Skrpit for no Nether Roof

[fadsiadsaffd]

Hey Im really bad a skript and I have a server with my friends from school. I was wondering if someone could make me a skript that prevents people from going to nether roof (or makes them take damage) as some of my friends do this and crash the server. 

Thanks so much!!! :D

You could track the y-coord of the player and if their y-coord is greater or equal to the one you proposed, do whatever you want to them. I made a script for that purpose but it's right out of my head so I haven't tested it for errors yet:

 

#You can change the number of seconds this event happens, but I made it 5 to prevent lag.
every 5 seconds:
	loop all players:
		if loop-player's world = "name of the nether world":
			if loop-player's y-coord >= 127:
				kill loop-player
