Error Argument 1 passed to pocketmine\Server::getPlayer() must be of the type string, null given,

Erro: http://prnt.sc/e18xc4

Código:
Caso "ir":
$ Player = $ sender-> getPlayer ();
$ Target = $ this-> getServer () -> getPlayer ($ args [0]); - Linha 223
If (! Isset ($ args [0])) {

PHP:

Caso "ir":
                $ Player = $ sender-> getPlayer ();

I cant understand what your saying

 

You're trying to get the player of $sender... $sender is already a player. Just entirely remove that line and change $Player to $sender.

 

Urgh, I just got spacing cancer.

Also please use code blocks:
[PHP]Put php code here[/PHP]
OR for code, that's not php:
[CODE]Your non-php code here[/CODE]

 

Erro? Código?? Caso??? English????

 

Sorry, I'm brasilian and use the translator for this '-'

 

You should learn at least the basics of English. I doubt how much could you do in today's world without English. PHP stands for something that's in English. PHP's built in functions use English words.

Isn't it supposed to be "case" instead of "Caso"? Anyways, fix:

PHP:

$Player = $sender->getPlayer();
if (!isset($args[0])) {
$Sender->sendMessage("§aUse / ir <jogador>");
return;
}
$Target = $this->getServer()->getPlayer($args[0]);
$Player->teletransporte($target);
$Player->sendMessage("§Teleporte concluído!");
$Target->sendTip("§aO ajudante". $Sender->getName(). "Veio para você. \ N \ n \ n \ n \ n");


 

My code in netbeans is right, and "case" in netbeans is "case" don't "caso", but when I put it in the forum, my browser translates automatically. Sorry for this.

 

THX for code

 

No problem. One more thing, assuming you are a beginner to PHP...
PHP $variables are not case sensitive (that is: $Variable is not the same as $variable).

 

Correction: They ARE

 

Are they? Explain me this then..

 

Read it again...

Variables ARE case sensitive
Functions NOT

 

LOL

 

@DanielYTK your problem lies in trying to get the player with $args[0]. You check if $args[0] is set AFTER you execute code with it, while you should FIRST check if $args[0] is set.
