BEGIN

All Staps (6):

Stap: 1

• We need to detect when a player joins. This has one argument, the player.

game.Players.PlayerAdded:Connect(function(Player)
   -- We now have the player detected.
end)

Stap: 2

• Because StarterGear doesn't always work, I detect when the player spawns.

Player.CharacterAdded:Connect(function(Character)
   -- We now have detected our Character.
end)

Stap: 3

• Let we check if the player owns the gamepass with a local function.

local function CheckGamepass(PlayerId, AssetId)
   local MarketPlace = game:GetService("MarketplaceService")
   if MarketPlace:UserOwnsGamePassAsync(PlayerId, AssetId) then
       return true
   end
   return false
end

Stap: 4

• Now we need to add the tool if the player owns it.

local function AddTool(Player, Tool)
    local Location = game.ServerStorage
    if Location then
        local GamepassTool = Location:FindFirstChild(Tool)
        if GamepassTool then
            local NewTool = GamepassTool:Clone()
            NewTool.Parent = Player:WaitForChild("Backpack")
            Player:LoadCharacter()
        else
            warn("Tool doesn't exit into the location.")    
        end
    else
        warn("Cannot find Location for the gamepass tools.")
    end
end

Stap: 5

• Now we need to add the last things to let everything works.

local function CheckGamepass(PlayerId, AssetId)
    local MarketPlace = game:GetService("MarketplaceService")
    if MarketPlace:UserOwnsGamePassAsync(PlayerId, AssetId) then
        return true
    end
    return false
end

local function AddTool(Player, Tool)        
    local Location = game.ServerStorage
    if Location then
        local GamepassTool = Location:FindFirstChild(Tool)
        if GamepassTool then
            local NewTool = GamepassTool:Clone()
            NewTool.Parent = Player:WaitForChild("Backpack")
            Player:LoadCharacter()
        else
            warn("Tool doesn't exit into the location.")    
        end
    else
        warn("Cannot find Location for the gamepass tools.")
    end
end

game.Players.PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
        if CheckGamepass(Player.UserId, 1234567) then
            AddTool(Player, 'Glock-18')
        end
    end)
end)

Stap: 6

• Do you have more then 1 gamepass? Replace it to this! Don't forget the local functions.

game.Players.PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
        if CheckGamepass(Player.UserId, 1234567) then
            AddTool(Player, 'Glock-18')
        elseif CheckGamepass(Player.UserId, 1234567) then
            AddTool(Player, 'BoomBox')
        elseif CheckGamepass(Player.UserId, 1234567) then
            AddTool(Player, 'EarBuds')
        end
    end)
end)

THE END

More Explanation And Hints:

Stap 5: You need to replace "Location = game.Servertorage" to something else, when you have the tool somewhere else, like: "Location = game.Workspace".

Stap 6: Only needed if you have more then one gamepass in your game. Don't forget to replace the names, like: "EarBuds" to "Scooter".

Remember, this script need to be in a 'Script' and not in a 'LocalScript'

Hopefully you now know how to make a Gamepass Tools script! If you want more tutorials from me, please leave a review!
