Solved Spawn protection

I want to protect every block in a 12-metre radius from a team spawn point. I currently have the following code:

PHP:

        public function onBlockBreak(BlockBreakEvent $event){
        $player = $event->getPlayer();
        $mapa = $player->getLevel()->getFolderName();
        if(in_array($mapa,$this->arena)){
            $config = new Config($this->getDataFolder() . "/config.yml", Config::YAML);
            $level = $this->getServer()->getLevelByName($mapa);
                            if($this->checkTeam($player) == "blue"){
                $team = "blue";
                                $thespawn = $config->get($mapa . "SpawnBLUE");
                                $x = $event->getBlock()->getX();
                                $z = $event->getBlock()->getZ();
                                if (($x<$thespawn[0]+12) || ($x<$thespawn[0]-12) || ($z<$thespawn[2]+12) || ($z<$thespawn[2]-12)){
                                    $event->setCancelled(true);                
                                }                   
               }elseif($this->checkTeam($player) == "red"){
                $team = "red";
                                $thespawn = $config->get($mapa . "SpawnRED");               
                                $x = $event->getBlock()->getX();
                                $z = $event->getBlock()->getZ();
                                if (($x<$thespawn[0]+12) || ($x<$thespawn[0]-12) || ($z<$thespawn[2]+12) || ($z<$thespawn[2]-12)){
                                    $event->setCancelled(true);
                                }                   
                            }
        }
    }
   
    public function onBlockPlace(BlockPlaceEvent $event){
        $player = $event->getPlayer();
        $namemap = $player->getLevel()->getFolderName();
        if(in_array($namemap,$this->arena)){
                    $config = new Config($this->getDataFolder() . "/config.yml", Config::YAML);
                    $level = $this->getServer()->getLevelByName($namemap);
                            if($this->checkTeam($player) == "blue"){
                $team = "blue";
                                $thespawn = $config->get($namemap . "SpawnBLUE");
                                $x = $event->getBlock()->getX();
                                $z = $event->getBlock()->getZ();
                                if (($x<$thespawn[0]+12) || ($x<$thespawn[0]-12) || ($z<$thespawn[2]+12) || ($z<$thespawn[2]-12)){
                                    $event->setCancelled(true);                
                                }                   
               }elseif($this->checkTeam($player) == "red"){
                $team = "red";
                                $thespawn = $config->get($namemap . "SpawnRED");               
                                $x = $event->getBlock()->getX();
                                $z = $event->getBlock()->getZ();
                                if (($x<$thespawn[0]+12) || ($x<$thespawn[0]-12) || ($z<$thespawn[2]+12) || ($z<$thespawn[2]-12)){
                                    $event->setCancelled(true);
                                }                   
                            }
        }
    }


I'm still confused about the math involved. Can anybody help me out?

 

If you want to cancel it within a radius, you're better off using distance() or distanceSquared()

PHP:

if($event->getBlock()->distance($position) <= 12) {
  $event->setCancelled();
}

 

Working fine now that I use this code:

PHP:

$spawn = new Position($thespawn[0],$thespawn[1],$thespawn[2],$level);
if($event->getBlock()->distance($spawn) <= 12) {
    $event->setCancelled(true);                
}


Thanks @Sandertv!

 

No problem! Glad it works.
