[1.16.4] Help How do I create a GUI ?

[Yeah_It_Is]

Hello, so I have started making a mod recently, however I couldn't find any tutorials on how to make a custom "Furnace like" GUI. I found one for the 1.8 but I'm not sure if it woks in 1.16. When I tried to improvise i got nothing other then errors, so I don't really know how to make a GUI. That's why I need help. Does anyone know how to make a GUI like in a furnace or do you have any recent tutorials? Thank you in advance!

GUIs haven't changed much in quite some time.

The only major differences you probably need to be aware of (aside from methods and classes getting new names, eg. GuiScreen -> Screen) is that Slots to handle items still point at vanilla style IInventory rather than Forge's ItemStackHandler capability.

 

But Forge has also supplied a SlotItemHandler (ItemHandlerSlot? I'm looking at my older 1.14 code and that name might've changed too) which accepts an ItemStackHandler and does all the things it needs to to give the proper behavior.
