U3D里面用程序出现错误！

MissingComponentException: There is no 'CharacterController' attached to the "SusaYukio" game object, but a script is trying to access it.
You probably need to add a CharacterController to the game object "SusaYukio". Or your script needs to check if the component is attached before using it.
UnityEngine.CharacterController.Move (Vector3 motion) (at C:/BuildAgent/work/d3d49558e4d408f4/artifacts/EditorGenerated/NewDynamics.cs:2775)
FPSWalker_edit02.FixedUpdate () (at Assets/SusaYukio/FPSWalker_edit02.cs:44)
我从网上下了个C#脚本放到角色里发现出错了，这个提示是啥意思啊···运行不起来哦！

添加一个人物控制器。。。。
