Unity 3DCheck if int is met and do something？

Question

在我的游戏中，玩家可以拾取树叶、石头和原木。我想给玩家添加条件，当某个拾取等于 5 时，玩家将激活。

播放器由5个模块组成，每个模块在拾取东西时都会被替换为一个拾取器。这意味着玩家可以由 5 片树叶、5 块石头或 5 根原木或这些物品的组合组成。

[Header("Real-Time Statistics")]
public int numberOfLeaves;
public int numberOfLogs;
public int numberOfRocks;

这方面显示在检查器中，并在玩家找到拾取物时更新。

void OnTriggerStay2D(Collider2D other){
        if(Input.GetKeyDown(KeyCode.P)){

            if(other.gameObject.tag == "Leaf"){
                Pickup(1); // 1 = leaf, according to the ModuleStateAndTextureController script.
                numberOfLeaves += 1;
                Destroy(other.gameObject); // destroy the pickup item as we are picking it up
            }
            if(other.gameObject.tag == "WoodLog"){
                Pickup(2); // 2 = wood log, according to the ModuleStateAndTextureController script.
                numberOfLogs += 1;
                Destroy(other.gameObject); // destroy the pickup item as we are picking it up
           }
            if(other.gameObject.tag == "Rock"){
                Pickup(3); // 3 = rock, according to the ModuleStateAndTextureController script.
                numberOfRocks += 1;
                Destroy(other.gameObject); // destroy the pickup item as we are picking it up
            }

        }
    }

这部分脚本会在找到某个拾取器时向 int 添加一个数字。当玩家掉落拾取物时，我在脚本中有类似的部分。

我将如何编写一个脚本来检查玩家是否满足特定条件，即如果玩家由 5 片树叶组成，他将能够跳得更高，下降得更慢？

我的想法是这样的：如果播放器由 5 个树叶 jumpPower = 2000; 或类似的东西组成。我猜这将是添加到玩家对象中的特征，但我还需要知道如何在其他对象上使用这些 int，即可以检查玩家是否由 3 片树叶和 2 根木头组成的触发器。

我希望有人能帮助我设置它，因为我作为设计师很难编写脚本。

如果您充分理解您的需求，这是您可以使用的简单示例。您可以将委托与属性结合使用，以便在设置变量值时使事情发生。

public Class MyClass : MonoBehaviour {


    // Delegates, like a pointer in C, but to method(s) instead of variable
        public delegate void valueLogsChangedDelegate (int valueLogs);
        public valueLogsChanged valueLogsChanged = delegate { };


    private int _numberOfLogs;

// Property, when you set numberOfLogs (eg numberOfLogs = 10), every thing in "set" is executed
    public int numberOfLogs {
        get {
            return _numberOflogs;
        }
        set {
            _numberOfLogs = value;
            valueLogsChanged(_numberOflogs);
        }

    }

  /// <summary>
  /// Awake is called when the script instance is being loaded.
  /// </summary>
  void Awake()
  {
      // Subscribe to the delegate, you can add as many methods as you want. Every methods that subscribe to the delegate will be excuted when the delegate is called
      valueLogsChanged += Method;
  }

  void Method(int valueLogs)
  {
      if (valueLogs > 5)
      {
          jumpPower = 2000;
      }
  }

}

我累了，所以我可能犯了一个错误。另外，如有不明白您的需求，请见谅！
