BUG: addEffect()

PHP:

public function onEquip(\pocketmine\event\entity\EntityArmorChangeEvent $e){
$p = $e->getEntity();
if(!$p instance of \pocketmine\Player) return;
$p->addEffect(\pocketmine\entity\Effect::getEffect(Effect::SPEED)->setDuration(4000));
}


This does work. But when you rejoin, it gives you an error?

PHP:

Call to....function getValue() on null


(getValue() in \pocketmine\entity\Attribute.php)

I have a feeling that I'm doing it wrong. Even tho it works smooth when the player changes armor or anything whlist fully connected. This error happens only when player joins.

PHP:

use pocketmine\entity\effect;


        $effect = Effect::getEffect(2);  /* Efeect id */
        $effect->setAmplifier(2);    /* Effect Power */
        $effect->setVisible(true);
        $effect->setDuration(10000000000);  /* Effect Time */
        $player->addEffect($effect); /*give player effect */

@JUZEXMOD uh what?

PHP:

!$p instanceof Player 

will always return false as !$p will be false,maybe the effect gets added to other entities too?

This isn't Java where '!' affects next value on right. It means that `!false` and `!(false)` are both the same.

Try to set all Effect attributes - amplifier, visible, duration etc. Use code what @JUZEXMOD provided above, if that doesn't work then it's PocketMine issue.

Yup, PocketMine's issue. But adding a .00001% load (by checking if player has permission) helped me get rid of the console error. This is even more weird...

PHP:

if(!$p instance of \pocketmine\Player) return;
if($p->hasPermission("some.permission") $p->addEffect(\pocketmine\entity\Effect::getEffect(Effect::SPEED)->setDuration(4000));
}


plugin.yml

PHP:

permissions:
  some.permission:
    default: false


By using a permissio plugin (PurePerms), I added that permission to all groups. And now it works.

Setting the permission's default value to true didn't help too. SOO weird.

Perhaps there is some delay? Like you know how the kick message issue...
