Welcome to zombocom. The only limit is your self.

This engine is very simple. Each iteration through the game loop updates and draws each object.

Current How To

Step 1: Make a "class"

```javascript

// give your "class" an awesome and unique name
function AwesomeBox(attributes) {
  // save any attributes to the object
  this.attributes = attributes
  
  // set up the shader. fetches the pair basic.vs and basic.fs
  this.shaderName = "basic";

  // set static attributes like vertices, normals, or texture coordinates
  this.vertices = [0.0,  0.0,  1.0,
		  0.0,  0.0,  1.0,
		  0.0,  0.0,  1.0,
		  0.0,  0.0,  1.0];


  this.attributeCount = 4;

  // this call inherited from GameObject3D, adds the object to be updated and drawn
  this.init3d();

  // optionaly override the update call. Use this to compute any state changes for your object
  this.update = function() {
    // game.tick is the current iteration through the game loop.
    // use this to measure time, as Date.now() will break if the game gets paused
    if (game.tick - this.lastDoStuff) {
      // do stuff...
      this.lastDoStuff = game.tick;
    }
  };

  // if your object exists visualy in the world, override this function
  this.draw = function() {
    // push the model view matrix
    mvPushMatrix();

    // perform translations or rotations
    //    mat4.translate(mvMatrix, ...
    //    mat4.rotate(mvMatrix, ...

    // draw dat stuff
    draw3d();

    // clean up and leave
    mvPopMatrix();
  }
}
// this causes the object to inherit the base object class, giving it access to 
// init, update and draw calls. 
AwesomeBox.prototype = new GameObject;
```

Step 2: Make a game

```javascript
// First setup any initial game objects

// when the object is created, the init() call will add the object to the manager,
// and when the game is started it will be updated and drawn accordingly. 
var awesomeBox = new AwesomeBox();
// to remove the object, use awesomeBox.shutdown()

// Then start the game. Tts that easy.
game.start();
```
