Used by the editor to extend its functionality. Plugins are used by the editor to extend functionality. The most common types of plugins are those which edit a given node or resource type, import plugins and export plugins. See also [EditorScript] to add functions to the editor. https://docs.godotengine.org/en/latest/tutorials/plugins/editor/index.html Adds a script at [code]path[/code] to the Autoload list as [code]name[/code]. Adds a control to the bottom panel (together with Output, Debug, Animation, etc). Returns a reference to the button added. It's up to you to hide/show the button when needed. When your plugin is deactivated, make sure to remove your custom control with [method remove_control_from_bottom_panel] and free it with [method Node.queue_free]. Adds a custom control to a container (see [enum CustomControlContainer]). There are many locations where custom controls can be added in the editor UI. Please remember that you have to manage the visibility of your custom controls yourself (and likely hide it after adding it). When your plugin is deactivated, make sure to remove your custom control with [method remove_control_from_container] and free it with [method Node.queue_free]. Adds the control to a specific dock slot (see [enum DockSlot] for options). If the dock is repositioned and as long as the plugin is active, the editor will save the dock position on further sessions. When your plugin is deactivated, make sure to remove your custom control with [method remove_control_from_docks] and free it with [method Node.queue_free]. Adds a custom type, which will appear in the list of nodes or resources. An icon can be optionally passed. When given node or resource is selected, the base type will be instanced (e.g. "Node3D", "Control", "Resource"), then the script will be loaded and set to this object. You can use the virtual method [method handles] to check if your custom object is being edited by checking the script or using the [code]is[/code] keyword. During run-time, this will be a simple object with a script so this function does not need to be called then. Adds a [Script] as debugger plugin to the Debugger. The script must extend [EditorDebuggerPlugin]. Registers a new export plugin. Export plugins are used when the project is being exported. See [EditorExportPlugin] for more information. See [method add_inspector_plugin] for an example of how to register a plugin. Registers a new import plugin. Import plugins are used to add a new [Resource] which can be imported. See [EditorImportPlugin] for more information. [b]Note:[/b] If you want to import custom 3d files have a look at [method add_scene_import_plugin] instead. See [method add_inspector_plugin] for an example of how to register a plugin. Registers a new inspector plugin. Inspector plugins are used to extend the default inspector. See [EditorInspectorPlugin] for more information. [b]Note:[/b] Always use [method remove_inspector_plugin] to remove the [code]EditorInspectorPlugin[/code] if the [code]EditorPlugin[/code] is disabled. [codeblocks] [gdscript] const MyInspectorPlugin = preload("res://addons/your_addon/path/to/your/script.gd") var inspector_plugin = MyInspectorPlugin.new() func _enter_tree(): add_inspector_plugin(inspector_plugin) func _exit_tree(): remove_inspector_plugin(inspector_plugin) [/gdscript] [/codeblocks] Registers a new scene importer. Scene importers can import custom 3d formats as scenes. See [EditorImportPlugin] for more information. Registers a new gizmo plugin. Gizmo plugins are used to add custom gizmos to a [Node3D]. See [EditorNode3DGizmoPlugin] for more information. See [method add_inspector_plugin] for an example of how to register a plugin. Adds a custom menu item to [b]Project > Tools[/b] named [code]name[/code]. When clicked, the provided [code]callable[/code] will be called. Adds a custom submenu under [b]Project > Tools >[/b] [code]name[/code]. [code]submenu[/code] should be an object of class [PopupMenu]. Use [code]remove_tool_menu_item(name)[/code] on plugin clean up to remove the menu. Registers a custom translation parser plugin for extracting translatable strings from custom files. 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. This is used, for example, in shader editors to let the plugin know that it must apply the shader code being written by the user to the object. This method is called when the editor is about to run the project. The plugin can then perform required operations before the project runs. This method must return a boolean. If this method returns [code]false[/code], the project will not run. The run is aborted immediately, so this also prevents all other plugins' [method build] methods from running. 