Add NBTTag for Block

[TheMinecraftBox]

Hello, I'm here because I would like to create more information for every block. I successful to add a nbt but it's juste for one block and for evry world...

How can I add a NBTTag for every block placed and for one world and not just one NBT for one block and for every world?
I would like use the same system that TileEntities, Entities or ItemStack.

(I can't use the TileEntity because I want add this NBTTag for every vanilla Blocks).

I'm use the Events: PlaceEvent, HarvestDropsEvent, BreakEvent, ChunkDataEvent.Save and ChunkDataEvent.Load.

Thank you for write me!

AFAIK you don't.

 

There might be ways that can potentially achieve this, but are probably discouraged.

What are you trying to achieve? There is probably a better way of doing it.

Okay, I would like that when the player place a enchanted block in the world, the game save the enchantment when the block is broken.

With my NBT on my event class, it work but juste for one block. If the player place two blocks with this nbt, there are juste one block with this NBT.

What would your feature look like from an end-user perspective? There are multiple ways of doing stuff like this

Sounds like you're storing the data in a field of your block class.

This will never work (as you've seen) because blocks are singletons.

 

You must use a separate data structure, such as a Tile Entity.

Use a tile entity instead.

Since blocks are singleton; values in your block class will be the same for every block in the world.

You can either have a block with a TE that takes on the model of the "enchanted" block or have a chunk capability that holds the additional data in a <BlockPos, YourData> map.

Create a TileEntity and how can I add all blocks Minecraft (in one file if it's possible). Or else, how I can create a NBT with singletons?

If it's so hard, I can make one file for one block but it's will so longers...

Singleton is the name of a pattern whereby there is only one object and it is referenced everywhere as needed. 

 

"Per block" is the "everywhere"

 

If a TE won't work for you, you need a custom data studies that holds that information by coordinate. You will need to manage it yourself. It will be hard. 

 

You have no other options.
