(That should really be in its own function, but whatever.) https://smaugmuds.afkmods.com/topic/reverse-exit-4327/&p=20151#p20151 Tue, 16 Feb 2010 11:26:23 CST SWR FUSS nobody@example.com (David Haley) https://smaugmuds.afkmods.com/topic/reverse-exit-4327/&p=20149#p20149 I'm trying to acquire the reverse of a given exit, say, if supplied with west, it'll return east, where west is 3 and east is 1. Between rev_dir[] and get_exit_to(), I believe there is a simple way to do it, but without proper comments on the functions I have been unable to figure it out. https://smaugmuds.afkmods.com/topic/reverse-exit-4327/&p=20149#p20149 Tue, 16 Feb 2010 11:12:34 CST SWR FUSS nobody@example.com (Banner)
