Command Args

Hey does anyone know how to get the amount of something in code. Example I want to pay someone money /pay karan 321, how would i get the 321 in code? Sorry if you don't understand.

 

Just use args[1] in the onCommand() part of your code to get the second argument (321) of your command.

 

How? I want to keep both especially the player.

 

Do it like this:

PHP:

$playername = $args[0];   // Name of the player entered, in your example 'karan'
$money = (int)$args[1];   // Amount of money to give to 'karan', in your example '321'

// Check if player is online:
if($this->getServer()->getPlayer($playername)) {   // returns NULL if player is offline
    // some code
}

// Check if both arguments are set:
if(isset($args[0]) && isset($args[1])) {
    // some code
} else {
    // error message
}


 

Ok but how would i do this. After you put the amount like "123" it gives you paper when you right click it it gives you money so args[1], how would i get args[1] on PlayerinteractEvent if you know what I mean?

 

Save it into a global array together with the player's name

 

Any code?

 

Do you know how?

 

Create a public property:

PHP:

public $data = [];


Give the sender paper and add the player's name plus the amount the money to $data (in your onCommand() code):

PHP:

$sender->getInventory()->addItem(Item::PAPER);
$this->data[$sender->getName()] = (int)$args[1]; // adds the command-sender's name as key and $args[1] as value


Use the PlayerItemHeldEvent to check if the player is right-clicking/holding the paper item and get $args[1] (amount of money to give to the player):

PHP:

$player = $event->getPlayer();
if(array_key_exists($player->getName(), $this->data)) { // if player ran the command and got paper
    // give the player money
}


 

Um how would this work

 

Something like this:

PHP:

public $data = [];
// your onEnable() code here

public function onCommand(CommandSender $sender, Command $command, string $label, array $args): bool {
    switch($command->getName()) {
        case "givemoney":
            if(isset($args[0]) && isset($args[1])) {
                $playername = $args[0];
                $money = (int)$args[1];
                if($this->getServer()->getPlayer($playername)) {   // returns NULL if player is offline
                    $sender->getInventory()->addItem(Item::PAPER); // gives the player paper
                    $this->data[$sender->getName()] = (int)$args[1]; // adds the player to the $data array, key = playername, value = amount of money to give
                } else {
                    // error, user is offline
                }
            } else {
                // send usage
            }
            break;
    }
}

public function onItemHeld(PlayerItemHeldEvent $event) {
    $player = $event->getPlayer();
    if(array_key_exists($player->getName(), $this->data)) { // if player ran the command and got paper
        // give the player money
    }
}


 

It would be better to use a private class property for in-class use

If you don't know how to program in PHP, learn before you ask questions on these forums. This is a place for PocketMine-MP API questions, not generic PHP

 

Yes, I wasn't literally meaning a global variable, but referring form of variable that can be accessed in all the needed sections of the plugin.
