Solved Whats wrong?

PHP:

[15:34:14] critical> "Could not pass event 'pocketmine\event\player\PlayerInteractEvent' to 'Jump v1.0.0': Call to a member function getText() on null on JackboyPlay\Jump\Main
[15:34:14]critical> Error: "Call to a member function getText() on null" (EXCEPTION) in "/Jump/src/JackboyPlay/Jump/Main" at line 93

Whats the error?

Here the function:

PHP:

public function onSchildKlick(PlayerInteractEvent $event){
$player = $event->getPlayer();
$block = $event->getBlock();
$tile = $event->getPlayer()->getLevel()->getTile($block);
  $text = $tile->getText();
if($tile instanceof Sign){
if($text[0] == "§c[§aJump§c]" && $text[2] == "§eLobby" && $text[3] == "§fJump1"){
$this->jump1[$player->getName()] = true;
$player->sendMessage("§7[§eJump§7] §aDu hast das Spiel §cJump1§a betreten!");
}
}
}

PHP:

if($tile instanceof Sign){

Use this sorry for my mistake

PHP:

        if($event->getBlock()->getId() == 68 || $event->getBlock()->getId() == 63) {
            $sign = $event->getPlayer()->getLevel()->getTile($event->getBlock());
            if($sign instanceof Sign) {
                $text = $sign->getText();
                               if($text[0] == "[Test]"){

I have it already!

Thanks!

Always remember that PHP code in a function is run from left to right, from up to down. The code above is executed before the code below. Code before an if-block is executed whether the if-block behind it is executed or not. You executed $tile->getText() without checking $tile !== null, so there is a chance that you are executing $tile->getText() when $tile is null.

You have an deeply ironic-notfunny-good-useful way of explaining things this makes my brain explode about whether i should HATE you or fucking LOVE you

Hmm? Ironic?

Be quiet
@PEMapModder I know its useful for killstreaks without arrays
