		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.

	<methods>
		<method name="_apply_changes" qualifiers="virtual">
			<return type="void" />
			<description>
				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.
			</description>
		</method>
		<method name="_build" qualifiers="virtual">
			<return type="bool" />
			<description>
				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.
			</description>
		</method>
		<method name="_clear" qualifiers="virtual">
			<return type="void" />
			<description>
				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.
			</description>
		</method>
		<method name="_disable_plugin" qualifiers="virtual">
			<return type="void" />
			<description>
				Called by the engine when the user disables the [EditorPlugin] in the Plugin tab of the project settings window.
			</description>
		</method>
		<method name="_edit" qualifiers="virtual">
			<return type="void" />
			<argument index="0" name="object" type="Object" />
			<description>
				This function is used for plugins that edit specific object types (nodes or resources). It requests the editor to edit the given object.
			</description>
		</method>
		<method name="_enable_plugin" qualifiers="virtual">
			<return type="void" />
			<description>
				Called by the engine when the user enables the [EditorPlugin] in the Plugin tab of the project settings window.
			</description>
		</method>
		<method name="_forward_canvas_draw_over_viewport" qualifiers="virtual">
			<return type="void" />
			<argument index="0" name="overlay" type="Control" />
			<description>
				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)

			</description>
		</method>
		<method name="_forward_canvas_force_draw_over_viewport" qualifiers="virtual">
			<return type="void" />
			<argument index="0" name="overlay" type="Control" />
			<description>
				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].
			</description>
		</method>
		<method name="_forward_canvas_gui_input" qualifiers="virtual">
			<return type="bool" />
			<argument index="0" name="event" type="InputEvent" />
			<description>
				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:

				    return event is InputEventMouseMotion
				[/gdscript]

			<return type="void" />
			<argument index="0" name="overlay" type="Control" />

			<argument index="3" name="icon" type="Texture2D" />
			<description>
				Adds a custom type, which will appear in the list of nodes or resources. An icon can be optionally passed.
				When a given node or resource is selected, the base type will be instantiated (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.
