我怎样才能让相机从后面跟随玩家？

Question

using UnityEngine;
using System.Collections;

public class CameraController : MonoBehaviour
{

    public GameObject player;       //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 - player.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 = player.transform.position + offset;
        transform.LookAt(player.transform);
    }
}

如果我只使用这条线：

transform.LookAt(player.transform);

它会根据玩家的移动旋转摄像机，但摄像机会保持原位。当我也使用这条线时：

transform.position = player.transform.position + offset;

镜头会移动，但现在它会在玩家的前面，而不是跟随它的后面。我想让相机从后面看。

Answer 1

你应该在播放器本地获取偏移量space。您可以使用矢量数学（例如，player.transform.position - player.transform.forward * distance）或在玩家的层次结构中有一个引用空游戏对象作为相机的位置目标。

Answer 2

你的脚本是正确的；要让相机跟随玩家，您必须：

按照@apk 的建议，在层级视图中创建一个空的游戏对象并将其命名为"Player"、
将玩家和摄像机都添加到空游戏对象中。

创建空游戏对象时，不要忘记将其位置重置为 0, 0, 0。

希望对您有所帮助。

检查这个脚本，这将跟随带有相机永久注视矢量的目标，然后如果你想跟随目标的前向矢量需要向脚本添加额外的逻辑:)

public class CameraFollowController : MonoBehaviour
    {
        public GameObject target;
        int offsetDistance = 10;
        int offsetHeight = 5;
        Vector3 targetLookAtVec;

        void Start()
        {
            Camera.main.transform.position = target.transform.position 
                - target.transform.forward * offsetDistance
                + target.transform.up * offsetHeight;
            Camera.main.transform.LookAt(target.transform);
            targetLookAtVec = Camera.main.transform.position - target.transform.position;
        }
        void LateUpdate()
        {
            Camera.main.transform.position = target.transform.position + targetLookAtVec;
        }
    }
