Sending data using TeleportService?

Sort of...

This method would involve DataStores.

Basically you'd have two spawns in the same position. Name one of them LoadData and the other SpawnPoint [the spawnpoint would spawn normal users on it...]

Now you'd have to make this spawnpoint named LoadData [from now on it's just "the spawnpoint"] inactive so people don't autospawn on it. Do this in its properties.

Now view this example from the Roblox Wiki

local TeleportService = game:GetService("TeleportService")
local level1Id = 408502340 -- your game
local level2Id = 408502380 -- your destination
 
local level1SpawnName = “LoadData"
local player = -- your method of finding the player.
if player then TeleportService:TeleportToSpawnByName(level1Id , level2SpawnName, player)
end
end
 
script.Parent.Touched:connect(onTouched)

You'd then want to include some DataStore code, doing the following:

• Updating somewhere in the Datastore to store some info, maybe a table of numbers[that would translate into different functions in the main code, the code below would print the first value and you can convert that into whatever you want:

print(yourTable[1])

• Writing a Getasync script for when a player is added [I'm not sure how you'd detect whether the player had come from another game] to find these tables as I said and then running a function to translate them into different things.

local DataStoreService = game:GetService("DataStoreService")
local Players = game:GetService("Players")
 
local function onPlayerAdded(player)
	local scope = player.UserId
	local loadData = DataStoreService:GetDataStore("LoadData")
	pcall(function()
	loadData:GetAsync(scope)
	end)
end
 
Players.PlayerAdded:Connect(onPlayerAdded)

• Writing a SetAsync script to override the string in the datastore thus resetting it and making a clean area for more code:

local DataStoreService = game:GetService("DataStoreService")
local playerStats = DataStoreService:GetDataStore("LoadData")
local scope = player.UserId
pcall(function()
	loadData:SetAsync(scope, nill)
end)

This all should work, but keep in mind the following:

• ALWAYS pcall() DataStore updating/reading functions. If these fail, any code after them won't run. A pcall won't come accross this hurdle

• If creating remoteevents to update DataStores, make sure you protect them somehow against exploiters. This is the same if you make one for TeleportService, another exploiter favourite.

• All of this code is open-sourced and mostly pulled from the Roblox Wiki. I edited it for your needs, just set your player finder to the variable "player" and have basic understanding on how these work.
