我正在编写一个“谁想成为百万富翁”游戏,我已经设置好了一切,只是计时器有问题。
游戏的运作方式是这样的:如果用户答对了问题,他/她就继续前进。如果没有,游戏就结束了,他们可以选择重新玩。
当游戏第一次运行时,一切正常,计时器会执行其应有的操作 - 从 30 秒开始倒计时,显示秒数。
然而,当用户单击“再次播放”按钮时,先前的计时器将继续使用新的计时器。像这样:
-timerA 距离用户失败还剩 20 秒(用 a 表示)。
-timerB 在下次玩游戏时开始(用 b 表示)。
输出:20a 29b 19a 28b 18a 27b 17a 26b ...... 2a 11b 1a 10b 9b 8b 7b 6b 5b 4b 3b 2b 1b
这是我的计时器类,名为 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:
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;
}
我认为当我重新启动游戏时可能会出现问题。那里唯一的代码是我在游戏开始之前将所有变量重置回其原始状态。就像这样:
// 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();
