Support for Zwoptex plist file format.

[inc]

This adds basic support for Zwoptex sprite sheet coordinates plists with the XML cocos2d coordinates format.

Great news, I will test this when I have more time.

I created a sprite sheet through the flash version of Zwoptex, I put the two files (grossini_dance.png and grossini_dance.plist) in /assets/, but the following code seems not work:

public class HelloWorldLayer extends CCColorLayer {

    protected HelloWorldLayer(ccColor4B color) {
        super(color);
        this.setIsTouchEnabled(true);

        //cache
        CCSpriteFrameCache cache = CCSpriteFrameCache.sharedSpriteFrameCache();
        cache.addSpriteFrames("grossini_dance.plist");

        //frame array
        ArrayList<CCSpriteFrame> framesArray = new ArrayList<CCSpriteFrame>();
        for(int i=1; i<15; i++){
            String frameName = String.format("grossini_dance_%02d.png", i);
            CCSpriteFrame frameObject = cache.spriteFrameByName(frameName);
            framesArray.add(frameObject);
        }

        //animation object
        CCAnimation animObject = CCAnimation.animation("dance", 0.3f, framesArray);

        //animation action
        CCAnimate animAction = CCAnimate.action(animObject, false);
        CCRepeatForever repeatAnimAction = CCRepeatForever.action(animAction);

        //sprite
        CCSprite grossini = CCSprite.sprite("grossini_dance_01.png");
        grossini.setPosition(CGPoint.ccp(C.SUPPOSED_WIN_WIDTH/2, C.SUPPOSED_WIN_HEIGHT/2));

        addChild(grossini);

        grossini.runAction(repeatAnimAction);

    }

    public static CCScene scene() {
        CCScene scene = CCScene.node();
        CCLayer layer = new HelloWorldLayer(ccColor4B.ccc4(255, 255, 255, 255));

        scene.addChild(layer);

        return scene;
    }
}

From the logcat:

If I put all 14 files in the assets directory the animation is displayed correctly (but this way I'm not using the sprite sheet),

Is this a library bug or is my code wrong?

[leinardi]

I'm sorry, I just found the bug by myself: It was wrong the path of the sprite:

        //sprite
        CCSprite grossini = CCSprite.sprite("grossini_dance.png");
