Effects on join

Can someone help me with this?

PHP:

<?php

namespace Effectsplugin;

use pocketmine\Server;
use pocketmine\Player;

use pocketmine\entity\Effect;

use pocketmine\plugin\PluginBase;

use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\ConsoleCommandSender;

use pocketmine\event\Listener;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerRespawnEvent;   

class main extends PluginBase implements Listener {

    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this,$this);
        $this->getLogger()->info("Plugin Enabled");
    }

    public function onPlayerJoin(PlayerJoinEvent $event){
        $player = $event->getPlayer();
        $effect = Effect::getEffect(Effect::NIGHT_VISION);
        $effect->setDuration(99999);
        $effect->setAmplifier(1);
        $effect->setVisible(false);
        $player->addEffect($effect);
    }
}

 

$player->addEffect(new EffectInstance($effect));

 

nothing happens

 

import EffectInstance?

 

Use this:

PHP:

use pocketmine\Server;
use pocketmine\Player;

use pocketmine\entity\{Effect, EffectInstance};

use pocketmine\plugin\PluginBase;

use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\ConsoleCommandSender;

use pocketmine\event\Listener;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerRespawnEvent;   

class main extends PluginBase implements Listener {

    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this,$this);
        $this->getLogger()->info("Plugin Enabled");
    }

    public function onPlayerJoin(PlayerJoinEvent $event){
        $player = $event->getPlayer();
        $player->addEffect(new EffectInstance(Effect::getEffect(Effect::NIGHT_VISION), (99999*20), (1), (false)));
    }
}

PHP:

<?php

use pocketmine\entity\EffectInstance;

use pocketmine\plugin\PluginBase;

use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\ConsoleCommandSender;

use pocketmine\event\Listener;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerRespawnEvent;   

class main extends PluginBase implements Listener {

    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this,$this);
        $this->getLogger()->info("Plugin Enabled");
    }

    public function onPlayerJoin(PlayerJoinEvent $event){
        $player = $event->getPlayer();
        $effect = Effect::getEffect((int) 16);
        $duration = 9999999;
        $amplification = 2;
        $visible = false;
        $instance = new EffectInstance($effect, $duration, $amplification, $visible);
        $player->addEffect($instance);
    }

    public function onPlayerRespawn(PlayerRespawnEvent $event){
        $player = $event->getPlayer();
        $effect = Effect::getEffect((int) 16);
        $duration = 9999999;
        $amplification = 2;
        $visible = false;
        $instance = new EffectInstance($effect, $duration, $amplification, $visible);
        $player->addEffect($instance);
    }
}

 

try adding a few ticks of delay to it

 

im still new in coding sorry but can you make it or just a pattern i can follow cause i really cant make it

 

PHP:

        $this->plugin->getScheduler()->scheduleDelayedTask(new ClosureTask(function (?int $currentTick) use($player, $instance): void{
           $player->addEffect($instance);
        }), 5);