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. Called by the engine when the user disables the [EditorPlugin] in the Plugin tab of the project settings window. This function is used for plugins that edit specific object types (nodes or resources). It requests the editor to edit the given object. Called by the engine when the user enables the [EditorPlugin] in the Plugin tab of the project settings window. Called by the engine when the 2D editor's viewport is updated. Use the [code]overlay[/code] [Control] for drawing. You can update the viewport manually by calling [method update_overlays]. [codeblocks] [gdscript] func forward_canvas_draw_over_viewport(overlay): # Draw a circle at cursor position. overlay.draw_circle(overlay.get_local_mouse_position(), 64, Color.white) func forward_canvas_gui_input(event): if event is InputEventMouseMotion: # Redraw viewport when cursor is moved. update_overlays() return true return false [/gdscript] [csharp] public override void ForwardCanvasDrawOverViewport(Godot.Control overlay) { // Draw a circle at cursor position. overlay.DrawCircle(overlay.GetLocalMousePosition(), 64, Colors.White); } public override bool ForwardCanvasGuiInput(InputEvent @event) { if (@event is InputEventMouseMotion) { // Redraw viewport when cursor is moved. UpdateOverlays(); return true; } return false; [/csharp] [/codeblocks] This method is the same as [method forward_canvas_draw_over_viewport], except it draws on top of everything. Useful when you need an extra layer that shows over anything else. You need to enable calling of this method by using [method set_force_draw_over_forwarding_enabled]. Called when there is a root node in the current edited scene, [method handles] is implemented and an [InputEvent] happens in the 2D viewport. Intercepts the [InputEvent], if [code]return true[/code] [EditorPlugin] consumes the [code]event[/code], otherwise forwards [code]event[/code] to other Editor classes. Example: [codeblocks] [gdscript] # Prevents the InputEvent to reach other Editor classes func forward_canvas_gui_input(event): return true [/gdscript] [csharp] // Prevents the InputEvent to reach other Editor classes public override bool ForwardCanvasGuiInput(InputEvent @event) { return true; } [/csharp] [/codeblocks] Must [code]return false[/code] in order to forward the [InputEvent] to other Editor classes. Example: [codeblocks] [gdscript] # Consumes InputEventMouseMotion and forwards other InputEvent types. func forward_canvas_gui_input(event): return event is InputEventMouseMotion [/gdscript] [csharp] // Consumes InputEventMouseMotion and forwards other InputEvent types. public override bool ForwardCanvasGuiInput(InputEvent @event) { return @event is InputEventMouseMotion; } [/csharp] [/codeblocks] Called by the engine when the 3D editor's viewport is updated. Use the [code]overlay[/code] [Control] for drawing. You can update the viewport manually by calling [method update_overlays]. [codeblocks] [gdscript] func forward_spatial_draw_over_viewport(overlay): # Draw a circle at cursor position. overlay.draw_circle(overlay.get_local_mouse_position(), 64) func forward_spatial_gui_input(camera, event): if event is InputEventMouseMotion: # Redraw viewport when cursor is moved. update_overlays() return true return false [/gdscript] [csharp] public override void ForwardSpatialDrawOverViewport(Godot.Control overlay) { // Draw a circle at cursor position. overlay.DrawCircle(overlay.GetLocalMousePosition(), 64, Colors.White); } public override bool ForwardSpatialGuiInput(Godot.Camera3D camera, InputEvent @event) { if (@event is InputEventMouseMotion) { // Redraw viewport when cursor is moved. UpdateOverlays(); return true; } return false; [/csharp] [/codeblocks] This method is the same as [method forward_spatial_draw_over_viewport], except it draws on top of everything. Useful when you need an extra layer that shows over anything else. You need to enable calling of this method by using [method set_force_draw_over_forwarding_enabled]. Called when there is a root node in the current edited scene, [method handles] is implemented and an [InputEvent] happens in the 3D viewport. Intercepts the [InputEvent], if [code]return true[/code] [EditorPlugin] consumes the [code]event[/code], otherwise forwards [code]event[/code] to other Editor classes. Example: [codeblocks] [gdscript] # Prevents the InputEvent to reach other Editor classes. func forward_spatial_gui_input(camera, event): return true [/gdscript] [csharp] // Prevents the InputEvent to reach other Editor classes. public override bool ForwardSpatialGuiInput(Camera3D camera, InputEvent @event) { return true; } [/csharp] [/codeblocks] Must [code]return false[/code] in order to forward the [InputEvent] to other Editor classes. Example: [codeblocks] [gdscript] # Consumes InputEventMouseMotion and forwards other InputEvent types. func forward_spatial_gui_input(camera, event): return event is InputEventMouseMotion [/gdscript] [csharp] // Consumes InputEventMouseMotion and forwards other InputEvent types. public override bool ForwardSpatialGuiInput(Camera3D camera, InputEvent @event) { return @event is InputEventMouseMotion; } [/csharp] [/codeblocks] This is for editors that edit script-based objects. You