The Scene Graph Timer Utility triggers scripted actions at a set interval or after a set duration, so gameplay logic runs directly off elapsed time.
The utility exposes a timer class configured with a precise interval or a duration, and runs the scripted action attached to it when that time elapses. Developers set the timing of each timer independently, which is what makes reactive systems and time-based challenges such as countdowns and recurring events expressible in terms of elapsed time.
Quite easy to code verse timers ourselves already, fairly extensive options including getting real time. Obviously a nice add but not sure why so sought after?
