ItemStack became non-nullable (and got the EMPTY constant as well as the count methods) in 1.11 afaik. Any particular reason you are modding for 1.10.2? You should update to the latest (1.12.2) version.

can I update to the 1.12.2 without reprogramming everything?

For the most part, as long as you are using the suggested ways of doing things (read: capabilities and registry events). You will have to fix a few things here and there but it should be fairly straightforward, there aren't many changes between 1.10.2 and 1.12.2 codebase-wise.

I want to make a gui but this video is the only video I found to make a custom GUI.
