While I'm still waiting for answers, I've thought up new questions.
I've got a spawner using a specific player's serial number as a trigger. The idea is that when he trigger is spawned, he's "knocked out" and transported by the spawner to another location where he'll be in a jail cell. I don't want him to be there for terribly long so I was thinking I could use an XMLAttachment with a time limit on it and when it expires he gets let out.
Anyone able to help me out with this one too?
I'll just keep loading up this post until I get my answers!
