This is a library for reading, rendering and playing Elasto Mania .lev and .rec files.

Previous versions used source files implemented in AMD form (asynchronous module definition) with no necessary build process, and a basic "amd.js" loader was provided.

The current version is implemented in TypeScript using ES6 modules, but a drop-in standalone "amd.js" file can be built using:

npm install
npm run amd-fake

Correct rendering depends on various images that are normally part of an .lgr file. There should be a gh-pages branch in this repository with an images directory containing images derived from the lgrdk10.zip distribution of the LGR development kit. Note that these images however have a higher pixel depth (24-bit) than the ones used in the actual game (possibly 8-bit mapped?).

Install package from git repository:

npm install git+https://github.com/Maxdamantus/recplay

Render level stuff/chainpi3.lev and play replay stuff/chainpi3adi.rec, assuming LGR images are accessible in the images directory:

import * as controller from "recplay/lib/controller";

document.addEventListener("DOMContentLoaded", () => {
	const target = document.body.appendChild(document.createElement("div"));
	controller.make("stuff/chainpi3.lev", "images", target, document)(cnt => {
		cnt.resize(1024, 768);
		cnt.loadReplay("stuff/chainpi3adi.rec", []);
	});
});

Various sample usages are also included in the gh-pages branch.

The update-gh-pages.sh script can be used to easily experiment with changes:

npm run amd-fake && ./update-gh-pages

This will build and populate a gh-pages directory based on the latest version of the gh-pages branch (containing images and sample pages) with the new version of "amd.js".

In older browsers, the sample pages could be viewed locally using file:// URIs, but nowadays an HTTP server must be used, eg:

python3 -m http.server -d gh-pages/
