The revised version features a more Modernized & Cartoonish look. The “Trade Buttons” features a much-more vibrant and larger look. And finally the UI has been sorted into neat folders for scripting and appearance sake.
If you are intrested in using this UI, I ask that you never claim it as your own, or sell it. Credit is appreciated, however NOT needed (It’s just a way to say “Thank you”).
There isn’t “both”, there are hundreds of different ways to make an inventory. You need to make your own by yourself, or it doesn’t really help your scripting skill.
just learn, have patience. you’ll learn as you do whatever way works for you when you’re learning how to script in ROBLOX. you can even look up a YT tutorial and i probably guarantee there’s some of it up there.
Learn image ids or viewport frame manipulation for item icons (optional)
If you can do all that, you can make an inventory system without help. If you don’t, just learn. Don’t ask someone to just teach the whole inventory system.
if they don’t work, just look up the pieces of what a trading system has, like whatever PoisonousSoapBar said, look those up in the ROBLOX Developer Hub (Roblox Creator Documentation), or watch a guide about them.
