经典小游戏一-三国战纪

一、构建窗体和面板

GameFrame类

1.写一个类GameFrame，继承JFrame

2.写一个构造方法，确定窗体的特点

package day1;

import javax.swing.JFrame;

public class GameFrame extends JFrame {

    public GameFrame() {
        setTitle("a game");
        setSize(800, 600);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public static void main(String[] args) {
        GameFrame frame = new GameFrame();
        GamePanel panel = new GamePanel();
        frame.add(panel);
        frame.setVisible(true);
    }
}

GamePanal类

1.写一个类GameFrame，继承JPanal

2.写一个构造方法，确定面板的特点

package day1;

import java.awt.Color;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JPanel;

/*游戏的面板模具Panel
*/
public class GamePanel extends JPanel {

    BufferedImage bg1;

    public GamePanel() {
        // 设置背景
        try {
            bg1 = ImageIO.read(GamePanel.class.getResource("/day1/img/bg1.png"));
        } catch (IOException e) {
            e.printStackTrace();// 输出异常
        }

        // 背景色RGB
        setBackground(new Color(0, 238, 0));
    }

    /**
     * 画图方法
     */

    public void paint(Graphics g) {
        super.paint(g);
        g.drawImage(bg1, 0, 0, 800, 600, null);

    }

}
