JAVA小游戏----坦克大战(swing贴图版)（一）

一、创建JFrame窗口

public class TankFrame extends JFrame{
	
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	
	public static int Frame_Width = 500;
	public static int Frame_Height = 500;
	
	public void launchFrame() {
		//窗口大小及位置
		setSize(Frame_Width, Frame_Height);
		setLocation(1000, 100);	
		
		setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
		setVisible(true);
		setResizable(false);	
	}

	public static void main(String[] args) {
		new TankFrame().launchFrame();
	}

二、定义坦克类

set get函数eclipse可以自动生成，百度可查方法

1.Tank是个抽象父类，因为坦克会有敌我两种

public abstract class Tank {
	// 位置
	int local_x;
	int local_y;
	// 大小
	int width = 20;
	int height = 20;
	// 速度
	int speed=5;
	// 运动方向
	Direction dir;
	// 炮筒方向
	Direction pdir;
	// 坦克图片
	Image tankImage;
	//敌我
	boolean is_enemy;
	//死亡
	boolean is_Dead;
	
	public int getLocal_x() {
		return local_x;
	}
	public void setLocal_x(int local_x) {
		this.local_x = local_x;
	}
	public int getLocal_y() {
		return local_y;
	}
	public void setLocal_y(int local_y) {
		this.local_y = local_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 int getSpeed() {
		return speed;
	}
	public void setSpeed(int speed) {
		this.speed = speed;
	}
	public Direction getDir() {
		return dir;
	}
	public void setDir(Direction dir) {
		this.dir = dir;
	}
	public Direction getPdir() {
		return pdir;
	}
	public void setPdir(Direction pdir) {
		this.pdir = pdir;
	}
	public Image getTankImage() {
		return tankImage;
	}
	public void setTankImage(Image tankImage) {
		this.tankImage = tankImage;
	}
	public boolean isIs_enemy() {
		return is_enemy;
	}
	public void setIs_enemy(boolean is_enemy) {
		this.is_enemy = is_enemy;
	}
	public boolean isIs_Dead() {
		return is_Dead;
	}
	public void setIs_Dead(boolean is_Dead) {
		this.is_Dead = is_Dead;
	}
	
	public Tank(int local_x, int local_y, boolean is_enemy) {
		super();
		this.local_x = local_x;
		this.local_y = local_y;
		this.is_enemy = is_enemy;
	}
		

        public abstract void draw();//绘制相关函数（获取图片）
	public abstract void move();//移动函数
	public abstract Rectangle getRec();//获取当前位置，返回对应矩形
	public abstract Rectangle getNextRec();//获取移动后的位置，返回对应矩形	

}

Direction是自定义的一个枚举类型

public enum Direction {
	U,D,L,R,Stop
}

2.创建MyTank类，继承Tank父类

public class MyTank extends Tank {

	public MyTank(int local_x, int local_y, boolean is_enemy) {
		super(local_x, local_y, is_enemy);
		// TODO Auto-generated constructor stub
	}

	@Override
	public void draw() {
	}

	@Override
	public void move() {
	}

	@Override
	public Rectangle getRec() {
		
		return null;
	}

	@Override
	public Rectangle getNextRec() {
		
		return null;
	}

}

然后重写draw()函数，获取图片，图片放在工程根目录下，可以自行百度资源，本文结束处也会提供

@Override
public void draw() {
    setTankImage(Toolkit.getDefaultToolkit().getImage("p2tankU.gif"));
}

3.创建TankPanel类，所有的绘制在这个类中进行，可以避免闪烁

public class TankPanel extends JPanel {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
}

重写paintComponent函数，new一个MyTank，实现绘制坦克

public class TankPanel extends JPanel {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	MyTank mtank = new MyTank(100, 100, false);

	@Override
	protected void paintComponent(Graphics g) {

		super.paintComponent(g);
		g.fillRect(0, 0, TankFrame.Frame_Width, TankFrame.Frame_Height);//背景涂黑
		
		//绘制我方坦克
		mtank.draw();
		g.drawImage(mtank.getTankImage(), mtank.getLocal_x(), mtank.getLocal_y(), mtank.getWidth(), mtank.getHeight(),
				this);

	}

}

最后记得在TankFrame的launchFrame()中添加add(TP)

public class TankFrame extends JFrame{
	
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	
	public static int Frame_Width = 500;
	public static int Frame_Height = 500;
	
	TankPanel TP = new TankPanel();
	
	public void launchFrame() {
		//窗口大小及位置
		setSize(Frame_Width, Frame_Height);
		setLocation(1000, 100);	
		
		add(TP);
		
		setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
		setVisible(true);
		setResizable(false);	
	}

	public static void main(String[] args) {
		new TankFrame().launchFrame();
	}

}

效果如下

	TankPanel TP = new TankPanel();
	
	public void launchFrame() {
		//窗口大小及位置
		setSize(Frame_Width, Frame_Height);
		setLocation(1000, 100);

		super.paintComponent(g);
		g.fillRect(0, 0, TankFrame.Frame_Width, TankFrame.Frame_Height);
