Question

我正在制作一个简单的Java游戏来学习它。我想要一个方形女巫的程序，你可以点击它，它改变颜色，比我不想能够点击它8秒。我知道我不会让计时器变得更高，我这样做是为了检查是否可以在使用睡眠之前先退出计时器。

虽然是这样做我的程序卡住了我无法关闭它，所以我尝试线程，但它仍然无法正常工作。有人能告诉我我做错了吗？

import javax.swing.*;
import java.awt.*;
class ViewControll extends JFrame
{
JPanel playerPanel;
Dimension playerPlotDimension;
Plot plot00;
Thread t;

public ViewControll()
{
    playerPlotDimension=new Dimension(200,200);
    plot00 = new Plot(playerPlotDimension);
    t= new Thread(plot00);
    createAndShowGUI();
}

private void createAndShowGUI()
{
    setTitle("ALPHA 0.1");
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setLayout(new FlowLayout());
    setSize(400,400);
    setVisible(true); 
    t.start();
    add(plot00);      

}

public static void main(String args[])
{
    new ViewControll();
}


}

这里是第二类

import java.awt.Color;
import java.awt.Dimension;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.BorderFactory;
import javax.swing.JPanel;

public class Plot extends JPanel implements Runnable
{
int plotstate;
int timer;

public Plot(Dimension playerPlotDimension)
{
    plotstate =0;
    timer =0;
    setBackground(Color.GRAY);
    setPreferredSize(playerPlotDimension);
    setBorder(BorderFactory.createLineBorder(Color.DARK_GRAY,5,true));
    setToolTipText("Werkt Dit?");   
}

@Override
public void run() 
{
    addMouseListener(new MouseAdapter() 
    { 
          public void mousePressed(MouseEvent me) 
          { 

            switch (plotstate) 
            {
                case 0: setBackground(Color.GREEN);
                        plotstate = 1;
                break;
                case 1: setBackground(Color.DARK_GRAY);
                        while (timer != 8)
                        {
                        plotstate =0;
                        }
                break;
            }
          } 
    }); 

}

我这样修好了，这是一个很好的解决方案吗？

import java.awt.Color;
import java.awt.Dimension;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.BorderFactory;
import javax.swing.JPanel;


public class Plot extends JPanel implements Runnable
{
int plotstate;
int growtimer;

public Plot(Dimension playerPlotDimension)
{
    plotstate =0;
    growtimer =0;
    setBackground(Color.GRAY);
    setPreferredSize(playerPlotDimension);
    setBorder(BorderFactory.createLineBorder(Color.DARK_GRAY,5,true));
    setToolTipText("Werkt Dit?");

    addMouseListener(new MouseAdapter() 
    { 
          public void mousePressed(MouseEvent me) 
          { 

            switch (plotstate) 
            {
                case 0: setBackground(Color.GREEN);
                        plotstate = 1;
                break;
                case 1: setBackground(Color.DARK_GRAY);
                        run();
                break;
            }
          } 
    }); 


}


@Override
public void run() 
{
    while (growtimer != 8)
    {
        plotstate =0;
        try 
        {
            Thread.sleep(1000);
        } 
        catch (InterruptedException e) 
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        growtimer++;        
    }
}

如果您希望您的情节被禁用＆＃34; 8秒，为什么不存储点击时间，然后忽略后续点击，而8秒没有过去？类似的东西：

public class Plot extends JPanel implements Runnable
{
int plotstate;
long clicktime;
...
public Plot(Dimension playerPlotDimension)
{
    plotstate =0;
    growtimer =0;
    setBackground(Color.GRAY);
    setPreferredSize(playerPlotDimension);
    setBorder(BorderFactory.createLineBorder(Color.DARK_GRAY,5,true));
    setToolTipText("Werkt Dit?");

    addMouseListener(new MouseAdapter() 
    { 
          public void mousePressed(MouseEvent me) 
          { 

            switch (plotstate) 
            {
                case 0: setBackground(Color.GREEN);
                        plotstate = 1;
                        clicktime = System.currentMillis();
                break;
                case 1: setBackground(Color.DARK_GRAY);
                        if (System.currentMillis() - clicktime > 8000)
                        {
                         plotstate = 0;
                        }
                break;
            }
          } 
    }); 


}

JAVA线程似乎不起作用
