how to get the number of players with a specific game-mode

Hey, Iv'e tried to use:

PHP:

$alivePlayers = count($levelArena->getPlayers()->getGamemode(0));

$alivePlayers is defining the number of players in the arena that are still alive (in game-mode 0) and NOT in game-mode 3 (Spectator)... but it gives me this error:

PHP:

[10:15:40] [Server thread/CRITICAL]: Could not execute task Atomization\SkyWars\GameSender: Call to a member function getGamemode() on array
[10:15:40] [Server thread/CRITICAL]: Error: "Call to a member function getGamemode() on array" (EXCEPTION) in "SKYWARS/src/Atomization/SkyWars/Main" at line 932

Can someone help me Understand the error so i dont need to ask about it again.

Here is another thread that I looked at but didn't find a solution.

I also have written: This will simply teleport the players back to spawn on game end.

PHP:

if($alivePlayers == 1){
           foreach($playersInArena as $pl){

                    $pl->getInventory()->clearAll();
                    $pl->getArmorInventory()->clearAll();
                    $pl->removeAllEffects();
                    $pl->teleport($this->plugin->getServer()->getDefaultLevel()->getSafeSpawn());
                    $pl->setHealth(20);
                    $pl->setFood(20);
                    $pl->setNameTag($pl->getName());

                    if(!empty($this->plugin->api)){
                       $this->plugin->api->addMoney($pl,$money);
                    }
          }
}


 

$levelArena->getPlayers() will probably return an array of player objects so you need to loop through each player, retrieve the gamemode and count if gamemode is 0.

 

so something like?

PHP:

$alivePlayers = $levelArena->getPlayers()->count(getGamemode(0));

 

nope, didnt work... get same error:

PHP:

[10:15:40] [Server thread/CRITICAL]: Could not execute task Atomization\SkyWars\GameSender: Call to a member function getGamemode() on array
[10:15:40] [Server thread/CRITICAL]: Error: "Call to a member function getGamemode() on array" (EXCEPTION) in "SKYWARS/src/Atomization/SkyWars/Main" at line 932

and to clarify some things up... $levelArena is defined in the code as:

PHP:

$levelArena = $this->plugin->getServer()->getLevelByName($arena);


 

use a foreach loop as getPlayers() returns an array

 

Nope, something like learn basic programming:

PHP:

$count = 0;
foreach ($levelArena->getPlayers() as $player) {
    if ($player->getGamemode() === 0) {
        $count++;
    }
}

^ That is assuming that "$levelArena->getPlayers()" returns an array of "Player" objects.

 

Lol, considering all those combinations in OP's posts, I think I gave a useful advice.

 

Look at https://github.com/pmmp/PocketMine-MP/blob/master/src/pocketmine/command/defaults/ListCommand.php

 

Thank you all you your help! i was able to find a solution to my problem with @Tee7even advice.. also, i had and did try other variants of my code before you posted here. so i was still working on a fix so thanks again!

 

Here's a single liner:

PHP:

$playersAlive = count(array_filter($levelArena->getPlayers(), function($p){return $p->getGamemode() === 0;}));

 

fixed

 

Thanks for the one liner xd
But what I currently have is easier to understand. Lol

 

Ha..!

PHP:

$count = 0; foreach ($levelArena->getPlayers() as $player) { if ($player->getGamemode() === 0) { $count++; } }

What I mean is that it's not exactly a single liner.

PHP:

$playersAlive = count(array_filter($levelArena->getPlayers(), function($p) {
    return $p->getGamemode() === 0;
}));

 

Without OOP, Its a single liner.. so it can get confusing if code is not written on OOP
