以下是所有方法的列表：

Getters — Check if the Bumper Switch is currently pressed.

  • pressing — Returns whether the Bumper Switch is being pressed.

Callback — Run code when the Bumper Switch is pressed or released.

  • pressed — Registers a function to be called when the Bumper Switch is pressed.

  • released — Registers a function to be called when the Bumper Switch is released.

Constructors — Manually initialize and configure the Bumper Switch.

# Back up and turn if bumper switch 
# is pressed
while True:
    drivetrain.drive(FORWARD)
    if bumper_1.pressing():

pressed#

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

Usage:
bumper_1.pressed(callback, arg)

参数

描述

callback

先前定义的 函数 在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。更多信息，请参阅带参数的函数](…/Logic/Functions.md#functions-with-parameters)。

 
# Drive forward when bumper switch 
# is pressed
def bumper_pressed():
    drivetrain.drive_for(FORWARD, 100, MM)

bumper_1.pressed(bumper_pressed)

released#

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

Usage:
bumper_1.released(callback, arg)

参数

描述

callback

先前定义的 函数 在保险杠开关释放时执行。

arg

可选。包含要传递给回调函数的参数的元组。更多信息，请参阅带参数的函数](…/Logic/Functions.md#functions-with-parameters)。

 
# Drive reverse when bumper switch 
# is released
def bumper_released():
    drivetrain.drive_for(REVERSE, 100, MM)

bumper_1.released(bumper_released)

构造函数#

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

Bumper Switch#

Bumper creates a Bumper Switch.

Usage:
Bumper(smartport)

范围

描述

smartport

The Smart Port that the Bumper Switch is connected to, written as PORTx where x is the number of the port.

 
bumper_1 = Bumper(PORT1)
# Back up and turn if bumper switch pressed
while True:
    drivetrain.drive(FORWARD)
    if bumper_1.pressing():
        drivetrain.drive_for(REVERSE, 100, MM)
        drivetrain.turn_for(RIGHT, 90, DEGREES)
