Question

好的，我需要很多帮助，所以无论有什么建议都会非常感激！我正在尝试编写一个跑步/跳跃游戏，玩家/球必须尽可能快地避开积木到达终点线。现在，我的两个主要问题是跳跃动作和创建计时器。当我的玩家跳跃时，它会上升，然后下降。我在Circle类中包含了以下代码：

public void horiz(int val){

    for(int c = 0; c<val+1; c++){
        x++;
        repaint();}
}
public void vert(int val){
    y += val;
}
public void down(int val){
    y += val;
}

然后通过按钮执行：

public void actionPerformed(ActionEvent e){
    if(e.getSource() instanceof Button){
        if(e.getSource() == run)
            player.horiz(10);
        else if (e.getSource()== jump){
            player.vert(-10);
            }
        repaint();
        collision();
}

为了让玩家上升，然后退缩，我试过了......

public void actionPerformed(ActionEvent e){
    if(e.getSource() instanceof Button){
        if(e.getSource() == run)
            player.horiz(10);
        else if (e.getSource()== jump){
            player.vert(-10);
            repaint();
            player.down(10);
            }
        repaint();
        collision();
}

但是我觉得我需要等几秒才能回来。我已经阅读了一些关于swing，util和机器人定时器的内容，但我不知道在这里实现它们/在何处实现它们。

我的另一个问题是创建一个计时器，显示自游戏开始以来经过的时间。我的事情这可以与跳跃计时器类似地执行，但是，再次，我不确定我应该使用哪种类型的计时器。如果我是对的，我不能使用swing，因为我的程序是用AWT编写的？请原谅可怕的颜色，我仍在搞清楚基础知识。非常感谢你给我的任何帮助建议！：）
