And code:

PHP:

public function warpAs(CommandSender $sender, Player $p){
if($this->canUse($sender)){$p->teleport($this->p);
        $effect = Effect::getEffect(1); //Effect ID
        $effect->setVisible(true); //Effect particles
        $effect->setDuration(300); //Duration in ticks
        $p->addEffect($effect);
        $p->sendMessage("§4§l>");
        $p->sendMessage("§4§l> §aHaz sido teletransportado a §3" . $this->name);
        $p->sendMessage("§4§l>");
        $p->sendPopup("§l§bBienvenido a §l§c" . $this->name);

Not Work

I make plugin with this code and it work greatly!
Server make CrashDump?

Omg... I wrote it? I wrote

PHP:

pocketmine\entity\Effect;

oh, really i forgot that xD
thank you

Lol, try it, it should works.

it work in my Plugin Test Server, but no in my big server :c

Its bad :C
What errors?

dont give me any error log, only the effects do no appear

Hmmm...

In my windows server (for plugin test): it works
In my linux server (PVP and Minigames): it not work

Maybe, than in your linux servers somethings like plugins can disturb the addEffect() ...
Is there a plugin that uses pocketmine\entity\Effect ?

Mmm... Maybe, and Yes, uses the class pocketmine\entity\Effect

Are you sure that in your Linux server, in the code for the command is there :

PHP:

public function warpAs (Command Sender $sender, Player $p) {
// Effect codes
}

Because, if there's not Player $p it won't work! If use it on :

PHP:

if($this->canUse($sender)){$p->teleport($this->p);
        $effect = Effect::getEffect(1); //Effect ID
        $effect->setVisible(true); //Effect particles
        $effect->setDuration(300); //Duration in ticks
        $p->addEffect($effect);
        $p->sendMessage("§4§l>");
        $p->sendMessage("§4§l> §aHaz sido teletransportado a §3" . $this->name);
        $p->sendMessage("§4§l>");
        $p->sendPopup("§l§bBienvenido a §l§c" . $this->name)

Like, if it works!

like, thank you

Thanks you, but here i don't understand, did it works ?
