如何移动形状的JFrame [英] How to move JFrame shape

问题描述

我想开发一个简单的游戏。本场比赛是关于形状。形状会移动，我们将鼠标赶上。我已经创建了一个椭圆形，椭圆形给出图形大小。但我不能反复移动这个形状。我想我需要使用定时器类。我一直在努力2小时自己，但我没有做呢。

在code;

 进口java.awt.Color中;
进口java.awt.Container中;
进口java.awt.Dimension中;
进口java.awt.Graphics;
进口java.awt.event.ActionEvent中;
进口java.awt.event.ActionListener;
进口java.awt.event.MouseEvent中;
进口java.util.Timer中;
进口java.util.TimerTask中;进口javax.swing.JFrame中;
进口javax.swing.JPanel中;公共类myshapestry扩展JFrame中实现的ActionListener {JFrame的帧=新的JFrame（Deneme）;
集装箱升;
私有静态诠释ballX = 150;
私有静态诠释BALLY = 150;
myshapestry（）{
     L = this.getContentPane（）;
     l.setLayout（NULL）;
     MyPanel面板=新MyPanel（）;
        frame.setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）;
        frame.pack（）;
        frame.setLocationRelativeTo（NULL）;
        frame.add（面板）;
        frame.setVisible（真）;
        frame.setSize（GET preferredSize（））;`` }
 公共尺寸的get preferredSize（）{
       返回新的Dimension（500,600）;
   }
   公共静态无效的主要（字符串ARGS []）{
       myshapestry TR =新myshapestry（）;
       tr.setTitle（形状游戏）;
   }   私有静态类MyPanel继承JPanel {
       保护无效paintComponent（图形G）{
           super.paintComponent方法（G）;
           g.fillOval（ballX，BALLY，50，70）;    }       公共无效的actionPerformed（ActionEvent的五）{
          ballX = ballX + 5;
          BALLY BALLY = + 10;
          重绘（）;
      }       }   }
 

我是想在myshapestry code座，这些code;

 定时器定时器=新定时器（100，myshapestry）;
t.start（）;
 

解决方案

添加像这样

  javax.swing.Timer中的定时器=新javax.swing.Timer中（100，面板）;
timer.start（）;
 

每个100毫秒的定时调用的actionPerformed（）的方法，你的 MyPanel 类

I'm trying to develop a simple game. The games is about the shapes. Shapes will move and we'll catch by mouse. I have already created a oval and given size of oval graphic. But I cannot move this shape repeatedly. I think I need to use timer class. I have been trying 2 hours myself but I didnt do yet.

The code;

    import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;


import java.util.Timer;
import java.util.TimerTask;

import javax.swing.JFrame;
import javax.swing.JPanel;



public class myshapestry extends JFrame implements ActionListener  {

JFrame frame=new JFrame("Deneme");
Container l ;
private static int ballX=150;
private static  int ballY=150;
myshapestry() {
     l=this.getContentPane();
     l.setLayout(null);
     MyPanel panel=new MyPanel();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.add(panel);
        frame.setVisible(true);
        frame.setSize(getPreferredSize());``

 }
 public Dimension getPreferredSize() {
       return new  Dimension(500,600);
   }
   public static void main (String args[]){
       myshapestry tr=new myshapestry();
       tr.setTitle("Game of Shapes");


   } 

   private static class MyPanel extends JPanel {
       protected void paintComponent(Graphics g){
           super.paintComponent(g);
           g.fillOval(ballX, ballY,50 , 70);

    }

       public void actionPerformed(ActionEvent e){
          ballX = ballX + 5;
          ballY = ballY + 10;
          repaint();
      }

       }

   }

I was trying these code in the myshapestry code block;

Timer timer=new Timer(100,myshapestry);
t.start();

解决方案

Add something like this

javax.swing.Timer timer=new javax.swing.Timer(100, panel) ;
timer.start();

Each 100msec the timer invokes actionPerformed() method of your MyPanel class
