In Eclipse, how should I change the entry point for my program. I have two separate packages each with static main methods. My original static main method found in the main package will now be called upon after running the main method found in the title package.
What I want to happen is:
Display the title screen, and If the user choice to play the game then call the Game.main()
Here are the two classes:
package game.title;
import game.main.entities.movement.MenuKeyListener;
import game.main.graphics.ImageLoader;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.FileNotFoundException;
import java.io.IOException;
import javax.swing.*;
import src.game.main.Game;
// Referenced classes of package game.main:
// MenuKeyListener, Game
public class TitleScreen extends JFrame
{
class MyCanvas extends Canvas
{
public void paint(Graphics g)
{
super.paint(g);
g.drawImage(image, 0, 0, TitleScreen.SCREENHEIGHT, TitleScreen.SCREENWIDTH, this);
}
public void update(Graphics g)
{
if(TitleScreen.toggle == 0)
{
g.clearRect(0, 0, TitleScreen.SCREENWIDTH, TitleScreen.SCREENHEIGHT);
g.drawImage(image, 0, 0, TitleScreen.SCREENHEIGHT, TitleScreen.SCREENWIDTH, this);
int xCord[] = {
322, 350, 350
};
int yCord[] = {
533, 533, 553
};
g.setColor(Color.CYAN);
g.fillPolygon(xCord, yCord, 3);
} else
if(TitleScreen.toggle == 1)
{
g.clearRect(0, 0, TitleScreen.SCREENWIDTH, TitleScreen.SCREENHEIGHT);
g.drawImage(image, 0, 0, TitleScreen.SCREENHEIGHT, TitleScreen.SCREENWIDTH, this);
int xCord[] = {
322, 350, 350
};
int yCord[] = {
600, 600, 620
};
g.setColor(Color.CYAN);
g.fillPolygon(xCord, yCord, 3);
}
}
final TitleScreen this$0;
MyCanvas()
{
this$0 = TitleScreen.this;
//super();
}
}
public static void main(String args[])
throws IOException
{
new TitleScreen();
}
public TitleScreen()
throws FileNotFoundException, IOException
{
SCALE = 2;
quit = false;
runGame = false;
setTitle("Mortem");
setSize(new Dimension(SCREENWIDTH, SCREENHEIGHT));
setLocationRelativeTo(null);
setDefaultCloseOperation(3);
setResizable(false);
MyCanvas canvas = new MyCanvas();
add(canvas);
ImageLoader loader = new ImageLoader();
image = loader.load("/Title Screen.jpg");
setVisible(true);
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(20, 20));
JLabel label = new JLabel();
label.setLocation(10, 10);
label.setSize(220, 100);
panel.add(label);
//Sound music = new Sound("/piano1.wav");
//music.play();
canvas.addKeyListener(new MenuKeyListener());
while(!check)
{
canvas.update(canvas.getGraphics());
try
{
Thread.sleep(500L);
}
catch(InterruptedException e)
{
e.printStackTrace();
}
}
if(toggle == 1){
System.out.println("BYE!");
System.exit(0);
}
else if(toggle == 0)
{
//music.stop();
Game.main(null);
System.out.println("Start Game!");
}
}
private static int SCREENWIDTH = 700;
private static int SCREENHEIGHT = 700;
private int SCALE;
private static Graphics g;
private final BufferedImage image;
private static BufferedImage titleImage;
public static int toggle = 0;
private boolean quit;
private boolean runGame;
public static boolean check = false;
}
