How to disable flying in survival?

Hey everyone, I've encountered an issue with my server, my players that are in survival are able to fly. I have no idea if this is due to a plugin allowing it or something in the server files. How do I change this?

 

I think can it work

PHP:

use pocketmine\event\player\PlayerMoveEvent;

public function onMove(PlayerMoveEvent $ev){
  $p = $ev->getPlayer();
if($p->getGamemode() === 0){
 $p->setAllowFight(false);
}
}

 

Alright cool, but where do I put this? In a file?

 

PHP:

<?php

namespace Yournamespace;

use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\evenr\player\PlayerMoveEvent;
use pocketmine\Player;
use pocketmine\Server
class YourClass extends PluginBase implements Listener{
      public function onEnable (){
      $this->getServer()->getPluginManager()->registerEvents($this, $this);
    }
public  function onMove(PlayerMoveEvent $ev){
  $p = $ev->getPlayer();
if($p->getGamemode() === 0){
 $p->setAllowFight(false);
    }
  }
}


 

Dude, he's not a programmer don't you see it's the Help thread? Also what does your answer have to do with what he asked? You're just giving useless code.

There is probably a plugin allowing them to. Check running the server without any plugins and see what happens.

 

Alright I will try that. Thanks for the advice

 

Ok so I went through all my plugins, removing them and putting them back in and seeing if they allowed it and the one that did it is Festival. I had plans to use that plugin to build out PVP zones and non PVP zones but I'm not going to use it until they fix this flying in survival issue.
