我正在使用http://craftyjs.com/进行 Github Game Off,但我在动画方面遇到了一些问题。我第一次开始动画时(当我在主场景中初始化玩家实体时)它起作用了。但是当我通过我的 CustomControls 组件设置动画时,它只播放动画的第一帧。
我相信问题出在 CustomControls 组件中,所以这里是代码: https ://gist.github.com/3992392
如果你想克隆它并测试,这里是所有代码:https ://github.com/RylandAlmanza/dragons-suck
如果有人知道问题可能是什么,请告诉我。谢谢!
编辑:这是一个最小的 jsfiddle 示例,除了运动和应该是动画之外的所有内容:http: //jsfiddle.net/x7FDF/
