LÖVE API in javascript
loveJS
A copy of the LÖVE API into javascript.
WARNING
This port requries you to use Javascript. You were probably looking for love.js, the version that uses Emscripten and is way better. You can find that here.
Installation
Download the love.js in the build folder.
<script type="text/javascript" src="love.js"></script>
If you're a beginner with javascript, here's what your index.html should look like:
<head>
<meta charset='utf-8'>
<title>Game</title>
<!-- The order in which files are loaded is important! love.js first! -->
<script type="text/javascript" src="love.js"></script>
<!-- main.js is the file where you put in love.update and love.draw (see usage) -->
<script type="text/javascript" src="main.js"></script>
</head>
<body>
<canvas style="border:1px solid #000000;" id="canvas" width="1024" height="768"></canvas>
</body>
</html>
love.js and main.js should be in the same folder as index.html
Usage
Put this in your main.js
//Preload images here
love.graphics.preload();
//Preload audio here
love.audio.preload();
//Called when preloading is done
love.load = function () {
}
//The main updater
love.update = function (dt) {
}
//The draw loop
love.draw = function () {
}
//Configure canvas width and height
love.config = function (t) {
t.width = 800;
t.height = 600;
}
//Initialize love
love.run();
Look in the example folder for a better explanation.
