Godot Engine：编辑器插件（Editor Plugin）开发 之 添加一个编辑器按钮

新建按钮

编辑器按钮的创建方式和普通按钮完全一致

按钮的脚本，注意一定要加上 tool，这样才可以在编辑器中执行

tool
extends Button

func _enter_tree():
	connect("pressed",self,"_on_btn_click")
	
func _exit_tree():
	disconnect("pressed",self,"_on_btn_click")

func _on_btn_click():
	print("do something...")

EditorPlugin脚本

tool
extends EditorPlugin


var loader_ui

func _enter_tree():
	print("GridPawnLoader Plugin Activated")
	add_addon()

func _exit_tree():
	print("GridPawnLoader Plugin Deactivated")
	remove_addon()

func add_addon():
	loader_ui = preload("res://addons/GridPawnLoader/GridPawnLoaderButton.tscn").instance()
	add_control_to_container(1,loader_ui)

func remove_addon():
	remove_control_from_container(1, loader_ui)
		

add_control_to_container/remove_control_from_container 的第一个参数是一个枚举类型

enum  CustomControlContainer:
	CONTAINER_TOOLBAR = 0
	
	CONTAINER_SPATIAL_EDITOR_MENU = 1
	
	CONTAINER_SPATIAL_EDITOR_SIDE_LEFT = 2
	
	CONTAINER_SPATIAL_EDITOR_SIDE_RIGHT = 3
	
	CONTAINER_SPATIAL_EDITOR_BOTTOM = 4
	
	CONTAINER_CANVAS_EDITOR_MENU = 5
	
	CONTAINER_CANVAS_EDITOR_SIDE_LEFT = 6
	
	CONTAINER_CANVAS_EDITOR_SIDE_RIGHT = 7
	
	CONTAINER_CANVAS_EDITOR_BOTTOM = 8
	
	CONTAINER_PROPERTY_EDITOR_BOTTOM = 9
	
	CONTAINER_PROJECT_SETTING_TAB_LEFT = 10
	
	CONTAINER_PROJECT_SETTING_TAB_RIGHT = 11
