Making an exception to an every turn rule

[Zed (Zed Lopez)]

@Draconis

all rulebooks in Inform can, by default, care about the current action. You can say “every turn of waiting” the same way you say “before waiting” or “instead of waiting”.

I had thought that wouldn’t work 'cause I was half-remembering Supplied missing noun forgotten by end of turn (so scene change fails)? . We’re actually warned in WI 12.10 to not use the current action phrase in an every turn rule. But depending on what the action had been in an every turn preamble is ok. Weird.

I was forgetting that ‘involved’ is a built-in concept with the if [action] involves [object] phrase, so maybe…

the previous action is an action that varies.
before doing anything, now the previous action is the current action.
every turn when the location is the checkout:
  unless the previous action involves the cashier, say "whatever."

But this would fail to activate on, say, examining the cashier, so @Draconis’ specifying of the engaging in conversation kind of action would allow more control.
