java实现坦克大战
2024-05-11 12:41:14
代码总体上来说借鉴了尚学堂“手把手教你一小时写出坦克大战”（感谢），也从中加入了一些自己的想法（相对来说较少），子弹碰撞后消失，添加音效，随机生成地形等；话不多说，直接上思维导图（比较粗略）

窗口初始化
准备工作
首先创建一个TankWar项目，在scr相同路径下创建images、music文件夹，将需要使用的图片、音乐分别放在images、music中。创建一个com.tankwar（包），注意命名规范
窗口初始化
在com.tankwar中创建GamePanel类
import javax.swing.JFrame;
public class GamePanel extends JFrame{//窗口大小private int width=1260;private int height=800;//窗口初始化public void launch() {//标题setTitle("坦克大战");//初始化窗口大小setSize(width,height);//使屏幕居中setLocationRelativeTo(null);//添加关闭事件setDefaultCloseOperation(3);//用户不能调整setResizable(false);//使窗口可见setVisible(true);}public static void main(String[]args) {GamePanel gamePanel=new GamePanel();gamePanel.launch();}
}运行结果
导入窗口图片与屏幕刷新
程序在运行时屏幕的每，对象的位置以及图像的每一次改变都需要屏幕的一次刷新，而屏幕的每一次刷新都需要重新绘制屏幕，所以会出现闪屏现象。如果想要解决这种问题，需要运用双缓存技术
(2条消息) Java双缓冲技术_kkvveeerer的博客-CSDN博客_java双缓冲
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;import javax.swing.JFrame;
public class GamePanel extends JFrame{//窗口大小private int width=1260;private int height=800;//定义双缓存图片Image offScreenImage=null;//临时变量private int a=1;//游戏状态 0 未开始，1 开始，2 暂停，3 失败，4 胜利private int state=0;//游戏是否开始private boolean start=false;//窗口初始化public void launch() {//标题setTitle("坦克大战");//初始化窗口大小setSize(width,height);//使屏幕居中setLocationRelativeTo(null);//添加关闭事件setDefaultCloseOperation(3);//用户不能调整setResizable(false);//使窗口可见setVisible(true);/** 控制屏幕刷新时间*/while(true) {repaint();try {Thread.sleep(25);//刷新休眠时间} catch (Exception e) {e.printStackTrace();// TODO: handle exception}}}public void paint(Graphics g) {//创建和容器一样大小的imageif(offScreenImage==null) {offScreenImage=this.createImage(width,height);}//获得该图片的画布Graphics gImage=offScreenImage.getGraphics();//填充整个画布gImage.fillRect(0,0,width,height);if(state==0) {//游戏未开始gImage.drawImage(Toolkit.getDefaultToolkit().getImage("images/interface.png"),0,0,this);}else if(state==1) {//游戏开始}else if(state==2) {//游戏暂停}else if(state==3) {//游戏失败}else if(state==4) {//游戏胜利}g.drawImage(offScreenImage,0,0,null);}public static void main(String[]args) {GamePanel gamePanel=new GamePanel();gamePanel.launch();}
}
程序运行结果
添加鼠标监听器
在游戏中点击“PLAYER”方可进入游戏，需要加入鼠标监听器
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Point;
import java.awt.Toolkit;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;import javax.swing.JFrame;
public class GamePanel extends JFrame{//窗口大小private int width=1260;private int height=800;//定义双缓存图片Image offScreenImage=null;//临时变量private int a=1;//游戏状态 0 未开始，1 开始，2 暂停，3 失败，4 胜利private int state=0;//游戏是否开始private boolean start=false;//窗口初始化public void launch() {//标题setTitle("坦克大战");//初始化窗口大小setSize(width,height);//使屏幕居中setLocationRelativeTo(null);//添加关闭事件setDefaultCloseOperation(3);//用户不能调整setResizable(false);//使窗口可见setVisible(true);/** 控制屏幕刷新时间*/while(true) {repaint();try {Thread.sleep(25);} catch (Exception e) {e.printStackTrace();// TODO: handle exception}}}public void paint(Graphics g) {//创建和容器一样大小的imageif(offScreenImage==null) {offScreenImage=this.createImage(width,height);}//获得该图片的画布Graphics gImage=offScreenImage.getGraphics();//填充整个画布gImage.fillRect(0,0,width,height);if(state==0) {//游戏未开始gImage.drawImage(Toolkit.getDefaultToolkit().getImage("images/interface.png"),0,0,this);//添加鼠标事件this.addMouseListener(new GamePanel.MouseMonitor());}else if(state==1) {//游戏开始}else if(state==2) {//游戏暂停}else if(state==3) {//游戏失败}else if(state==4) {//游戏胜利}g.drawImage(offScreenImage,0,0,null);}/** 添加鼠标监听*/private class MouseMonitor extends MouseAdapter{@Overridepublic void mouseClicked(MouseEvent e) {Point p=new Point(e.getX(),e.getY());if(!start&&state==0) {if(p.x>450&&p.x<750&&p.y>400&&p.y<480) {//“PLAYER X，Y坐标范围”state=1;start=true;}}else if(state==3||state==4) {}}}public static void main(String[]args) {GamePanel gamePanel=new GamePanel();gamePanel.launch();}
}
游戏父类的编写
方向类
游戏中坦克需要运用到“方向”，可以单独创建一个枚举类，或者在坦克类中定义“方向”成员变量。
/** 首先枚举是一个特殊的class* 这个class相当于final static 修饰，不能被继承* 他的构造方法强制被私有化* 所有的枚举都继承自java.lang.Enum类。由于java不支持多继承，所以枚举对象不能再继承其他类*/
public enum Direction {//每个成员变量都是final static 修饰UP,LEFT,RIGHT,DOWN
}游戏父类
游戏中的坦克、子弹、基地、墙体、爆炸图片等元素，在绘画到面板上的过程中，需要运用到坐标，大小、移动速度、主界面画板。将其抽取出来，创建游戏父类
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Rectangle;
import java.awt.Toolkit;public abstract class GameObject {//游戏元素图片Image img;//游戏元素的横纵坐标int x;int y;//游戏元素的宽，高int width;int height;//游戏元素的移动速度int speed;//游戏元素的移动方向Direction direction;//引入主界面GamePanel gamePanel;public GameObject() {}public GameObject(String img,int x,int y,GamePanel gamePanel) {this.img=Toolkit.getDefaultToolkit().getImage(img);this.x=x;this.y=y;this.gamePanel=gamePanel;}public Image getImag() {return img;}public void setImg(String img) {this.img=Toolkit.getDefaultToolkit().getImage(img);}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 getWidth() {return width;}public void setWidth(int width) {this.width = width;}public int getHeight() {return height;}public void setHeight(int height) {this.height = height;}public double getSpeed() {return speed;}public void setSpeed(int speed) {this.speed = speed;}public Direction getDirection() {return direction;}public void setDirection(Direction direction) {this.direction = direction;}public GamePanel getGamePanel() {return gamePanel;}public void setGamePanel(GamePanel gamepanel) {this.gamePanel = gamePanel;}//继承元素绘制自己的方法public abstract void paintSelf(Graphics g);//获取当前游戏元素的矩形,是为碰撞检测而写public abstract Rectangle getRec();
}添加坦克类
Tank

