gamekit's Issues

Is this still maintained?

Hi,

stumbled across your framework and was wondering if this is still being maintained.

AMD/UMD instead of crazy //@@include stuff

Established module patterns may be more useful than strange replacing.

If proper modules were used, I could see using this with FrozenJS

Write unit tests

Hey @Paratron, I'm writing some unit tests on Jasmine and getting it to work with Grunt. In one day or two, I'll make a pull request including them :)

Custom build downloads php file

When trying to use the custom build the download gives me a corrupted download.php file instead of a archive javascript

Error: gamekit.js:2801 Uncaught TypeError: Cannot read property 'call' of undefined

I'm working with a forked cop of your framework and with the following logic

gamekit.defineModule("main", function(){
    function setup(){
        gamekit.a.rejects = new gamekit.SpriteMap({
              image: gamekit.a.rejects,
              tileW: 400,
              tileH: 400,
              offsX: 0,
              offsY: 0
          });
        var reject2 = new gamekit.Sprite(gamekit.a.rejects[2]);

        gamekit.clearCanvas();
        gamekit.createLayer();
        gamekit.layer[0].attach(reject2);
    }

    var p = gamekit.loadAssets('characters.assets.json');
    p.then(setup, function(){
      console.log('error', arguments);
    }, function(){
      console.log('progress', arguments);
    }).then(gamekit.start);
});

Everything loads as expected but I get an error

gamekit.js:2801 Uncaught TypeError: Cannot read property 'call' of undefined
at gamekit.Sprite.update (gamekit.js:2801)
at GamekitLayer.draw (gamekit.js:1224)
at mainLoop (gamekit.js:263)
update @ gamekit.js:2801
draw @ gamekit.js:1224
mainLoop @ gamekit.js:263

checking the line @ 2801

the this in this._update.call(this); refers to a Sprite.object

gamekit.Sprite {
false
direction
:
NaN
friction
:
0
h
:
400
life
:
NaN
originX
:
0
originY
:
0
rotation

scaleX

scaleY
:
NaN
speed
:
NaN
stretch
:
false
w
:
400
x

y

}

any reason why this is happening? should Sprite have an ._update function?
