CAAT – Tutorial 2, Behaviors

Hey hyperandroid,

i’ve tried to do a very simple animation with CAAT. I’ve clicked and search through most of the samples on the tutorial page, but didn’t find the error of my code. Would be great if you or anyone else could help me…

cheers!

The Error is:
- his.path.getPosition is not a function
- var point= this.path.getPosition(time);
- caat.js (Zeile 3779)And thats the code:

    // DRAW THE CANVAS
    var director = new CAAT.Director().initialize(
        600,    // 100 pixels wide
        340,    // 100 pixels across
        document.getElementById(‘canv’));
       
     // CREATE FIRST SZENE
    var scene_bg = director.createScene();       

    // DECLARE COLORS
    var bmwgrey = ‘#888′;
    var bmwstreet = ‘#ccc’;
   
     // PAINT BG
    var bg = new CAAT.Actor().
        setBounds(0,0,600,340).
        enableEvents(false);
    bg.paint = function() {
        var ctx = director.ctx;   
        ctx.fillStyle = bmwgrey;
        ctx.fillRect(0,0, 600, 60);
        ctx.fillRect(0,280, 600, 60);
        ctx.fillStyle = bmwstreet;
        ctx.fillRect(0,60, 600, 220);
        ctx.fillStyle = “#FFF”;
        ctx.fillRect(0,60,600,3);
        ctx.fillRect(0,277,600,3);
    }
    // create a line
    line = new CAAT.ShapeActor().
          setLocation(20, (director.height / 2) – 4).
          setSize(100, 8).
          setShape(CAAT.ShapeActor.prototype.SHAPE_RECTANGLE).
          enableEvents(false).
          setFillStyle( ‘#FFF’ );
       
    // create a path.
    movingPath= new CAAT.PathActor().
    setBounds(0,0,600, 340).
        create().
        setPath(
            new CAAT.Path().beginPath(20,(director.height / 2) – 4).addLineTo(580, (director.height / 2) – 4).endPath().
        setInteractive(false));

    // moving the line
    var path_behavior= new CAAT.PathBehavior().
            setPath( movingPath ).
            setFrameTime(0,5000).
            setCycle(true).
            setAutoRotate( false );
   
    // ADD shapes and stuff
    scene_bg.addChild (bg);
    scene_bg.addChild(line);
    scene_bg.addChild( movingPath );
    line.addBehavior(path_behavior);
 
 
CAAT.loop(30);
