How would I be able to create a crafting GUI. Here’s How I would like it, You would have a key to open the GUI like, “C” So they press it and it shows all the crafting recipes but you have to have the items so like a stone Pickaxe, 3 stone and 1 wood. But if they don’t have that, it will say on the screen, “Collect Items To Craft” But if they do It will pop up in their inventory, I would also like a blueprint for Inventory that can drop items. Also a blueprint for like trees so when they punch it will give them “Wood” and I think it would be easier just to give me a blueprint download from like mediafire dropbox or somthing like those cites anyway thanks for reading please HELP!

Request like this should normally be followed by how much you are willing to pay for someone to make your game for you…
Otherwise, for every little feature you want to add you are going to have to research and figure out how to do it piece by piece.
