}
}
public static void main(String[] args) {
GameWin gameWin = new GameWin();
gameWin.launch();
}
}
GameUtils.java
package project1;
import java.awt.*;
import java.util.ArrayList;
import java.util.List;
public class GameUtils {
//背景图片
public static Image bgImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\bg.jpg");
//boss图片
public static Image bossImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\boss.png");

//所有游戏物体的集合
public static List<GameObj> gameObjList = new ArrayList<>();
//我方子弹的集合
public static List<ShellObj> shellObjList = new ArrayList<>();
}
问题：
1.GUI中添加集合元素的用法
2.gameObjList的意义
解答：看下一节课的代码
敌方飞机的批量添加功能
1.创建EnemyObj.java
package project1;
import java.awt.*;
public class EnemyObj extends GameObj{
public EnemyObj() {
super();
}
public EnemyObj(Image img, int x, int y, int width, int height, double speed, GameWin frame) {
super(img, x, y, width, height, speed, frame);
}
@Override
public void paintSelf(Graphics gImage) {
super.paintSelf(gImage);
y += speed;
}
@Override
public Rectangle getRec() {
return super.getRec();
}
}
2.在GameUtil.java中添加敌方图片和集合
package project1;
import java.awt.*;
import java.util.ArrayList;
import java.util.List;
public class GameUtils {
//背景图片
public static Image bgImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\bg.jpg");
//boss图片
public static Image bossImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\boss.png");
//爆炸图片
public static Image explodeImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\explode\\e6.gif");
//我方战斗机图片
public static Image planeImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\plane.png");
//我方子弹图片
public static Image shellImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\shell.png");
//敌机图片
public static Image eneImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\enemy.png");
//所有游戏物体的集合
public static List<GameObj> gameObjList = new ArrayList<>();
//我方子弹的集合
public static List<ShellObj> shellObjList = new ArrayList<>();
//敌机的集合
public static List<EnemyObj> enemyObjList = new ArrayList<>();
}
3.在GameWin.java中像上一步操作中一样，添加enemyObjList和gameObjList中
x值的设置：可看视频讲解
void createObj(){
if (count % 15 == 0){
//我方子弹
GameUtils.shellObjList.add(new ShellObj(GameUtils.shellImg,planeObj.getX()+3,planeObj.getY()-16,14,29,5,this));
//通过索引把shellObjList的最后一个元素，加入到gameObjList中 ???
GameUtils.gameObjList.add(GameUtils.shellObjList.get(GameUtils.shellObjList.size()-1));
}
if (count % 15 == 0){
GameUtils.enemyObjList.add(new EnemyObj(GameUtils.eneImg,(int) (Math.random()*12)*50,0,49,36,5,this));
GameUtils.gameObjList.add(GameUtils.enemyObjList.get(GameUtils.enemyObjList.size()-1));
}
}
我方子弹与敌方飞机的碰撞检测
EnemyObj.java中修改
public void paintSelf(Graphics gImage) {
super.paintSelf(gImage);
y += speed;
for (ShellObj shellObj:GameUtils.shellObjList){
if (this.getRec().intersects(shellObj.getRec())){
System.out.println("碰撞了");
}
}
}
我方子弹与敌方飞机碰撞时的处理
我方子弹与敌方飞机碰撞时碰撞坠毁
EnemyObj.java
GameWin.java
因为鼠标移动的那个bug,所以没办法达到碰撞坠毁的效果
敌方boss的添加和移动
为敌方boss添加子弹
1.新建BulletObj类
package project1;
import java.awt.*;
public class BulletObj extends GameObj{
public BulletObj(Image img, int x, int y, int width, int height, double speed, GameWin frame) {
super(img, x, y, width, height, speed, frame);
}
@Override
public void paintSelf(Graphics gImage) {
super.paintSelf(gImage);
}
@Override
public Rectangle getRec() {
return super.getRec();
}
}
2.在GameUtils.java中添加图片和集合
//敌方子弹的集合
public static Image bulletImg = Toolkit.getDefaultToolkit().getImage("C:\\IntelliJ IDEA Community Edition 2022.2.3\\study\\src\\imgs\\bullet.png");
//敌方子弹的集合
public static List<BulletObj> bulletObjList = new ArrayList<>();
3.在GameWin.java中加入集合类中
if (count % 15 == 0){
GameUtils.bulletObjList.add(new BulletObj(GameUtils.bulletImg,bossObj.getX()+76,bossObj.getY()+85,15,25,5,this));
GameUtils.gameObjList.add(GameUtils.bulletObjList.get(GameUtils.bulletObjList.size()-1));
}
4.再回BulletObj,java中添加子弹速度
@Override
public void paintSelf(Graphics gImage) {
super.paintSelf(gImage);
y += speed;
}
我方飞机和敌方飞机子弹碰撞检测
在BulletObj.java中设置state为3
@Override
public void paintSelf(Graphics gImage) {
super.paintSelf(gImage);
y += speed;
//敌方子弹于我方飞机的碰撞检测
if (this.getRec().intersects(this.frame.planeObj.getRec())){
GameWin.state = 3;
}
}
我方飞机与敌方boss的碰撞检测
在PlaneObj.java中设置state为3
计分板的编写
1.在GameWin.java中定义游戏得分变量
2.在 GameUtil.java中绘制字符串工具类
3.在主类中替换相同代码
4.在主类中绘制计分板
5.在EnemyObj.java中检测碰撞时score++
设定游戏规则
当敌机出现100架后，Boss才出现
1.在GameWin.java中设定
2.GameWin.java中，生成一辆敌机，enemyCount就++
3.增加if判断条件，判断bossobj的生成条件
4.增加boss的子弹生成判断
5.bug:报错 --去PlaneObj.java中的碰撞检测加上判断
为敌方boss添加生命值
1.设定生命值
2.设置敌方飞机和我方子弹的碰撞检测
3.去GameWin.java中添加通关提示语
游戏的暂停功能
子弹和敌机的越界消失
因为子弹和敌机在窗口外依然被绘制，所以会降低游戏运行速度
1.子弹跑出窗口后的处理
2.敌机子弹消失判断
3.在GameWin.java中观察长度
输出：最后稳定
为敌方小飞机添加爆炸效果
1.ExplodeObj类的实现
2.GameObj.java中构造器的添加
3.ExplodeObj类中构造器的继承
4.将爆炸图放在图片数组中
2.添加爆炸图片的判断
3.在主类中添加爆炸集合类
4.在EnemyObj.java中绑定爆炸类
5.从GameWin.java添加到gameobjList中
6.在EnemyObj.java添加到removeList中
为敌方boss添加生命血条
在BossObj.java中添加
成品
