ESC is a fairly simple to use method of scheduling scripted events. It essentially functions as a delayed version of ExecuteScript() with the added benefit of being (optionally) persistent and using no DelayCommand() calls.
These scripts were written for and tested on the roleplay-based persistent world Outpost of the Empire (www.outpostpw.com). Through using ESC, we were able to eliminate area heartbeat events altogether and reduce the amount we used long delay commands (as in pseudoheartbeats). Hopefully you can find as many little uses for this versitile script.
