Need help with Tag Game

I am currently making a “Tag Extreme” game, and I need to make a little room for the tagger to be in for 15 seconds, then release him. Is there any way I can make smth like that?

Here is how you do it:
First, make a barrier as the exit to your room.
Second, make a trigger that has a delay of 15 seconds. It cannot be triggered by player collision, and not visible in game.
Third, make a lifecycle on game start.
Wire the lifecycle to the trigger, and make it trigger the trigger.
Make the trigger deactivate the barrier.

If nothing helps you then notify me using@Crimson_Knight and I will see if I can do anything. I suspect it will have something to do with teleporters and triggers…
