java - Bukkit/龙头。当我输入命令时，它只返回命令

Question

当我在游戏中使用命令/heal 时，它会在游戏聊天中返回/heal。我根本不明白为什么会发生这种情况。这是我的代码(全部在一个类中):

public boolean onCommand(CommandSender sender, Command cmd, String label, Strings [] args) {

    Player player = (Player) sender;

    if (cmd.getName().equalsIgnoreCase("heal")) {
        if (sender.hasPermission("city.heal")) {
            player.setHealth(20);
            player.setFoodLevel(20);
            sender.sendMessage("§fYou have been §bhealed §fand §bsated§f.");
            return true;
        }

        if (!sender.hasPermission("city.heal")) {
            sender.sendMessage("§cNo permission.");
            return true;
        }
    }
    return true;
}

这是我的plugin.yml:

main: me.rarfiles.code.Code
name: Test
author: rarfiles
version: 1.0

commands:
  heal:
    usage: /<command>

Answer 1

确保在 onEnable 方法中注册 CommandExecutor。通过执行 getCommand("heal").setExecutor(CommandExecutor 的实例);

您还需要确保检查发件人是否是玩家if(发送者实例 of Player)
