I have a chunk capability that stores an energy value for each chunk. The Capability.IStorage implementation calls ChunkEnergy#setEnergy when reading from NBT, this in turn calls ChunkEnergy#onEnergyChanged which sends a packet to update all clients tracking the chunk with the new energy value.

 

In 1.12.2, I used World#isBlockLoaded before getting the Chunk from the World to prevent an infinite recursion scenario where loading the chunk attempts to load the chunk.

 

In 1.14.4, I'm using IWorld#chunkExists instead; but this returns true even when the chunk is being loaded. If I then call World#getChunk while the chunk is being loaded, this seems to result in a deadlock where the chunk loading never completes and the world never loads.

 

The code on GitHub currently uses world.getChunk(x, z), but I've tried calling world.getChunk(x, z, ChunkStatus.EMPTY, false) just to see if it will return null or an empty chunk and this results in the same deadlock.

 

It seems like I could use ChunkHolder#func_219299_i and ChunkHolder#func_219278_b to get the ChunkStatus of a chunk, but there don't seem to be any public methods to get a ChunkHolder and I'm reluctant to use internal APIs if there are public APIs available.

 

Does anyone know if there's a way to determine whether a chunk is fully loaded without causing a deadlock if called during chunk loading?

Would World#getChunkProvider().isChunkLoaded(BlockPos/ChunkPos) work for this?

Thanks, that worked perfectly.
