Available imports and exports - Xendergo/Minecraft-wasm-runtime GitHub Wiki

If you want your code to reload automatically when you change it, export an i32 call it autoReload, and set it to 1.

Example:

export const autoReload: i32 = 1;

This is also checked each time the file changes, so you're welcome to change this dynamically if you want to do that for some reason.

With this, you can print all numeric types in wasm to chat, and you can import as many arguments as you like, with whatever types you like.

Example:

declare function print(a: i32, b: i64, c: f32): void;

export function thingy(v: i32): void {
  print(v << 1, (<i64>v) << 32, <f32>Math.sqrt(v));
}

With this, you can print one string to chat.

Example:

declare function printString(v: String): void;

export function thingy(v: i32): void {
  printString(a.repeat(b * 3));
}