四个方向移动的图片
//向上移动时的图片private String upImage;//向下移动时的图片private String downImage;//向右移动时的图片private String rightImage;//向左移动时的图片private String leftImage;四个方向的移动——玩家（键盘监听）、人机（随机移动）
1、墙体碰撞检测
2、边界碰撞检测
3、人机碰撞检测
4、移动
1、墙体碰撞检测
/** 坦克与墙碰撞检测*/public boolean hitWall(int x,int y) {//假设玩家坦克前进，下一个位置形成的矩形Rectangle next=new Rectangle(x,y,width,height);//地图里所有的墙体List<Wall>walls=this.gamePanel.wallList;List<Fe>fes=this.gamePanel.feList;//判断两个矩形是否相交for(Wall w:walls) {if(w.getRec().intersects(next)) {return true;}}for(Fe f:fes) {if(f.getRec().intersects(next)) {return true;}}return false;}2、边界碰撞检测
/** 边界与坦克碰撞检测*/public boolean moveToBorder(int x,int y) {if(x<10) {return true;}else if(x>this.gamePanel.getWidth()-width) {return true;}if(y<30) {return true;}else if(y>this.gamePanel.getHeight()-height) {return true;}return false;}3、人机碰撞检测
/** 人机碰撞检测*/public boolean hitTank(int x,int y) {int a=0;//假设人机坦克前进，下一个位置形成的矩形Rectangle next=new Rectangle(x,y,width,height);//地图里所有的人机List<Bot>bots=this.gamePanel.botList;//判断两个矩形是否相交for(Bot b:bots) {if(b.getRec().intersects(next)) {a++;if(a==2) {return true;}}}return false;}4、移动
/** 坦克移动*/public void leftWard() {direction=Direction.LEFT;setImg(leftImage);if(!hitWall(x-speed,y)&&!moveToBorder(x-speed,y)&&alive&&!hitTank(x-speed,y)) {this.x-=speed;}}public void rightWard() {direction=Direction.RIGHT;setImg(rightImage);if(!hitWall(x+speed,y)&&!moveToBorder(x+speed,y)&&alive&&!hitTank(x+speed,y)) {this.x+=speed;}}public void upWard() {direction=Direction.UP;setImg(upImage);if(!hitWall(x,y-speed)&&!moveToBorder(x,y-speed)&&alive&&!hitTank(x,y-speed)) {this.y-=speed;}}public void downWard() {direction=Direction.DOWN;setImg(downImage);if(!hitWall(x,y+speed)&&!moveToBorder(x,y+speed)&&alive&&!hitTank(x-speed,y+speed)) {this.y+=speed;}}射击——玩家（键盘监听）、人机（随机移动）
1、子弹射击方向应与坦克移动方向一致
2、射击子弹CD
3、射击
1、子弹射击方向应与坦克移动方向一致
坦克坐标点为坦克图片左上角，所以子弹初始坐标应该为坦克的坐标加上坦克高度或宽度的一半。
/** 根据方向确定头部位置,x和y是左上角的点*/public Point getHeadPoint() {switch(direction) {case UP:return new Point(x+width/2,y);case LEFT:return new Point(x,y+height/2);case DOWN:return new Point(x+width/2,y+height);case RIGHT:return new Point(x+width,y+height/2);default:return null;}}2、射击子弹CD
/** 坦克射击cd*/public class AttackCD extends Thread{public void run() {attackCoolDown=false;try {//休眠1秒Thread.sleep(attackCoolDownTime);//attackCoolDownTime为定义的成员变量单位为ms}catch (InterruptedException e) {e.printStackTrace();}//将攻击功能解除冷却状态attackCoolDown=true;this.stop();//不是很理解}}3、射击
/** 射击*/public void attack() {Point p=getHeadPoint();if(attackCoolDown&&alive) {Bullet bullet=new Bullet("images/bullet/bulletGreen.gif",p.x-10,p.y-10, direction, this.gamePanel);this.gamePanel.bulletList.add(bullet);//将子弹添加至子弹集合attackCoolDown=false;new AttackCD().start();}}总

玩家类继承坦克类，在父类的基础上只需要添加键盘监听器即可
