trigger event mechanism problem?

[ggslayer]

I see the example code and the flutter sdk code about the trigger event, But i don't understand the componts/fromtime/totime parameter means, Is there any detailed description about the event's usage?

The idea for ActorAnimation.triggerEvents(components, fromTime, toTime, triggerEvents) is to have the animation give you back a list of all triggered events in a time window that goes from fromTime to toTime. All triggered events will be added to triggerEvents.

More specifically you'd want to call that function once per frame, where

• components array is the list of the components in the artboard (i.e. ActorArtboard.components)
• fromTime is the time of the last frame
• toTime is the timem of the current frame Now process the events in triggerEvents for that time span.
