Unity第三人称移动

以下是一个简单的第三人称移动示例，包括人物的移动、转向和动画播放：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ThirdPersonMovement : MonoBehaviour
{
    public CharacterController controller;
    public Transform cam;
    public Animator animator;

    public float speed = 6f;
    public float turnSmoothTime = 0.1f;
    float turnSmoothVelocity;

    // Update is called once per frame
    void Update()
    {
        float horizontal = Input.GetAxisRaw("Horizontal");
        float vertical = Input.GetAxisRaw("Vertical");
        Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;

        if (direction.magnitude >= 0.1f)
        {
            float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;
            float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
            transform.rotation = Quaternion.Euler(0f, angle, 0f);

            Vector3 moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
            controller.Move(moveDir.normalized * speed * Time.deltaTime);

            animator.SetBool("isWalking", true);
        }
        else
        {
            animator.SetBool("isWalking", false);
        }
    }
}

其中，CharacterController是Unity提供的用于角色控制的组件，cam是摄像机的Transform组件，animator是角色的动画控制器。在Update函数中，首先获取水平和垂直方向上的输入值，然后计算出移动方向并进行平滑转向，最后移动角色并播放相应的动画。
