Overview

StackableCommand is the parent class of any command that creates a branch in the logic: such as If, Loop, etcetera.

Any child that wants to do more than stand alone must inherit from StackableCommand. We recommend setting @called_as, so all of StackableCommand’s ways of closing blocks work.
