Solved How to randomize blocks

Im want to make a BlockParty plugin, but one i dont know how to make a random blocks that fills up an area?

 

Blocks all use different ID numbers, so you could use the PHP mt_rand function to produce a random ID, like this:

PHP:

 $randomId = rand(1, 255); 
 $level->setBlockIdAt($x, $y, $z, $randomId);

You'll have to figure out your coordinates and level yourself. Either hardcode it, use a config, or even randomize that.

 

Thank you for your help!
