[NEW API] How to break/place a block with given coords

OK so how do I break a block with
$x,$y,$z and $level also how to place a block with xyz and level

Please READ the pocketmine API, it's really simple, or take a look at https://docs.pockemtine.net, you're spamming with tons of questions that you can resolve by yourself, please make a RESEARCH, not a search.

Hint: src/pocketmine/level/Level.php

Search.

Edit: And with the betas released, you don't need to tag your threads with [NEW API] anymore.

OK thx (I saw someone using old api I wasn't sure now I am)

Research

Lol
