ocgcore-wasm v0.0.34

ocgcore-wasm

ProjectIgnis' EDOPro Core built for WebAssembly using emscripten.

The async version requires JS Promise Integration (JSPI) and Type reflection. Use the flag --experimental-wasm-stack-switching with node.

Example

Initialize sync version

const scriptPath = "...";
const cards = loadCardDatabase();

const lib = await createCore({ sync: true });

const handle = lib.createDuel({
  flags: OcgDuelMode.MODE_MR5,
  seed: [1n, 1n, 1n, 1n],
  team1: {
    drawCountPerTurn: 1,
    startingDrawCount: 5,
    startingLP: 8000,
  },
  team2: {
    drawCountPerTurn: 1,
    startingDrawCount: 5,
    startingLP: 8000,
  },
  cardReader: (code) => {
    const card = cards.get(code);
    if (!card) {
      console.warn("missing card: ", code);
    }
    return card ?? null;
  },
  scriptReader: (script) => {
    const filePath = script.match(/c\d+\.lua/)
      ? path.join(scriptPath, "official", script)
      : path.join(scriptPath, script);

    try {
      return readFileSync(filePath, "utf-8");
    } catch (e) {
      console.log(`error reading script "${script}", ${e}`);
      throw e;
    }
  },
  errorHandler: (type, text) => {
    console.warn(type, text);
  },
});

if (!handle) {
  throw new Error("failed to create");
}

Processing

await lib.startDuel(handle);

while (true) {
  const status = await lib.duelProcess(handle);

  const data = lib.duelGetMessage(handle);
  data.forEach((d) => console.log(d));

  if (status === OcgProcessResult.END) {
    break;
  }
  if (status === OcgProcessResult.CONTINUE) {
    continue;
  }

  // send response
  lib.duelSetResponse(handle, getNextResponse());
}
