Triggers
Triggers are fired by events. You can use
triggers to show and hide layers and windows, show answers, activate
topics, and perform model actions.
One-Time Triggers
One-time triggers fire exactly once per time you've called "Start
GBS". You could use them for guide video or introductions to
screens, or annoying remediation you'd like only to see once.
Next Triggers
Next-triggers are triggers that are run after the current trigger
fires, so if Trigger A has Trigger B in its next-trigger slot, Trigger
B will fire any time Trigger A fires, no matter what event is listed
in Trigger B.
If Trigger A is a one-time trigger and Trigger B is an every-time
trigger, Trigger A will fire once but trigger B will fire any time
Trigger A might have fired, whether A fired at all! This is to
facilitate above-mentioned guide-video, since guides should happen the
first time you click on this button, but you might want some standard
video to play every time you enter a screen (like, say, video of your
fumarole rumbling).
