How to do: Stats?

i'm going to be looking into a game where you can do upgrades such as maxhealth and walkspeed.

How I would like to do this is have IntValue's and have scripts work off them and update them as needed. (Such as buying an upgrade)

I feel like there is 2 things that i'm going to need to learn, how to update their humanoids when they join and when they respawn according to the IntValue's inside the players. (Also going to need to learn how to save them when it gets updated and load when a player joins again)

I also feel like i'm going to need to have the local scripts inside StarterGUI.

Is anyone willing to explain everything that I would need to learn or provide me with wiki links for what I will need to learn?

This is perfect. +1 me.

-Messing with Int Values and Data Persistance https://www.youtube.com/watch?v=-BCuOiM14lA

You shouldnt use IntValues for everything. BUT I prefer you'd put them in player or in a model in player

-To do something when they spawn (in the player id prefer you'd put a script that would wait for a bool value in the player when the data loads so it doesnt excecute before data is loaded thus creating false info)

-Haven't tested the code below

function GetStats(directory,value,human)
	local DataDirectory = directory.Parent.PlrDataReady
	while DataDirectory == false do
		wait()
	end
	if directory.Value == value then
		--human.WalkSpeed     Do Stuff Here
	else
		print("Conditions not met by "..plr.Name..".")
		print("Condition: "..value.." "..directory.Name)
	end
end


game.Players.PlayerAdded:connect(function(plr)
	plr.CharacterAdded:connect(function(chr)
		GetStats(plr.Rank,"General",chr)
		GetStats(plr.Rank,"Administrator",chr)
		GetStats(plr.Cash,200,chr)
		GetStats(plr.Job,"Real Estate Agent",chr)
	end)
end)

+1 :D
