Lock Pose

What is Lock Pose?

Lock Pose is a special circumstance when you want to stay in a position and become incredibly difficult to move. All of the wheels point inwards to an X formation. This should only be used when no other input is given or else there could be some breaking undefined behavior that happens.

How do I use Lock Pose?

You call the function SwerveDrive.lockPose() repeatedly instead of passing any controller input.

public class RobotContainer
{

  // Replace with CommandPS4Controller or CommandJoystick if needed
  final CommandXboxController driverXbox = new CommandXboxController(0);
  // The robot's subsystems and commands are defined here...
  private final SwerveSubsystem drivebase = new SwerveSubsystem(new File(Filesystem.getDeployDirectory(),
                                                                         "swerve/neo"));

  /**
   * The container for the robot. Contains subsystems, OI devices, and commands.
   */
  public RobotContainer()
  {
    // Configure the trigger bindings
    configureBindings();

    Command driveFieldOrientedDirectAngleSim = drivebase.simDriveCommand(
        () -> MathUtil.applyDeadband(driverXbox.getLeftY(), OperatorConstants.LEFT_Y_DEADBAND),
        () -> MathUtil.applyDeadband(driverXbox.getLeftX(), OperatorConstants.LEFT_X_DEADBAND),
        () -> driverXbox.getRawAxis(2));

    drivebase.setDefaultCommand(driveFieldOrientedDirectAngleSim);
  }

  /**
   * Use this method to define your trigger->command mappings. Triggers can be created via the
   * {@link Trigger#Trigger(java.util.function.BooleanSupplier)} constructor with an arbitrary predicate, or via the
   * named factories in {@link edu.wpi.first.wpilibj2.command.button.CommandGenericHID}'s subclasses for
   * {@link CommandXboxController Xbox}/{@link edu.wpi.first.wpilibj2.command.button.CommandPS4Controller PS4}
   * controllers or {@link edu.wpi.first.wpilibj2.command.button.CommandJoystick Flight joysticks}.
   */
  private void configureBindings()
  {
    driverXbox.x().whileTrue(Commands.runOnce(drivebase::lock, drivebase).repeatedly());
  }

  /**
   * Use this to pass the autonomous command to the main {@link Robot} class.
   *
   * @return the command to run in autonomous
   */
  public Command getAutonomousCommand()
  {
    // An example command will be run in autonomous
    return drivebase.getAutonomousCommand("New Auto");
  }

  public void setDriveMode()
  {
    //drivebase.setDefaultCommand();
  }

  public void setMotorBrake(boolean brake)
  {
    drivebase.setMotorBrake(brake);
  }
