Bukkit 插件：如何使用命令停止计时器

Question

So basically I have

timer.scheduleAtFixedRate(new TimerTask() {
    public void run() {
    }
}

that runs when the command "play" is sent by a player, and I want to stop and reset the timer when a player sends the command "cancel". How can I do this?

Answer 1

By using Bukkit's scheduler API, it's better.

Firstly, start your server:

BukkitTask task = Bukkit.getScheduler().runTaskTimer(myPlugin, () -> {
   // do something
}, 20, 20);

Then, with the task variable, you can cancel it:

task.cancel();

Finally, the next time, you will be able to just create a new timer that will replace the task variable.

Answer 2

You could create a static Timer object and cancel it in your cancel command class.

/play (PlayCommand)

public static Timer timer = null;


timer.scheduleAtFixedRate(new TimerTask() {
   public void run() {
      //Run your Timer code
   }
}

/cancel (CancelCommand)

PlayCommand.timer.cancel();
