Heyo! To expand a little bit, I have had an idea, I just am not really sure to where to start, so some help would be great. Idea: So, you know how the Minecraft recipe book has a button? Maybe using the code like that, but instead of opening a little recipe menu, it overlays a second gui, connecting to the same blockstate and accessing a new set of input and result crafting. So, you'd have both, for example, the furnace and the crafting table, and you'd flick between them. Issue is, I have no Idea how buttons are supposed to work in Minecraft, and I don't really know how to find the source code for the crafting table, so that locks me at a dead end right at the beginning. Unless this is some Java skill issue on my part, I'm mainly a C++ dev. Anything, even a, "you're just stupid", would be great, as it would point me in the direction of more general Java googling instead of just Forge

Alright, so this might be a Java problem, and if it is I'm sorry, but either I'm missing something super obvious or I don't have the right libraries installed This is my item initialization file, and I'm simply trying to initialize an item using the RegisterEvent and IntelliJ refuses to acknowledge it as a real class and I am running out of things to google as I simply cannot find an answer to my issues. Here's my code package com.GitHub.BeaniePope.ThaumoNuclear.init; import net.minecraft.item.Item; import net.minecraft.util.ResourceLocation; import net.minecraftforge.fml.common.eventhandler.SubscribeEvent; import net.minecraftforge.fml.common.registry.ForgeRegistries; import static com.GitHub.BeaniePope.ThaumoNuclear.ThaumoNuclear.MODID; public class itemInit { @SubscribeEvent public void register(RegisterEvent event) { event.register(ForgeRegistries.Keys.ITEMS, helper -> { helper.register(new ResourceLocation(MODID, "gay"), new Item()); } ); } } Essentially the event.register and RegisterEvent events refuse to exist anywhere in any import and I do not know why, so any help would be nice Again, I completely understand if this is a Java issue and thus not for this forum but I'm not actually sure if it is so just tell me and I'll try my best. Thank you.
