SlapperTrait newbie coding

hoe i solve this problem?

[06:48:37] [Server thread/CRITICAL]: ParseError: "syntax error, unexpected '=', expecting ')'" (EXCEPTION) in "plugins/Slapper-Prince.phar/src/slapper/SlapperTrait" at line 90

and this is my code of line 89,90

public function updateVars() {
$vars = [
"{players}" => $online = count($this->getServer()->getOnlinePlayers(),
"{maxplayers}" = $this->getServer()->getMaxPlayers());
];
}

please help me thanks!

 

There's an unnecessary variable in the array: $online =

Change your array to:

PHP:

$vars = [
    "{players}" => count($this->getServer()->getOnlinePlayers()),
    "{maxplayers}" => $this->getServer()->getMaxPlayers()
];

"{players}" points to getOnlinePlayers()
{maxplayers} points to getMaxPlayers()

If you wanted to keep your $online var, just define it beforehand, then point your placeholder to it:

PHP:

$online = count($this->getServer()->getOnlinePlayers());
$vars = [
    "{players}" => $online,
    "{maxplayers}" => $this->getServer()->getMaxPlayers()
];

 

The first code doesn't seem right. There is it fixed.

PHP:

$vars = [
    "{players}" => count($this->getServer()->getOnlinePlayers()),
    "{maxplayers}" => $this->getServer()->getMaxPlayers()
];

 

i already have this but thanks i need player count in other world can you help me?

 

count(Level->getPlayers());

 

where i input this code?

 

First, please format your code and put it in a code block next time.

You already have the necessary code to grab the world's player count here:

PHP:

"{world_player_count}" => count($player->getLevel()->getPlayers())


 

how can i upload my code into block? im new here sorry

 

You can add a code block by clicking the plus sign:

And then add your code after you select PHP as the language:

 

PHP:

<?php

declare(strict_types=1);

use pocketmine\Player;

            $this->namedtag->setFloat("Scale", 1.0, true);
        }
        $this->getDataPropertyManager()->setFloat(Entity::DATA_SCALE, $this->namedtag->getFloat("Scale"));
    }

            $playerData = $data ?? $this->getDataPropertyManager()->getAll();
            unset($playerData[self::DATA_NAMETAG]);
            $pk = new SetEntityDataPacket();
            $pk->entityRuntimeId = $this->getId();
            $pk->metadata = $playerData;
            $p->dataPacket($pk);

            $this->sendNameTag($p);
        }
    }

        $this->namedtag->setInt("NameVisibility", $visibility, true);
        $this->namedtag->setFloat("Scale", $scale, true);
    }

    public function getDisplayName(Player $player): string {
        $vars = [

ok thanks

how can i add the player after joining in another world like prison,pvp,etc? to see player playing in this world?

 

Not sure what you're asking, can you word it differently?

 

i mean when other player click the slapper automatic teleport into prison world then the slapper prison show player how many people in prison

like

PRISON
JOIN: 0

 

You can take a look at my NaviCompass plugin here:
https://github.com/Xenophilicy/NaviCompass/blob/master/src/Xenophilicy/NaviCompass/NaviCompass.php
I have that exact function in there.

If you know the name of the level, you can use something like this:

PHP:

$this->getServer()->getLevelByName($levelName)


Then use that level object to get the player count accordingly

 

i cant find youre code in my code
and i search this
$this->getServer()->getLevelByName($levelName)
no one can see this

 

That code isn't in my plugin, that was simply an example of what you could do in order to complete your goal. The part you need is around lines 254-284.

 

PHP:

else{
                $subtext = $this->config->getNested("UI.World-Button-Subtext");
                $worldPlayerCount = 0;
                foreach($this->getServer()->getLevelByName($value[2])->getPlayers() as $p){
                    $worldPlayerCount += 1;
                }
                $subtext = str_replace("{current-players}", $worldPlayerCount, $subtext);
                if(isset($value[3])){
                    $search = $value[3];
                    $file = $value[4];
                }

this is i found in youre code where i input this my code?

 

Well I'm not going to spoon feed you, that's just how I managed to do it in my plugin. I'm leaving it to you to implement it in your plugin

 

but i dont know where i input the code in my code

 

Lol are you saying you don't understand your own code?

 

this is not my code this slapper from poggit i dont know where line put your code
