今天给大家分享一个使用java编写的坦克大战小游戏，整体还是挺好玩的，通过对这款游戏的简单实现，加深对java基础的深刻理解。
一、设计思路
1.坦克大战小游戏通过java实现，其第一步需要先绘制每一关对应的地图，地图包括河流、草地、砖块、铁块等。
2.需要绘制玩家坦克、敌方坦克、以及坦克移动过程中使用到的碰撞算法，子弹与坦克之间的碰撞，
包括击中敌方坦克后的爆炸效果，通过重绘实现坦克的移动，以及各种道具的随机生成算法。
实际运行效果如下：
二、代码实现
1.首先需要将游戏中涉及到的各种对象梳理清楚，由于Java面向对象的特征，可以将一些对象公共特性抽象出来，比如将坦克抽象出一个超类，代码如下：
public abstract class Tank{
int x=0;
int y=0;
int tempX=0;
int tempY=0;
int size=32;
int direct=Constant.UP;
int speed=1;
int lives=1;
int frame=0;//控制敌方坦克切换方向的时间
boolean isAI=false;//是否自动
boolean hit;
boolean isShooting=false;
boolean isDestroyed=false;
boolean isProtected=false;
Map map;
GameMain gameMain;
Collision collision;
Bullet bullet;
int starNum=0; //星星数
public Tank(int size,int speed,Collision collision,Map map,GameMain gameMain) {
this.size=size;
this.collision=collision;
this.map=map;
this.gameMain=gameMain;
this.speed=speed;
}
public void move() {
//如果是AI坦克，在一定时间或碰撞后切换方法
if(this.isAI && gameMain.enemyStopTime>0) {
return;
}
this.tempX=this.x;
this.tempY=this.y;
if(this.isAI) {
this.frame++;
if(this.frame%100==0 || this.hit) {
this.direct=(int)(Math.random()*4);
this.hit=false;
this.frame=0;
}
}
if(this.direct==Constant.UP) {
this.tempY-=this.speed;
}else if(this.direct==Constant.DOWN) {
this.tempY+=this.speed;
}else if(this.direct==Constant.LEFT) {
this.tempX-=this.speed;
}else if(this.direct==Constant.RIGHT) {
this.tempX+=this.speed;
}
isHit();
if(!this.hit) {
this.x=this.tempX;
this.y=this.tempY;
}
}
public void isHit() {
if(this.direct==Constant.LEFT) {
if(this.x<=map.offsetX) {
this.x=map.offsetX;
this.hit=true;
}
}else if(this.direct==Constant.RIGHT) {
if(this.x>=map.offsetX+map.mapWidth-this.size) {
this.x=map.offsetX+map.mapWidth-this.size;
this.hit=true;
}
}else if(this.direct==Constant.UP) {
if(this.y<=map.offsetY) {
this.y=map.offsetY;
this.hit=true;
}
}else if(this.direct==Constant.DOWN) {
if(this.y>=map.offsetY+map.mapHeight-this.size) {
this.y=map.offsetY+map.mapHeight-this.size;
this.hit=true;
}
}
if(!this.hit) {
if(collision.tankMapCollision(this, map)) {
this.hit=true;
}
}
}
public abstract void drawTank(Graphics2D ctx2);
public void shoot(int type,Graphics2D ctx2) {
if(this.isAI && gameMain.enemyStopTime>0) {
return;
}
if(this.isShooting) {
return;
}
int tempX=this.x;
int tempY=this.y;
this.bullet=new Bullet(tempX, tempY, this.direct, gameMain, type, map, this, collision);
if(!this.isAI) {
if(this.starNum==0) {
this.bullet.speed=3;
this.bullet.fireNum=1;
}
if(this.starNum>0 && this.starNum<=3) {
this.bullet.speed+=this.starNum;
this.bullet.fireNum+=(this.starNum-1);
}
if(this.starNum>3) {
this.bullet.speed+=3;
this.bullet.fireNum+=3;
}
}
if(this.direct==Constant.UP) {
tempX = this.x + this.size/2 - this.bullet.size/2;
tempY=this.y-this.bullet.size;
}else if(this.direct==Constant.DOWN) {
tempX = this.x + this.size/2 - this.bullet.size/2;
tempY=this.y+this.bullet.size;
}else if(this.direct==Constant.LEFT) {
tempX=this.x-this.bullet.size;
