"Unity3d" implements background processing in editor mode with inheriting Editorupdater class

The Ongui function of the Editorwindow class will only run when the window focus is on the editor window. If you want the focus not to be on the editor window, it can be updated in real time, and you can do the following:

OnDestroy	OnDestroy is called when the Editorwindow is closed.
onfocus	Called when the window gets keyboard focus.
Ongui	Implement your own editor GUI here.
Onhierarchychange	Called whenever the scene hierarchy has changed.
Oninspectorupdate	Oninspectorupdate is called at Ten frames per second to give the inspector a chance to update.
OnLostFocus	Called when the window loses keyboard focus.
Onprojectchange	Called whenever the project has changed.
Onselectionchange	Called whenever the selection has changed.
Update	Called multiple times per second on all visible windows.

However, if the editor window is pasted onto a large window, it selects the window with its peers, thus hiding the editor window so that the Ongui function cannot be called. Therefore, in order to achieve more efficient background processing, we can inherit a editorupdate class that we write.

usingSystem;usingSystem.Collections;usingSystem.Reflection;usingUnityeditor;usingUnityengine; [Initializeonload] Public classEditormonobehaviour {StaticEditormonobehaviour () {varType = Types.gettype ("unityeditor.editorassemblies","UnityEditor.dll"); varmethod = Type. GetMethod ("subclassesof", bindingflags.static| bindingflags.nonpublic| BindingFlags.Instance,NULL,Newtype[]{typeof(Type)},NULL); varE = method. Invoke (NULL,New Object[] {typeof(Editormonobehaviour)}) asIEnumerable; foreach(Type Editormonobehaviourclassinche) {method= EditorMonoBehaviourClass.BaseType.GetMethod ("Oneditormonobehaviour", BindingFlags.NonPublic |bindingflags.instance); if(Method! =NULL) {method. Invoke (System.Activator.CreateInstance (editormonobehaviourclass),New Object[0]); }        }    }    Private voidOneditormonobehaviour () {editorapplication.update+=Update; Editorapplication.hierarchywindowchanged+=onhierarchywindowchanged; Editorapplication.hierarchywindowitemongui+=Hierarchywindowitemongui; Editorapplication.projectwindowchanged+=onprojectwindowchanged; Editorapplication.projectwindowitemongui+=Projectwindowitemongui; Editorapplication.modifierkeyschanged+=onmodifierkeyschanged; editorapplication.callbackfunction function= () + =Onglobaleventhandler (event.current); FieldInfo Info=typeof(editorapplication). GetField ("Globaleventhandler", BindingFlags.Static | BindingFlags.Instance |bindingflags.nonpublic); Editorapplication.callbackfunction functions= (editorapplication.callbackfunction) info. GetValue (NULL); function+=function; Info. SetValue (NULL, (Object) functions); Editorapplication.searchchanged+=onsearchchanged; Editorapplication.playmodestatechanged+ = () = {            if(editorapplication.ispaused) {onplaymodestatechanged (playmodestate.paused); }                if(editorapplication.isplaying) {onplaymodestatechanged (playmodestate.playing); }            if(Editorapplication.isplayingorwillchangeplaymode) {onplaymodestatechanged (Playmodestate.pla            Yingorwillchangeplaymode);        }        };    Start (); }     Public Virtual voidStart () {} Public Virtual voidUpdate () {} Public Virtual voidonhierarchywindowchanged () {} Public Virtual voidHierarchywindowitemongui (intinstanceid,rect Selectionrect) {}     Public Virtual voidonprojectwindowchanged () {} Public Virtual voidProjectwindowitemongui (stringguid,rect Selectionrect) {}     Public Virtual voidonmodifierkeyschanged () {} Public Virtual voidOnglobaleventhandler (Event e) {} Public Virtual voidonsearchchanged () {} Public Virtual voidonplaymodestatechanged (Playmodestate playmodestate) {} Public enumplaymodestate {Playing, Paused, Stop, Playingorwillchangeplaymode}}

This class is then inherited in another script, and methods such as start and update are overloaded, and the background logic in these methods can be updated in the background.

using Unityengine; using System.Collections;  Public class updatertest:editormonobehaviour{    publicoverridevoid  Update ()    {            }}
