有条件的停止计时器只能第一次使用？ [英] Stop timer with conditional only works first time?
问题描述
我正在写一个谁想成为一个百万人的游戏，我已经设置了一切，这只是计时器的一个问题。
I'm writing a "Who Wants to Be a Millionare" game and I have everything set up, it's just a problem with the timer.
游戏有效像这样：如果用户得到正确的问题他/她继续前进。如果没有，游戏结束，他们可以选择再次玩。
The game works like this: if the user gets the question right he/she moves on. If not, the game is over and they can opt to play again.
当游戏第一次运行时，它很好并且计时器完成应有的操作 - 从30秒开始并倒计时，显示秒数。
When the game first runs it's fine and the timer does what it should -- start at 30 seconds and count down, displaying the seconds.
然而，当用户点击再次播放按钮时，前一个计时器继续使用新计时器。像这样：
However, when the user clicks the "play again" button, the previous timer continues with the new timer. Like this:
-timerA在用户输掉前20秒（由a表示）。
-timerA had 20 seconds left before the user lost (indicated by a).
- timerB在下次比赛开始时开始（由b表示）。
-timerB begins the next time the game is played (indicated by b).
输出：20a 29b 19a 28b 18a 27b 17a 26b ....... 2a 11b 1a 10b 9b 8b 7b 6b 5b 4b 3b 2b 1b
output: 20a 29b 19a 28b 18a 27b 17a 26b ....... 2a 11b 1a 10b 9b 8b 7b 6b 5b 4b 3b 2b 1b
所以这是我的计时器类CountDown：
So here is my timer class called CountDown:
import java.util.Timer;
import java.util.TimerTask;
public class CountDown {
static Timer timer;
public static int seconds = 30;
public CountDown() {
timer = new Timer();
timer.schedule(new DisplayCountdown(), 0, 1000);
}
class DisplayCountdown extends TimerTask {
int seconds = 30;
public void run() {
if (seconds == 0) {
timer.cancel();
timer.purge();
return;
}
if (seconds > 0) {
PlayFrame.timer.setText("" + seconds); //jLabel used to display seconds
seconds--;
if (seconds < 30) {
if (PlayFrame.right == true) { //check if question was answered correctly
System.out.print("true"); //testing purposes
PlayFrame.right = false;
PlayFrame.showQuestion();
PlayFrame.startTimer();
seconds = 0;
//break;
}
else if (PlayFrame.right == false) {
//break;
}
}
else if (seconds == 0) { //if time runs out its automatic wrong answer
PlayFrame.wrong();
//break;
}
else {
PlayFrame.wrong();
PlayFrame.timer.setText(null);
timer = new Timer();
//break;
}
}
System.out.println(seconds); // for testing purposes only
}
}
}
这是我的一些PlayFrame：
and here is some of my PlayFrame:
import java.awt.Color;
import java.util.Timer;
public class PlayFrame extends javax.swing.JFrame {
public static void wrong() {
//determines which losing frame to show
if (count <= 2){
LossLevel0 L0 = new LossLevel0();
L0.setVisible(true);
}
else if (count > 2 && count <= 6 && count != 6){
LossLevel1 L1 = new LossLevel1();
L1.setVisible(true);
}
else {
LossLevel1 L1 = new LossLevel1();
L1.setVisible(true);
}
//"supposed" to stop the timer
CountDown.timer.cancel();
CountDown.timer.purge();
}
public static void startTimer() {
//creates new CountDown object and timer, also resets seconds
CountDown countdown = new CountDown();
CountDown.timer = new Timer();
CountDown.seconds = 30;
}
我认为当我重新开始游戏时可能会遇到麻烦。唯一的代码是我在游戏开始之前将所有变量重置回原始状态。像这样：
I think the trouble may be in when I restart the game. The only code that is in there is I reset all of my variables back to its original state before the game started. Like so:
// Reset Everything
PlayFrame.count = 0;
PlayFrame.answer = new String();
PlayFrame.count = 0;
PlayFrame.right = false;
PlayFrame.winnings = 0;
CountDown.seconds = 30;
CountDown.timer = new Timer();
CountDown.timer.cancel();
CountDown.timer.purge();
