Hard Chip News

Greetings, Hard Chip players!

Let's review the changes made from versions 0.0.6.12 to 0.0.6.17. This update is another round filled with enhancements, new features, and fixes to improve your experience. Here's a detailed overview of what's included in this update.



[h2]1. UPDATED Lab area and Fab control area[/h2]
The mini FPS part of the game has been reworked to include more terminals and machines to repair, which will give players more frequent rewards. The previous lone chip map was the entire Adder in one go. Now, it is split into three parts: bypass chip, Inverter chip, and Adder chip.




Not only that, but we've also made significant performance improvements to ensure a smoother and more enjoyable gaming experience.

Changelog:

• NEW Fab area;
  
• NEW Fab area is used for Adder now;
  
• NEW Visual cue model when a chip is fabricated;
  
• NEW Starting area with two machines to repair, Material Bank 1 and Material Bank 2;
  
• NEW Bypass Chip Map, Inverter Chip Map, (and then Adder Chip Map);
  
• NEW Adder chip map shortened for material bank2 and material bank 2 repair;
  
• PERF Improved loading time for the fps part;
  
• PERF Prepping off screen loading logic;
  
• MI Improved hitboxes for the Fab area, fixed pipes' textures with wrong UV;
  
• MI Generator wiggles;
  
• MI Terlinals flickering is back;
  
• MI show only one "replace" action when a chip is in hand;
  
• SX Story mode scripts are more rewarding with smaller steps;
  
• SX Remove misleading instruction on build-up;
  
• SX 8Bit in terminal logs as it's now the required part;
  
• MI Updated starting area, dark portion;
  
• MI Terminals of fixed machines are locked now (avoid players guessing if it's still useful);
  
• FIX Inputs as terminals hack;
  
• FIX Stuck on mbank1 on reboot;
  
• FIX Falling through the doorstep;
  
• FIX partial crash in UI screen in world;
  
• FIX start fabrication process twice;
  
• FIX reboot labcontrol twice;
  
• FIX typo in Crossing state;
  

[h2]2. NEW Saving best player solutions and Comparer mode[/h2]
One of the primary loops of HC is getting the perfect part with the help of 4 metrics that help the player gauge their progress. But for visual people, seeing the best solution they have made against their latest attempts is even more helpful!

[previewyoutube][/previewyoutube]
Every time a metric is beaten by the player's solution (block count, volume, ticks, or mos count), a "ghost" is saved. Then, you can load those ghosts to compare your current attempt with your best ones!

And for good measure, 2 more save slots per level were added. You can now have 5 variants for each level!

Changelog:

• NEW Show best ghost from Perf report window;
  
• NEW 4 best ghosts are saved when one of the 4 metrics is beaten;
  
• NEW Comparer mode with transparency slider;
  
• NEW ALU Chip map (placeholder as of now, WIP);
  
• NEW 2 more save slots;
  
• UX Clicking graph to compare with best solutions;
  
• MI Tutorial doesn't save bests;
  
• FIX Z-fighting with ghost and everything else;
  

[h2]3. NEW Negative number representation with associated challenges and chip map.[/h2]
A chip map is a set of challenges to build a chip that can be used to repair a machine after replacing that chip and rebooting.
So far, only a positive number adder could be done. And you know what the next logical step is!

Challenges based on negative numbers!





This part is very early still, but it offers great potential for upcoming levels and new sorts of chips! This one is an very rudimentary revised adder chips that can now perform substraction!

Changelog:

• NEW Negative number representation with 2s complement, usable in some challenges;
  
• NEW Challenge type: play with inputs to finish;
  
• NEW 8bit signed challenge;
  
• NEW 8bit value inverter challenge;
  
• NEW 8bit Adder Substracter challenge;
  
• NEW Adding schematics for AdderSubstracter, ValueInverter;
  
• NEW 16bit Adder bonus;
  

[h2]4. UPDATED Movable Input/Outputs[/h2]
Movable outputs were already in the last update for the demo. Now all inputs/outputs are movable and already benefited from a week of bug fixing.

[previewyoutube][/previewyoutube]

Changelog:

• NEW Movable inputs; Saved in file; Clipboard exportable; Sticked to the left edge;
  
• NEW Dedicated Input/Output overlay (stable between steps), cleaned previous input readout;
  
• UX Show check/cross on expected numeric output (not only bit value);
  
• UX InOutput position at y=2;
  
• UX Indicating +- hint in Mode Bar when moving outputs;

Thank you for playing Hard Chip, and stay tuned for more updates and new features!

Greetings, Hard Chip players!



Let's review the changes made from versions 0.0.6.1 to 0.0.6.11. It's been four weeks since the last update, so this one is filled with enhancements, new features, and fixes to improve your experience. Here's a detailed overview of what's included in this update.


[h2]1. NEW Movable Outputs[/h2]
One of the most requested features, Movable Outputs, has been rolled out. You can now move outputs, which makes organizing your layouts much more intuitive. This feature supports both 1-bit and n-bit outputs.

