I haven't messed with it, I only know that it exists.

It depends on the use-case

Yeah, your registration line was fine, all you had to do was change the signature of decode.

This is wrong. You will never receive a packet instance as a parameter here because your job is to create it. https://github.com/Draco18s/ReasonableRealism/blob/1.14.4/src/main/java/com/draco18s/industry/network/ToServerFilterClick.java#L38-L47

ChestTileEntityRenderer

or use ifPresent

That's furnace fuel stuff.

By "won't break" do you mean that the break speed is the same as a fist, or that the block is not dropped (aka "harvested")?

You're trying to use the vanilla crafting GUI. The vanilla crafting gui checks to see if the block being accessed is The One And Only Vanilla Crafting Table. Your block is not The One And Only Vanilla Crafting Table. Therefor the use of that gui is invalid and thus closed.

I didn't realize these methods existed. 👍

You need a custom ItemEntity to accomplish that. Then you need to detect ItemEntities joining the world, check that their item is your item (and not your custom ItemEntity), and replace it.

I mean, if you paid money to access this forum, you might want to report that. Because this forum is free.

Ore Gen is json based now.

Because the code it exports when not doing custom code things is garbage. And because its generated by MCreator not Forge nor the user, its pointless trying to fix it.

By the way:

Well yes, but no. They don't have to delete stuff, they can just make a new zip file that has the same folder structure and files names and override your stuff without ever touching it. That's....kinda the whole point of the json system.

Because that's the default Vanilla gui texture size.

Either you can force enchantments onto the item, or you can use Global Loot Modifiers.

See these lines? That's how you add stuff. The items and amounts in question are initialized by values stored in the json:

Your DeerEntity(EntityType<? extends DeerEntity> type, World worldIn) is protected, it should be public. I'm also pretty sure it needs to be DeerEntity(EntityType<T> type, World worldIn) as indicated by the error.

No, attach the capability to the item stack.

LazyOptional is just a lazily-instantiated Optional. It still holds a value, that value is of type T. T as in LazyOptional<T> That value gets cast to T when you call someLazy.cast(), so if the value actually stored in the LazyOptional is not actually of type T, the cast will fail. Optionals are just a box wrapped around a concrete object because you don't know if that object actually exists or not (which is why you have to use ifPresent, orElse, or orElseThrow--depending on circumstances).

There's already a collection that contains all the items in the game, its called the "item registry" and Forge tracks them.
