Solved How to give player effect and if it dies. the effect will not reset

Hmmm.

 

reapply the effect again

 

you can use that it will help you

PHP:

public function onRespawn(PlayerRespawnEvent $event){
   $player = $event->getPlayer();
   $effect = Effect::getEffect(8);  //Effect::getEffect(effect id);
   $player->addEffect(new EffectInstance($effect, 999, 1)); 
}

 

more simply, remove this code every time respawn $player->removeAllEffects(); but has risks
