Solved Set sign text

Where is the function to set sign text? I thought it was in \pocketmine\tile\sign?
And also an example on how to use would be nice

EDIT:nvm i found it not exactly sure how to use it though

I will be nice
search before creating threads! i already posted about this -_-
But Ok :

PHP:

$tile = $this->getServer()->getLevelByName("world")->getTile(new Vector3($x,$y, $z));//gets the position
if($sg1tile instanceof Sign){//prevent from crash if the current position isn't a sign
$tile->setText("Text Line 1", "Text Line 2", "Text Line 3", "Text Line 4");
}

This is what im using

PHP:

 public function lottoGame(PlayerInteractEvent $event){
  $block = $event->getPlayer()->getLevel()->getTile($event->getBlock());
  if($block instanceof Sign){
   $signtext = $block->getText();
   if($signtext[0] === "[Lottery]"){
    $block->setText(
     "§6[Lottery]",
     "§bTap to play"
    );
   }


Oh so you want text replacing when the first line is [Lottery] ?

Its just for good measure lol the goal is when someone creates a sign and the first line is
[Lottery] the text will be replaced with a colored [Lottery] txt and will become an actual game sign in which when clicked will run a command(the lottery command)

Sorry, Can't post because i am not sure of something

Not sure whatcha mean but ok

More effecient

PHP:

public function onSignCreate(SignChangeEvent $event){
if($event->getLine(0) === 'lottery'){ // check does player is creating lottery sign
    if($player->hasPermission('some.perm')){//  check perm.
            // Format sign
              $event->setLine(0, '[LotterY]');
              $event->setLine(1, 'Tap to play');
              $event->setLine(2, '');
              $event->setLine(3, '');
           // Save sign
             $this->signs[$event->getBlock()->getPosition()] // Blah blah, or whatever you do it.
          // Inform player about the action he did
            $event->getPlayer()->sendMessage('[LotterY] Sign created');
    }
}
}


when clicked will run a command(the lottery command)

I bet you got warning for doing that lol because when I put my words in Bold. I got a warning point

What was the point of this?
