代码和预制体

函数PlayAnim（）中的角度要根据按钮数量手动填好

using System;
using DG.Tweening;
using DG.Tweening.Core;
using DG.Tweening.Plugins.Options;
using UnityEngine;// Token: 0x0200001B RID: 27

}

按钮根据数量计算角度排列均匀

using UnityEngine;
public class LookAtCamera : MonoBehaviour
{void Update(){transform.LookAt(transform.position + new Vector3(0,0,1));}
}
