This door will (for example) only allow players with BL_ID 130, 666 and 1337 through.

When the door is set to
BLID Allow or
BLID Deny, you should enter IDs in the textbox, separated by spaces.
BLID Allow only allows players with those IDs will be allowed in. (make sure to include your own!)
BLID Deny will allow anyone to enter, except players with those IDs.
In the example, I set the onDoorStuckPlayer event to open the door again for anyone, so that players do not get 'jammed' in the door. If the door is going to automatically open on a trigger or relay, it's best to use
Unrestricted.
