Looks good, for a script from scratch.
But, did you mean LS:RP, or LSL:RP?
Just out of curiosity.
You could also make a dynamic building system. Allowing the players to create buildings, anywhere IG.
Such as, /createbuilding > Pop's up a dialogs: Interior - Exterior - Done.
Interor - Pop's up anther dialog, with a list of every interior, catgorized by the type: House/Business/Government/Other etc. Then once it's selected it will auto set the /enter point at the door of that interior.
-Exterior: Will simply place the Icon, and the /enter position at your current position.
-Done. Well will complete the building and save it.
Yes, it will take some time, doing all the dialog, and /save'ing at every door of the interiors.
But I have done it myself already, and trust me. It saves ALOT of time when you can create buildings IG and not have to code them into the actual script.
