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 outside 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);
});
