  30. Currently, I am trying to set up a simple script where an enemy will move towards and rotate towards the player. The rotation &amp; running animations play just fine, but the enemy that is supposed to move is stuck in place.
  32. I have tried Debugging it with logs as well as baking the navmesh, the issue could have somthing to do with velocity but I&#39;m just not sure. Thanks for reading this.
  34. Here is the Code as well as the inspector:

  4. **得分**: 0
  5. 记住，在 OnAnimatorMove() 正常工作的前提下，Unity 编辑器中的 Animator 组件的 Apply Root Motion 复选框应该被勾选。
  6. <details>
  7. <summary>英文:</summary>
  8. Remember that for the OnAnimatorMove() to work correctly, the Animator component&#39;s Apply Root Motion checkbox should be checked in the Unity editor.
