java 中移动图片，并且在按键盘的“回车”时，切换到另外一张图片！！请在我下面的代码改进！！！谢谢！！
你好，按照你的要求代码如下，修改了三处

简单说明一下，就是加了一个标识boolean，用true/false来表示显示第一张/第二张图片
import java.awt.*;
import java.awt.event.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.*;
public class zhandou extends JFrame implements KeyListener {
Image roleImage, Image1;
int x, y;
public zhandou() {
super("MOVE");
Container c = getContentPane();
setSize(320, 240);
setVisible(true);
loadImage();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// setFocusable(true);
addKeyListener(this);
}
boolean key = true;// 加这样一个标识，true是第一张图片，false为第二张图片
public void paint(Graphics g) {
super.paint(g);
// drawRole(g);
if (key) {// 根据标识判断需要显示的图片
g.drawImage(roleImage, x, y, this);
} else {
g.drawImage(Image1, x, y, this);
}
}
public void loadImage() {
ImageIcon icon = new ImageIcon("tupian/草地.jpg");
roleImage = icon.getImage();
ImageIcon ic = new ImageIcon("tupian/right.gif");
Image1 = ic.getImage();
}
class Thread1 extends Thread {
}
/*
* private void drawRole(Graphics g) { g.drawImage(roleImage,100,100,this);
* }
*/
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_UP)
y = y - 5;
else if (e.getKeyCode() == KeyEvent.VK_DOWN)
y = y + 5;
else if (e.getKeyCode() == KeyEvent.VK_RIGHT)
x = x + 5;
else if (e.getKeyCode() == KeyEvent.VK_LEFT)
x = x - 5;
else if (e.getKeyCode() == KeyEvent.VK_ENTER)
key = !key;// 切换标识状态
repaint();
}
public void keyReleased(KeyEvent e) {
}
public void keyTyped(KeyEvent e) {
}
public static void main(String args[]) {
new zhandou();
}
}
java让图片的移动
java 做游戏一般都是在手机上的
专门有个微型JAVA 叫 J2ME
里面有游戏API 你学学这个就明白了
一段图片从右到左移动的JAVASCRPT代码,帮忙改成图片从上到下移动
...想要图片从上到下.?,是自动移动吗？
是的话，用Marquee这个标签就行了,里面有控制方向的属性-
-,没必要写个方法
JAVA 如何把一个图形移动到另外一个位置，代码快完成，就差关键部分
我要分，赶快采纳哦......
public void run() {
/* Begin section C. */
// Increment c from 1 to 100.
for (int c = 1; c = 1000; c++) {
// Pause this frame for 250 milliseconds before drawing the next
// frame.
try {
Thread.sleep(250);
} catch (InterruptedException i) {
System.exit(1);
}
// 我以下添加
carbodylocation.changeLocation(new Location(carbodylocation.getVertical() - c, carbodylocation.getHorizontal() + c));
windowLocation.changeLocation(new Location(windowLocation.getVertical() - c, windowLocation.getHorizontal() + c));
window2Location.changeLocation(new Location(window2Location.getVertical() - c, window2Location.getHorizontal() + c));
wheellocation.changeLocation(new Location(wheellocation.getVertical() - c, wheellocation.getHorizontal() + c));
tireLocation.changeLocation(new Location(tireLocation.getVertical() - c, tireLocation.getHorizontal() + c));
tire2Location.changeLocation(new Location(tire2Location.getVertical() - c, tire2Location.getHorizontal() + c));
wheel2Location.changeLocation(new Location(wheel2Location.getVertical() - c, wheel2Location.getHorizontal() + c));
// 以上我添加
// Draw the frame.
repaint();
}
/* End section C. */
}
怎么编写java程序实现图片的移动(最好有例子)
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
public class DrawTest extends JFrame {
private int x = 50;
private int y = 50;
private Image offScreenImage = null;
@Override
public void paint(Graphics g) {
Color c = g.getColor();
g.setColor(Color.BLACK);
g.fillOval(x, y, 30, 30);
g.setColor(c);
}
public void update(Graphics g) {
if (offScreenImage == null) {
offScreenImage = this.createImage(500, 500);
}
Graphics gOffScreen = offScreenImage.getGraphics();
Color c = gOffScreen.getColor();
gOffScreen.setColor(Color.GREEN);
gOffScreen.fillRect(0, 0, 500, 500);
gOffScreen.setColor(c);
paint(gOffScreen);
g.drawImage(offScreenImage, 0, 0, null);
}
public static void main(String[] args) {
DrawTest d = new DrawTest();
}
public DrawTest() {
init();
addKeyListener(new KeyAdapter() {
public void keyPressed(final KeyEvent e) {
int code = e.getKeyCode();
switch (code) {
case KeyEvent.VK_UP:
y -= 5;
break;
case KeyEvent.VK_RIGHT:
x += 5;
break;
case KeyEvent.VK_DOWN:
y += 5;
break;
case KeyEvent.VK_LEFT:
x -= 5;
break;
}
}
});
}
public void init() {
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
this.setBackground(Color.GREEN);
this.setResizable(false);
this.setBounds(140, 140, 500, 500);
this.setVisible(true);
MyThread mt = new MyThread();
new Thread(mt).start();
}
class MyThread implements Runnable {
public void run() {
while (true) {
repaint();
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
以上
java语言里怎么让图象移动到指定位置啊,最好用一小段代码说明.
改变规制时候的X Y就行了.伪代码如下.
int x =0,y=0,;
x++; y++;
g.drawImage( "图片信息" , x, y,锚点);
大概就这样图片就动了.你想移动到哪加个判断就行了.
