在这段示例代码中,我们首先导入keyboard库,然后定义了一个回调函数on_key_event,用于处理按键事件。接着我们通过keyboard.on_press_key方法来注册按键a的按下事件,并指定回调函数on_key_event。最后调用keyboard.wait()来等待按键事件。 流程图 下面是一个流程图,展示了监控用户按键的整体流程: 开始导入keyboard库定义...

All keyboard input in arcade is handled by .on_key_press() and .on_key_release(). You can find the code for making Roz move via the keyboard in arcade_platformer/06_keyboard_movement.py. First, you need two new constants: Python 23# Player constants 24GRAVITY = 1.0 25PLAYER_START_...
Similarly to the rotation, this will check the current state of the keyboard, not the keypress events. The constant for Up is pygame.K_UP: Python def _handle_input(self): for event in pygame.event.get(): if event.type == pygame.QUIT or ( event.type == pygame.KEYDOWN and event....
Add a key to the model (specification) of the keyboard. Parameters: name (str)– The text or label you can see on the key. text (str)– The text that will be typed if you press OK on the key. If not specified, defaults to name if name is exactly 1 character long, otherwise it...
