inventory gui? (reference image)

first of all i tried some scripts they did not work so i deleted them so i can not show any scripts.

the top bar is a kind of hotbar the box under that is like a backpack

is there anyone that can help me with an inventory script that if you click like a weapon the weapon goes into your inventory

the weapon has clickdetector but can i do that with a localscript?

and how do i do something that if i have something in my inventory that i can drag into the hotbar i think

Slot1 = script.Parent.Frame.Slot1
player = game.Players.LocalPlayer
mouse = player:GetMouse()

Slot1.Position = mouse.Target

(i have not tried this)

but how do you get it that the icon keeps the slot you dragged it to?

if there is anything missing comment.

What you need to do is use Clone() Which will allow you to clone the Weapon from where ever you are storing it and move it to either backpack, so they can access it, or into there character which will make then hold it after it is cloned.
