这里是单个图片的漂浮效果,自己修改一下图片的路径和名称就好了,看能不能帮助你

用java做游戏,怎么让背景图片滚动啊

首先需要一个大图片bg,长度为bgWeight,它作为背景,相当于一个首尾相连的画卷,人物走动的话,它就滚动

int pos=0;//它记录窗口坐标(左边)在bg的偏移;

pos=(pos+moveSpeed)%bgWeight;

然后根据pos的位置绘制背景,有可能你是绘制 bg的尾部+bg的头部 来形成完整的背景

经典代码:

public Ribbon(int movS, BufferedImage im) {

bim = im; //im就是背景图片

xImHead = 0;//当前游戏窗口左边在背景图片中的坐标

pWidth = GamePanel.WIDTH;游戏窗口宽

pHeight = GamePanel.HEIGHT;游戏窗口高

width = bim.getWidth();背景图片宽度

moveSize = movS;移动距离

}

public void draw(Graphics g) /* Consider 5 cases:考虑5种情况

// when xImHead == 0, draw only the im head

//when xImHead 0, draw the im tail and im head, or only the im tail.

//when xImHead 0, draw the im tail, or the im tail and im head

// xImHead can range between -width to width (exclusive)

*/ {

if (xImHead == 0) // draw im head at (0,0)//情况1

{

drawRibbon(g, bim, 0, pWidth, 0, pWidth);

}

else if ((xImHead 0) (xImHead pWidth)) {//情况2

// draw im tail at (0,0) and im head at (xImHead,0)

drawRibbon(g, bim, 0, xImHead, width - xImHead, width); // im tail

drawRibbon(g, bim, xImHead, pWidth, 0, pWidth - xImHead); // im head

}

else if (xImHead = pWidth) // only draw im tail at (0,0),情况3

{

drawRibbon(g, bim, 0, pWidth,

width - xImHead, width - xImHead + pWidth); // im tail

}

else if ((xImHead 0) (xImHead = pWidth - width)) {//情况4

drawRibbon(g, bim, 0, pWidth, -xImHead, pWidth - xImHead); // im body

}

else if (xImHead pWidth - width) { //情况5

// draw im tail at (0,0) and im head at (width+xImHead,0)

drawRibbon(g, bim, 0, width + xImHead, -xImHead, width); // im tail

drawRibbon(g, bim, width + xImHead, pWidth,

0, pWidth - width - xImHead); // im head

}

} // end of display()

怎么在GUI中用键盘控制图片运动?java问题?

废话不多说,直接上代码

------------------------------------------

import java.awt.Color;

import java.awt.Point;

import java.awt.event.KeyAdapter;

import java.awt.event.KeyEvent;

import javax.swing.Icon;

import javax.swing.ImageIcon;

import javax.swing.JFrame;

import javax.swing.JLabel;

public class MoveImage {

JFrame win;

Icon img;

JLabel lb;

public MoveImage() {

win = new JFrame("MoveImage");

// 加载图片

img = new ImageIcon(getClass().getResource("img.gif"));

lb = new JLabel();

// 装载图片

lb.setIcon(img);

win.setBounds(200, 0, 400, 300);

// 响应键盘上的键按下事件

win.addKeyListener(new KeyAdapter() {

@Override

public void keyPressed(KeyEvent e) {

move(e.getKeyCode());

}

});

win.add(lb);

win.setBackground(Color.WHITE);

win.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

win.setVisible(true);

win.validate();

}

/**

* 移动图片, 只处理上下左右4个方向键,其它的不处理

*

* @param keyCode

* 按下的键盘上的键的键值

*/

void move(int keyCode) {

// 记下原来的位置

Point pos = lb.getLocation();

switch (keyCode) {

case KeyEvent.VK_UP:// 上方向键

pos.y -= 1;

break;

case KeyEvent.VK_RIGHT:// 右方向键

pos.x += 1;

break;

case KeyEvent.VK_DOWN:// 下方向键

pos.y += 1;

break;

case KeyEvent.VK_LEFT:// 左方向键

pos.x -= 1;

}

// 设置新位置

lb.setLocation(pos);

lb.validate();

}

/**

* @param args

*/

public static void main(String[] args) {

new MoveImage();

}

}

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.
