控制器#
介绍#
VEX AIR 无人机控制器采用 12 个按钮布局和两个操纵杆。这些输入使无人机能够检测按钮按下和操纵杆移动，从而实现交互式和灵敏的控制。
以下是所有可用块的列表：
controller button pressed — Checks if a specific button is currently being pressed.
controller axis position — Reports the position of the joystick along a specified axis.
controller is connected — Reports whether the controller is connected to the drone.
controller battery level — Reports the controller’s battery level.
当控制器按钮时 — 按下或释放按钮时运行一堆块。
当控制器轴改变时 — 当操纵杆位置改变时运行一堆块。
controller button pressed#
The controller button pressed Boolean block reports if a specific controller button is being pressed.
True — The specified button is being pressed.
False — The specified button is not being pressed.
