Make a new door combo set with the shutter door open, and the open doors closed. Make all the doors you want to stay open are 1-way shutters. The door you want to close when you push the block or kill the enemies should be a shutter (normal). When the player walks in, all doors will be open. Then, when they complete the room goal, the doors will close.
Doors Shut
That could work well with an event!!!! Like, when you kill the enemies, a boss appears! I might use that in a quest!
Hmmm... I might just use that in the battle arena I've been planning. Thanks for the tip!
Goody! You just gave me another idea for something I'm going to do tomorrow. :evil:
