I need help with something with teleportals?

Well im making a zombie game and I need to know how to teleport players to a new map.

There are two ways to teleport players.

1. character:MoveTo(Vector3.new(#,#,#)) Call the MoveTo() method on a character model.

2. character.Torso.CFrame = CFrame.new(#,#,#) Change the CFrame of the character's torso.

As for teleporting ALL players, for that we need to use a for loop.

for i,v in pairs(game.Players:GetPlayers()) do
	local character = v.Character
	--teleport stuff
end

Here, we are going through all the players 1 at a time. v equals the player we are currently at. Since v changes to the current player each time the loop iterates, we can affect all players in a very short amount of time.

Hope I helped!