Additionally, the spacing between inputs can now be adjusted on the fly using the + and - keys while picking positions, giving you more control over your circuit designs.



Changelog:

• NEW Movable outputs (with a picker)
  
• NEW Select Output mode with dedicated cursor;
  
• NEW Movable Output supports 1bit and n-bit outputs;
  
• NEW Change spacing between input when picking position with +- keys;
  
• NEW Movable outputs don't reset their screen position when changing the validation step;
  
• MI Ensure output picks hint and stays to the right edge of the die;
  
• MI Exportable output picks
  
• MI Saving output picked positions in savefile;
  
• MI Tutorial challenges with no movable inputs;
  
• UX Softescape from output selection;
  

[h2]2. UPDATED Graphical Enhancements and Multimonitor Support[/h2]
Visuals play a significant role in the overall experience; we've taken this to heart with several key improvements. The introduction of a Cubic Renderer for performance settings. The new Resolution Scale setting allows you to get the most out of your graphics card for an unparalleled level of detail. Or, if you don't have a graphic card to use, you could turn the dial down to 40% to get those sweet FPS back!

The new cute environment


Super scale 100% compared to 200%


Voxel edge artifact removed (100% render scale)


Cubic fast renderer


In addition, Multiscreen Support has been implemented, allowing you to start HC on any screen. Previously, you were stuck to the primary monitor. Note that HC is DPI agnostic across screens.



Changelog:

• NEW Cubic/Raymarching renderer settings for performance;
  
• NEW Resolution scale from 40% to 200%;
  
• NEW Moving alignment indicator helper;
  
• NEW Cute environment background for the editor;
  
• NEW Multiscreen support, DPI agnostic for different DPI settings across screens. Resist screen disposition and dpi scale changes;
  
• MI removes edge artifacts between connected blocks;
  
• MI chromatic aberration on blocks (can be deactivated);
  
• MI Optimizing renderer for scale;
  
• FIX Low settings renderer fast now;
  
• FIX CRT effect edge artifacts;
  
• FIX Free camera was clipping far objects;
  

[h2]3. UPDATED Readouts but more better 👌[/h2]
Readouts are a centerpiece of HC. They allow you to interact with your solutions. Naturally, many new developments were made to further their usefulness.

The new Breakpointable Readout feature makes debugging more manageable. You can now set breakpoints within your solution, making it easier to trace the execution flow and stop the simulation at potential issues.

Also, readouts rotate/flip (when attached to a blueprint) and can be Undo/redo!

Rotate/flip...


...and Undo redo!


Changelog:

• NEW Undo/redo for readouts;
  
• NEW Breakpointable readout;
  
• UX Readouts lines properly align on nbit readouts;
  

[h2]4. UPDATED Simulation tweaks[/h2]
Nothing too big, but small changes still. Shorts are now guaranteed to show up where before they could appear and disappear in one single frame. Also, Inputs now spend 1 tick in neutral before going to an opposite state.

We are also introducing a new secondary metric: Energy Loss! It characterizes the sum of blocks in a loaded state (when 1 and 0 states connect) for each tick.



Changelog:

• NEW Energy loss in perf report;
  
• SIM Inputs spend 1 frame in neutral when changing to the opposite state;
  
• SIM Blocks in the "loaded" state last at least one frame now;
  
• UX Animation on perf reports;
  
• MI terminal shader pass speed improved;
  

[h2]5. NEW Other not so trivia points[/h2]
The main branch of HC is its readying process. Steam already validated the build, meaning people can now receive keys (wink wink 😉 if you create video game content).

To share data between the Main, Demo, and Playtest branches, every savefile was moved to %LocalAppData%. A more standard approach. If you have any savefile, an updater can help you recover the file from the previous location.

The demo isn't left aside! It gets regular updates as soon as the playtest build is stable enough to be the base for a new demo build. It is now at version 0.0.6.8 and should be updated soon.

Changelog:

• MI Adding "Quick Updates" notes on the main menu to explain the new location for save and its updater.
  
• MI Tutorial challenge load/save into a separate folder so they don't appear in the Library anymore;
  
• MI Library uses a new location for new Chips/Bluprints;
  
• MI All challenges savefiles are in the "Chips" data folder; Tuto is in the "Tutorial" one;
  

[h2] Never-ending Quality Of Life, Bug, and Crash fixes list:[/h2]

Greetings, Hard Chip players!

Let's cover the modifications made in versions 0.0.5.58 to 0.0.5.64 and the move to 0.0.6.0! It has been three weeks since the last update, so this update is packed with improvements, new features, and fixes designed to enhance your experience. Here's a detailed look at what's new:


[h2]1. UPDATED Camera controls and keyboard controls[/h2]
The strongest feedback was about controls: " I love the concept of this game, but the controls are too unresponsive." "Controlling this was..... awful, frankly. I'm really really excited by the concept." "I, too, like the demo but was hampered by the controls."
Okay, controls need reworking! That is precisely one of the past weeks' focus areas. It might be hard to show every change with gifs, but I put every change in the "Changelog" section below for the courageous ones.





