My timer code isnt working

PHP:

public function onRun($currentTick){

        $players = $this->plugin->getServer()->getLevelByName("GDHub")->getPlayers();
Foreach($players as $array){
Echo(count($players));
        if (count($players) >= 1) {
Echo('test 1');
            $this->tts--;
            $this->plugin->getServer ()->broadcastPopup($this->plugin->gameprefix . C::GREEN . "Starting in" . $this->tts, $array);
            if ($this->tts == 0) {
Echo('test 2');
                $this->plugin->getServer()->broadcastMessage($this->gameprefix . "Test");
                 }
            }
        }
    }
}

Try this

 

When i change

PHP:

if(count($pl) > 1) {

to

PHP:

if(count($pl) > 0) {

it work and start timer with 0 players in world
but if it is

PHP:

if(count($pl) > 1) {

and i join arena it doesnt start.. It start when join 2nd player or why it dont work???

 

You should use count($pl) >= 1

 

Learn how logic operators work in PHP.

PHP:

// Check if there is at least one player in the world
if(count($pl) >= 1) {
  // do stuff
}


You should already know PHP before you start writing PocketMine plugins, or you'll be stuck here with stupid issues like this until you finally decide to learn PHP.

 

Why it doesnt work with count($pl) >= 5 ?? It is god or no??

PHP:

<?php

namespace GetDown;

use pocketmine\Player;
use pocketmine\Server;
use pocketmine\scheduler\PluginTask;
use pocketmine\utils\Config;
use pocketmine\utils\TextFormat;
use pocketmine\utils\TextFormat as C;
use GetDown\Main;
use pocketmine\math\Vector3;
use pocketmine\plugin\Plugin;

class Timer extends PluginTask
{
    private $plugin;
    public $tts;

    public function __construct(Main $plugin)
    {
        $this->plugin = $plugin;
        $this->tts = 30;
        parent::__construct($plugin);
    }

    /**
     * @param $currentTick
     */
    public function onRun($currentTick)
    {
        foreach ($this->plugin->getServer()->getLevelByName("GDHub")->getPlayers() as $pl) {
            if (count($pl)>=5) {
                $this->tts--;
                //$pl->setExpLevel($pl->getExpLevel() - 1);
                $pl->sendPopup($this->tts);
                if ($this->tts == 0) {
                    $this->plugin->getServer()->getScheduler()->cancelTask($this->getTaskId());
                    $pl->sendMessage($this->plugin->gameprefix . C::GREEN . "Game started!");
                    $this->plugin->changePhase(2);
                    $pl->teleport(new Vector3(1, 1, 1, "gd1"));
                    $this->plugin->getServer()->getScheduler()->cancelTask($this->getTaskId());
                }
            }
        }
    }
}

 

You're counting a non-array. You can't count a foreached array.

 

count can be used only when the array

PHP:

<?php

namespace GetDown;

use pocketmine\Player;
use pocketmine\Server;
use pocketmine\scheduler\PluginTask;
use pocketmine\utils\Config;
use pocketmine\utils\TextFormat;
use pocketmine\utils\TextFormat as C;
use GetDown\Main;
use pocketmine\math\Vector3;
use pocketmine\plugin\Plugin;

class Timer extends PluginTask
{
    private $plugin;
    public $tts;

    public function __construct(Main $plugin)
    {
        $this->plugin = $plugin;
        $this->tts = 30;
        parent::__construct($plugin);
    }

    /**
     * @param $currentTick
     */
    public function onRun($currentTick)
    {
        $p = $this->plugin->getServer()->getLevelByName("GDHub")->getPlayers();
        if(count($p)>=5) {
            foreach($p as $pl) {
                $this->tts--;
                //$pl->setExpLevel($pl->getExpLevel() - 1);
                $pl->sendPopup($this->tts);
                if ($this->tts == 0) {
                    $this->plugin->getServer()->getScheduler()->cancelTask($this->getTaskId());
                    $pl->sendMessage($this->plugin->gameprefix . C::GREEN . "Game started!");
                    $this->plugin->changePhase(2);
                    $pl->teleport(new Vector3(1, 1, 1, "gd1"));
                    $this->plugin->getServer()->getScheduler()->cancelTask($this->getTaskId());
                }
            }
        }
    }
