需要幫助夾緊相機旋轉

Question

我對編碼真的很陌生，並制作了這段代碼來圍繞播放器對象旋轉我的相機，但我不知道如何繼續鉗制 X 軸上的旋轉。

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

public class FollowPlayer : MonoBehaviour
{
    public float speed;
    public Transform target;

    // Start is called before the first frame update
    void Start()
    {
        
    }
    // Update is called once per frame
    void Update()
    {
        transform.RotateAround(target.position, transform.right, -Input.GetAxis("Mouse Y") * speed);
        transform.RotateAround(target.position, Vector3.up, -Input.GetAxis("Mouse X") * speed);
    }
}

這是我旋轉相機的代碼，我想夾住鼠標 Y。

這里的技巧是在進行轉換之前跟蹤累積的輸入並對其進行鉗制。 這比嘗試將相機的旋轉分解為正確的軸更容易且不易出錯。

public class FollowPlayer : MonoBehaviour
{
    public float speed;
    public Transform target;

    float vertical;
    float horizontal;
    Quaternion initalRotation;
    Vector3 initialOffset;

    // Start is called before the first frame update
    void Start()
    {
        initialRotation = transform.rotation;
        initialOffset = transform.position - target.position;
    }
    // Update is called once per frame
    void Update()
    {
        horizontal += - Input.GetAxis("Mouse X") * speed;
        vertical += - Input.GetAxis("Mouse Y") * speed;
        vertical = Mathf.Clamp(vertical, -20f, 20f);

        //always rotate from same origin
        transform.rotation = initialRotation;
        transform.position = target.position + initialOffset;
        transform.RotateAround(target.position, transform.right, vertical);
        transform.RotateAround(target.position, Vector3.up, horizontal);
    }
}
