Custom Value Drawer Attribute 特性，允许用户自定义一个绘制方法，字段将以自定的绘制方式展示在Inspector中，非常灵活。

含有Label和不含有Label的字段

    [CustomValueDrawer("HaveLabelNameFunction")]

    public string HaveLabelName;

    [CustomValueDrawer("NoLabelNameFunction")]

    public string NoLabelName;



    public string HaveLabelNameFunction(string tempName, GUIContent label)

    {

        return EditorGUILayout.TextField(tempName);

    }

    public string NoLabelNameFunction(string tempName, GUIContent label)

    {

        return EditorGUILayout.TextField(label,tempName);

    }

绘制Slider滑动条

    public float Max = 100, Min = 0;



    [CustomValueDrawer("MyStaticCustomDrawerStatic")]

    public float CustomDrawerStatic;

    private static float MyStaticCustomDrawerStatic(float value, GUIContent label)

    {

        return EditorGUILayout.Slider(label, value, 0f, 10f);

    }



    [CustomValueDrawer("MyStaticCustomDrawerInstance")]

    public float CustomDrawerInstance;



    private float MyStaticCustomDrawerInstance(float value, GUIContent label)

    {

        return EditorGUILayout.Slider(label, value, this.Min, this.Max);

    }



    [CustomValueDrawer("MyStaticCustomDrawerArray")]

    public float[] CustomDrawerArray = new float[] { 3f, 5f, 6f };





    private float MyStaticCustomDrawerArray(float value, GUIContent label)

    {

        return EditorGUILayout.Slider(value, this.Min, this.Max);

    }
