行动

pressed

pressed calls a function when the bumper switch is pressed.

Usage:
Bumper1.pressed(callback);

范围	描述
callback	先前定义的当按下保险杠开关时执行的功能。

// Drive forward when the Bumper Switch is pressed
void onBumperPressed() {
  Drivetrain.driveFor(forward, 100, mm);
}

int main() {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  // Call onBumperPressed when the Bumper is pressed
  Bumper1.pressed(onBumperPressed);
}

released

released calls a function when the bumper switch is released.

Usage:
Bumper1.released(callback);

范围	描述
callback	先前定义的在释放保险杠开关时执行的功能。

// Drive backward when the Bumper Switch is released
void onBumperReleased() {
  Drivetrain.driveFor(reverse, 100, mm);
}

int main() {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  // Call onBumperReleased when the Bumper is released
  Bumper1.released(onBumperReleased);
}

pressing

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

• 1 - The Bumper Switch is being pressed.

• 0 - The Bumper Switch is not being pressed.

Usage:
Bumper1.pressing()

参数	描述
	该方法没有参数。

int main() {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  // Drive forward until the Bumper is pressed
  while (true) {
    Drivetrain.drive(forward);

    // If pressed, stop and back up
    if (Bumper1.pressing()) {
      Drivetrain.stop();
      Drivetrain.driveFor(reverse, 100, mm);
      break;
    }

    wait(20, msec);
  }
}

installed

installed returns a Boolean indicating whether the Bumper Switch is currently connected to the Brain.

• 1 – The Bumper Switch is connected to the Brain.

bumper creates an object of the bumper Class in the specified port.

Usage:
bumper Bumper1 = bumper(port);

范围	描述
port	Which Smart Port that the Bumper Switch is connected to as PORT followed by the port number, ranging from 1 to 12.

int main() {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  // Create a Bumper object in Port 3
  bumper CustomBumper = bumper(PORT3);
}
