所以我有一个名为JustExplode的Minecraft插件，我试图让它如此，如果有人有权限justexplode.timer，他们必须等待10分钟才能再次使用命令/爆炸。它不工作，我尝试了多种方式，而且我对编程新手......有人能帮助我吗？这是我的主类JustExplode.java：如何在Bukkit中设置权限？

        Player player = (Player) sender; 


        player.sendMessage(localMessage2); 

       elapsedTime = (new Date()).getTime() - startTime; 
      } 



     } 
     return true; 

} 
     return true; 

} 
}

，这里是我的config.yml我设置：

# Default config file for JustExplode, by Sam1370 
# There isn't a reload config command for right now, just reload or restart the server 

# Change this to the message you want to see when you are exploding a player 
# Put %player% in it to get the player that you are exploding 
# Color codes are now supported, as opposed to version 1.0.8.2. YES!!! 
message: "&aExploded &c%player%!" 

# Change this to the message you want to see when a player tries to do /explode with the permission justexplode.timer 
# Put %timeleft% in it to get the time left before they can explode again 
# Color codes are supported 

timer: "You can't explode anyone for %timeleft%!" 

# Specify how many minutes, in milliseconds, how long you want someone to wait before they can do /explode again 
# The default is 600000 milliseconds, which is 10 minutes 
timerMinutes: 600000

任何人都知道如何做到这一点？提前致谢。

对于这些类型的延迟，你需要使用System.currentTimeMillis()和简单HashMap

如何？

这实际上很简单，让我给你看几个星期前我写的例子。

private static HashMap<CommandSender, Long> lastExplodeUses = new HashMap<>(); 

public static HashMap<CommandSender, Long> getLastExplodeUses() { 
    return lastExplodeUses; 
} 

public static void setLastExplodeUse(CommandSender player, long till) { 
    lastHelpopSended.put(player, till); 
} 

public static boolean canExplode(CommandSender player) { 
    long timeExploded = lastExplodeUses.get(player) == null ? 0 : lastExplodeUses.get(player); 
    if (timeExploded == 0) return true; // if it's 0 - you can execute explode command. 
    long timeCurrent = System.currentTimeMillis(); // current time in millis 
    if (timeExploded < timeCurrent) { // if the timeExploded is lower than timeCurrent you can execude explode command. 
     return true; 
    } 
    return false; // if not, you cant. 
}

下一步是什么？你需要添加一些功能给你的命令。

if (sender.hasPermission("justexplode.timer")) { // if player has permission, if not - bypass the timer. 
    if (!canExplode(sender)) { 
     // you can't explode yet :/ 
     return; 
    } 
    setLastExplodeUse(sender, System.currentTimeMillis() + 10 * 1000); // set the till time to explode use. Current time + 10000, 10000 = 10 seconds. 
} 
// there you can do your explosion etc.

切记！如果您正在创建例如kits，当延迟大约为24 hours长时，您需要将该HashMap保存到MySQL或其他地方并在开始时加载！

嘿，谢谢！我会试试看！ – Sam1370

嘿，我把“少数功能”代码放在哪里？我试图在你提供的第一个示例代码之后加上它，但它一直说“无法访问的代码”。我在哪里放？ – Sam1370

是'return;'应该是真的还是假的？ – Sam1370

当某人执行命令/爆炸时，会将玩家姓名和当前时间戳存储在地图中。当用户再次尝试执行该命令时，检查播放器是否在地图中，并且时间差等于ro大于config.yml中设置的时间。

小例子代码：

Map<Player, Long> times = new HashMap<>(); 

@Override 
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) { 
    if (!(sender instanceof Player)) 
    return false; 

    Player player = (Player) sender; 

    if (times.contains(player) && times.get(player) >= delay) { 
    //execute command 
    times.put(player, System.currentTimeMillis()); 
    } else if (!times.contains(player)) { 
    //execute command 
    times.put(player, System.currentTimeMillis()); 
    } 
}

嗯......怎么样？我是新手编程和Java，所以我不知道该怎么做......对不起，打扰你 – Sam1370
