On respawn add effect

hello, in my code is how add effect to player when respawns but it doesn't work, can anyone help me?

PHP:

    public function onRespawn(PlayerRespawnEvent $event){
        $player = $event->getPlayer();
        $effect = Effect::getEffect(Effect::WEAKNESS);
            $effect->setAmplifier(0);
            $effect->setDuration(10000000);
        if($player->getDeviceOS() == 7){
            $player->addEffect($effect);
        }
    }


Console doesn't say anything

 

You set the amplifier to 0?

 

Possibly something about the device OS check then

 

There is no getDeviceOS function in the player class, this is what you're looking for: https://github.com/pmmp/PocketMine-...network/mcpe/protocol/LoginPacket.php#L51-L52
