Controller

Introduction

The One Stick Controller features a 4-button layout and a joystick that functions as both an analog input and a pressable button. These inputs allow the robot to detect button presses and joystick movements, enabling interactive and responsive control. Below is a list of all available blocks:

• controller button pressed? – Checks if a specific button is currently being pressed.

• controller axis position – Returns the position of the joystick along a specified axis.

• when controller button – Runs a stack of blocks when a button is pressed or released.

• when controller axis is changed – Runs a stack of blocks when the joystick position changes.

controller button pressed?

The controller button pressed? block returns an integer indicating whether a specific controller button is being pressed.

• 0 - The controller button is not being pressed.

• 1 - The controller button is being pressed.

The Controller button pressed Boolean block.

  forever
  if <controller button [up v] pressed?> then
  move [forward v]
  else
  stop all movement

controller axis position

The controller axis position block returns the position of the joystick along a specified axis as an integer from -100 to 100.

The Controller axis position reporter block.

    (controller axis [1 v] position)

Parameters	Description
axis	The axis to return the position of: 1 2

Example

  when started :: hat events
  [Move forward when the joystick is moved up.]
  forever
  if <(controller axis [1 v] position) [math_greater_than v] [0]> then
  move [forward v]
  else
  stop all movement

when controller button

The when controller button block activates the attached stack of blocks when the button is being pressed or released.

The When Controller button hat block.

when controller axis is changed

The when controller axis is changed block activates the attached stack of blocks when the axis is being changed.

The When Controller axis is changed hat block.

    when controller axis [1 v] is changed :: hat events

Parameters	Description
axis	The axis to check for change: 1 2

Example

  when controller axis [1 v] is changed :: hat events
  [Move forward when the joystick is moved.]
  move [forward v] for [50] [mm v] ▶
