权限设置
看到这里你可能会问，若是没有权限组我该如何配置玩家的 权限 ？既然 Bukkit API 本身并没有提供用户组的预设,
你必须通过安装一款权限组插件，
像 permissionsBukkit 这样的插件来帮助你配置用户群. API 只是提供接口而不是提供已实现的类.

如何进行命令的设计以实现玩家输入相应的指令完成相应的操作？
①编写yml文件，赋予玩家可用操作命令以及权限，包括打开图鉴及装备称号等相关需要输入命令以实现，例如/open 以打开各种界面，/vftxi 以装备特效及称号，/chengjiu 设置或查询玩家的成就点数；
在resources目录下新建一个名为plugin的文件，并将其后缀改为.yml
我所设置的操作命令及权限如下：

②编写Command类，
如对命令进行输入和玩家权限判断以及对玩家进行操作提示；
我所设计的操作命令包括（主菜单界面操作、图鉴界面操作和成就奖励界面操作）如下：
// 主菜单界面操作package com.mands;import com.connorlinfoot.titleapi.TitleAPI;import com.project.minecraft.vexview.MyGui_tujian;import lk.vexview.api.VexViewAPI;import mand;import mandExecutor;import mandSender;import org.bukkit.entity.Player;public class MyCommandOpen implements CommandExecutor {@Overridepublic boolean onCommand(CommandSender commandSender, Command command, String label, String[] strings) {if (strings.length == 0){commandSender.sendMessage("§5-----------图鉴界面模块-----------");commandSender.sendMessage("§5 /open tujianGUi §d打开图鉴列表");commandSender.sendMessage("§5 /open zhiwuGUi§d打开植物图鉴");commandSender.sendMessage("§5 /open shengwuGui §d打开生物图鉴");commandSender.sendMessage("§5 /open zhuangbeiGui §d打开装备图鉴");commandSender.sendMessage("§5 /open taskGui§d打开悬赏任务");return true;}if(commandSender instanceof Player){Player player = (Player) commandSender;if(!player.hasPermission("MyPlugin.open")){return true;}if(label.equalsIgnoreCase("open")){//open <GuiName>if(strings[0].equalsIgnoreCase("tujianGUi")){//打开图鉴界面VexViewAPI.openGui(player, MyGui_tujian.tujianGui());player.sendMessage("§d打开图鉴界面§e成功");TitleAPI.sendTitle(player,5,4,5,"§1Minecraft图鉴","§2图鉴列表");}else if(strings[0].equalsIgnoreCase("zhiwuGui")){//打开植物图鉴界面VexViewAPI.openGui(player, MyGui_tujian.zhiwuGui());player.sendMessage("§d打开植物图鉴界面§e成功");TitleAPI.sendTitle(player,5,4,5,"§1Minecraft图鉴","§2植物图鉴");}else if(strings[0].equalsIgnoreCase("shengwuGui")){//打开图鉴界面VexViewAPI.openGui(player, MyGui_tujian.shengwuGui());player.sendMessage("§d打开生物图鉴界面§e成功");TitleAPI.sendTitle(player,5,4,5,"§1Minecraft图鉴","§2生物图鉴");}else if(strings[0].equalsIgnoreCase("zhuangbeiGui")){//打开装备图鉴界面VexViewAPI.openGui(player, MyGui_tujian.zhuangbeiGui());player.sendMessage("§d打开装备图鉴界面§e成功");TitleAPI.sendTitle(player,5,4,5,"§1Minecraft图鉴","§2装备图鉴");}else if(strings[0].equalsIgnoreCase("taskGui")){//打开装备图鉴界面VexViewAPI.openGui(player, MyGui_tujian.chengjiuGui());player.sendMessage("§d打开悬赏任务界面§e成功");TitleAPI.sendTitle(player,5,4,5,"§1Minecraft图鉴","§2悬赏任务");}else{player.sendMessage("§d打开图鉴界面§e失败，§f请检查输入的指令是否为open <GuiName>");}}}else{commandSender.sendMessage("§d打开图鉴界面§e失败，§f请检查输入的指令是否为open <GuiName>");}return true;}}

③在插件main方法中对命令进行注册，使命令可用可操作。
