:::info 结合输入控制模块实现改建功能非常方便 :::

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class InputMgr : BaseManager<InputMgr>
{
    private bool isOpen = false;
    public InputMgr()
    {
        MonoMgr.GetInstance().AddUpdateListener(MyUpdate);
    }
    private void MyUpdate()
    {
        // 如果没开启检测则不检测
        if (!isOpen)
            return;
        CheckKeyCode(KeyCode.W);
        CheckKeyCode(KeyCode.S);
        CheckKeyCode(KeyCode.A);
        CheckKeyCode(KeyCode.D);
    }
    /// <summary>

    }
    // 控制输入检测的开关

例子

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class InputTest : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        // 开启输入检测
        InputMgr.GetInstance().StartOrEndCheck(true); 
        // 添加事件监听 [玩家死亡的时候只需要移除监听,就不会再检测]
        EventCenter.GetInstance().AddEventListener("某键按下", CheckInputDown);
        EventCenter.GetInstance().AddEventListener("某键抬起", CheckInputUp);
    }
    private void CheckInputDown(object key)
    {
        KeyCode keyCode = (KeyCode)key;
        switch(keyCode)
        {
            case KeyCode.W:
                Debug.Log("W_Down");
                break;
            case KeyCode.S:
                Debug.Log("S_Down");
                break;
            case KeyCode.A:
                Debug.Log("A_Down");
                break;
            case KeyCode.D:
                Debug.Log("D_Down");
                break;
        }
    }
    private void CheckInputUp(object key)
    {

            case KeyCode.W:
                Debug.Log("W_UP");
                break;
            case KeyCode.S:
                Debug.Log("S_UP");
                break;
            case KeyCode.A:
