_forwardCanvasForceDrawOverViewport(viewportControl:)for the 2D editor and_forward3dForceDrawOverViewport(viewportControl:)for the 3D editor when their viewports are updated. You need to call this method only once and it will work permanently for this plugin.func setInputEventForwardingAlwaysEnabled() Use this method if you always want to receive inputs from 3D view screen inside
_forward3dGuiInput(viewportCamera:event:). It might be especially usable if your plugin will want to use raycast in the scene.func updateOverlays() -> Int32 Updates the overlays of the 2D and 3D editor viewport. Causes methods
_forwardCanvasDrawOverViewport(viewportControl:),_forwardCanvasForceDrawOverViewport(viewportControl:),_forward3dDrawOverViewport(viewportControl:)and_forward3dForceDrawOverViewport(viewportControl:)to be called.

func _applyChanges() This method is called when the editor is about to save the project, switch to another tab, etc. It asks the plugin to apply any pending state changes to ensure consistency.
func _build() -> Bool This method is called when the editor is about to run the project. The plugin can then perform required operations before the project runs.
func _clear() Clear all the state and reset the object being edited to zero. This ensures your plugin does not keep editing a currently existing node, or a node from the wrong scene.
func _disablePlugin() Called by the engine when the user disables the
EditorPluginin the Plugin tab of the project settings window.func _edit(object: Object?) This function is used for plugins that edit specific object types (nodes or resources). It requests the editor to edit the given object.
func _enablePlugin() Called by the engine when the user enables the
EditorPluginin the Plugin tab of the project settings window.func _forward3dDrawOverViewport(viewportControl: Control?) Called by the engine when the 3D editor’s viewport is updated. Use the
overlayControlfor drawing. You can update the viewport manually by callingupdateOverlays.func _forward3dForceDrawOverViewport(viewportControl: Control?) This method is the same as
_forward3dDrawOverViewport(viewportControl:), except it draws on top of everything. Useful when you need an extra layer that shows over anything else.func _forward3dGuiInput(viewportCamera: Camera3D?, event: InputEvent?) -> Int32 Called when there is a root node in the current edited scene,
_handles(object:)is implemented, and anInputEventhappens in the 3D viewport. The return value decides whether theInputEventis consumed or forwarded to otherEditorPlugins. SeeAfterGUIInputfor options.func _forwardCanvasDrawOverViewport(viewportControl: Control?) Called by the engine when the 2D editor’s viewport is updated. Use the
overlayControlfor drawing. You can update the viewport manually by callingupdateOverlays.func _forwardCanvasForceDrawOverViewport(viewportControl: Control?) This method is the same as
_forwardCanvasDrawOverViewport(viewportControl:), except it draws on top of everything. Useful when you need an extra layer that shows over anything else.func _forwardCanvasGuiInput(event: InputEvent?) -> Bool Called when there is a root node in the current edited scene,
_handles(object:)is implemented and anInputEventhappens in the 2D viewport. Intercepts theInputEvent, ifreturn trueEditorPluginconsumes theevent, otherwise forwardseventto other Editor classes.func _getBreakpoints() -> PackedStringArray This is for editors that edit script-based objects. You can return a list of breakpoints in the format (
script:line), for example:res://path_to_script.gd:25.func _getPluginIcon() -> Texture2D? Override this method in your plugin to return a
Texture2Din order to give it an icon.func _getPluginName() -> String Override this method in your plugin to provide the name of the plugin when displayed in the Godot editor.
func _getState() -> GDictionary Override this method to provide a state data you want to be saved, like view position, grid settings, folding, etc. This is used when saving the scene (so state is kept when opening it again) and for switching tabs (so state can be restored when the tab returns). This data is automatically saved for each scene in an
editstatefile in the editor metadata folder. If you want to store global (scene-independent) editor data for your plugin, you can use_getWindowLayout(configuration:)instead.func _getUnsavedStatus(forScene: String) -> String Override this method to provide a custom message that lists unsaved changes. The editor will call this method when exiting or when closing a scene, and display the returned string in a confirmation dialog. Return empty string if the plugin has no unsaved changes.
func _getWindowLayout(configuration: ConfigFile?) Override this method to provide the GUI layout of the plugin or any other data you want to be stored. This is used to save the project’s editor layout when
queueSaveLayoutis called or the editor layout was changed (for example changing the position of a dock). The data is stored in theeditor_layout.cfgfile in the editor metadata directory.func _handles(object: Object?) -> Bool Implement this function if your plugin edits a specific type of object (Resource or Node). If you return
true, then you will get the functions_edit(object:)and_makeVisible(_:)called when the editor requests them. If you have declared the methods_forwardCanvasGuiInput(event:)and_forward3dGuiInput(viewportCamera:event:)these will be called too.func _hasMainScreen() -> Bool Returns
trueif this is a main screen editor plugin (it goes in the workspace selector together with 2D, 3D, Script and AssetLib).func _makeVisible(Bool) This function will be called when the editor is requested to become visible. It is used for plugins that edit a specific object type.
func _saveExternalData() This method is called after the editor saves the project or when it’s closed. It asks the plugin to save edited external scenes/resources.
func _setState(GDictionary) Restore the state saved by
_getState. This method is called when the current scene tab is changed in the editor.func _setWindowLayout(configuration: ConfigFile?) Restore the plugin GUI layout and data saved by
_getWindowLayout(configuration:). This method is called for every plugin on editor startup. Use the providedconfigurationfile to read your saved data.
