Introduction

Teleportation is a term given to the act of moving a group of Parts (most of the time, a player's character) to a certain coordinates. In ROBLOX, setting the Position property of Parts would disconnect the Part from any other connected Parts and break the model. Therefore, one cannot use the following to teleport a player because it would disconnect the Torso from the Head.

game.Workspace.Player.Torso.Position = Vector3.new(0, 50, 0)

To correctly teleport a player without killing them, you must use the CFrame property and use the CFrame data type instead.

game.Workspace.Player.Torso.CFrame = CFrame.new(Vector3.new(0, 50, 0))

CFrame versus MoveTo

MoveTo can be used in place of setting the CFrame of one brick in the model. MoveTo will only change the Position/CFrame of the Parts in the model if the Parent property is the Workspace.

Teleporting All Players

One can teleport all players in the game by iterating over each one of their Characters and setting the CFrame accordingly. However, you should be careful and offset the target positions so that the players' torsos do not overlap.

target = Vector3.new(0, 50, 0) --could be near a brick or in a new area
for i, v in pairs(game.Players:GetChildren()) do
v.Character.Torso.CFrame = CFrame.new(target + Vector3.new(0, i * 5, 0)) --add an offset of 5 for each character
end

The above code would teleport each player to the position (0,50,0), going up 5 for each character so they do not overlap. If you place players on top of each other, make sure the area does not have a ceiling so players aren't put on top of a building.

Teleportation Effects

You can add in fading effects by using for-loops to set the Transparency of your limbs.

player = game.Players.Player --you might want to change this...
target = Vector3.new(20, 10, 20) --...and this

function fadeTo(a, b, c)
for i=a, b, c do --go from a to b, counting by c
for j, v in pairs(player.Character:GetChildren()) do --for each of the objects in the character,
if v:IsA("Part") then --check if it's a part, and if so
v.Transparency = i --set it's transparency
end
end
wait(0.1)
end
end

fadeTo(0, 1, 0.1) --fade out,
player.Character.Torso.CFrame = CFrame.new(target) --teleport the player
fadeTo(1, 0, -0.1) --fade back in

Other effects may include making the player rise up off the ground, become shiny by changing Reflectance, or spin using BodyAngularVelocities.
