I created a tutorial on the main ROBLOX Website. I will be going through all of the need to know stuff in here.

First thing is Saving. You cant save progress unless a players Data has been loaded. There is a method to wait until the players Data is loaded. Although we have to start off with a more Basic line. This line is what triggers the function. Here us a Function which will trigger when a player leaves the game.

game.Players.PlayerRemoving:connect(function(player)

Now we must incorporate the line to wait until the players Data is ready

player:WaitForDataReady()

The next line is what you would like to save. In here we will be saving a players KOs value.

player:SaveNumber("KOs", player.leaderstats.KOs.Value)

Now as with all functions we need an end

end)

Here is the complete script:

game.Players.PlayerRemoving:connect(function(player)
player:WaitForDataReady()
player:SaveNumber("KOs", player.leaderstats.KOs.Value)
end)

The main line is line 3. Inside the brackets are arguments. The first argument is what you will save the Number as. The second argument is the value you are saving. In this case we are saving the value of Knock outs inside the leaderstats inside the player.

Please vote on the poll, I will use the results to improve future Tutorials

Could have been a little better, like also explaining the loading part and the sorts you can save/load. I.E Boolean/Number/String etc

well explained! =D
