java - 使用多个Java概念的Arrow Sorrow Game

这是我的简单箭头排序应用程序代码。

它会生成一个大小为4的随机序列，该序列由上，下，左和/或右箭头键组成，并一次显示一个。如果用户正确重复了该序列，它将显示另一个5键序列。只要用户输入正确的序列，序列的大小就会不断增加，但是如果输入了无效的序列，则序列的大小会减小。

我遇到的问题是，第一次执行是完美无缺的，它甚至第二次显示了序列，但是在第二次迭代期间不接受我的键盘输入。

为了更好地理解该问题，我将其分解为主要的动作执行块和最后的完整代码。

序列产生

for(int flag=1;flag<size;flag++)
    {
    random = randomGenerator.nextInt(4);
    generated[flag]=random;
    setVisible(true);
    switch(random)
        {
            case 0:
            left();
            break;
            case 1:
            up();
            break;
            case 2:
            right();
            break;
            case 3:
            down();
            break;
        }
        delaybig();
    }

用户输入顺序

public void keyPressed(KeyEvent e)
{
    if(cflag<=size)
    {
        if(e.getKeyCode()==37)
            {
                entered[cflag]=0;
                cflag++;
                Keys.setText("LEFT");
                left();
            }
        else if(e.getKeyCode()==38)
            {
                entered[cflag]=1;
                cflag++;
                Keys.setText("UP");
                up();
            }
        else if(e.getKeyCode()==39)
            {
                entered[cflag]=2;
                cflag++;
                Keys.setText("RIGHT");
                right();
            }
        else if(e.getKeyCode()==40)
            {
                entered[cflag]=3;
                cflag++;
                Keys.setText("DOWN");
                down();
            }
    else
        {
            Keys.setText("INVALID");
        }
    }

使用Arrays.equals进行序列比较

if(cflag==size)
    {
        boolean check = Arrays.equals(generated, entered);
        if(check)
            {
                delaysmall();
                Keys.setText("PERFECT");
                size++;
                cflag=1;
                delaysmall();
                Keys.setText("GO AGAIN");
                delaybig();
                restart();
            }
        else
            {
                delaysmall();
                Keys.setText("FAILED");
                if(size>5)
                    {
                        delaybig();
                        restart();
                        size--;
                        cflag=1;
                    }
            }
    }

循环线

public void restart()
{
    Thread goagain =  new Thread()
    {
        @Override
        public void run()
             {
                launchframe();
             }
        };
        goagain.start();
}

我花了相当长的时间对此一无所获，所以这里是完整的代码，以防万一您怀疑错误在其他地方喜欢。

最佳答案

您调用launchFrame开始游戏的每个迭代。但是，您在launchFrame中要做很多工作，这些工作只能执行一次。您应该将该初始化代码移出launchFrame，并且只能执行一次。特别是，您不应重复调用Keys.addKeyListener(this);或添加多个窗口侦听器。
