How to make wall with timer that occasionally is open, and closes after certain time?

Hi, this is how you would make one. feel free to change the wait times to work for you. But don't play around with the wait(2) Make sure you create a part and name it wall and insert a script here is the script:

wait(2)

    while true do

        wait(30)

    script.Parent.Parent.wall.CanCollide = true

    print("Wall closing")

        wait(300)

    script.Parent.Parent.wall.CanCollide = false

    print("Wall opening")

        wait(30)

    end

Hope this helps!!
