Solved Boost signs

Hi.
First I have some code

PHP:

//PlayerMoveEvent is $e

$player = $e->getPlayer();
foreach($player->getBlocksAround() as $b) {
if($b == Block::get(Block::SIGN)) {
$player->knockback(/*???*/);
}
}



But this isn't working. I want to boost the player away from the sign. With this code the sign is only detected if the player is over it.

 

use AxisAlignedBB to check if player is in front of sign.

 

Mh. Can you give me an example?

 

PHP:

$level = /*Your level*/
$tile = $level->getTiles();
foreach ($tile as $sign){
if($sign instanceof Sign){ // pocketmine tile sign not block
foreach($level->getNearbyEntities(new AxisAlignedBB($sign->x - 10, $sign->y - 10, $sign->z - 10, $sign->x + 10, $sign->y + 10, $sign->z + 10)) as $ent){
if($ent instanceof Player){
//knockback entity
