give a certain player a starter character script?

you need to check if the player exist in the game and if the player exist then put the script into that players backpack

EDITED!

Just like this:

local MyScript = script.Parent
MyScript.Disabled = true

function GiveScript(p)
    local NewScript = MyScript:Clone()
    NewScript.Parent = p.PlayerScripts
    NewScript.Disabled = false
end

GiveScript(--[[Player here, I'll just put myself if I was in the game,]] game.Players["MrOpScripter"])
