java窗体添加背景图片_Java项目实战之实战之天天酷跑（四）：游戏主界面

接上文，本文将实现游戏主界面，功能如下:

移动的背景图片、动态的玩家、玩家的移动功能、五种障碍物持续出现、玩家和障碍物的碰撞、暂停、继续功能。

首先，看一下整体效果：

动图实在太大，几秒钟的 Gif 就十几兆了。无奈，图片展示效果。

跳跃、得分、下落、障碍物:

碰到障碍物后，玩家被推着走。

下面，分别解释一下每个功能的逻辑：

一、创建一个显示窗体，承载游戏的主面板类。

GameFrame.java

package cn.sqc.runday.view;import javax.swing.ImageIcon;
import javax.swing.JFrame;import cn.sqc.runday.controller.GamePanel;/*** @author Huey*2020-11-27  下午12:40:22* 游戏主界面：显示窗体，承载游戏的主面板类*/public class GameFrame extends JFrame {//设置窗体宽高属性public static final int WIDTH=1500;public static final int HEIGHT=900;public GameFrame() {//2.4创建游戏面板对象，并添加到窗体上去GamePanel panel = new GamePanel();panel.action();//程序启动的方法this.addKeyListener(panel);//谁实现就监听谁this.add(panel);/**1.设置窗体基本属性*/this.setSize(WIDTH,HEIGHT);this.setLocationRelativeTo(null);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);this.setIconImage(new ImageIcon("Image/115.png").getImage());this.setUndecorated(true);this.setVisible(true);  }public static void main(String[] args) {new GameFrame();}
}

二、游戏主面板类（核心逻辑类）：

1、背景图片滚动效果

使用两张背景图片，实现背景图片滚动效果的逻辑如下：

下面用动图演示一下：

2、玩家动态效果

我国早期很有名的一部动画片《大闹天宫》，由于当时没有电脑，所以需要一帧一帧的画，随后快速播放图片，形成动态的画面（我愿称之：真·动画），并为之配音，短短10分钟的动画却要画7000到10000张原画！

而此处，我们的玩家的奔跑姿态，同理是由九张图片构成。

下面动图演示：

下面是实现玩家的（生成、移动、绘制）的基本代码，后面的障碍物的实现，也都遵循这一编写逻辑。

为更方便读懂代码，已尽力注释，若仍有不清楚的地方，欢迎留言交流。

Person.java

package cn.sqc.runday.model;import java.awt.Graphics;
import java.awt.Image;
import java.io.File;
import java.io.IOException;import javax.imageio.ImageIO;import cn.sqc.runday.view.GameFrame;/*** @author Huey* @date 2020-11-23* 玩家的实体类*/

3、几种障碍物的出现

障碍物一：螃蟹

package cn.sqc.runday.model;import java.awt.Graphics;
import java.awt.Image;
import java.awt.Paint;
import java.io.File;import javax.imageio.ImageIO;import cn.sqc.runday.view.GameFrame;public class Barrs_1 {private Image image;private Image [] images;public static final int WIDTH=100;public static final int HEIGHT=110;private int x,y;int  index;private int speed;public Barrs_1() {//     螃蟹！images = new Image[2];try {images[0]=ImageIO.read(new File("image/a2.png"));images[1]=ImageIO.read(new File("image/a4.png"));      } catch (Exception e) {// TODO: handle exception}       image = images[0];x=GameFrame.WIDTH+100;y=580;speed =30;index = 0;}public  void step() {//切换图片image =images[index++/5%images.length];x-=speed;//切换图片实现螃蟹爪子张合的动态效果的同时，使其向左移动}public void paintBarrs(Graphics g) {g.drawImage(image, x,y,WIDTH,HEIGHT, null);
}public boolean outofBounds(){return this.x <=-WIDTH;}
public Image getImage() {return image;
}
public void setImage(Image image) {this.image = image;
}
public Image[] getImages() {return images;
}
public void setImages(Image[] images) {this.images = images;
}
public int getX() {return x;
}
public void setX(int x) {this.x = x;
}
public int getY() {return y;
}
public void setY(int y) {this.y = y;
}
public int getIndex() {return index;
}
public void setIndex(int index) {this.index = index;
}
public int getSpeed() {return speed;
}
public void setSpeed(int speed) {this.speed = speed;
}
public static int getWidth() {return WIDTH;
}
public static int getHeight() {return HEIGHT;
}}

需要注意的是，在创建后，记得添加set、get方法。以便在面板类中对其障碍物进行操作。

障碍物二：宠物

与其称之障碍物，不如说它是个跟着玩家的小跟班。

package cn.sqc.runday.model;import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyListener;
import java.io.File;
import java.io.IOException;import javax.imageio.ImageIO;import cn.sqc.runday.view.GameFrame;public class Barrs_2{  //  宠物！private Image image;private Image images [] ;public static final int WIDTH= 70;public static final int HEIGHT = 60;private int x,y;int index;public Barrs_2() {init();image = images[0];x=300;y=460;}public void drop() {y ++;if(y>=460){y = 460;}}public void step(){image = images[index++/2%images.length];}public void paintBarrs(Graphics g) {g.drawImage(image, x,y,WIDTH,HEIGHT, null);}public boolean outofBounds() {return this.x<=-WIDTH;}
public void init(){images = new Image[6];for( int i=0;i<6;i++){try {images[i]=ImageIO.read(new File ("Image/"+"d"+(i+1)+".png"));} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}
}
public Image getImage() {return image;
}
public void setImage(Image image) {this.image = image;
}
public Image[] getImages() {return images;
}
public void setImages(Image[] images) {this.images = images;
}
public int getX() {return x;
}
public void setX(int x) {this.x = x;
}
public int getY() {return y;
}
public void setY(int y) {this.y = y;
}
public int getIndex() {return index;
}
public void setIndex(int index) {this.index = index;
}
public static int getWidht() {return WIDTH;
}
public static int getHeight() {return HEIGHT;
}}

