1、安裝

window->package manager

2、創建Cinemachine

右鍵->Cinemachine->2D Carmera

3、創建空對象和多邊形控制器如圖

記得勾選 is Trigger

空對象位置記得要和小鳥保持一致，不然等下寫完腳本后，鏡頭一開始會移動一下

4、將多邊形觸發器拖拽到2d Camera中，如圖

5、給多邊形觸發器寫個腳本隨著小鳥鏡頭移動，不然小鳥會被擠出鏡頭

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class NewBehaviourScript : MonoBehaviour
{private GameObject player;// Start is called before the first frame updatevoid Start(){player = GameObject.Find("player");}// Update is called once per framevoid Update(){//水平跟隨玩家transform.position = new Vector3(player.transform.position.x, transform.position.y, transform.position.z);}
}

把腳本拖拽給多邊形觸發器
