Description

this crate is for cc wasm mod

Usage

• add this crate as a dependence.
• set [lib]-crate-type to "cdylib"
• build with --target wasm32-wasip1 (rustc 1.97+ renamed wasm32-wasi to wasm32-wasip1)
• copy target/wasm32-wasip1/release/[crate name].wasm to .minecraft/wasm/
• load it in game: wasm.load_wasm("[crate name]") or run exec_wasm [crate name] in a computer shell

Features (all opt-in, default = coroutine + eval + addon)

• coroutine — provides tick / stopped exports so exec_wasm / exec_wasm_aot can drive your module's event loop. required when the wasm program is driven by exec_wasm.lua.
• eval — call back into Lua: eval_string / eval_result round-trips between wasm and Lua. no longer forces coroutine; can be enabled alone.
• addon — local monitor (LocalMonitor), vec2d, time, ColorId helpers etc.
• debug — debug output helpers (show_str / show_debug).

Example

please see the example here (minesweeper / pic_display / txt_display / python / obj_demo / type_test).

Notes

• Lua numbers always arrive as f64; numeric adaptation (cross-type conversion + int/range checks) lives in the i32/i64/f32/f64 imports of lua_api (Number accepts anything).
• strings are passed as raw bytes (utf8-safe); the CC terminal display layer may still show non-ascii as ?, but data round-trips losslessly.
