bukkit命令識別n

我正在爲服務器製作一個具有基本命令的插件，並且我已經放入了一些正常工作的事件。但是當我嘗試添加命令時，它不起作用。（在你問之前，我用一個簡單的sendMessage替換了onCommand部分的所有內容，並且它什麼都不做）。當我執行命令時，它只是告訴我我已經在plugin.yml中使用的用法。bukkit命令識別n

這裏是我的代碼：對不起，這是很長的

} 

}

這裏是我plugin.yml：

name: PepsiCore 
author: P3pi 
version: 1.0.3 
main: com.pepsi.core.Main 

commands: 
    pcore: 
     description: Core command 
     usage: /pcore 
    pepsicore: 
     description: Core command 
     usage: /pepsicore

感謝您的幫助

Bukkit處理命令的方式是運行JavaPlugin類的onCommand方法。具體的onCommand方法，它的參數CommandSender sender, Command command, String label, String[] args

你的方法有錯誤的順序的參數，如Vlexing提到的，所以它沒有運行的方法時運行命令，這樣反而從JavaPlugin只包含運行onCommand方法return false;。 Bukkit仍然可以識別你的命令，因爲你的plugin.yml，但是當它試圖運行你的方法時，它得到了false，所以它打印出你的使用信息。

基本上，只是修復你的論點的順序，並遵循Vlexing的答案，你應該設置。

當onCommand()方法編寫代碼，代碼塊應始終爲return true，例如：

if (args[0].equalsIgnoreCase("ranks")) { 
     sender.sendMessage(Util.transMsg("&e<!> &6&lPepsiCore &8>> &eRanks: &6guest&e, &6gold&e, &6diamond&e, &6emerald&e, &6yt&e, &6staff&e, &6developer&e, &6owner")); 
     return false; 
    }

您使用return false;這會給你plugin.yml的用法。請參閱this spigot thread talking about the same issue。

我已經完成了你所說的，它仍然具有完全相同的問題... onCommand部分中的所有返回錯誤現在都返回true並且仍然不起作用，並且還試圖在底部返回true假，其餘返回true ....請幫忙嗎？ – graphicalcake95

我也注意到，對於你的onCommand（）參數，你有'Command cmd，CommandSender sender，String cmdLbl，String [] args'。使用參數的正確方法是'public boolean onCommand（CommandSender sender，Command cmd，String commandLabel，String [] args）{}'。實際上並不知道這是否有助於解決您的主要問題，但我想指出。 – Vlexing

讓他們都返回true，它應該隱藏消息 – Squiddie
