Controller#
Introduction#
The Controller category includes blocks for detecting and responding to input from the VEX IQ (1st gen) Controller. These blocks allow your robot to react to button presses, monitor joystick positions, and control how input mappings are applied during a project.
Below is a list of all blocks:
controller button pressed? — Returns a Boolean indicating whether a button is currently pressed.
controller axis position — Returns the current joystick axis position.
controller enable/disable — Temporarily enables or disables controller actions.
when controller button — Runs a stack when a specific controller button is pressed or released.
when controller axis is changed — Runs a stack when a joystick axis is moved.
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.
