Check block

Hello?

 

PHP:

/** @var $sign Sign */
/** @var $player Player */
/** @var $block Block */
$block = $sign->getLevel()->getBlock($sign->add($player->getDirection()->normalize()));


Behind, relative to what?

 

You're checking if an object is zero, just like the error says. You should use ...->getId().

 

I know, I understood you wrongly.

 

I think you could try getting the meta of the sign, as it should be different for the direction it is facing. Then make a switch case for those sides and make it $z + 1 or $x - 1 for example.

You can use the code from here

 

$block->getSide() will give you object Block

 

The link there is your example? Just replace $this inside there with $block, a Block object
Note: dont just copy the whole function and expect it to work, copy only what you need

 

$block is your sign's block

 

PHP:

#$b need to be instanceof Block
$faces = [
   2 => 3,
   3 => 2,
   4 => 5,
   5 => 4,
  ];
   if(isset($faces[$b->getDamage()])){
    if($b->getSide($faces[$b->getDamage()])->getId() === $someBlockID){

$this->owner->getServer()->getDefaultLevel()->setBlock($b, Block::get(1,0));
}

}

 

PHP:

#$b need to be instanceof Block
$faces = [
   2 => 3,
   3 => 2,
   4 => 5,
   5 => 4,
  ];
   if(isset($faces[$b->getDamage()])){
    if($b->getSide($faces[$b->getDamage()])->getId() === $someBlockID){

$this->owner->getServer()->getDefaultLevel()->setBlock($b->getSide($faces[$b->getDamage()]), Block::get(1,0));
}

}
