Help Generating Trees in 1.10.2

[Poseidon5001]

Hi everyone. I was attempting to generate trees in the overworld, but I seem to have had little success.
Just wanted to see where I went wrong.
Thanks

Updated code

You are putting chunkX and chunkY directly to the position. It should be x and y, isn't it?

Oh, you're right. Thank you! Hopefully that's the only thing that's wrong.

 

EDIT: Still doesnt seem to be working. I also updated the code embedded in the main post

I think you should do the same with biomePos(for World::getBiome), If I recall correctly the position is not the chunk coordinates, but positions of each block.

It works! Thank you!