Changelog:

• NEW Recenter/Dramatic moves/ShowHideUIElements camera control buttons;
  
• NEW Key shortcuts 123456 to Traces, PMOS, NMOS, etc...
  
• NEW Camera Tilt/Pedestal movement on ZC;
  
• MI Mouse and keyboard revert to a suspended state when the window is unfocused;
  
• MI Camera finishes its movement even when the window is unfocused; no mouse wheel is captured when the window is unfocused;
  
• FIX Mouse swing when entering a level;
  
• FIX Force mouse pos in center to avoid "cropped" moves in FPS phases;
  
• FIX Camera rubber band movement effect when low framerate;
  
• FIX Camera center broken after switching from free cam;
  
• UX When the mouse is locked, last state = current state, to avoid big swings;
  
• UX UI captures keypress for textboxes only, making shortcuts work even if the mouse is on the UI;
  
• UX Tab switches between modes;
  
• UX Rotate camera control button now changes the angular momentum of the camera;
  
• UX Editor/Freecam button shows the actual mode the cam is in;
  
• UX Camera zooms when at die level;
  
• UX Camera movement buttons are now the same as with the mouse;
  
• UX Camera keyboard maps to the new camera behavior;
  
• UX Camera framerate agnostic fix for rotation;
  
• UX Camera angular behavior tweaking;
  

[h2]2. NEW Slots[/h2]
It's a must-have feature to have for a game like HC. Now you can have up to 3 slots per challenge to test different designs without having to use blueprints as a workaround:



And it allows some cool "side effect" like copying pasting between slots:


Changelog:

• NEW Per slot Undo/Redo stack;
  
• NEW 3 save slots for challenges!;
  
• MI Slots for Challenges only;
  
• FIX Selection now resets when switching slots;
  

[h2]3. NEW 5 Challenges[/h2]
More challenges were added to the existing ones, bringing the total to 36 challenges (+12 for the tutorial ones).

- NEW Nible multiplier challenge, a good stepping stone to the 8bits multiplier!

- NEW 2/4/8 bits transmitter challenges—those are really useful as a blueprint when you work with buses!



- The NEW 64Bit adder challenge is genuinely enormous; floor planning and excellent blueprints are required for this one! "Work smarter not harder" type of challenge.





[h2]4. UPDATED Demos (partially)[/h2]
For a long time, Demos accessible in the Library in the main menu were disabled. They were built with an outdated HC simulation and weren't functional anymore. That's fixed! Well, almost. They all have properly shaped circuits, but only half are in working condition. So work in progress! But you can have fun with an adder, decoder, and the famous 512-byte RAM module (which is the maximum target size for an HC circuit at the moment).



Here's a now properly shaped demo, but needs rework of part now. Still cool I found:



Changelog:

• MI Demos run the simulation and show readouts now;
  
• MI Converting all demos to Conducive Gate update and Distinct MOS Connection update;
  

[h2]5. UPDATED MOS Behavior and looks[/h2]
The demo available during the Next Fest was a fantastic developer experience. The variety of solutions for even the most straightforward challenge (the demo ended after the NAND challenge) was an absolute joy to see!
Some people have even found some nice exploits! For a long time, I didn't want to fix those exploits because you had to think smart to come up with them in the first place. But HC is about being as close to reality as possible, and those exploits didn't reflect reality much.

Here's the set of merge that was working before 0.0.6.0:



As you can see, on the left 2 merge PMOS are still valid. On the right merging PMOS and NMOS isn't possible anymore where previously it was functional.

Changelog:

• UX Gates has the same color as the type of MOS;
  
• NEW Savefile updater in the settings to allow players to update to Distinct MOS connection modification;
  
• FIX Merge Gate Exploit;
  
• FIX Merge MOS Connection Exploit;
  
• FIX Connected gates rendering are always visually connected;
  

[h2]6. NEW Unconnected indicators and Select Segment[/h2]
It's a pain to find unconnected transistors at scale. But that's a thing of the past now! Welcome the new "Floating pin indicators," which are visible from anywhere and on top of everything else.

The "Select Segment" isn't a new feature per se but more of a forgotten one. In fact, no one seems to know that it existed! Here's a small tweak to change that:



And the new indicators



Really handy for certain situations! Like here a missed PMOS connection in a sea of wires!


Changelog:

• UX Adding select segment into the selected modal;
  
• UX Clearer color and blinking selected block indicator;
  
• NEW Floating pin indicators;
  

[h2]Quality Of Life, Bug, and Crash fixes:[/h2]

• Quite a lot of additions were made, and more than could be possibly covered in a reasonably short dev blog post. But for reference, here are the rest of the changes made in the last weeks:
