Unity扩展让枚举视图中变成多选框

标签：

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;}
