Button Attribute特性：用于为一个方法在检查器中绘制一个触发该方法的功能按钮

【Button】在检查器上绘制哥哥按钮，如果含有参数，默认以折页的方式展示

    [Button]
    private void Default()
    {
    }
    [Button]
    private void Default(float a, float b, GameObject c)
    {
    }

    [Button]
    private void Default(float t, float b, float[] c)
    {
    }

以为为这个button指定一个名称，而且也可以通过特殊字符$引用一个字段作为名称

    public string ButtonName = "Dynamic button name";

    public bool Toggle;

    [Button("$ButtonName")]
    private void DefaultSizedButton()
    {
        this.Toggle = !this.Toggle;
    }

可以通过特殊字符@ 写入方法体调用

    [Button("@\"Expression label: \" + DateTime.Now.ToString(\"HH:mm:ss\")")]
    public void ExpressionLabel()
    {
        this.Toggle = !this.Toggle;
    }

【ButtonSizes】指定不同尺寸的按钮

    [Button(ButtonSizes.Small), GUIColor(0.3f, 0.8f, 1)]
    private void SmallButton()
    {
        this.Toggle = !this.Toggle;
    }

    [Button(ButtonSizes.Medium), GUIColor(0.4f, 0.4f, 1)]
    private void MediumSizedButton()
    {
        this.Toggle = !this.Toggle;
    }

    [Button(ButtonSizes.Large), GUIColor(0.5f, 0.8f, 0.5f)]
    private void LargeButton()
    {
        this.Toggle = !this.Toggle;
    }

    [Button(ButtonSizes.Gigantic),GUIColor(0.6f, 0.8f, 0)]
    private void GiganticButton()
    {
        this.Toggle = !this.Toggle;
    }

也是自定义尺寸

    [Button(90)]
    private void CustomSizedButton()
    {
        this.Toggle = !this.Toggle;
    }

【ButtonStyle】指定展示样式

    [Button(ButtonSizes.Medium, ButtonStyle.FoldoutButton)]
    private int FoldoutButton(int a = 2, int b = 2)
    {
        return a + b;
    }

    [Button(ButtonSizes.Medium, ButtonStyle.FoldoutButton)]
    private void FoldoutButton(int a, int b, ref int result)
    {
        result = a + b;
    }

    [Button(ButtonSizes.Large, ButtonStyle.Box)]
    private void Box(float a, float b, out float c)
    {
        c = a + b;
    }

    [Button(ButtonSizes.Large, ButtonStyle.Box)]
    private void Box(int a, float b, out float c)
    {
        c = a + b;
    }
    [Button(ButtonSizes.Large, ButtonStyle.CompactBox)]
    public void CompactBox(int a, float b, out float c)
    {
        c = a + b;
    }

【Expanded】如果有参数的控制是否强制展开折页（去除折页方式）

    [Button(ButtonStyle.CompactBox, Expanded = true)]
    private void CompactExpanded(float a, float b, GameObject c)
    {
    }

    [Button(ButtonSizes.Medium, ButtonStyle.Box, Expanded = true)]
    private void FullExpanded(float a, float b)
    {
    }
