所以我正在创建一个基于文本的游戏,我很难找到一种在文本显示之间暂停的方法。我知道线程睡眠会起作用,但我不想对数百行文本执行此操作。这是我所拥有的,但是有没有更简单的方法可以做到这一点?
public class MyClass {
public static void main(String[] args) {
System.out.println("Hello?");
//pause here
System.out.println("Is this thing on?");
/**Obviously I have a pause here, but I dont want to have to use this every time.*/
try {
Thread.sleep(x);
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("Now, what is your name?");
}
}
为什么不简单地将其包装在另一个类中呢?
class DisplayWrapper {
private final static long DEFAULT_PAUSE_MS = 250;
public static void outputWithPause(String text, long ms) {
System.out.println(text);
try {
Thread.sleep(ms);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void show(String text) {
outputWithPause(text. DEFAULT_PAUSE_MS);
}
}
public class MyClass {
public static void main(String[] args) {
DisplayWrapper.show("Hello?");
DisplayWrapper.show("Is this thing on?");
DisplayWrapper.show("Now, what is your name?");
}
正如m.antkowicz在评论中提到的,您需要创建一个打印方法。我举了一个例子:
void printAndSleep(String string, int sleepTimeMs) {
System.out.println(string);
Thread.sleep(sleepTimeMs);
}
现在,无论何时要打印,只需使用我们上面制作的printAndSleep方法即可。这样:
printAndSleep("Hello?", 1000); // Print and pause for 1 second
printAndSleep("Is this thing on?", 2000); // Print and pause for 2 seconds
查看 TimerTask。
你可以像这样使用它:
public static void main(String[] args) {
Timer timer = new Timer();
writeIn(timer, 3000, "Hello?");
writeIn(timer, 6000, "Is this thing on?");
writeIn(timer, 12000, "Now, what is your name?");
closeTimerIn(timer, 13000); // clean exit
}
private static void writeIn(Timer timer, final int millis, final String text){
TimerTask task = new TimerTask() {
@Override
public void run() {
System.out.println(text);
}
};
timer.schedule(task, millis);
}
private static void closeTimerIn(final Timer timer, final int millis){
TimerTask task = new TimerTask() {
@Override
public void run() {
timer.cancel();
}
};
timer.schedule(task, millis);
}
