What is the wrong thing in this script?
No errors dumped at console/LOG files. Runs perfectly except ....... this function does nothing.

Code:

public function init(){
            $this->api->addHandler("player.block.place",array($this,"blockPlace"));
########
}
########
    public function blockPlace(&$data,$event){
        $player=$data["player"];
        $level=$player->entity->level;
        if ($level->getName()==="lobby2" and $this->syncOn($player->username)===true) {
            $oB=$data["target"];
            $vT=new Vector3($oB->x,$oB->y,$oB->z);
            $block=$level->getBlock(new Vector3($oB->x,$oB->y,$oB->z));
            $vX=new Vector3(255-$block->x,$block->y,$block->z);
            $vXZ=new Vector3($block->x,$block->y,255-$block->z);
            $vZ=new Vector3(255-$block->x,$block->y,255-$block->z);
            $level->setBlockRaw($vX,$block);
            $level->setBlockRaw($vXZ,$block);
            $level->setBlockRaw($vZ,$block);
        }
    }

Um, does it have something to do with the random "&" in the function?

Also known as a reference.

Oh shit, I just realised how old this is...

I know that now. XD
