How to save weapon's stats ?

Hello there, RBLXNogin here and the solution to your problem is something known as "Leaderstats". In any program, application, and even game saving player and user data is an essential. Using leaderstats, the game developer can create and maintain functions that allow the game to save player data.

according to ROBLOX, a leaderboard as an object that is named as 'leaderstats' and is located inside the player. The data inside the leaderboard is defined as a value object inside the leaderstats object (Player>leaderstats>ValueObject). Now that you understand basics of leaderboards, let me show you a script that creates cash for the player.

You want to save playerdata, so here is the solution. The first thing you need to do is insert a script inside the workspace (script not localscript). After that, insert the code that creates the leaderboard. As an example, I am going to create a script that creates a leaderboard for the amount of money you have, however you can customise it to your own needs.

function OnEnter(plr)
    local leaderstats = Instance.new("Folder")
    leaderstats.Parent = plr
    leaderstats.Name = "leaderstats"


    local weapon = Instance.new("StringValue")
    weapon.Name = "CurrentWeapon"
    weapon.Value = "GunV2" -- name of weapon. You can change or add a script to automatically do so.
end

game:GetService("Players").ChildAdded:Connect(OnEnter)

After you create your leaderstats (to set and change weapon values within a player). You can use something known as DataStoreService (DSS) to save the values.
