See this example, where the sprite will go to the mouse click position: http://groups.google.com/group/cocos-discuss/web/test_ball_mouse_driven.py You can look at cocos.actions.move actions and the associated test_tiles.py for an example on driving a sprite with actions. Naturally,it is also posible to control the sprite with the classic class MySprite(...): def update(self, dt): your code which can be more flexible if you have complex animation code. -- claudio -- You received this message because you are subscribed to the Google Groups "cocos2d discuss" group.
