C# 在游戏运行时，如何检查变量值是否更改？

c# unity3d

C# 在游戏运行时，如何检查变量值是否更改？,c#,unity3d,C#,Unity3d,在脚本的顶部，我添加了变量_birdscont： public int _birdscount; 然后在LoadSettings函数中，我添加了以下行： res.boidSettings [0].BirdsCount = _birdscount; 因此，每次我在Inspector的编辑器中更改_birdscont的值，然后运行游戏时，它就会生效 Settings LoadSettings() { TextAsset temp = (TextAsset)Resources.Load

在脚本的顶部，我添加了变量_birdscont：

public int _birdscount;

然后在LoadSettings函数中，我添加了以下行：

res.boidSettings [0].BirdsCount = _birdscount;

因此，每次我在Inspector的编辑器中更改_birdscont的值，然后运行游戏时，它就会生效

Settings LoadSettings()
  {
    TextAsset temp = (TextAsset)Resources.Load(SettingsFileName);
    var str = new StringReader(temp.text);
    Resources.UnloadAsset(temp);
    res = (Settings)serializer.Deserialize(str);

    while( res.boidSettings.Count < instancePoints.Length )
      res.boidSettings.Add(new BoidSettingsEx());
        res.boidSettings [0].BirdsCount = _birdscount;
    return res;
  }

这是不够的或是不对的

void Update()
  {
        if (Input.GetKeyDown ("space")) 
            OnSettingsClick ();

        if (Input.GetKeyDown ("e")) 
        {
            LoadSettings ();
            Restart ();
        }

    //We call it here to be sure that click on button desn't lead to camera target changing
    if( !guiTools.MouseOverGUI && Input.GetMouseButtonDown(0) )
      cameraControl.CheckForNewTarget( Input.mousePosition );

    guiTools.ManualUpdate();
