Apologies that above one is for roblox, this one is for brickplanet:

local Players = game:GetService("Players")

-- Function to teleport a player to a specified location
local function teleportPlayer(player, location)
player.Character.HumanoidRootPart.CFrame = location
end

-- Bind the function to a chat command
game.Players.PlayerAdded:Connect(function(player)
player.Chatted:Connect(function(message)
-- Check if the message is the teleport command
if message:lower() == "!teleport" then
-- Get the target player
local targetPlayer = Players:GetPlayerFromCharacter(player.Character)
-- Set the target player's location
teleportPlayer(targetPlayer, CFrame.new(0, 100, 0))
end
end)
end)
