项目需求：要近距离观察上图的圆柱
解决核心：把摄像机移动到，圆柱前方，离圆柱z坐标5个单位的地方。
参考代码：此处移动用的是DOTween插件的“DOLocalMove（目标位置，耗费时间）；”方法。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using DG.Tweening;
public class TestCameraMove : MonoBehaviour
{
private Vector3 cameraOriginPos = new Vector3(0,1,-10);
public Transform targetTra;
//private Vector3 aimPos = targetGOPos - new Vector3();
public bool flag;
void Awake()
{
}
void Start()
{
}
void Update()
{
}
public void MoveCamera()
{
Vector3 aimPos = targetTra.localPosition - new Vector3(0,0,5);
if (!flag)
{
Camera.main.transform.DOLocalMove(aimPos,2);
flag = true;
}
else
{
Camera.main.transform.DOLocalMove(cameraOriginPos,2);
flag = false;
}
}
}
实现效果：
