[1.8.9] Chunk IDs

[Atijaf]

Do chunks have an ID associated with them, or just the x,z coords? 

I need to store information into a list about a block that exists inside a certain chunk.  Hard to explain...

 

I am saving data to the world and would only like to access NBT data if needed.  That's where the chunk ID would come to play.  I would check to see if NBT has a tag associated with the ID of the chunk so that I may load it's data into memory.

 

If there is no such thing as a chunk ID, what are some alternatives I can do?

 

Thank you!

The only unique identifier of a chunk is its x and z coordinates.

[Atijaf]

Perhaps I can use the chunk's hashCode to obtain a unique Identifier?

 

Or... I can make a matches method that compares the x and z coords and return true if... Yeah..

 

Would you happen to know the max and min x and z position of chunks?

[Choonster]

Chunk#getChunkCoordIntPair

returns the chunk's coordinates as a

ChunkCoordIntPair

. This class implements

Object#hashCode

to return a hash based on the coordinates.

 

You can also use the

ChunkCoordIntPair#chunkXZ2Int

method to combine the x and z coordinates of a chunk into a

long

suitable for hashing.
