Question

所以我最近尝试为我的世界制作一个bukkit插件。我的想法是，这只是一个测试插件，看看我是否可以做到，显然我不能。这是我提出的代码

package me.glowhoo.BlockChanger;  import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
public class BlockChanger extends JavaPlugin
{
@Override public void onEnable() {
    Bukkit.getLogger().info(this.getDescription().getName() +
            " has been enabled");
     }
@Override public void onDisable() {
    Bukkit.getLogger().info(this.getDescription().getName() + " has been disabled");
    } 
@Override public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
    /*command: /tpa Glowhoo
     * args.length = 1
     * args[0] = Glowhoo
     * command.getName() = tpa
     */
    if (cmd.getName().equalsIgnoreCase("message")){
        if(sender instanceof Player)
        {
            /*ComandSender sender-who sent the command
             * Command cmd- the command that was executed
             * String commandLabel-the command alias that was used
             * String[] args-array of additional arguments
             */
            sender.sendMessage(ChatColor.RED +"Hello player!");
        }else
        {
            sender.sendMessage(ChatColor.AQUA +"Hello console!");               
        }
     }
    return false;
   }
 }

所以问题就在于，无论何时我加载服务器，它都说＆＃34; BlockChanger已经启用＆＃34;，但是当我尝试键入它所拥有的唯一命令（消息）或/消息，什么都没发生，它说这是一个无法识别的命令，并输入/帮助信息。但问题并没有结束，每当我真正试图让插件运行时，90％的时间我都有一个plugin.yml错误，我不完全理解，但如果有人知道的话关于这个问题的任何事情，请回复

我的plugin.yml文件在这里（注意：这个plugin.yml副本实际上有效，但命令本身并没有。）：

name: BlockChanger
version: 1.0
main: me.glowhoo.BlockChanger.BlockChanger
description: 
commands: 
message:
description: -no desc-
usage: /message

Answer 1

您的plugin.yml不正确。您需要在message下缩进commands以定义节点。目前commands是一个关键值。将相关部分更改为：

commands: 
  message:
    usage: /message

Answer 2

现在是将来的某个时间，但是如果你再次使用它，当你有一个命令时，你需要返回true，否则它会告诉你它是一个不正确的命令，即使你的.yml /。 yaml文件设置正确。因此，在调用时，您需要做的是使其注册命令：

package me.glowhoo.BlockChanger;  import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
public class BlockChanger extends JavaPlugin
{
@Override public void onEnable() {
    Bukkit.getLogger().info(this.getDescription().getName() +
            " has been enabled");
     }
@Override public void onDisable() {
    Bukkit.getLogger().info(this.getDescription().getName() + " has been disabled");
    } 
@Override public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
    /*command: /tpa Glowhoo
     * args.length = 1
     * args[0] = Glowhoo
     * command.getName() = tpa
     */
    if (cmd.getName().equalsIgnoreCase("message")){
        if(sender instanceof Player)
        {
            /*ComandSender sender-who sent the command
             * Command cmd- the command that was executed
             * String commandLabel-the command alias that was used
             * String[] args-array of additional arguments
             */
            sender.sendMessage(ChatColor.RED +"Hello player!");
        }else
        {
            sender.sendMessage(ChatColor.AQUA +"Hello console!");               
        }
        return true;
     }
    return false;
   }
 }

Answer 3

U need to register this class as command executor in onEnable method.

Bukkit插件无法正常工作？
