Description

"Many gamers expect your game to respond to \"standard\" shortcuts, and the standard shortcut to toggle between fullscreen and windowed mode is `ALT+Enter`, `\u2318+Enter` or `F11` . You can easily make your game handle this in a few easy steps:\r\n* Create a global input listener script that can react to global shortcuts\r\n* Create a global shortcut for fullscreen using the project settings \"Input map\"\r\n\r\n## Create a global shortcut\r\nFrom the Godot editor, choose \"Project\" -> \"Project settings\" and select the \"Input map\" tab:\r\n\r\n\r\nIn the \"Add new action\" field, type \"fullscreen\" and click \"Add\", this will add a new global input action that your code can check. To trigger this action, you need to assign one or more shortcut keys. To do this, click the `+` sign at the end of the line that was just added in the list. (if you have many shortcuts defined, you may need to scroll or use the \"Filter\" to find it). This will open a popup that lets you assign the keyboard combination:\r\n\r\n\r\nPress the shortcut key you want to add, in this case, press the `ALT+Enter` key combination, and click \"Ok\". Repeat this to add other shortcut keys, like `F11` if you want your game to also react to this shortcut. This should give you a list that looks like this:\r\n\r\n\r\nNow we are ready to listen to this shortcut being triggered.\r\n\r\n## Create a global input listener script\r\n(If you already have a global input listener script, you can skip this step) Create a file called \"input_listener.gd\" somewhere in your project. We will autoload this file by going to \"Project\" -> \"Project settings\" and selecting the \"Globals\" tab:\r\n\r\n\r\nFrom this tab, either type in the path to your `input_listener.gd` script or use the file picker to select it. Name it `InputListener` and click \"Add\":\r\n\r\n\r\nThis will make your `input_listener.gd` automatically load when the game starts, and lets it run in the background all the time.\r\n\r\n## Create an input listener\r\nTo make your game toggle between fullscreen and windowed mode, create an `_input()` listener method that will detect when the fullscreen keyboard combination is being pressed:\r\n```\r\nfunc _input(event: InputEvent) -> void:\r\n if event.is_action_pressed(\"fullscreen\"):\r\n if get_window().mode == Window.MODE_FULLSCREEN:\r\n get_window().mode = Window.MODE_WINDOWED\r\n else:\r\n get_window().mode = Window.MODE_FULLSCREEN\r\n```\r\n\r\nNow run your game and watch it toggle between windowed and fullscreen mode when you press `ALT+Enter` or `F11`!"

Main code

extends Node

func _input(event: InputEvent) -> void:
  if event.is_action_pressed("fullscreen"):
    if get_window().mode == Window.MODE_FULLSCREEN:
        get_window().mode = Window.MODE_MAXIMIZED
      else:
        get_window().mode = Window.MODE_MAXIMIZED
