Saving entity fields and NBT

[InspectorCaracal]

Okay, straight to the point.

How do I convert a block reference to NBT for saving an entity? e.g. a field named "flower" set to Blocks.ROSE_BUSH

You can call IForgeRegistryEntry.getRegistryName.toString() and save it to the nbt, to read it you can use ForgeRegistries.BLOCKS.getValue(new ResourceLocation(nbt.getString("saved_block"))) something like that.

Ah! Perfect! I'll take a look at those functions, they look like exactly what I was trying to dig up.

Ultimately this wound up with the field being an Item instead of a Block but I'm running into a small bump again here. After saving and reloading the world, the field seems to be returning "air" instead of the item it's supposed to be. It seems to be because I'm using custom items and the string-to-item conversion is assuming the 'minecraft' namespace, but I can't figure out how to do the item-to-string with the namespace included.

This is what I have right now:

public void load(BlockState state, CompoundNBT nbt) {
	super.load(state, nbt);
	this.honeyType = null;

	String saved_honey = nbt.getString("Honey");
	this.honeyType = ForgeRegistries.ITEMS.getValue(new ResourceLocation(saved_honey));
}

public CompoundNBT save(CompoundNBT nbt) {
	super.save(nbt);
	nbt.putString("Honey", this.honeyType.toString());

	return nbt;
}

You have to call honeyType.getRegistryName().toString() to receive something like "mymod:honey_block", otherwise you will get "honey_block" that Minecraft will automatically put the prefix "minecraft:" in front of it, which does not exist.

Ahhhh, got it. That's what I get for going and doing my own thing haha
