[1.12.2] Getting Loaded Chunks from Client Side

[unassigned]

Hello, I have some rendering I'd like to do in some chunks. Basically, I have a capability attached to the world (more specifically each chunk), that can hold a certain value, once a value threshold is hit, I'd like to do some type of rendering. However, I'm having issues getting the chunks from the client. I'm currently using:

                Iterator<Chunk> loadedChunks = event.world.getPersistentChunkIterable(((WorldServer) event.world).getPlayerChunkMap().getChunkIterator());

which I access through WorldServer.

 

Is there any way to get the chunks?

 

Thanks.

I solved this problem before. This was my code:

 

Long2ObjectMap<Chunk> map;
try {
    Field chunkMapping = ChunkProviderClient.class.getDeclaredField("chunkMapping");
    chunkMapping.setAccessible(true);
    map = (Long2ObjectMap<Chunk>) chunkMapping.get(world.getChunkProvider());
} catch(Exception e) {
    return;
}

You should really cache that Field object (at mod startup time - preinit is fine), especially if that code gets run frequently.  Reflection isn't the fastest thing in the world.
