So, I was following a youtube tutorial (How to Make a Custom Backpack GUI | Roblox Scripting Tutorial - YouTube) to make a custom inventory system, and I’ve done all of it, however I’m not sure how I can add images for each different tool. The script is
game:GetService('StarterGui'):SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)
--variables
local uis = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local char = workspace:WaitForChild(player.Name) -- added WaitForChild
local bp = player.Backpack
local hum = char:WaitForChild("Humanoid")
local frame = script.Parent.Frame
local template = frame.Template
local equipped = 0.2 -- icon transparencies
local unequipped = 0.7
local iconSize = template.Size
local iconBorder = {x = 15, y = 5} -- pixel space between icons
local inputKeys = { -- dictionary for effective referencing
["One"] = {txt = "1"},
["Two"] = {txt = "2"},
["Three"] = {txt = "3"},
["Four"] = {txt = "4"},
["Five"] = {txt = "5"},
["Six"] = {txt = "6"},
["Seven"] = {txt = "7"},
["Eight"] = {txt = "8"},
["Nine"] = {txt = "9"},
["Zero"] = {txt = "0"},
}
local inputOrder = { -- array for storing the order of the keys
inputKeys["One"],inputKeys["Two"],inputKeys["Three"],inputKeys["Four"],inputKeys["Five"],
inputKeys["Six"],inputKeys["Seven"],inputKeys["Eight"],inputKeys["Nine"],inputKeys["Zero"],
}
-functions
function handleEquip(tool)
if tool then
if tool.Parent ~= char then
hum:EquipTool(tool)
else
hum:UnequipTools()
end
end
end
function create() -- creates all the icons at once (and will only run once)
local toShow = #inputOrder -- # operator can only be used with an array, not a dictionary
local totalX = (toShow*iconSize.X.Offset)+((toShow+1)*iconBorder.x)
local totalY = iconSize.Y.Offset + (2*iconBorder.y)
frame.Size = UDim2.new(0, totalX, 0, totalY)
frame.Position = UDim2.new(0.5, -(totalX/2), 1, -(totalY+(iconBorder.y*2)))
frame.Visible = true -- just in case!
for i = 1, #inputOrder do
local value = inputOrder[i]
local clone = template:Clone()
clone.Parent = frame
clone.Label.Text = value["txt"]
clone.Name = value["txt"]
clone.Visible = true
clone.Position = UDim2.new(0, (i-1)*(iconSize.X.Offset)+(iconBorder.x*i), 0, iconBorder.y)
clone.ImageTransparency = unequipped
local tool = value["tool"]
if tool then
clone.Tool.Image = tool.TextureId
end
clone.Tool.MouseButton1Down:Connect(function() -- click icon to equip/unequip
for key, value in pairs(inputKeys) do
if value["txt"] == clone.Name then
handleEquip(value["tool"])
end
end
end)
end
template:Destroy()
end
function setup() -- sets up all the tools already in the backpack (and will only run once)
local tools = bp:GetChildren()
for i = 1, #tools do
if tools[i]:IsA("Tool") then -- does not assume that all objects in the backpack will be a tool (2.11.18)
for i = 1, #inputOrder do
local value = inputOrder[i]
if not value["tool"] then -- if the tool slot is free...
value["tool"] = tools[i]
break -- stop searching for a free slot
end
end
end
end
create()
end
function adjust()
for key, value in pairs(inputKeys) do
local tool = value["tool"]
local icon = frame:FindFirstChild(value["txt"])
if tool then
icon.Tool.Image = tool.TextureId
if tool.Parent == char then -- if the tool is equipped...
icon.ImageTransparency = equipped
else
icon.ImageTransparency = unequipped
end
else
icon.Tool.Image = ""
icon.ImageTransparency = unequipped
end
end
end
function onKeyPress(inputObject) -- press keys to equip/unequip
local key = inputObject.KeyCode.Name
local value = inputKeys[key]
if value and uis:GetFocusedTextBox() == nil then -- don't equip/unequip while typing in text box
handleEquip(value["tool"])
end
end
function handleAddition(adding)
if adding:IsA("Tool") then
local new = true
for key, value in pairs(inputKeys) do
local tool = value["tool"]
if tool then
if tool == adding then
new = false
end
end
end
if new then
for i = 1, #inputOrder do
local tool = inputOrder[i]["tool"]
if not tool then -- if the tool slot is free...
inputOrder[i]["tool"] = adding
break
end
end
end
adjust()
end
end
function handleRemoval(removing)
if removing:IsA("Tool") then
if removing.Parent ~= char and removing.Parent ~= bp then
for i = 1, #inputOrder do
if inputOrder[i]["tool"] == removing then
inputOrder[i]["tool"] = nil
break
end
end
end
adjust()
end
end

I’ll rewatch the tutorial later to see if I missed anything, but It’s kinda late today and I’ll have school tomorrow. It would be awesome if you could help me 
(of course the one is a different number each time it’s duplicated.) I’m trying to understand how I could show what each slot has. (So if you have an axe, it’ll show the axe.) I’ve already made the axe picture, however i’m not sure how to actually put it there.
