### 编写脚本`ThirdCharacterController.cs`
- 修改`Assets\Scripts\StudyCase2` 下脚本 `ThirdCharacterController.cs`  
```csharp
using UnityEngine;
using UnityEngine.InputSystem;

namespace StudyCase2
{
    public class ThirdCharacterController : MonoBehaviour
    {
        CharacterController characterController;
        InputActionAsset inputAction;
        Animator animator;
        Transform forward;
        Transform model;
        Cinemachine.CinemachineVirtualCamera vCam;
        public float moveSpeed = 5f;
        public float jumpSpeed = 2f;
        public float turnSpeed = 10f;
        public float gravity = 10f;
        Vector3 moveDir;
        Vector2 moveInput;
        private void Awake()
        {
            characterController = GetComponent<CharacterController>();
            forward = transform.Find("Forward");
            model = transform.Find("Model");
            animator = model.GetComponentInChildren<Animator>();
            vCam = transform.Find("Virtual Camera").GetComponent<Cinemachine.CinemachineVirtualCamera>();
            inputAction = Resources.Load<InputActionAsset>("PlayerInputActions");
            inputAction.FindAction("Move").started += OnMove;
            inputAction.FindAction("Move").performed += OnMove;
            inputAction.FindAction("Move").canceled += OnMove;
            inputAction.FindAction("Jump").performed += OnJump;
            inputAction.Enable();
        }
        private void Update()
        {
            moveDir = new Vector3(moveInput.x, moveDir.y, moveInput.y);
            forward.eulerAngles = new Vector3(0, vCam.transform.eulerAngles.y, 0);
            moveDir = forward.TransformDirection(moveDir);
            if (moveInput != Vector2.zero)
            {
                animator.SetBool("Move", true);
                Quaternion target = Quaternion.LookRotation(new Vector3(moveDir.x, 0, moveDir.z));
                model.rotation = Quaternion.Slerp(model.rotation, target, turnSpeed * Time.deltaTime);
            }
            else animator.SetBool("Move", false);
            if (!characterController.isGrounded)
                moveDir.y -= gravity * Time.deltaTime;
            characterController.Move(moveDir * moveSpeed * Time.deltaTime);
        }
        public void OnMove(InputAction.CallbackContext context)
        {
            if (characterController.isGrounded)
                moveInput = context.ReadValue<Vector2>();
            else moveInput = Vector2.zero;
        }
        public void OnJump(InputAction.CallbackContext context)
        {
            if (characterController.isGrounded)
            {
                moveDir.y = jumpSpeed;
            }
        }
    }
}
```
### 代码讲解
在Awake中自动获取组件，移除PlayerInput
```csharp
private void Awake()
{
    characterController = GetComponent<CharacterController>();
    forward = transform.Find("Forward");
    model = transform.Find("Model");
    animator = model.GetComponentInChildren<Animator>();
    vCam = transform.Find("Virtual Camera").GetComponent<Cinemachine.CinemachineVirtualCamera>();
    inputAction = Resources.Load<InputActionAsset>("PlayerInputActions");
    inputAction.FindAction("Move").started += OnMove;
    inputAction.FindAction("Move").performed += OnMove;
    inputAction.FindAction("Move").canceled += OnMove;
    inputAction.FindAction("Jump").performed += OnJump;
    inputAction.Enable();
}
```
```csharp
    //设置动画控制器参数
    //true：播放Moveing动画
    //false：播放Move end动画，然后回到Idle
    animator.SetBool("Move", true);
```
### Player节点设置  
挂载studycase2的控制器，移除PlayerInput组件

## 6.异闻录-FAQ
- **代码查找组件报错**：确认获取物体的名字和物体实际名字一致。
- **代码加载InputActionAsset报错**：确认处于`Resources`文件夹下，名字和查找名字一致。
- **移动不播放动画**：确认动画控制器的参数名字和脚本中设置的一样。
- **动画只播放一遍**：检查是否勾选循环播放，在模型上看。
- **动画状态切换有延迟**：确认动画控制器中连接线的`HasExitTime`是否勾选。

完成以上步骤，即可得到一个带动画的第三人称控制器。[项目地址](http://home.gtuantuan.online:8300/TuanTuan/StudyCase)
