我正在用Java制作rummikub游戏，我想实现一个运行2分钟的计时器。在2分钟内，用户必须输入有关他们是否要播放，跳过还是要转弯（如果已经播放了图块）的输入。如果他们选择游戏，则需要选择是要播放单个图块，进行融合还是退出序列（所有这些输入都必须在2分钟内完成）。如果他们在2分钟内仍未完成转牌，则该转牌必须结束且不需输入任何信息，下一位玩家将进行转牌。我将在下面发布一些代码。我应该如何实施此计时器？我在Human类和GameTimer类中有2种播放方法，在Game类中有playTurn（）方法。此刻我正在测试10秒

答案 0 :(得分：0)
这是非常快速的编写代码，但我希望它可以使您对事件管理有更好的看法。
private GameTimer _task; // the object.
// .....................
// Put these 2 lines wherever you call the event to start.
_task.setStartTime(System.currentTimeMillis() + (60000L * eventTime)); // eventTime == 2 minutes
ThreadPoolManager.getInstance().executeGeneral(_task);
// .....................
class GameTimer implements Runnable
{
private long _startTime;
public ScheduledFuture<?> nextRun;
public GameTimer(long startTime)
{
_startTime = startTime;
}
public void setStartTime(long startTime)
{
_startTime = startTime;
}
@Override
public void run()
{
int delay = (int) Math.round((_startTime - System.currentTimeMillis()) / 1000.0);
if (delay == 0)
{
// start
if (isStarted())
{
stop();
// You can place a scheduler here to trigger an auto-start.
}
else
{
start();
nextRun = ThreadPoolManager.getInstance().scheduleGeneral(this, endEvent);
// endEvent is the time you want the run() method to run again.
// In this case, when the event is finished.
// This line is triggering the jvm to auto run this method again in the given time.
// So if the event is already started, the run() method will run again and it will close it again.
}
}
}
}
仅提及代码只是如何更好地重写事件计时器的示例。
希望有帮助！
