24 alternatives to Use OpenAI's 4o to create game assets, publish to Creative Commons
I made a huge breakthrough in sprite animation today. I originally asked image models to generate all the frames of a spritesheet corresponding to an animation (e.g., "running to the left" or "jumping") in one image. It didn't really work. Only about 10% of the time would it give me a satisfactory result. Then, I tried to generate all the frames with separate requests to the model in a loop, passing in all the other frames for reference. This significantly improved the likelihood of the model getting the animation correct on a conceptual level. But the subject in each frame was perceptibly…

I tried to build AI game animation generator last year ( https://news.ycombinator.com/item?id=40395221), a lot of people were interested, but it failed, mainly because the technology was not good enough. 1 year passed, there were a lot of developments in video/image generation. I tried it again, I think it works super well now. Actually beyond my expectation. You can generate all kinds of game character animation sprites with only 1 image. 1, upload your image of your character 2, choose the action you want 3, generate! Support basic actions like Run, Jump, Punch and…

Hi HN! 2d spritesheets for game development are often distributed as a PNG image, sometimes with a separate JSON or XML metadata document describing the layout, including any animation sequences within the sheet. Sometimes there is no metadata document and you have to work it out and manually write custom code to chop up the spritesheet and reference the sprites you want. I think it would be good if it became standard practice to distribute spritesheet PNGs with the metadata inline inside a PNG "chunk" so the whole thing is self-contained. That way artists can just distribute one file, and…

I tried to train text to video and image to video models to generate 2D game animations. I used public game animation data and 3D mixamo model rendered animations to train the animation generation models. I'm open sourcing the model, training data, training code and data generation code. More technical details can be found in my blog (https://www.gavinliblog.com/posts/godmodeanimation).

We added a new feature to our open-source HTML5 game engine today that allows you to create Sprite GPU Layers. These pack together simple JS object definitions onto the GPU and renders them using a custom vertex shader. This skips all CPU computation and GPU upload operations, resulting in vastly increased performance. For objects that don't need to be updated by input, physics, or other interactive behaviors, we found it to be a great solution. In testing, we've easily managed to blast millions of sprites around on moderate desktop-grade GPUs. Indeed, we hit the fill rate limitation of the…

I've been working on a CSS Sprite generator for a couple of weeks in my spare time. It uses HTML Canvas and JavaScript FileReader to open local images without any zipping or uploads, and tries to make the CSS generation as easy as possible. I made it because it is a tool that I wanted to have, and I am hoping to get some feedback from others now that it is functional. http://instantsprite.com

IMAGEAT AI▲28I built a small free tool that converts images into structured JSON output. The idea is simple: upload an image, and the tool tries to extract its visual/content information into a clean JSON format that can be used for further processing, automation, or AI workflows. This started as a side project to speed up my own experiments with image analysis and prompt pipelines. There’s no login, no paywall, and it runs entirely in the browser. I’m sharing it here mainly to get feedback: Does the output structure make sense? What use cases would you expect from something like this? Anything…

one-off image/video generation is easy, but creating a cohesive story with consistent characters and locations across multiple scenes is difficult. So I am building flickspeed.ai which provides a infinite canvas with image/video/audio nodes where you can create base characters and then use it across multiple scenes. there is also an agent which assist in writing prompts Feedback, bugs, and suggestions are all welcome.