can return a list of breakpoints in the format ([code]script:line[/code]), for example: [code]res://path_to_script.gd:25[/code]. Returns the [EditorInterface] object that gives you control over Godot editor's window and its functionalities. Override this method in your plugin to return a [Texture2D] in order to give it an icon. For main screen plugins, this appears at the top of the screen, to the right of the "2D", "3D", "Script", and "AssetLib" buttons. Ideally, the plugin icon should be white with a transparent background and 16x16 pixels in size. [codeblocks] [gdscript] func get_plugin_icon(): # You can use a custom icon: return preload("res://addons/my_plugin/my_plugin_icon.svg") # Or use a built-in icon: return get_editor_interface().get_base_control().get_icon("Node", "EditorIcons") [/gdscript] [csharp] public override Texture2D GetPluginIcon() { // You can use a custom icon: return ResourceLoader.Load<Texture2D>("res://addons/my_plugin/my_plugin_icon.svg"); // Or use a built-in icon: return GetEditorInterface().GetBaseControl().GetIcon("Node", "EditorIcons"); } [/csharp] [/codeblocks] Override this method in your plugin to provide the name of the plugin when displayed in the Godot editor. For main screen plugins, this appears at the top of the screen, to the right of the "2D", "3D", "Script", and "AssetLib" buttons. Gets the Editor's dialogue used for making scripts. [b]Note:[/b] Users can configure it before use. Gets the state of your plugin editor. 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). Gets the undo/redo object. Most actions in the editor can be undoable, so use this object to make sure this happens when it's worth it. Gets the GUI layout of the plugin. This is used to save the project's editor layout when [method queue_save_layout] is called or the editor layout was changed(For example changing the position of a dock). Implement this function if your plugin edits a specific type of object (Resource or Node). If you return [code]true[/code], then you will get the functions [method edit] and [method make_visible] called when the editor requests them. If you have declared the methods [method forward_canvas_gui_input] and [method forward_spatial_gui_input] these will be called too. Returns [code]true[/code] if this is a main screen editor plugin (it goes in the workspace selector together with [b]2D[/b], [b]3D[/b], [b]Script[/b] and [b]AssetLib[/b]). This function will be called when the editor is requested to become visible. It is used for plugins that edit a specific object type. Remember that you have to manage the visibility of all your editor controls manually. Queue save the project's editor layout. Removes an Autoload [code]name[/code] from the list. Removes the control from the bottom panel. You have to manually [method Node.queue_free] the control. Removes the control from the specified container. You have to manually [method Node.queue_free] the control. Removes the control from the dock. You have to manually [method Node.queue_free] the control. Removes a custom type added by [method add_custom_type]. Removes the debugger plugin with given script from the Debugger. Removes an export plugin registered by [method add_export_plugin]. Removes an import plugin registered by [method add_import_plugin]. Removes an inspector plugin registered by [method add_import_plugin] Removes a scene importer registered by [method add_scene_import_plugin]. Removes a gizmo plugin registered by [method add_spatial_gizmo_plugin]. Removes a menu [code]name[/code] from [b]Project > Tools[/b]. Removes a custom translation parser plugin registered by [method add_translation_parser_plugin]. 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. Enables calling of [method forward_canvas_force_draw_over_viewport] for the 2D editor and [method forward_spatial_force_draw_over_viewport] 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. Use this method if you always want to receive inputs from 3D view screen inside [method forward_spatial_gui_input]. It might be especially usable if your plugin will want to use raycast in the scene. Restore the state saved by [method get_state]. Restore the plugin GUI layout saved by [method get_window_layout]. Updates the overlays of the 2D and 3D editor viewport. Causes methods [method forward_canvas_draw_over_viewport], [method forward_canvas_force_draw_over_viewport], [method forward_spatial_draw_over_viewport] and [method forward_spatial_force_draw_over_viewport] to be called. Emitted when user changes the workspace ([b]2D[/b], [b]3D[/b], [b]Script[/b], [b]AssetLib[/b]). Also works with custom screens defined by plugins. Emitted when the scene is changed in the editor. The argument will return the root node of the scene that has just become active. If this scene is new and empty, the argument will be [code]null[/code]. Emitted when user closes a scene. The argument is file path to a closed scene. Represents the size of the [enum DockSlot] enum.
