        /** @var MultiEconomy $multieconomy */
        private $multieconomy;

        public function onEnable(): void{
            $this->multieconomy = $this->getServer()->getPluginManager()->getPlugin("MultiEconomy");
        }

        /**
         * @param Player $player
         * @return array
         */
       
        public function getProcessedTags(Player $player): array{
            $pname = $player->getName();
            $currency1 = $this->multieconomy->getCurrency("Coins");
            $currency2 = $this->multieconomy->getCurrency("Crystal");
            $balance1 = $currency1->getBalance($pname);
            $balance2 = $currency2->getBalance($pname);
            return [
                "{coin}" => $currency1->formatBalance($balance1),
                "{crystal}" => $currency2->formatBalance($balance2)
            ];
        }
    }
