ToggleGroup用于任何字段，并創(chuàng)建一組可切換的選項。使用此選項可以創(chuàng)建可以啟用或禁用的選項。

【ToggleGroup】 通過制定一個返回bool值得成員名來控制toggle的開關(guān) ，默認以成員的名稱作為標題顯示

注意：此bool 成員不能為static

    [ToggleGroup("MyToggle")]
    public bool MyToggle;

    [ToggleGroup("MyToggle")]
    public float A;

    [ToggleGroup("MyToggle")]
    [HideLabel, Multiline]
    public string B;

也可以以制定toggle group的標題，或者通過$特殊標識符引用一個成員的值作為標題

    [ToggleGroup("EnableGroupOne", "$GroupOneTitle")]
    public bool EnableGroupOne = true;

    [ToggleGroup("EnableGroupOne")]
    public string GroupOneTitle = "One";

    [ToggleGroup("EnableGroupOne")]
    public float GroupOneA;

    [ToggleGroup("EnableGroupOne")]
    public float GroupOneB;

如果制定的toggle為class結(jié)構(gòu)，需要添加Serializable特性，toggle標題默認為此類的名稱，且繼承關(guān)系的父類結(jié)構(gòu)同樣可以繪制在檢查器面板上

    [Toggle("Enabled")]
    public MyToggleObject Three = new MyToggleObject();

    [Toggle("Enabled")]
    public MyToggleA Four = new MyToggleA();

    [Toggle("Enabled")]
    public MyToggleB Five = new MyToggleB();

    [Serializable]
    public class MyToggleObject
    {
        public  bool Enabled;

        [HideInInspector]
        public string Title;

        public int A;
        public int B;
    }

    [Serializable]
    public class MyToggleA : MyToggleObject
    {
        public float C;
        public float D;
        public float F;
    }

    [Serializable]
    public class MyToggleB : MyToggleObject
    {
        public string Text;
    }
