【Unity】使用Cinemachine+CharacterController实现第三人称视角下的角色视角、移动和跳跃控制

ai 2025/7/27 18:51:04

1.初始配置

安装Cinemachine插件
给角色添加CharacterConroller
创建Cinemachine-->Free Look Camera
在Free Look Camera中调整参数，Y Axis勾选Inver，X Axis取消勾选Inver
Free Look Camera要看向角色 + 跟随角色（自行设置，我就不再赘述了）

2.编写C#脚本

代码可以自行收藏直接用，关键自行调整的参数是：

speed、rotateSpeed、jumpHeight

using UnityEngine;public class PlayerController : MonoBehaviour
{[Header("参数")] public float speed; //角色移动速度（跑步的时候是两倍）public float rotateSpeed; //角色转向速度public float playerGravity = 9.8F; //角色重力public float jumpForce; //跳跃力度public float jumpHeight = 2F; //跳跃高度public float verticalVelocity = 0;//垂直速度[Header("状态")] public bool isMove; //是否在移动public bool isRun; //是否在跑步[Header("输入")]public Vector3 inputDirection; //wasd输入（x值表示horizontal，z值表示vertical，y值为0）[Header("组件")]public CharacterController characterController; //这个在Start函数中初始化，你也可以在Inspector初始化private void Start(){inputDirection = new Vector3();characterController = GetComponent<CharacterController>();}private void Update(){//计算WASD输入inputDirection.x = Input.GetAxisRaw("Horizontal");inputDirection.z = Input.GetAxisRaw("Vertical");//获得是否是移动和跑步状态isMove = inputDirection.magnitude > 0;isRun = isMove && Input.GetKey(KeyCode.LeftShift);//光标的可见性设置if (Input.GetKeyDown(KeyCode.I)){Cursor.visible = !Cursor.visible;}if (Input.GetKeyDown(KeyCode.Space)){characterController.SimpleMove(transform.up * jumpForce);}if (!isMove) return;//实现角色转向到相机平行于xz轴构成的平面的朝向Vector3 targetDirection = new Vector3(inputDirection.x, 0, inputDirection.z);float y = Camera.main.transform.rotation.eulerAngles.y;Quaternion targetRotation = Quaternion.Euler(0, y, 0) * Quaternion.LookRotation(targetDirection);// 使用Quaternion.Slerp进行平滑转向transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * rotateSpeed);}private void FixedUpdate(){Vector3 moveDirection = Vector3.zero;moveDirection += transform.forward * inputDirection.z;moveDirection += transform.right * inputDirection.x;moveDirection *= Time.fixedDeltaTime * (isRun ? speed*2 : speed);// 重力if (!characterController.isGrounded)verticalVelocity -= playerGravity * Time.fixedDeltaTime;// a*t=velseverticalVelocity = 0.0F;// 跳跃if (Input.GetButton("Jump")){// 得在地面才能跳if (characterController.isGrounded){verticalVelocity = Mathf.Sqrt(jumpHeight * 2 / playerGravity) * playerGravity;// 初始向上速度}}moveDirection.y += verticalVelocity * Time.fixedDeltaTime;// v*t=s// 移动characterController.Move(moveDirection);}
}
