C# 我如何让用户选择摄像机是否在播放器后面？

这是使相机跟随播放器的原始代码：

using UnityEngine;
using System.Collections;

public class CameraFollow : MonoBehaviour
{
    public GameObject objectToFollow;       //Public variable to store a reference to the player game object
    private Vector3 offset;         //Private variable to store the offset distance between the player and camera

    // Use this for initialization
    void Start()
    {
        //Calculate and store the offset value by getting the distance between the player's position and camera's position.
        offset = transform.position - objectToFollow.transform.position;
    }

    // LateUpdate is called after Update each frame
    void LateUpdate()
    {
        // Set the position of the camera's transform to be the same as the player's, but offset by the calculated offset distance.
        transform.position = objectToFollow.transform.position + offset;
        transform.LookAt(objectToFollow.transform);
    }
}

这就是我试图做的，但是玩家自己（第三个人控制者）并没有根据他移动的方向旋转

根据上面的原始脚本，他做到了

using UnityEngine;
using System.Collections;

public class CameraFollow : MonoBehaviour
{
    public GameObject objectToFollow;       //Public variable to store a reference to the player game object
    public bool behindPlayer = false;

    private Vector3 cameraStartPos;

    // Use this for initialization
    void Start()
    {
        cameraStartPos = transform.position;

        // Put the camera behind the player
        if (behindPlayer == true)
        {
            transform.position = (objectToFollow.transform.position - (objectToFollow.transform.forward * 5) + (objectToFollow.transform.up * 2));
        }
    }

    private void Update()
    {
        if (behindPlayer == true)
        {
            transform.position = (objectToFollow.transform.position - (objectToFollow.transform.forward * 5) + (objectToFollow.transform.up * 2));
        }
        else
        {
            transform.position = cameraStartPos;
        }
    }

    // LateUpdate is called after Update each frame
    void LateUpdate()
    {
        transform.position = objectToFollow.transform.position;
        transform.LookAt(objectToFollow.transform);
    }
}

我想，相机将自动背后的球员已经没有必要改变相机的位置，如果用户想使用bool变量

但现在的脚本与上面的不同：

使用最新更新中的此行：

transform.position = objectToFollow.transform.position;

使用bool false/true，根本不会改变摄像机的位置。 没有这条线，玩家将移动，相机将跟随，但玩家不会旋转，也不会像上面那样移动

我想要的与第一个脚本一样，但带有behindPlayer变量。

工作脚本：

using UnityEngine;
using System.Collections;

public class CameraFollow : MonoBehaviour
{
    [SerializeField]
    private Transform target;

    [SerializeField]
    private Vector3 offsetPosition;

    [SerializeField]
    private Space offsetPositionSpace = Space.Self;

    [SerializeField]
    private bool lookAt = true;

    private void Update()
    {
        Refresh();
    }

    public void Refresh()
    {
        if (target == null)
        {
            Debug.LogWarning("Missing target ref !", this);

            return;
        }

        // compute position
        if (offsetPositionSpace == Space.Self)
        {
            transform.position = target.TransformPoint(offsetPosition);
        }
        else
        {
            transform.position = target.position + offsetPosition;
        }

        // compute rotation
        if (lookAt)
        {
            transform.LookAt(target);
        }
        else
        {
            transform.rotation = target.rotation;
        }
    }
}

在inspector中，例如将偏移设置为0,5，-12，并将其设置为目标设置，例如ThirdPersonController。并将脚本附加到摄影机（如果目标是ThirdPersonController，则必须将摄影机标记为Main Camera，因为ThirdPersonController ThirdPersonUserControl脚本正在查找主摄影机）

摄像机不必是目标的子对象，摄像机可以位于层次结构中的任何位置

不管怎么说，它起作用了
