GODOT ASTEROIDS

Export as Web with compressed wasm

• Export project as Web (without Extension Support, For Desktop). Make sure the html file name is asteroids.
• Gzip asteroids.wasm and rename it again to asteroids.wasm
• Download Pako https://raw.githubusercontent.com/nodeca/pako/master/dist/pako_inflate.min.js
• Open asteroids.html and add this <script type="text/javascript" src="pako_inflate.min.js"></script> line just before the line <script type="text/javascript" src="asteroids.js"></script>
• Open asteroids.js and edit this function like this:

	function loadFetch(file, tracker, fileSize, raw) {
		tracker[file] = {
			total: fileSize || 0,
			loaded: 0,
			done: false,
		};
		return fetch(file).then(function (response) {
			if (!response.ok) {
				return Promise.reject(new Error(`Failed loading file '${file}'`));
			}
			const tr = getTrackedResponse(response, tracker[file]);
			if (raw) {
				if (file === "asteroids.wasm") {
					return Promise.resolve(tr.arrayBuffer().then( buffer => {
						return new Response(pako.inflate(buffer), { headers: tr.headers })
					}));
				} else {
					return Promise.resolve(tr);
				}
			}
			return tr.arrayBuffer();
		});
	}

Compressed wasm required due to 25 Mb file size limitation. Additionally, you must rename asteroids.html file to index.html, and you must create a file _headers with the following:

/*
	Access-Control-Allow-Origin: *
	Cross-Origin-Opener-Policy: same-origin
	Cross-Origin-Embedder-Policy: require-corp
