GUIs are easy to make, but to make them interactive requires basic scripting knowledge. It is highly recommended you read some tutorials on scripting in ROBLOX Lua before you read about GUIs, as they are pretty advanced. However if this did not discourage you, then I wish you luck in your quest to master GUIs! You should have the Explorer window and the Properties window open at all times when working with GUIs. * To open the Explorer window, go to View > Explorer. * To open the Properties window, go to View > Properties.
