动画有三个状态 “左行” “右行” 和“空闲”
1. 当摇杆左拨动 即konb x <0 人物播放左行动画 并且左移动且 X 与 0之间的绝对值越大 人物移动速度越快
2. 当摇杆右拨动 即 konb x >0 人物播放右行动画 并且右移动 且 X 与 0之间的绝对值越大人物移动速度越快
3. 当摇杆左+上拨动 即konb x <0 Y>0 人物播放左行动画 并且左上移动且 X,Y 与 0之间的绝对值越大 人物移动速度越快
4. 其余同理..
5. 当摇杆左+下拨动 即konb x <0 Y<0 人物播放左行动画 并且左下移动且 X,Y 与 0之间的绝对值越大 人物移动速度越快
6. 当X轴无变动时候(即便Y轴有变动)播放 “空闲”动画 (若Y轴有变动,改变人物Y轴坐标)
之前弄了能播放动画却无法改变坐标
现在搞了一晚上能改变坐标却不能播放移动时候的动作动画

哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈 已经解决 可以安心睡觉了

万能的group 仿写这个就好了

//后面这段代码没有生效
}else if(touchpad.getKnobPercentX()*speed<0){
state=STATE.Left;
sprite.setRotation(sprite.getRotation()+1);
}
