在脚本的顶部，我添加了变量_birdscount：
public int _birdscount;
然后在LoadSettings函数中添加了以下行：
res.boidSettings [0].BirdsCount = _birdscount;
所以每次我在Inspector的编辑器中更改_birdscount的值然后运行游戏它都会生效。
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;
}
但是现在我想在游戏运行的时候，如果我在Inspector中更改_birdscount的值它也会生效。
所以我尝试在Update功能中执行此操作，如果您单击/按下按钮e它将在游戏运行时进行更改，但它不会实时更改鸟类数量。所以我猜是刚刚打电话：
LoadSettings ();
Restart ();
不够或不对。
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();
}
