I would probably do this instead:
- remove the constraints
 
- make on bone for one bullet
 
- animate the movement for one bultet doing exactly the complete sequence you need
 
- duplicate the bone and the animation
 
- offset the animation
 
- adjust the draw order
 
我可能会这样做:
-消除约束
-用一颗子弹做骨头
-动画化一个短棍的运动,完全按照您需要的顺序进行
-复制骨骼和动画
-偏移动画
-调整抽奖顺序
