How would I make a client side modification that changes the backpack gui?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    Change the backpack gui icons back to 2013
  2. What is the issue? Include screenshots / videos if possible!
    I don’t know if it’s done by Code(which I assume it is) or GUI icons, or how I would change it if its done by code.
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    Looked through ALL the files.

Idk what you mean by

If its something that you want to change in a certain point while playing the game then it have to be done by coding it.

That being said, to code it you will have to gave more info of where the backpack gui icons is in the workspace and when you want it to change.

game.StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)

This would disable the Backpack Gui to being with.

I’m trying to make a client sided modification to the roblox client that changes the roblox backpack buttons(the one for the tools you equip) back to how they were in 2013
