【问题描述】：

我正在开发某种寺庙运行游戏项目，只是为了教育目的。我创建了一个脚本，它应该从高处开始关注角色，然后将其位置更改为角色。就像在游戏脚本中当相机慢慢地向玩家倾斜时在寺庙奔跑中一样。这是我的脚本

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

public class CameraMotor : MonoBehaviour {
    private Vector3 ofset;
    private Vector3 characterposition;

    private float transition =0.0f;
    private float animationduration = 2.0f;
    private Vector3 animationoffset = new Vector3(0,2f,2f);
    void Start () {
        ofset = GameObject.FindObjectOfType<CharacterController> ().transform.position - this.transform.position;
    }

    // Update is called once per frame
    void Update () {
        characterposition = GameObject.FindObjectOfType<CharacterController> ().transform.position - ofset;
        characterposition.x = 1.3f;
        characterposition.y = Mathf.Clamp (characterposition.y, 3f, 5f);
        if (transition > 1.0f) {
            this.transform.position = characterposition;
        } else {
            this.transform.position = Vector3.Lerp (characterposition + animationoffset, characterposition, transition);
            transition =  Time.deltaTime* 1 / animationduration;
            this.transform.LookAt (characterposition, Vector3.up);
        }

    }
}

【解决方案1】：

下面的行是错误的

this.transform.LookAt (characterposition, Vector3.up);

LookAt() 方法需要 Transform 类型参数，而不是 Vector3。尝试使用这些

private Vector3 ofset;
private Vector3 characterposition;
private CharacterController characterCon;

private float transition =0.0f;
private float animationduration = 2.0f;
private Vector3 animationoffset = new Vector3(0,2f,2f);

void Start () {
    ofset = GameObject.FindObjectOfType<CharacterController> ().transform.position - this.transform.position;
    characterCon = GameObject.FindObjectOfType<CharacterController> ().GetComponent<CharacterController>();
}

void Update () {

    characterposition = characterCon.transform.position - ofset;
    characterposition.x = 1.3f;
    characterposition.y = Mathf.Clamp (characterposition.y, 3f, 5f);
    if (transition > 1.0f) {
        this.transform.position = characterposition;
    } else {
        this.transform.position = Vector3.Lerp (characterposition + animationoffset, characterposition, transition);
        transition =  Time.deltaTime * 1 / animationduration;
    }

    this.transform.LookAt (characterCon.transform, Vector3.up);
}

此外，您在每一帧调用 FindObjectOfType 方法都会导致性能不佳。看看下面的链接LookAt

【解决方案2】：

您已经很接近了，但您的转换值需要不断增加，您的 Lerp 才能正常工作。尝试更改此行：

transition =  Time.deltaTime* 1 / animationduration;

到

transition +=  Time.deltaTime* 1 / animationduration;
