liberatedpixelcup/universal-lpc-spritesheet-character-generator is a generator that combines LPC character art pieces on the basis of Universal-LPC-Spritesheet. You can create characters for walking and attacking animations, and try it out right on the web. The latest publicly released version is not stated in the provided information. The implementation language of this repository is TypeScript.
The core of this tool lies not in drawing new art but in gathering and combining LPC character art that already exists. A sprite sheet is an image that collects the picture frames used for animations, and a character is built by combining multiple pieces. The README explains that you can gather and combine the LPC character art made so far, and that other LPC art such as tilesets can be found on OpenGameArt.org. The repository shows 1951 stars, and the license is GPL-3.0.
The terms of use include artist attribution. The README states that when using LPC sprites you must credit all the artists who contributed. So when using the combined result, you need to check this attribution requirement. This project is closer to a generator that assembles existing LPC assets than to a drawing tool.
