How to make a Compass Tracker

Hello I’m new and made a plugin called Manhunt. There is one problem. I need to make a compass and I have no idea how anyone give me an example of a compass or at least an item that tracks an player.

 

I believe there is already a working and great plugin out by korado531m7 that does just this. https://poggit.pmmp.io/p/NearestPlayerCompass/

 

That plugin crashes the server in use. Perhaps can show you the error and someone fix it or just find a another.

 

I tried using the that plugin but with the latest dev and gives me this error idk if anyone can fix this . It says undefined property on line 41 which is in here.

PHP:

private function sendEachType(Player $player, string $message){
        switch(strtolower($this->getConfig()->get('sending-message-type'))){
            case 'tip':
                $player->sendTip($message);
            break;
            
            case 'popup':
                $player->sendPopup($message);
            break;
            
            default:
                $player->sendMessage($message);
            break;
        }
    }
    
    private function setSpawnPositionPacket(Player $player, Vector3 $pos) : void{
        $pk = new SetSpawnPositionPacket();
        $pk->x = $pos->getFloorX();
        $pk->y = $pos->getFloorY();
        $pk->z = $pos->getFloorZ();
        $pk->x2 = $pos->getFloorX();
        $pk->y2 = $pos->getFloorY();
        $pk->z2 = $pos->getFloorZ();
        $pk->dimension = DimensionIds::OVERWORLD;
        $pk->spawnType = SetSpawnPositionPacket::TYPE_WORLD_SPAWN;
        $player->dataPacket($pk);
    }
