addChild(player2 , kTagSprite );

}

@Override
public boolean ccTouchesBegan(MotionEvent event) {
//create point takes coordinates of touch
CGPoint convertedLocation = CCDirector.sharedDirector()
.convertToGL(CGPoint.make(event.getX(), event.getY()));

CCNode s = getChild(kTagSprite);
s.stopAllActions();
s.runAction(CCMoveTo.action(1.0f, convertedLocation));

return CCTouchDispatcher.kEventHandled;
