Events and actions
So far, you’ve seen how Edge Animate uses triggers to automatically execute JavaScript when the playhead reaches a certain point on the Timeline. You added a trigger at the end of the animation to create a loop. The other two ways with which Edge Animate adds JavaScript is with events and actions.
Events are occurrences that happen in Edge Animate that it can detect and respond to. When an event is detected, you provide actions as a response.
It’s useful to think of interactions in terms of events and actions. When you click on a menu button (event), more options may expand (actions). When you roll over a button (event), a triangular play icon may appear on it (actions). In the next section, you’ll add thumbnail images to the Stage. When the user clicks on each thumbnail (event), the playhead will move to a new position on the Timeline (actions) to show a particular image from the travel slideshow.
