Creating a Launcher with Buttons

To start off, we need to create a launcher for our game. In the previous episode, we created a launcher with buttons that didn’t work. Now, we’re going to make those buttons functional. But before we do that, let’s move the launcher to a new package called “GUI” to keep our code organized.

Now, let’s focus on adding functionality to the “Play” button. We will add an action listener to the button, which will perform a specific action when the button is clicked. In our case, we want to print a line that says “Play”.

play.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        System.out.println("Play");
    }
});

Similarly, we can add action listeners to the other buttons for “Options”, “Help”, and “Quit” as well. For now, let’s just print a line for each button to verify that they are working.

Extending the Launcher

Now, let’s extend our launcher to create a new class called “Options”. This class will be responsible for displaying a window with additional options for our game. We will add a dropdown menu to select the game resolution as an example option.

To create the dropdown menu, we’ll use the “Choice” class in Java. We’ll add different resolution options to the dropdown menu, such as 640×480, 1024×768, and 800×600.

Next, we’ll set the default selected resolution and create two methods, “getGameWidth” and “getGameHeight”, to return the selected resolution’s width and height values.

Updating the Game Resolution

To update the game resolution based on the selected option, we’ll need to modify the “runGame” method in the game code. We’ll use the “getGameWidth” and “getGameHeight” methods from the “Options” class to set the game resolution before launching it.

Next Steps: Save User Preferences and Help Section

In the next episode, we’ll add functionality to save the user’s selected resolution preference. This way, the game will remember the chosen resolution each time it is launched.

We’ll also add a help section to provide users with information and instructions on how to play the game.
