Thx for the reply. Well I think I didn't explained as I wanted.
I want to block both CT and T, because:
Point of the "noob" (that can't bhop) can be T or CT, and I want to make fair for him.
Point of the "leet" (that can bhop) can be T or CT killing or escaping, making it unfair.
I want a command that block and the other that unblock, because in the beggining of the vent I will block and at the end I'll unblock, so they can jump after going thru the vent
