代碼總體上來說借鑒了尚學堂“手把手教你一小時寫出坦克大戰”（感謝），也從中加入了一些自己的想法（相對來說較少），子彈碰撞后消失，添加音效，隨機生成地形等；話不多說，直接上思維導圖（比較粗略）

窗口初始化

準備工作

首先創建一個TankWar項目，在scr相同路徑下創建images、music文件夾，將需要使用的圖片、音樂分別放在images、music中。創建一個com.tankwar（包），注意命名規范

窗口初始化

在com.tankwar中創建GamePanel類

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() {//標題setTitle("坦克大戰");//初始化窗口大小setSize(width,height);//使屏幕居中setLocationRelativeTo(null);//添加關閉事件setDefaultCloseOperation(3);//用戶不能調整setResizable(false);//使窗口可見setVisible(true);}public static void main(String[]args) {GamePanel gamePanel=new GamePanel();gamePanel.launch();} }

?運行結果

?導入窗口圖片與屏幕刷新

程序在運行時屏幕的每，對象的位置以及圖像的每一次改變都需要屏幕的一次刷新，而屏幕的每一次刷新都需要重新繪制屏幕，所以會出現閃屏現象。如果想要解決這種問題，需要運用雙緩存技術

(2條消息) Java雙緩沖技術_kkvveeerer的博客-CSDN博客_java雙緩沖

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;//定義雙緩存圖片Image offScreenImage=null;//臨時變量private int a=1;//游戲狀態 0 未開始，1 開始，2 暫停，3 失敗，4 勝利private int state=0;//游戲是否開始private boolean start=false;//窗口初始化public void launch() {//標題setTitle("坦克大戰");//初始化窗口大小setSize(width,height);//使屏幕居中setLocationRelativeTo(null);//添加關閉事件setDefaultCloseOperation(3);//用戶不能調整setResizable(false);//使窗口可見setVisible(true);/** 控制屏幕刷新時間*/while(true) {repaint();try {Thread.sleep(25);//刷新休眠時間} catch (Exception e) {e.printStackTrace();// TODO: handle exception}}}public void paint(Graphics g) {//創建和容器一樣大小的imageif(offScreenImage==null) {offScreenImage=this.createImage(width,height);}//獲得該圖片的畫布Graphics gImage=offScreenImage.getGraphics();//填充整個畫布gImage.fillRect(0,0,width,height);if(state==0) {//游戲未開始gImage.drawImage(Toolkit.getDefaultToolkit().getImage("images/interface.png"),0,0,this);}else if(state==1) {//游戲開始}else if(state==2) {//游戲暫停}else if(state==3) {//游戲失敗}else if(state==4) {//游戲勝利}g.drawImage(offScreenImage,0,0,null);}public static void main(String[]args) {GamePanel gamePanel=new GamePanel();gamePanel.launch();} }

?程序運行結果

?添加鼠標監聽器

在游戲中點擊“PLAYER”方可進入游戲，需要加入鼠標監聽器

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;//定義雙緩存圖片Image offScreenImage=null;//臨時變量private int a=1;//游戲狀態 0 未開始，1 開始，2 暫停，3 失敗，4 勝利private int state=0;//游戲是否開始private boolean start=false;//窗口初始化public void launch() {//標題setTitle("坦克大戰");//初始化窗口大小setSize(width,height);//使屏幕居中setLocationRelativeTo(null);//添加關閉事件setDefaultCloseOperation(3);//用戶不能調整setResizable(false);//使窗口可見setVisible(true);/** 控制屏幕刷新時間*/while(true) {repaint();try {Thread.sleep(25);} catch (Exception e) {e.printStackTrace();// TODO: handle exception}}}public void paint(Graphics g) {//創建和容器一樣大小的imageif(offScreenImage==null) {offScreenImage=this.createImage(width,height);}//獲得該圖片的畫布Graphics gImage=offScreenImage.getGraphics();//填充整個畫布gImage.fillRect(0,0,width,height);if(state==0) {//游戲未開始gImage.drawImage(Toolkit.getDefaultToolkit().getImage("images/interface.png"),0,0,this);//添加鼠標事件this.addMouseListener(new GamePanel.MouseMonitor());}else if(state==1) {//游戲開始}else if(state==2) {//游戲暫停}else if(state==3) {//游戲失敗}else if(state==4) {//游戲勝利}g.drawImage(offScreenImage,0,0,null);}/** 添加鼠標監聽*/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坐標范圍”state=1;start=true;}}else if(state==3||state==4) {}}}public static void main(String[]args) {GamePanel gamePanel=new GamePanel();gamePanel.launch();} }

