保险杠

介绍

碰撞开关是一种弹簧式数字传感器，用于检测与物体的物理接触或碰撞。

This page uses bumper_switch as the example Bumper Switch name. Replace it with your own configured name as needed.

以下是可用方法列表：

• pressing – Returns whether the specified Bumper Switch is currently pressed.

• pressed – Registers a function to be called whenever the Bumper Switch is pressed.

• released – Registers a function to be called whenever the Bumper Switch is released.

构造函数 – 手动初始化和配置碰撞开关。

• Bumper – Create a Bumper Switch.

紧迫

pressing returns a Boolean indicating whether the Bumper Switch is currently being pressed.

• True – The Bumper Switch is being pressed.

• False – The Bumper Switch is not being pressed.

Usage:
bumper_switch.pressing()

参数	描述
	此方法没有参数。

# Display a message after bumper_switch is pressed
while not bumper_switch.pressing():
  pass

brain.screen.print("Bumper Switch pressed!")

按下

pressed registers a function to be called whenever the Bumper Switch is pressed.

Usage:
bumper_switch.pressed(callback, arg)

参数	描述
callback	一个先前定义的函数，当按下保险杠开关时执行。
arg	可选。包含要传递给回调函数的参数的元组。有关更多信息，请参阅带参数的函数。

def my_function():
  brain.screen.print("Pressed")

# Call my_function whenever bumper_switch is pressed
bumper_switch.pressed(my_function)

发布

released registers a function to be called whenever the Bumper Switch is released.

Usage:
bumper_switch.released(callback, arg)

参数	描述
callback	先前定义的 函数，当 Bumper 开关释放时执行。
arg	可选。包含要传递给回调函数的参数的元组。有关更多信息，请参阅带参数的函数。

def my_function():
  brain.screen.print("Released")

# Call my_function whenever bumper_switch is released
bumper_switch.released(my_function)

构造函数

Constructors are used to manually create Bumper objects, which are necessary for configuring a Bumper Switch outside of VEXcode.

Bumper

Bumper creates a Bumper Switch.

Usage:
Bumper(port)

范围	描述
port	The 3-Wire Port that the Bumper Switch is connected to: On the V5 Brain – brain.three_wire_port.x where x is the number of the port. On a 3-Wire Expander – expander.a where expander is the name of the expander instance.

# Create a Bumper Switch in Port A
bumper_switch = Bumper(brain.three_wire_port.a)
