Thotter has graced us with his skills and has created custom walkin/walkout for mobs. This means you can create a walkin and walkout for any of your mobs in the game - no more needing to script it on every room for every mob. Of course, if you don't want to use it, you just leave the choices blank and the default will still be used.
The variables are $n for the mobs name and $n and $d for the direction. For example:
P) Arrive : $n has arrived from the $d, hopping like a rabbit.
Z) Leave : $n marches $d, muttering something about demonstrating custom moves.
Put on a cityguard looks like this:
A cityguard marches north, muttering something about demonstrating custom moves.
A cityguard has arrived from the north, hopping like a rabbit.
