The Dink Network

That isn't directly possible, only by some complex scripting which I don't feel like doing now. The map cursor is an extra parameter for the show_bmp() or something command. It'll automatically center on the screen Dink is on, except when going indoors. Yes, there is some buggyness with warps, but that's a Dink Engine limit.

Your idea involves a similar loop as the one in SimonK's input box for riddles.
