Unity extension makes the enum view a multi-marquee

:

Define attribute Description attributes (because no data is described, so that the drawing class is drawn so that it is empty)

using Unityengine; using System.Collections;  Public class Enumflagsattribute:propertyattribute {}

Custom Attribute Drawing class:

usingUnityengine;usingSystem.Collections;usingUnityeditor; [Custompropertydrawer (typeof(Enumflagsattribute))] Public classEnumflagsattributedrawer:propertydrawer { Public Override voidOngui (Rect position, Serializedproperty property, Guicontent label) {/** Draw Multi-Value enumeration selection box, 0 all unselected, 1 all selected, others are enumerated and * enumeration value = Current Subscript value ^ 2 * default [0^2 = 1, 1 ^2 = 2, 4, 16, ....         .] */Property.intvalue=Editorgui.maskfield (position, label, Property.intvalue, Property.enum        Names); Debug.Log ("the value of the layer:"+property.intvalue); }}

Component:

using Unityengine; using System.Collections;  Public enum Layermeskenum {    Layer1,    Layer2,    Layer3,    Layer4,}publicclass mycompoment:monobehaviour {    [enumflagsattribute]    public  layermeskenum layer;}
