所以我有一个名为JustExplode的Minecraft插件，我试图让它如果有人拥有justexplode.timer的权限，他们必须等待10分钟才能再次使用命令/ explode。它不起作用，我尝试了多种方式，而且我是编程的新手......有人可以帮助我吗？这是我的主要类JustExplode.java：

这是我设置的config.yml：
# 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？提前谢谢。

当有人执行命令/爆炸时，将地图中的玩家姓名和当前时间戳存储起来。当用户再次尝试执行该命令时，检查播放器是否在地图中，以及时间差是否等于大于config.yml中设置的时间。
小示例代码：
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());
}
}

对于这些类型的延迟，您需要使用System.currentTimeMillis()和简单的HashMap
这实际上非常简单，让我向您展示几周前我写的一个例子。
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？您需要在命令中添加一些函数。
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.
请记住！ 如果您在延迟大约kits长时创建24 hours，则需要保存HashMap 1}}到MySQL或其他地方并加载启动！
