So basically, I have this item called Seed Satchel, and I want it to be able to have seeds in it, only seeds. When the player has a Seed Satchel, he can press a key, that will open a GUI, then the player can put seeds or take out seeds, then it closes. Thanks!

I am trying to create a shop in my mods for my minecraft server. And I watch a lot of video about it but It was never working and I look at the forge documentation but nothing was working. (I am trying to do somethings similar to this)

I will check that, thanks!

I am Programming a mod and I tried to create a custom Food but all the tutorial that I found are in 1.14 or 1.12. Could someone help me? Thanks!

How can you do that?
