问题描述

Cannot find member “window_fullscreen” in base “OS”.

回溯方法

func _input(event):
	if event.is_action_pressed("toggle_fullscreen"):
		OS.window_fullscreen = !OS.window_fullscreen
		get_tree().set_input_as_handled()

问题截图

解决方案: 实现toggle_fullscreen函数 并替换掉 OS.window_fullscreen = !OS.window_fullscreen

toggle_fullscreen 方法实现

func toggle_fullscreen():
	if DisplayServer.window_get_mode() == DisplayServer.WINDOW_MODE_WINDOWED:
		DisplayServer.window_set_mode(DisplayServer.WINDOW_MODE_FULLSCREEN)
	else:
		DisplayServer.window_set_mode(DisplayServer.WINDOW_MODE_WINDOWED)
