Make monster destory the door

[Kullin]

1. how to make the enemy destory the door? if i Close the door he just stands there, and notice, i only want him to destory the door and dont destory the door and come to me

2. Make the enemy dissappear if he cant find me, it isn't necessary but just to learn something

Sorry, i know i'm annoying xd

1. Make a pathnode thrugh the door and he will break it, then use the functin
SetEntityActive("Nameofthemonster", false);

2. add a timer and use the same function.

hope that was what you asked for.
