Diggidy There is a event that is triggered each time an object is focused. You can use it to handle the gamepad input on it, if it's a clickable button :
void Start()
{
TutorialEvents.OnTutorialFocus += OnTutorialFocus;
}
void OnTutorialFocus(string objectName, Vector3 rectCenterPosition)
{
// Handle the gamepad input on the object called objectName
}
