Sooooooo you want a security door there are a few different ways but I’m going to cover just two ways
First way:
Materials needed: Barrier and smth to deactivate the barrier (like a sentry)
Step one: Place down a sentry somewhere on the map (I’m using a sentry) and find the option “ when knocked out transmit on”
Step Two: go to the building your making the door for and place down a barrier in the entrance then find the option “deactivate when receiving on” and put in the SAME channel u used on the sentry
Method 2
Materials needed: trigger, item checker and barrier
Step one: place the barrier at the entrance of the building you want to secure. Place the trigger somewhere nearby
Step two: Find the “transmit on channel when triggered” and name the channel whatever you like. Place a checker and make it check for whatever item you want your players to use to open the door
Step three: make the checker check when it receives a signal from the SAME channel you used for the trigger.
Your done, have fun with your security door!
