objTby

objTby is the master object for textboxy. Currently, it serves the following purpose:

• Call tby_init_scribble()
• Initialize globals tby_branches and tby_tooltips
• Handle TbyType.Wait instruction via alarm
• Draw all tooltips
• Clear all data structures on game end
• Clear all branches on room end

For this to work, the object is created in the first room via a gml_pragma call to tby_globals(). It then sets its own layer to the text layer in the Game Start event.
