Help With a Monster

[Rownbear]

You could use a timer, so after about 20 seconds he despawn, depends how far away you want him to walk until the timer goes off.

Or you can put like they said a removemonster script box he walks into to disappear. BUT you put the removemonster scriptbox unactive and another script box which enables the removemonster scriptbox further inside the room. So he walks through the removemonster script which is unactive and then through the scriptbox that activates it. when he walks out the hall the removescriptbox will be enabled and he's gone. Hope it didnt get too confusing.
