ChunkDataPacket

Hello, I am creating a plugin that includes sending chunks to only one player. After searching up the ChunkDataPacket on GitHub, I don't understand how the $packet->data is written. I only know that it is a string, but I can't understand what it is composed of, what a minichunk is, and how the blocks are listed. Please help!

Really so many people read can't anyone help?

Well, ask shoghicp or see the src code of PocketMine

Nobody (at least not me) really understands the chunk format. MinecraftWiki doesn't explain it well enough.

Look at the src? I clearly told that I didn't understand the src above...

I know that, but I don't understand the mini chunks format and how they are combined. Looks like combining mini chunks with something called $Yndex ..

Then what do you send when you teleport a player to another world?

I know that, and I would like to know the structure of a chunk that you "gets the data directly from the level class".

I know... And what I have been saying all the time is that I don't understand that method(s)...
