Unity3D 摄像机第一人称稳定旋转移动

• 先创建一个C#脚本

直接上代码

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

public class Move : MonoBehaviour
{
    
    
    public Camera camera;
    public float Rotatespeed = 5;  //摄像机旋转速度
    // Start is called before the first frame update
    void Start()
    {
    
    
        
    }

    // Update is called once per frame
    void Update()
    {
    
    
        float moveSpeed = 1.5f;  //摄像机移动速度
        if (Input.GetKey(KeyCode.W))  //按W前进
        {
    
    
            transform.Translate(Vector3.forward * moveSpeed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.S))
        {
    
    
            transform.Translate(Vector3.back * moveSpeed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.A))
        {
    
    
            transform.Translate(Vector3.left * moveSpeed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.D))
        {
    
    
            transform.Translate(Vector3.right * moveSpeed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.Space))  //按空格，上升
        {
    
    
            transform.Translate(Vector3.up * moveSpeed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.LeftControl))
        {
    
    
            transform.Translate(Vector3.down * moveSpeed * Time.deltaTime);
        }
        float X = Input.GetAxis("Mouse X") * Rotatespeed;
        float Y = Input.GetAxis("Mouse Y") * Rotatespeed;
        camera.transform.localRotation = camera.transform.localRotation * Quaternion.Euler(-Y, 0, 0);
        transform.localRotation = transform.localRotation * Quaternion.Euler(0, X, 0);
        if (transform.localEulerAngles.z != 0)  //摄像机旋转Z轴锁定，如果没有这个，摄像机会左右上下旋转，不稳定
        {
    
    
            float rotX = transform.localEulerAngles.x;
            float rotY = transform.localEulerAngles.y;
            transform.localEulerAngles = new Vector3(rotX, rotY, 0);
        }
    }
}

• 将这个脚本挂载到摄像机上，便能使用
