WorldServer.php 文件 1306行， updatePopulation函數(shù)：

public function updatePopulation($totalPlayers) 
{
    $this->pushBroadcast(new Messages\Population($this->playerCount, $totalPlayers ? $totalPlayers : $this->playerCount));
}

額，沒看出來哪里錯了。
應(yīng)該怎么拼呢？

下面是 Population 類：

namespace Server\Messages;

class Population
{
    public $world = 0;
    public $total = 0;
    public function __construct($world, $total)
    {
        $this->world = $world;
        $this->total = $total;
    }

    public function serialize()
    {
        return array(TYPES_MESSAGES_POPULATION, 
                $this->world,
                $this->total, 
        );
    }
}

然后，new 一個 Messages\Population對象的時候，第一個參數(shù)不應(yīng)該是一個worldServer的實例嗎？好像不應(yīng)該是$this->playerCount?

沒錯

嗯。