障碍物三、导弹

package cn.sqc.runday.model;import java.awt.Graphics;
import java.awt.Image;
import java.io.File;import javax.imageio.ImageIO;import cn.sqc.runday.view.GameFrame;public class Barrs_3 {//       导弹！private Image image;private int x,y;public static final int WIDTH = 150;public static final int HEIGHT=70;private int speed;public Barrs_3() {try {image = ImageIO.read(new File("image/daodan.png"));} catch (Exception e) {// TODO: handle exception}x=GameFrame.WIDTH+1000;y=450;speed = 25 ;}public void step(){x-=speed;}public void paintBarrs(Graphics g) {g.drawImage(image, x, y, WIDTH, HEIGHT, null);}public boolean outofBounds(){return this.x<=-WIDTH;}public Image getImage() {return image;}public void setImage(Image image) {this.image = image;}public int getX() {return x;}public void setX(int x) {this.x = x;}public int getY() {return y;}public void setY(int y) {this.y = y;}public int getSpeed() {return speed;}public void setSpeed(int speed) {this.speed = speed;}public static int getWidth() {return WIDTH;}public static int getHeight() {return HEIGHT;}}

障碍物四：鱼叉等障碍物

package cn.sqc.runday.model;import java.awt.Graphics;
import java.awt.Image;
import java.io.File;
import java.util.Random;import javax.imageio.ImageIO;import cn.sqc.runday.view.GameFrame;public class Barrs_4 {//       鱼叉障碍物！private Image image;private Image images[];public static final int WIDTH =150;public static final int HEIGHT =350;private int x,y;public Barrs_4() {//构造方法Random random = new Random();images = new Image[4] ;try {images[0] = ImageIO.read(new File("image/11.png"));images[1]= ImageIO.read(new File("image/12.png"));images[2]= ImageIO.read(new File("image/13.png"));images[3]= ImageIO.read(new File("image/14.png"));} catch (Exception e) {// TODO: handle exception}image= images[random.nextInt(4)];x=GameFrame.WIDTH+1500;y=0;}public void step(){x-=20;}public void paintBarrs(Graphics g){g.drawImage(image, x, y, WIDTH, HEIGHT, null);}public boolean outofBounds(){return this.x<=-WIDTH;}public Image getImage() {return image;}public void setImage(Image image) {this.image = image;}public Image[] getImages() {return images;}public void setImages(Image[] images) {this.images = images;}public int getX() {return x;}public void setX(int x) {this.x = x;}public int getY() {return y;}public void setY(int y) {this.y = y;}public static int getWidth() {return WIDTH;}public static int getHeight() {return HEIGHT;}}

障碍物五、金币

在此，暂且先不写金币的动态效果。

package cn.sqc.runday.model;import java.awt.Graphics;
import java.awt.Image;
import java.io.File;
import java.io.IOException;
import java.util.Random;import javax.imageio.ImageIO;import cn.sqc.runday.view.GameFrame;/*** @author Huey*2020-11-30  下午03:44:51*金币障碍物类* */
public class Barrs_5 {private Image image;//当前显示图片public static final int WIDTH = 30;public static final int HEIGHT = 30;private int x,y;private int speed;Random random = new Random();public Barrs_5() {try {image = ImageIO.read(new File("Image/"+(random.nextInt(6) + 21) + ".png"));} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}x = GameFrame.WIDTH + 10;y = random.nextInt(600);speed = 20;}public void step(){x -= speed;}public void paintBarrs(Graphics g){g.drawImage(image, x, y, WIDTH, HEIGHT, null);}public boolean outofBounds() {return this.x<=-WIDTH;}public Image getImage() {return image;}public void setImage(Image image) {this.image = image;}public int getX() {return x;}public void setX(int x) {this.x = x;}public int getY() {return y;}public void setY(int y) {this.y = y;}public int getSpeed() {return speed;}public void setSpeed(int speed) {this.speed = speed;}public Random getRandom() {return random;}public void setRandom(Random random) {this.random = random;}public static int getWidth() {return WIDTH;}public static int getHeight() {return HEIGHT;}}

4、玩家和障碍物的碰撞逻辑

以玩家与导弹的碰撞举例：

for(int i = 0;i<barrs3.length;i++){if(person.getX() + Person.WIDTH >= barrs3[i].getX() &&person.getX() <= barrs3[i].getX()  + Barrs_3.WIDTH  &&person .getY() +Person.getHeight() >= barrs3[i].getY() &&person.getY()    <= barrs3[i].getY () + Barrs_3.HEIGHT){if(person.getX() + Person.WIDTH <= barrs3[i].getX() + Barrs_3.WIDTH){//玩家的宽度（120px）是比障碍物小的//左碰撞person.setX(barrs3[i].getX()  - Barrs_3.WIDTH);}else{//右碰撞person.setX(barrs3[i].getX()+ Barrs_3.WIDTH   );} }}

以下动图演示了玩家从右边与障碍物b发生碰撞和从左边碰撞的逻辑，上下碰撞同理。

上下左右碰撞的逻辑代码，在动图下方：

5、暂停、继续逻辑

在监听键盘按键的方法中。

代码如下：

此处的flag来源于上面程序启动的方法中，不难看出只要按了空格键，就能实现生成、移动、绘制方法的暂停，也就相当于画面的静止、游戏的暂停！

6、结束逻辑

游戏主界面代码如下：
