C# 摧毁精确目标

我正在创建一个小2d游戏，你需要在其中生存。每棵树都有自己的强度=5。当玩家碰撞并按下鼠标左键时，力量值为-1，玩家木属性值为+1。当树的强度等于或小于0时，树将被破坏。这是我的密码：（问题在密码后面）

使用System.Collections.Generic；
使用UnityEngine；
使用UnityEngine.UI；

如果（treeLogStrenth那么为了澄清问题：
Stats
应该附加到玩家身上，对吗

您不应该在
Update
中的每一帧都做一些事情，而应该像

public class Stats : MonoBehaviour
{
    // You should never allow your stats to be set via public fields
    [SerializeField] private float hp = 100;
    [SerializeField] private float wood = 0;

    // if you need to read them from somewhere else you can use read-only properties
    public float HP => hp;
    public float Wood => wood;

    [SerializeField] private Text woodText;

    private void Start ()
    {
        woodText.text = "0";
    }

    public void AddWood(int amount)
    {
        wood += amount;
        woodText.text = wood.ToString();
    }
}

然后每个树应该有自己的组件实例，比如

public class Tree : MonoBehaviour
{
    [SerializeField] private float treeLogStrenth = 5;

    public void HandleClick(Stats playerStats)
    {
        // if this tree has wood left add it to the player stats
        if(treeLogStrength > 0)
        {
            playerStats.AddWood(1); 
            treeLogStrenth -= 1;
        }

        // destroy this tree when no wood left
        if (treeLogStrenth <= 0)
        {
            Destroy(gameObject);
        }
    }
}

公共类树：单行为
{
[SerializeField]专用浮点数treeLogStrenth=5；
公共无效HandleClick（统计玩家统计）
{
//如果这棵树还剩下木头，则将其添加到玩家统计数据中
如果（树形强度>0）
{
阿德伍德（1）；
treeLogStrenth-=1；
}
//在没有木头的时候把这棵树毁掉
如果（treeLogStrenth）这是JavaScript？-我删除了JavaScript标记，因为这是JAVA或已经标记的C.；
是不完整的代码你真的在使用Visual Studio 2010吗？！不管怎样，标签都是不需要的。我不明白你的问题。当你需要100棵树时，你必须创建100棵树才能摧毁它们。当然每棵树都有自己的碰撞器，所以你可以确定你碰撞了哪些树。@MaxCieplinski哪部分？等等这意味着每棵树都应该有自己的组件？如果有50个，那么代码就太多了trees@MaxCieplinski好吧，如果有50棵树，那么就有50个游戏对象带有
树
组件。是的，但是有没有办法不让每棵树都保持不变？@MaxCieplinski我不明白你的意思……如果每棵树都应该每个树都有自己的生命周期和可以接受的点击量，以便提供木材，那么没有…每个树都需要一个
树
组件的单独实例，以便处理与其相关的值。