游戲父類的編寫

方向類

游戲中坦克需要運用到“方向”，可以單獨創建一個枚舉類，或者在坦克類中定義“方向”成員變量。

/** 首先枚舉是一個特殊的class* 這個class相當于final static 修飾，不能被繼承* 他的構造方法強制被私有化* 所有的枚舉都繼承自java.lang.Enum類。由于java不支持多繼承，所以枚舉對象不能再繼承其他類*/ public enum Direction {//每個成員變量都是final static 修飾UP,LEFT,RIGHT,DOWN }

?游戲父類

游戲中的坦克、子彈、基地、墻體、爆炸圖片等元素，在繪畫到面板上的過程中，需要運用到坐標，大小、移動速度、主界面畫板。將其抽取出來，創建游戲父類

import java.awt.Graphics; import java.awt.Image; import java.awt.Rectangle; import java.awt.Toolkit;public abstract class GameObject {//游戲元素圖片Image img;//游戲元素的橫縱坐標int x;int y;//游戲元素的寬，高int width;int height;//游戲元素的移動速度int speed;//游戲元素的移動方向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;}//繼承元素繪制自己的方法public abstract void paintSelf(Graphics g);//獲取當前游戲元素的矩形,是為碰撞檢測而寫public abstract Rectangle getRec(); }

添加坦克類

Tank

四個方向移動的圖片

//向上移動時的圖片private String upImage;//向下移動時的圖片private String downImage;//向右移動時的圖片private String rightImage;//向左移動時的圖片private String leftImage;

四個方向的移動——玩家（鍵盤監聽）、人機（隨機移動）

1、墻體碰撞檢測

2、邊界碰撞檢測

3、人機碰撞檢測

4、移動

---

1、墻體碰撞檢測

/** 坦克與墻碰撞檢測*/public boolean hitWall(int x,int y) {//假設玩家坦克前進，下一個位置形成的矩形Rectangle next=new Rectangle(x,y,width,height);//地圖里所有的墻體List<Wall>walls=this.gamePanel.wallList;List<Fe>fes=this.gamePanel.feList;//判斷兩個矩形是否相交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、邊界碰撞檢測

/** 邊界與坦克碰撞檢測*/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、人機碰撞檢測

/** 人機碰撞檢測*/public boolean hitTank(int x,int y) {int a=0;//假設人機坦克前進，下一個位置形成的矩形Rectangle next=new Rectangle(x,y,width,height);//地圖里所有的人機List<Bot>bots=this.gamePanel.botList;//判斷兩個矩形是否相交for(Bot b:bots) {if(b.getRec().intersects(next)) {a++;if(a==2) {return true;}}}return false;}

?4、移動

/** 坦克移動*/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;}}

射擊——玩家（鍵盤監聽）、人機（隨機移動）

1、子彈射擊方向應與坦克移動方向一致

2、射擊子彈CD

3、射擊

---

?1、子彈射擊方向應與坦克移動方向一致

坦克坐標點為坦克圖片左上角，所以子彈初始坐標應該為坦克的坐標加上坦克高度或寬度的一半。

/** 根據方向確定頭部位置,x和y是左上角的點*/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、射擊子彈CD

/** 坦克射擊cd*/public class AttackCD extends Thread{public void run() {attackCoolDown=false;try {//休眠1秒Thread.sleep(attackCoolDownTime);//attackCoolDownTime為定義的成員變量單位為ms}catch (InterruptedException e) {e.printStackTrace();}//將攻擊功能解除冷卻狀態attackCoolDown=true;this.stop();//不是很理解}}

?3、射擊

/** 射擊*/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);//將子彈添加至子彈集合attackCoolDown=false;new AttackCD().start();}}
