How to make an intro or title screen before your game starts

The main graphics console that we draw on is typically called gc
We need to make another one and then have it visible, and at some point switch to the main gc.

We make TWO graphics consoles, named appropriately.

GraphicsConsole gc = new GraphicsConsole(WINW, WINH);

GraphicsConsole gcIntro = new GraphicsConsole(500,400);

Both of these windows will show up (be visible) when the program is run!

Now we need to have only one display, and not start the main program until the first one is closed

Note: closing one window will close both (at least this happened when I tried it)

	/*** display only intro window ***/
	gc.setVisible(false);
	gcIntro.setVisible(true);

Sample program -- copy and run it

import java.awt.Color;

public class AwesomeGame {

	public static void main(String[] args) {
		new AwesomeGame();
	}
	
	/* Constants and global variables */
	static final Color NAVY = new Color(50, 50, 140);
	static final int WINW = 600;
	static final int WINH = 600;
	Font fontMain = new Font("Arial", Font.PLAIN, 24);
	Random rand = new Random();
	
	GraphicsConsole gc = new GraphicsConsole(WINW, WINH);
	
	GraphicsConsole gcIntro = new GraphicsConsole(500,400);
	
	boolean gameOver = false;
	
	AwesomeGame(){
		/*** setup each window ***/
		introSetup();
		setup();
		
		
		/*** display only intro window ***/
		gc.setVisible(false);
		gcIntro.setVisible(true);
		
		/*** now we need to wait on the intro screen until someone clicks the button or presses ESC ***/
		introButtonClick();
		
		/*** hide the instro screen and show the main window ***/
		gc.setVisible(true);
		gcIntro.setVisible(false);
		
		/*** main game loop for gc window ***/
		while(! gameOver) {
			
			drawGraphics();
			gc.sleep(30);
			
		}
		
		//the game is now over
		gc.showDialog("Thanks for playing",  "Game Over");
	}
	

	/*************************************************************** 
   	 * This method sets up everything for the introductory window.

	void introSetup() {

		gcIntro.setAntiAlias(true);
		gcIntro.enableMouse();
		gcIntro.setBackgroundColor(Color.WHITE);
		gcIntro.clear();		
		gcIntro.setFont(fontMain);
		gcIntro.setStroke(3);
		gcIntro.setLocationRelativeTo(null);
		
		/*Now write all of the instructions on the window */
		gcIntro.setColor(Color.YELLOW);
		gcIntro.fillRect(35,55,440,40);
		gcIntro.setColor(Color.BLACK);
		gcIntro.drawString("Welcome to the Game of Awesomeness", 40,80);
		gcIntro.setColor(Color.RED);
		gcIntro.drawString("In this game you will ....", 40,120);
					
	}

		gcIntro.drawRect(btn.x+3, btn.y+3, btn.width, btn.height);

		gcIntro.drawRect(btn.x, btn.y, btn.width, btn.height);
		gcIntro.drawString("Go",62,332);
		
		//This will loop until the button is clicked or "ESC" is pressed
		while (true) {
			if (gcIntro.getMouseClick()>0) {	//if someone clicks the mouse				
				if (btn.contains(gcIntro.getMousePosition())) { //get the mouse position and see if it is inside the button
					return;
				}
			} 
			
			if (gcIntro.getKeyCode() == 27) return;	 //the ESC button was pressed
			
			gcIntro.sleep(100); //if you didn't click the button, sleep and then check again.
