Please do

#44

you could just change what is in the frame

#45

Also I cant give you my code because roblox studio is bugging out rn and it wont let me access places from other games. The entire asset manager just does not seem to work today

#46

oh, so what should we do?

#47

You should try to learn more about how to make systems like this. Watch some tutorials and see how they do things. Then try to make your own system

#48

Do you know any good YouTube tutorials or something?

#50

Is it possible to see the code now?

#51

Sure, but rn I am unsure how to put it in a code box on the dev forums

#52

what do you mean? Can you just put when you update /save the gui?

local function LoadSlot(ItemSlot, SlotFrameData)
	--Setting Variables
	local ItemName = ItemSlot.ItemName
	local IsEmpty = ItemName == ""
	local SlotItemData = Items[ItemName]
	
	local ItemFrame = SlotFrameData.Gui.ItemFrame
	local OldModel = ItemFrame.VP.Camera:FindFirstChild("Model")
	
	--Setting ViewportFrame Model
	if SlotFrameData.ItemName ~= ItemName then
		SlotFrameData.ItemName = ItemName
		
		--Getting Rid of Old Model
		if OldModel then
			OldModel:Destroy()
		end
		
		--Creating new Model
		if not IsEmpty then
			local newModel = SlotItemData.Model:Clone()
			newModel:SetPrimaryPartCFrame(CFrame.fromOrientation(0, 45, 0))
			newModel.Parent = ItemFrame.VP.Camera

	--Setting QuanitityLabel
	local ItemQuantity = ItemSlot.Quantity
	if not IsEmpty and SlotItemData.Stackable then

			ItemFrame.Quantity.Text = ItemQuantity

		end
	else

This is the function that I call to update all the slots

#58

would this be fired by a remote event? or stay inside of the local script?

#59

I have a function that tells the client when their data has been changed so my code listens to that and calls this function when it does

local function UpdateInventory()
	for i, v in pairs(PlayerData.SlotData.Inventory) do
		LoadSlot(
			PlayerData.SlotData.Inventory[i],
			InventorySlotFrameData[i]
		)
	end
	for i, v in pairs(PlayerData.SlotData.HotBar) do
		LoadSlot(
			PlayerData.SlotData.HotBar[i],
			HotBarSlotFrameData[i]
		)
	end
end
#60

and what is the old model thing?

#61

To display the item my code uses a viewport frame. When we want to change which item it is displaying we first have to get rid of the old one

#62

He is resetting the slots so if there is anything in the old inventory slots he wants to get rid of it.
