What is wrong with this code?

I have been working on a plugin and it doesn't work (obviously). I have tried to fix it several times but to no avail. Here is the code:

PHP:

<?php

namespace Hittmana\VipGate;
use pocketmine\command\CommandSender;
use pocketmine\command\Command;
use pocketmine\plugin\PluginBase;
use pocketmine\Player;
use pocketmine\event\Listener;
use pocketmine\event\player\PlayerMoveEvent;

class MainClass extends PluginBase implements Listener
{
  public function onEnable()
        {
        $this->getLogger()->info("VipGate enabled v1.0.0");
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        }
    public function onDisable()
        {
        $this->getLogger()->info("VipGate disabled v1.0.0");
        }  
    public function onMove(PlayerMoveEvent $event)
        {
        $player = $event->getPlayer();
        $block = $player->getLevel()->getBlock($player->floor()->subtract(0, 1));
        if ($block == "activator_rail" or $block == "126")
            {
                $event->getPlayer()->teleport($this->getServer()->getLevelByName()->getSafeSpawn());
            }
        }
    }   

And here is the error:

Code:

Could not pass event 'pocketmine\event\player\PlayerMoveEvent' to 'VipGate v1.0.0': Method pocketmine\block\ActivatorRail::__toString() must return a string value on Hittmana\VipGate\MainClass

Please help!

The method getBlock on your PlayerMoveEvent handler returns an object, not an integer or a string. You should use getId method if you want check block's ID.

Thanks! I will try this.

I changed it to

PHP:

$block = $player->getLevel()->getId($player->floor()->subtract(0, 1));

And now it does nothing, it doesn't even send anything to the console.

Anyone?

Block->getId()

Where?

First, you need to get the block first:

PHP:

$block = $player->getLevel()->getBlock(new Vector3($player->getFloorX(), $player->getFloorY() - 1, $player->getFloorZ()));


Then, check if id = 126:

PHP:

$block = $player->getLevel()->getBlock(new Vector3($player->getFloorX(), $player->getFloorY() - 1, $player->getFloorZ()));
if($block->getId() == 126){

}


Last, tp player to level:

PHP:

$block = $player->getLevel()->getBlock(new Vector3($player->getFloorX(), $player->getFloorY() - 1, $player->getFloorZ()));
if($block->getId() == 126){
     $player->teleport($this->getServer()->getLevelByName("Name")->getSafeSpawn());
}


You have to use /pocketmine/math/Vector3

Ohhh Ok thanks!
