Playing around with a Trenchbroom / func_godot / Godot physics game thing. #prototype #gamedev

Glad you're finding it useful, thanks for sharing!

Uh oh, started down the "I should build a voxel game" rabbit hole. #gamedev

First build of my web app "func_terrain" is live: tools.ummjackson.com/func_terrain

It lets you quickly generate noise heightmap-based terrain then copy/paste it as brush data directly into #Trenchbroom

Completely free to use / whatever you make is yours, etc. #gamedev

CANYON by Jackson Palmer Survive the CANYON

Just posted my submission to the @gamemakerstoolkit.com GMTK Game Jam 2025: ummjackson.itch.io/canyon

Built using Godot 4.4 @godotengine.org #gamedev

Sounds good! Eagerly awaiting trying it. :)

Ah gotcha, thanks for the answer. Half-Edge looks super rad but is it level design focused? The world really needs something like Trenchbroom but for modern formats (ie. no FGD, WAD, .map/.bsp stuff).

Is there a possibility of Scythe becoming a standalone app in the future, or is it too intertwined with the UE editor? The world is in need of a tool like this which exports to GLTF, which can be used in a variety of engines.

The "manual" mode sticks to a uniform grid you can move around and resize by holding the shift key.

The "auto" mode uses some advanced edge-detection and line clustering powered by OpenCV.js, all running in-browser. Had fun porting this logic over from the Python library github.com/KennethJAlle...

You can use it entirely free @ tools.ummjackson.com/pixelizer

For those interfaced, the procedure is pretty simple: we overlay a virtual pixel grid over the top of the high-res image, then find the dominant colors in each cell of the grid to essentially "redraw" the pixel art image.

(If you're anti-AI, please avert your eyes)

Just released a web app that takes AI-generated "pixel art" (high-res, noisy/artifact-y) and turns it into actual pixel art. Here's a demo video. #gamedev #ai

Also works well for low-quality screenshots of pixel art you might randomly fine online.

OK the new Tyler album is fire.

Built this as I needed something for quick #trenchbroom / func_godot prototyping. Can slap a basic texture set together in under 10 minutes then get to mapping. #gamedev

Sidenote: Performance isn't *the best* right now as it's all running on the CPU / main thread. Future todo is handing the processing off to Web Workers and doing some multi-threading for about a 4x speed increase.

As you can see in the demo video, I'm getting decent results just screengrabbing and pasting random parts of images from Pexels. Any feedback, bug reports appreciated. 🙂

You can try it out @ tools.ummjackson.com/texture/tiler

It includes pixel-level synthesis (good for organic textures), patch-based synthesis (good for maintaining grains, etc.) and several processing modes like offset + seal and simple alpha gradient blending (good for tiles, bricks etc.)

Just pushed the first build of my Texture Tiler tool for easily creating seamless tiling textures based on an input image. Here's a quick demo video to show what it can do. #gamedev #textures

Just discovered this open-source voice to text app powered by Whisper that runs everything locally on Apple Silicon machines. No-nonsense, minimalistic UI. Just drops the transcription directly into what ever app / text input area you have focused. Really great stuff.

Texture Grabber Build 1 is now live @ tools.ummjackson.com/texture/grab...

If you've used something like Shoebox Texture Ripper in the past, this should feel quite familiar - but running in your web browser.

Feedback & bug reports appreciated. #gamedev #texturing

Making progress on my texture grabber web app. UI and workflow is feeling pretty decent at this point. Decided against including an atlas packer for now as there are many out there already - you can download a single texture as a PNG or get a .zip of them all. #gamedev #textures

"Scratch" - a lightweight, tabbed Markdown scratchpad with local persistence I initially built for personal use. I've kept it open as a pinned tab for the past 6 months and find it a convenient place to copy/paste and edit plain text, store todos, etc. #dev

thank you! hope it’s useful for people.

Shout out to FOOTSTEPPR (games.increpare.com/footsteppr/i...) which inspired the multi-stage impacts of TAP. Awesome tool, kudos to @increpare.bsky.social

I personally couldn't find another tool quite like TAP, which was my motivation behind it - here's a quick demo showing how quickly you can craft UI click and pop sounds through to footsteps. I'm using the hotkeys btw (underlined button characters). #gamedev

tools.ummjackson.com/noise/tap

I'm still having fun just sitting around repeatedly tapping the "R" key to hear all the random noises these can generate. They're also responsive so work on mobile devices.

100% free and do whatever you want with the exported .wav files. Hope someone out there finds them useful. :)

THUD simulates a drum-like membrane to create a range of percussive sounds.

DING uses modal synthesis to generate resonating bells, chimes, plucks, etc.

TAP creates multi-stage impulse sounds like taps, footsteps, shakes, and more.

#gamedev #sounddesign

I've been looking for something more "organic" sounding than sfxr, so threw together a few small, free tools to generate all sorts of random noises and sound effects. Might come in handy for game jams, UI sound effects, etc. #gamedev

Removed the snap-to-grid from my texture grabber web app and it feels tidier... now just rendering a grid inside selection area to help with lining up perspective. #weekendproject #gamedev

I'm interested in how many people who use older tools like Shoebox would benefit from a "snap to grid" feature... my current implementation works but I don't find myself using it very often. Feedback appreciated. #gamedev
