關卡按鈕代碼

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class LevelButton : MonoBehaviour
{private LevelSelector levelSelector;[SerializeField]  private Button levelButton;public void RegisterLevelSelector(LevelSelector levelSelector){this.levelSelector = levelSelector;levelButton.onClick.AddListener(() =>{levelSelector.MoveLevelToBottom(int.Parse(gameObject.name));});}}

配置

如果關卡按鈕被背景遮住

給添加canvas組件，Overrider Sorting 打開 sort order 為-1
