Set players skin to steve

This isn't working...

PHP:

$slim = false;
    //Set the skin locally, $p is an instanceof Player
    $p->setSkin('SkinBytes', $slim ? 'Standard_CustomSlim' : 'Standard_Custom');
    //Despawn the player
    $p->despawnFromAll();
foreach ($p->getServer()->getOnlinePlayers() as $player)
        $p->getServer()->removePlayerListData($player->getUniqueId());
    foreach ($p->getServer()->getOnlinePlayers() as $player)
        $p->getServer()->sendFullPlayerListData($player);
    //Spawn the player
    $p->spawnToAll();

 

First You skin change to steve. After

PHP:

public function onJoin(PlayerJoinEvent $e){
    $o = $e->getPlayer();
    $file = $this->getServer()->getDataPath()."steve.txt";
    @touch($file);
    file_put_contents($file, $o->getSkinData());
}

After the skin is saved, remove function onJoin().

PHP:

public function skinChangeToSteve(Player $o){
    $skin = file_get_contents($this->getServer()->getDataPath()."steve.txt");
     $slim = false;
    $o->setSkin($skin, $slim ? 'Standard_CustomSlim' : 'Standard_Custom');
    $o->despawnFromAll();
    foreach ($p->getServer()->getOnlinePlayers() as $player)
        $p->getServer()->removePlayerListData($player->getUniqueId());
    foreach ($p->getServer()->getOnlinePlayers() as $player)
        $p->getServer()->sendFullPlayerListData($player);
    $p->spawnToAll();
}

 

This doesn't change my skin. And I have no errors. (steve.php is in the directory /skins)

PHP:

public function skinChange(Player $player){
    $skin = file_get_contents($this->getServer()->getDataPath()."skins/steve.txt");
     $slim = false;
    $player->setSkin($skin, $slim ? 'Standard_CustomSlim' : 'Standard_Custom');
    $player->despawnFromAll();
        $this->getServer()->removePlayerListData($player->getUniqueId());
        $this->getServer()->sendFullPlayerListData($player);
    $player->spawnToAll();
}
public function onJoinn(PlayerJoinEvent $e){
    $o = $e->getPlayer();

$this->skinChange($o);
}


 

Create a folder?

PHP:

@mkdir($this->getServer()->getDataPath()."skins");

 

I already said, that I saved it in the folder...

 

I really have a problem changing the skin
