I play at Realms; it's one of the more easily mapped MUDs out there. Here are some triggers you might put in the Map Properties:Map Script.
#TR {*is closed.} {#NODIR}
#TR {Alas, you cannot go that way.} {#NODIR}
#TR {You start to climb... but lose your grip and fall!} {#NODIR}
#TR {Nah... You feel too relaxed...} {#NODIR}
#TR {It is pitch black ...} {#OK}
#TR {You are still fighting!} {#NODIR}
#TR {You recite {recall scroll|a scroll of escape.}} {#RECALL}
#TR {Ok.} {#NOMAP}
#TR {You can't do that sitting down.} {#NODIR}
#TR {Your mount is too exhausted.} {#NODIR}
#TR {You'd need a boat to go there.} {#NODIR}
#TR {{@leader} {leaves|floats|flies} (%w).} {#VAR leaderwent %1}
#TR {You follow {@leader}.} {#MO @leaderwent}
#TR {..Everything begins to fade to black.} {#TE altar Darkhaven}
#TR {You'd need to fly to go there.} {#NODIR}
#TR {You are too exhausted.} {#NODIR}
You'll probably come up with some of your own too.
