when "whatever it is that it's looking for" happens (here the layer moves off x=0) it moves out of its idle state (state 0) and starts the (here) 3-step process to put things right.
the critical item here is that the state<n> subroutines MUST return the next state to process. This can be determined algorithmically - e.g. state 1 might need to decide if state 2 or state 3 should be next (here I've kept it simple -- it's always the next one)
I've not tried to use external functions or to have "state" set by external means, although there's no reason why not (e.g. rather than this layerscript deciding to move out of "idle", some external force can nudge it)
I **should** have made an "idle" function that returns "idle" or "begin"... IOW the "If state == 0 etc" should have gone into a function that returns 0 if still nothing or 1 if there's stuff to do ... but I didn't! (mea culpa!)

Hope that's helpful.