tempY=this.y + this.size/2 - this.bullet.size/2;
}else if(this.direct==Constant.RIGHT) {
tempX=this.x+this.bullet.size;
tempY=this.y + this.size/2 - this.bullet.size/2;
}
this.bullet.x=tempX;
this.bullet.y=tempY;
if(!this.isAI) {
//音乐
Constant.executor.execute(new Runnable() {
@Override
public void run() {
Constant.ATTACK_AUDIO.play();
}
});
}
this.bullet.drawBullet(ctx2);
gameMain.bulletArr.add(this.bullet);
this.isShooting=true;
}
public void distroy() {
this.isDestroyed=true;
gameMain.crackArr.add(new CrackAnimation(gameMain, Constant.CRACK_TYPE_TANK, this));
if(this.isAI) {
Constant.executor.execute(new Runnable() {
@Override
public void run() {
Constant.TANK_DESTROY_AUDIO.play();
}
});
gameMain.appearEnemy--;
}else {
Constant.executor.execute(new Runnable() {
@Override
public void run() {
Constant.PLAYER_DESTROY_AUDIO.play();
}
});
this.starNum=0;
}
}
}2.坦克子类实现
public class PlayTank extends Tank{
int protectedTime = 0;//保护时间
int offsetX=0; //坦克2与坦克1的距离
int type; //玩家类型
public PlayTank(int type,Collision collision, Map map, GameMain gameMain) {
super(32, 2, collision, map, gameMain);
this.lives = 3;//生命值
this.isProtected = true;//是否受保护
this.protectedTime = 500;//保护时间
this.type=type;
}
@Override
public void drawTank(Graphics2D ctx2) {
this.hit = false;
if(this.type==1) {
ctx2.drawImage(Constant.RESOURCE_IMAGE, this.x, this.y,this.x+this.size,this.y+this.size,
Constant.POS.get("player").x+this.offsetX+this.direct*this.size, Constant.POS.get("player").y,
Constant.POS.get("player").x+this.offsetX+this.direct*this.size+this.size, Constant.POS.get("player").y+this.size, null);
}else {
ctx2.drawImage(Constant.RESOURCE_IMAGE, this.x, this.y,this.x+this.size,this.y+this.size,
Constant.POS.get("player").x+128+this.offsetX+this.direct*this.size, Constant.POS.get("player").y,
Constant.POS.get("player").x+128+this.offsetX+this.direct*this.size+this.size, Constant.POS.get("player").y+this.size, null);
}
if(this.isProtected) {
int temp=((500-protectedTime)/5)%2;
ctx2.drawImage(Constant.RESOURCE_IMAGE, this.x, this.y,this.x+this.size,this.y+this.size,
Constant.POS.get("protected").x, Constant.POS.get("protected").y+32*temp,
Constant.POS.get("protected").x+this.size, Constant.POS.get("protected").y+this.size, null);
this.protectedTime--;
if(this.protectedTime==0) {
this.isProtected=false;
}
}
}
/**
* 玩家坦克复活
* @param player
*/
public void renascenc(int playerType) {
this.lives--;
this.direct=Constant.UP;
this.isProtected=true;
this.protectedTime=500;
this.isDestroyed = false;
int temp=0;
if(playerType==1) {
temp=129;
}else {
temp=256;
}
this.x = temp + map.offsetX;
this.y = 385 + map.offsetY;
}
}3.通过子类继承父类实现玩家坦克和敌方坦克的创建，创建完后，接下来就可让坦克动起来，如下：
public void addEnemyTank(Graphics2D ctx2) {
if(enemyArr == null || enemyArr.size() >= maxAppearEnemy || maxEnemy == 0){
return;
}
appearEnemy++;
Tank objTank=null;
int rand=(int) (Math.random()*4);
if(rand==0) {
