How Do I Make A GUI Stickers Collector?

You put the image id in a value in a folder in Workspace, and you give the sticker on the ground the same name as the number value in the folder. Then, create an onTouch() function. Make it look for the value with the name of the part that got touched. Once it's found it, look for the player of object that touched it. Then if it returns true, it simply makes the image on the gui visible. Like this:

game > Workspace > ImageHolder > SanicSticker

' game > Workspace > SanicSticker > Script V '

local p = script.Parent
p.Touched:connect(function(hit)
    local h  = hit.Parent;FindFirstChild("Humanoid")
    if h then
        local name = p.Name
        local find = game.Workspace.ImageHolder:FindFirstChild(name)
        if find then
            local player = game.Players:GetPlayerFromCharacter(hit.Parent)
            if player then
                local gui = player.PlayerGui:FindFirstChild("StickerGui")
                if gui then
                    local f = gui:FindFirstchild(p.Name,true)
                    if f then
                        f.Visible = true
                    end
                end
            end
        end
    end
end)
