# gui-dat
**gui-dat** is a lightweight controller library for JavaScript. It allows you to easily manipulate variables and fire functions on the fly.
## Basic Usage
<script type="text/javascript" src="demo/demo.js"></script>
<script type="text/javascript">
window.onload = function() {
var fizzyText = new FizzyText("gui-dat");
GUI.start();
// Text field
GUI.add(fizzyText, "message");
// Sliders with min and max
GUI.add(fizzyText, "maxSize", 0.5, 7);
GUI.add(fizzyText, "growthSpeed", 0.01, 1);
GUI.add(fizzyText, "speed", 0.1, 2);
// Sliders with min, max and increment
GUI.add(fizzyText, "noiseStrength", 10, 100, 5);
// Boolean checkbox
GUI.add(fizzyText, "displayOutline");
// Fires a function called "explode"
GUI.add(fizzyText, "explode").name("Explode!"); // Specify a custom name.
};
</script>
+ ui-dat will infer the type of the property you're trying to add (based on its initial value) and create the corresponding control.
+ The properties must be public, i.e. defined by `this.prop = value`.
Monitor variable changes <i>outside</i> of the GUI
--------------------------------------------------
Let's say you have a variable that changes by itself from time to time. If you'd like the GUI to reflect those changes, use the listen() method
GUI.add(obj, "propName").listen();
## Fire a function when someone uses a control
GUI.add(obj, "propName").onChange(function(n) {
alert("You changed me to " + n);
});
