Bukkit 1.12 PlotSquared API 管理菜单：地皮合并功能及金币扣除

以下是用 Java 编写的 Bukkit 1.12 插件，使用 PlotSquared API 来管理菜单功能，并包含地皮合并功能，并根据实际情况扣除金币。\n\njava\nimport org.bukkit.Bukkit;\nimport org.bukkit.ChatColor;\nimport org.bukkit.Material;\nimport org.bukkit.command.Command;\nimport org.bukkit.command.CommandSender;\nimport org.bukkit.entity.Player;\nimport org.bukkit.inventory.Inventory;\nimport org.bukkit.inventory.ItemStack;\nimport org.bukkit.plugin.java.JavaPlugin;\n\nimport com.plotsquared.bukkit.util.BukkitUtil;\nimport com.plotsquared.core.plot.Plot;\nimport com.plotsquared.core.plot.PlotId;\nimport com.plotsquared.core.plot.flag.GlobalFlag;\nimport com.plotsquared.core.plot.flag.PlotFlag;\nimport com.plotsquared.core.plot.flag.registry.FlagRegistry;\nimport com.plotsquared.core.util.Permission;\nimport com.plotsquared.core.util.math.MathUtil;\n\npublic class PlotManagementPlugin extends JavaPlugin {\n private static final String MENU_TITLE = "Plot Management Menu";\n private static final int MENU_SIZE = 9;\n\n private FlagRegistry flagRegistry;\n\n @Override\n public void onEnable() {\n flagRegistry = BukkitUtil.getFlagRegistry();\n registerMergeFlag();\n getLogger().info("Plot Management Plugin enabled.");\n }\n\n @Override\n public void onDisable() {\n getLogger().info("Plot Management Plugin disabled.");\n }\n\n @Override\n public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {\n if (!(sender instanceof Player)) {\n sender.sendMessage(ChatColor.RED + "Only players can use this command.");\n return true;\n }\n\n Player player = (Player) sender;\n\n if (command.getName().equalsIgnoreCase("plotmanage")) {\n if (!player.hasPermission("plotmanagement.menu")) {\n player.sendMessage(ChatColor.RED + "You do not have permission to use this command.");\n return true;\n }\n\n openManagementMenu(player);\n return true;\n }\n\n return false;\n }\n\n private void openManagementMenu(Player player) {\n Inventory menu = Bukkit.createInventory(null, MENU_SIZE, MENU_TITLE);\n\n ItemStack mergeButton = new ItemStack(Material.IRON_BLOCK);\n ItemStack closeButton = new ItemStack(Material.BARRIER);\n\n // 设置合并按钮的名称和Lore\n mergeButton.getItemMeta().setDisplayName(ChatColor.GREEN + "Merge Plots");\n mergeButton.getItemMeta().setLore(\n ChatColor.GRAY + "Merge your current plot",\n ChatColor.GRAY + "with an adjacent plot.");\n\n // 设置关闭按钮的名称\n closeButton.getItemMeta().setDisplayName(ChatColor.RED + "Close");\n\n // 将按钮添加到菜单中\n menu.setItem(3, mergeButton);\n menu.setItem(8, closeButton);\n\n player.openInventory(menu);\n }\n\n private void registerMergeFlag() {\n GlobalFlag mergeFlag = flagRegistry.registerGlobalFlag("merge", Permission.BUILD, "Allow plot merging.");\n\n mergeFlag.getHandler().register(PlotFlag.CLICK, (plot, player, location, info) -> {\n PlotId mergeTargetId = plot.getIntersectedPlots().stream()\n .filter(p -> p.isAdded(plot))\n .findFirst()\n .map(Plot::getId)\n .orElse(null);\n\n if (mergeTargetId == null) {\n player.sendMessage(ChatColor.RED + "There is no adjacent plot to merge with.");\n return false;\n }\n\n Plot mergeTarget = plot.getArea().getPlot(mergeTargetId);\n\n if (plot.getArea() != mergeTarget.getArea()) {\n player.sendMessage(ChatColor.RED + "The adjacent plot is not in the same area.");\n return false;\n }\n\n // 确保两个地皮的所有者相同\n if (!plot.getOwners().equals(mergeTarget.getOwners())) {\n player.sendMessage(ChatColor.RED + "The adjacent plot does not have the same owner.");\n return false;\n }\n\n // 检查玩家是否有足够的金币来合并地皮\n int mergeCost = 100; // 合并地皮的金币费用\n int playerCoins = 0; // 玩家的金币数量，根据实际情况获取\n\n if (playerCoins < mergeCost) {\n player.sendMessage(ChatColor.RED + "You do not have enough coins to merge the plots.");\n return false;\n }\n\n // 扣除金币\n // deductCoins(player, mergeCost); // 根据实际情况扣除金币\n\n // 合并地皮\n plot.merge(mergeTarget);\n player.sendMessage(ChatColor.GREEN + "Plots merged successfully.");\n return true;\n });\n }\n}\n\n\n请注意，上述代码假设您已经正确设置了PlotSquared插件，并且已经将其添加到您的项目依赖中。在代码中有一些需要根据实际情况进行替换的部分，如获取玩家金币数量和扣除金币的逻辑。您需要根据您自己的经济插件或其他方式来实现这些功能。\n\n此外，您还需要根据您自己的需求更改菜单中按钮的图标和功能。上述代码仅提供了一个示例，您可以根据自己的需求进行修改。
