studio map we’ve discussed previously, will most likely be a part of Build 41. His current mission is a fictional map called Kingsmouth – a ‘paradise island’ vacation resort in the Caribbean. The map will feature vast hotels, seaside locales, a military installation and much more – but we’ll go quiet on it for now while Jamie gets on with his work. Here’s a quick screen from the map editor though.



Chris W continues his work on improving visuals within buildings – aiming for more Sims-style cutaways and the removal of the circle stencil we currently use. Here’s a quick before and after of the start of this work – the second image showing walls in the foreground cutting away to skirting height – with smooth transitions curving up to full height.

NOTE: Very much WIP and not a finished system, of course. The other room currently isn't cut but will be in the final version. This is just a sneak peak for the WIP system and showing off how the rounded corners look; the goal for the final version is improving vision, not limiting it.



 

• Yuri is working on improvements to the way we render the ground surfaces, especially road textures that have been rained on, to complement his recent improvements to how water appears in-game. (This said, right now, he’s shackling a hilarious car physics demon that’s sprung up on an internal server.) 
• Stas just released an updated Controller Test beta for those helping out with our gamepad improvement scheme. If you are interested in getting a free PZ code for your troubles, then join our band of testers. 
• While BitbaboonMark does some TEA-side code repository movements and merging: RJ is doing some improvements to food crafting and prepping a (non-anims) forum test for his new loot table improvements, EP is doing some very exciting experimental work with a new player map system and Turbo is plotting his next move after the successful integration of his weather/shaders in Build 40. (Most likely picking up on his work on in-game devices, or maybe those seasonal sound effects we discussed before).

We’d like to direct your attention to the new Hashima Island map by Woldren, a map based on an IRL location you might recognise as the place where James Bond shot a woman who had whiskey on her head in Skyfall. It’s pretty damn cool.



We’d also like to direct your attention to the Redboid server, which had a season refresh/reboot/restart yesterday and is a grand place to start your PZ MP adventures if you haven’t done so yet.

If you run a PZ server and would like a shout-out in a future blog, then please get in touch. And while you’re at it -please use these values in Bitbaboon Steve’s recent networking optimization options, as they certainly seem to be helping those currently using ’em.

This week’s infested neighborhood from Dark Oracle. A general list of stuff added to PZ, and vids of features being worked on, is kept here –so you don’t have to plough through endless dev blogs for info. 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 MailingList that can send blogs like this and patch notes direct to your mailbox. We also live on Twitter right here! Our Discord is open for chat and hijinks too.

Howdy almost-yuletide survivor.


Today we released our final (sort of, read below for more on that) patch for Build 40. Full patchnotes can be found here, but this covers stuff like:

• Improved darker nights, and less washed out night-time interiors. Car headlights and flashlights will be more of a necessity now. Sandbox settings also updated, so you can adapt it to a brightness you desire.
• Improved appearance of weather effects when in a building.
• Moon calculations re-added to game to govern night brightness.
• Extended disassemble ability to many more items,including: fridges, ovens, more chairs, washing machines, lockers, fitness equipment, metal barrels and some missing shelves.
• Some balanced player actions related to injuries, sleeping, window-breaking and bandages in a saucepan.
• Fixed whisper problems in the new chatbox, stair teleports, rain rather than snow in Winter is Coming, community translation font issues, plumbed sinks not working in MP and various other issues.

While the rest of the team move into the animations build and version 41, we’re leaving optimization specialist Bitbaboon Steve investigating what easy-win MP networking improvements we could potentially still patch into 40.

The first of his discoveries, the removal large number of empty and unnecessary data packets being sent over the server, has been released in 40.40 and should be a mild salve for current lag issues but his investigations also came up with an idea we thought it’d be wise to test out with a forthcoming IWBUMS beta and Community Megatest.

Essentially, Steve has been working on some server configurable optimizations for zombies in multiplayer. Since vehicles, performance in multiplayer servers has seen added strain (particularly in handling zombie hordes) and we’re hoping this might improve matters.

In essence, we’re about to release a test version in which there are several configurable options to allow server owners to fine-tune how much zombie data is sent to their players.

There will now be two ‘player client zombie awareness’ circles: the first a smaller radius that defines at what tile-range zombie positions are sent to clients with a high precision in every frame, and then a second larger radius in which the zombie location information can be sent to clients less frequently. Server owners will also be able to play with how much time there is between the low frequency updates.

On low population co-op servers these values can be set pretty liberally, so the players are getting all zombies in the visible area smoothly. But on high population servers that experience lag issues, server operators can sacrifice the smoothness of zombie movement in the distance (or even cap zombie visibility completely over a certain distance) in order to VASTLY reduce the amount of internet traffic they produce when lots of players are involved.

We think this will sharply decrease the amount of work the server needs to do and should lead to a much better player experience with a little bit of visual compromise toward the edge of the screen. Distant zombies might pause a bit or appear to teleport slightly between updates, but these movements are also something we’d hope to blend better (and make far less noticeable) with the added functionalities of the animations build. Server operators can decide on their own level of compromise too.

This work is pretty much done, and as such we will add it into the IWBUMS beta as soon as it’s clear there’s nothing from 40.40 that needs hot-fixing. Please keep your eyes on the forum if you want to participate in a special Yuletide Megatest.



This week in TEA-land Grant has improved things dev/modder-side with live texture reload, through upgrading the Filewatcher mechanism. It now watches the media folder instead of polling individual files, and is much more efficient. Upon a texture filechange, the game now reloads it live and in-place. This should make iteration times on textures much easier and faster.

Zac, meanwhile, has fixed up AnimZed for Animator Martin to the extent that he can now get a lot more variation on different individual outfits. Take these cops for example:



Martin has also been creating a better range of skin tones for player characters, to allow for better customisation should people desire it.

• Stas has just updated the Gamepad Test beta with a lot of fixes, for our lovely select bunch of gamepad testers. If you fancy helping out with this part of PZ work, and earn yourself a free code, then enquire within.
• RJ has been tinkering with in-game loot, and has occasionally been popping into the PZ Discord to look for willing testers. The overall plan is to have more information in the game code in terms of what’s a desirable item, and what’s junk – so we can then fill containers with a lot more realistic junk items even on higher difficulty levels. He’s also experimenting with having more specific containers in homes for more specific items (all the cutlery in one drawer, male clothes in one wardrobe, female in another etc) but the jury is currently out on whether it actually detracts from the looting gameplay.
• ChrisW’s work on in-building Sims-style cutaways and the abolition of the dithered circle view stencil continues. As seen here both with, and without.
