Bukkit 插件不工作?

Bukkit plugin not working?

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,看看我是否能做到,显然我做不到。这是我想出的代码

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;
   }
 } 

所以这个问题是,每当我加载服务器时,它都会显示 "BlockChanger has been enabled",但是当我尝试键入它具有的唯一命令(消息)或 /message 时,没有任何反应它说这是一个无法识别的命令,输入 /help 获取信息。问题并没有就此结束,每当我实际尝试让插件运行时,90% 的时间我都会遇到 plugin.yml 错误,我不完全理解,但是如果你们中的任何人知道任何关于这个问题,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,但命令本身无效。):

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

您的plugin.yml不正确。您需要在commands 下缩进message 来定义一个节点。目前 commands 是一个没有意义的键值。将相关部分改为:

commands: 
  message:
    usage: /message

这是未来的某个时间,但是如果你再次使用它,当你有一个命令时,你需要return true,否则它会告诉你这是一个错误的命令,甚至如果您的 .yml/.yaml 文件设置正确。因此,您需要执行以下操作才能在调用时注册您的命令:

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;
   }
 }

您需要在 onEnable 方法中将此 class 注册为命令执行器。
