CC: Wasm (Unofficial port)

by SteamAutomata

CC: Wasm (Unofficial port) brings WebAssembly modules into CC: Tweaked, so computers can load and run .wasm files on NeoForge 1.21.1.

What it does

A computer script can load a compiled WebAssembly module from a folder in the world save and call functions exported from it. The module is run by the Chicory runtime, which the mod adds to CC: Tweaked so the work happens inside Lua programs without any extra setup on the player's side. Module files are named with the .wasm extension and are passed to the load function by name.

The port is a NeoForge build for Minecraft 1.21.1 only, with CC: Tweaked as its required dependency. It was made to change as little of the original project as possible, so the code differs only where the modloader and this Minecraft version require it. The mod uses the ASM library that NeoForge provides. Because CC: Tweaked must be present, a server needs it as well as this mod.

Its source code and issue tracker are public, and the author notes that the port could become a separate fork that receives its own fixes and features. Contributions are welcome.

Key features

  1. WebAssembly modules in Lua

    Scripts running on a computer can load .wasm files from the world folder and call the functions they export.

  2. Chicory runtime

    The Chicory WebAssembly runtime runs the loaded modules inside CC: Tweaked, so no separate program is needed.

  3. Minimal port changes

    The code is kept close to the original project and changed only where the NeoForge loader or 1.21.1 require it.

  4. Public source for contributions

    The source code and issue tracker are public, and the author welcomes contributions toward improving the port.