objTank=new TankEnemy0(collision, map, this);
}else if(rand==1) {
objTank=new TankEnemy1(collision, map, this);
}else if(rand==2) {
objTank=new TankEnemy2(collision, map, this);
}else if(rand==3) {
objTank=new TankEnemy3(collision, map, this);
}
enemyArr.add(objTank);
this.maxEnemy--;
map.clearEnemyNum(maxEnemy, appearEnemy,ctx2);
}4.在移动过程中，涉及到坦克与子弹，坦克与地图之间的碰撞问题，实现如下：
/**
* 坦克与地图间的碰撞
**/
public boolean tankMapCollision(Tank tank,Map map) {
//移动检测，记录最后一次的移动方向，根据方向判断+-overlap;
int tileNum=0;
int rowIndex=0;
int colIndex=0;
int overlap=3; //允许重叠的大小
//根据tank的x、y计算map的row和col
if(tank.direct==Constant.UP) {
rowIndex=(tank.tempY+overlap-map.offsetY)/map.tileSize;
colIndex=(tank.tempX+overlap-map.offsetX)/map.tileSize;
}else if(tank.direct==Constant.DOWN) {
rowIndex=(tank.tempY-overlap-map.offsetY+tank.size)/map.tileSize;
colIndex=(tank.tempX+overlap-map.offsetX)/map.tileSize;
}else if(tank.direct==Constant.LEFT) {
rowIndex=(tank.tempY+overlap-map.offsetY)/map.tileSize;
colIndex=(tank.tempX+overlap-map.offsetX)/map.tileSize;
}else if(tank.direct==Constant.RIGHT){
rowIndex=(tank.tempY+overlap-map.offsetY)/map.tileSize;
colIndex=(tank.tempX-overlap-map.offsetX+tank.size)/map.tileSize;
}
if(rowIndex>=map.hTileCount || rowIndex<0 || colIndex>=map.wTileCount || colIndex<0) {
return true;
}
if(tank.direct==Constant.UP || tank.direct==Constant.DOWN) {
int tempWidth=tank.tempX-map.offsetX-colIndex*map.tileSize+tank.size-overlap;
if(tempWidth%map.tileSize==0) {
tileNum=tempWidth/map.tileSize;
}else {
tileNum=tempWidth/map.tileSize+1;
}
for(int i=0;i<tileNum && colIndex+i<map.wTileCount;i++) {
int mapContent=map.mapLevel[rowIndex][colIndex+i];
if(mapContent==Constant.WALL || mapContent==Constant.GRID || mapContent==Constant.WATER || mapContent==Constant.HOME || mapContent==Constant.ANOTHER_HOME) {
if(tank.direct==Constant.UP) {
tank.y=map.offsetY+rowIndex*map.tileSize+map.tileSize-overlap;
}else {
tank.y=map.offsetY+rowIndex*map.tileSize-tank.size+overlap;
}
return true;
}
}
}else {
int tempHeight=tank.tempY-map.offsetY-rowIndex*map.tileSize+tank.size-overlap;
if(tempHeight%map.tileSize==0) {
tileNum=tempHeight/map.tileSize;
}else {
tileNum=tempHeight/map.tileSize+1;
}
for(int i=0;i<tileNum && rowIndex+i<map.hTileCount;i++) {
int mapContent=map.mapLevel[rowIndex+i][colIndex];
if(mapContent==Constant.WALL || mapContent==Constant.GRID || mapContent==Constant.WATER || mapContent==Constant.HOME || mapContent==Constant.ANOTHER_HOME) {
if(tank.direct==Constant.LEFT) {
tank.x=map.offsetX+colIndex*map.tileSize+map.tileSize-overlap;
}else {
tank.x=map.offsetX+colIndex*map.tileSize-tank.size+overlap;
}
return true;
}
}
}
return false;
}5.绘制界面，通过定时重绘实现，具体代码如下：
public class GameMain extends JPanel{
//int enemyNum=12;
Map map;
Num num;
int level=1;
Level tankLevel;
int gameState=Constant.GAME_STATE_MENU;
private boolean isGameOver=false;

}接下来就可运行了。
其中，切换到下一关，按键盘N，上一个按P，空格键射击。
有兴趣的可以试一试。
