Unity扩展让枚举视图中变成多选框

如图:

定义属性描述特性(因为没有描述的数据,让绘制类去绘制所以为空)

using UnityEngine;
using System.Collections;


public class EnumFlagsAttribute : PropertyAttribute {}

自定义属性绘制类:

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomPropertyDrawer(typeof(EnumFlagsAttribute))]
public class EnumFlagsAttributeDrawer : PropertyDrawer {
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        /*
         * 绘制多值枚举选择框,0 全部不选, -1 全部选中, 其他是枚举之和
         * 枚举值 = 当前下标值 ^ 2
         * 默认[0^2 = 1 , 1 ^2 = 2,  4, 16 , .....]
         */
        property.intValue = EditorGUI.MaskField(position, label, property.intValue
                                                , property.enumNames);

        Debug.Log("图层的值:" + property.intValue);

    }
}

组件:

using UnityEngine;
using System.Collections;


public enum LayerMeskEnum 
{
    Layer1,
    Layer2,
    Layer3,
    Layer4,
}

public class MyCompoment : MonoBehaviour {

    [EnumFlagsAttribute]
    public LayerMeskEnum layer;
}
