setText() on null, setBlockIdAt() glitching and newExplosion not working

First of all I wish to say it is my first pocketmine plugin i ever developed, second i've been spent almost 8 hours in finding a solution, 3+ days, im also a student and i dont have lot of time.

I cannot find that three problems, i may have included some classes that arent even used, i've been a lot learning pocketmine api and im so much better than before.

Im hispanic also. So i have my plugin RaidCommand and i am having the three issues... running pocketmine for version v1.0.8, would love if you guys can also test it yourself the errors!

Main file, RaidCommand.php, and the only one

PHP:

<?php

namespace RaidCommand;

use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\CommandExecutor;
use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\event\player\PlayerInteractEvent;
use pocketmine\math\Vector3;
use pocketmine\level\Level;
use pocketmine\tile\Sign;
use pocketmine\level\Explosion;
use pocketmine\block\Block;
use pocketmine\level\Position;
use pocketmine\Server;
use onebone\economyapi\EconomyAPI;

class RaidCommand extends PluginBase implements Listener
{

public function onEnable()
{
$this->getServer()->getPluginManager()->registerEvents($this, $this);
$this->getLogger()->info("§aEnabling " . $this->getDescription()->getFullName() . "...");

}

public function onDisable()
{
$this->getLogger()->info("§cDisabling " . $this->getDescription()->getFullName() . "...");
}

public function onCommand(CommandSender $sender, Command $command, $label, array $args)
{

if ($command->getName() === "raid") {
if (EconomyAPI::getInstance()->reduceMoney($sender, 35000) == false) {
$sender->sendMessage("§cYou need at least §a35000$ §cto use the raid command.");
return true;
} else {
global $tapRaid;
$name = $sender->getName();
$hand = $sender->getInventory()->getItemInHand();
$sender->sendMessage("§2Touch with a diamond pickaxe the area that you want to do more damage in the land.");
// it should now define $tapRaid to true so that it can end up raiding.. but the variable is lost on the touch public function
$tapRaid = "true";
return true;

}

}
}

public function onTouch(PlayerInteractEvent $event)
{
global $tapRaid;
$player = $event->getPlayer();
$block = $event->getBlock();
$itemTapped = $event->getItem();
$level = $player->getLevel();
if ($itemTapped->getId() == "278:0") {
if ($player->getLevel()->getName() == "homestead") {
if (!empty($tapRaid)) {
if ($tapRaid == "true") {
// what i gotto add here is check the land is on the tapped block, then check its owner and check if the land owner has raidcommand.protection perm or return error message

$x = $block->getX();
$stoneY = $block->getY();
$signY = $stoneY + 1;
$z = $block->getZ();

$explosion = new Explosion(new Position($x, $stoneY, $z, $player->getLevel()), 5);
$explosion->explodeA();

$stoneId = "1";
$signId = "323";
$level->setBlockIdAt($x, $stoneY, $z, $stoneId);
$level->setBlockIdAt($x, $signY, $z, $signId);
$getTile = $level->getTile(new Vector3($x,$signY,$z));
$getTile->setText("§c[RAIDED]", "§b" . "$player was", "§bhere", "");

}
}
}
}
}


}

PS: I forgot say title the glitching part is incomplete, what happens is that the first block sets but it sets a cobblestone stair instead of a stone and the sign isnt setting anywhere

 

So anyone can help?

 

What errors are you getting?

 

The errors is the title of this post.. and the,description of it

 

Can you paste the exact error you're getting?

 

setText():
Error found: sign isn't setted one Y more than the stone


setBlockIdAt() (I tapped two times two blocks using the Diamond Pickaxe) and this is what I got, it was supposed to set stone
Error found:
- Placed one block more
- didnt place stone


newExplosion simply no explosion happens and no error in console check the code in the post description

Oh and I wish the player after using /raid to do all once because i were able to place more than once and if newexplosion were working it would explode two times or the amount of times i tap a block so you can help with that

 

Sorry but that doesnt help me, im new to this and i dont know what i got to do, can you give me the correct code just..

 

Try checking if $getTile is instance of Sign tile

PHP:

$getTile = $level->getTile(new Vector3($x,$signY,$z));
if($getTile instanceof Sign){
$getTile->setText("§c[RAIDED]", "§b" . "$player was", "§bhere", "");
}
