How to get a plugin to Read whats on a sign Detect when its tapped and Write whats on the sign

I would like to know how to have my plugin Read whats on a sign when a player places it, How to detect when its tapped, and write what is on the sign. Thanks in advance!

PHP:

    public function playerBlockTouch(PlayerInteractEvent $event)
            $sign = $event->getPlayer()->getLevel()->getTile($event->getBlock());
            if(!($sign instanceof Sign)){
                return;
            }
            $sign = $sign->getText();
            $sign[0] //Line1
            $sign[1] //Line2
            $sign[2] //Line3
            $sign[3] //Line4

    }


There is such thing called PocketMine API Documentation.

PHP:

public function onSignChange(SignChangeEvent $event){
$line_1 = $event->getLine(0);
// ... and so on

// Write something on sign
// $sign is instanceof Sign
// Or you may use $event in this function context
$sign->setLine(0, "Text");
$event->setLine(0, "Text");
}


Thx guys!

I am guessing i need to import (use) pocketmine\block\Sign right?

He asked for tap event

why are you telling him code to write to the sign he wants to get the text on the sign what @Tim // robske Büba said was correct

No, you don't need it.
Also, it's not a block, it's a tile.

This is off-topic, but as a matter of fact, you can make your event handler function names, as long as not conflicting and not going to conflict, as simple as possible, because nobody would really read them. It may be good to make them represent what event they handle (and usually start with `on` so that callers can notice that they are event handlers and instantly skip them as they are not (generally) useful), but the parameter already explains everything, so you don't really need to make it so descriptive like playerBlockTouch, but is OK to be as simple as onBT

Grammar.

No.
pocketmine\tile\Sign;
