How To Add a Start Screen To Your Javascript Game

Introduction.

Adding a start screen to your JavaScript game is a simple yet effective way to create a polished and professional experience.

It's that introductory screen where players usually see the title of the game, perhaps a "Start" button, maybe even options for settings, and it acts as a welcoming entry point before diving into the gameplay.

In this guide, I'll walk you through how to set up a start screen for your game using JavaScript, and why it’s a feature you don’t want to skip.

Why Add a Start Screen to Your Game?

First impressions matter. A start screen sets the tone for the game. It introduces players to the theme, provides them with instructions or options (like sound settings or game modes), and it just looks better.

Imagine a game that launches directly into the action without any warning. It can feel chaotic or unorganized. The start screen is like a warm welcome mat.

Now, let's jump into the actual steps for adding this feature.

Setting Up the Start Screen with HTML, CSS, and JavaScript

A start screen is basically a separate screen from your main gameplay, and the best way to structure this is with HTML for the content, CSS for the styling, and JavaScript to handle the interaction (like when the player clicks "Start" to move to the game).

1. Create the HTML Structure

Start by setting up the basic HTML structure of your page. Here’s a simple layout:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Game</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div id="start-screen">
        <h1>Welcome to My Game</h1>
        <button id="start-button">Start Game</button>
    </div>
    <canvas id="gameCanvas"></canvas>

    <script src="game.js"></script>
</body>
</html>

Enter fullscreen mode Exit fullscreen mode

In this layout:

The

will act as our start screen.

The is where the game will run once the start screen is removed.

2. Style the Start Screen with CSS.

Now, style the start screen to make it look appealing. For this example, I'll keep it simple.

#start-screen {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    height: 100vh;
    background-color: #333;
    color: #fff;
    text-align: center;
}

#gameCanvas {
    display: none;
}

#start-button {
    padding: 10px 20px;
    font-size: 18px;
    background-color: #4CAF50;
    border: none;
    color: white;
    cursor: pointer;
}

Here’s what happens:

The start screen takes up the entire viewport (height: 100vh) and centers its content.

The canvas is hidden by default since it only appears after starting the game.

The button gets a simple style to make it look like, well, a button.

3. Use JavaScript to Switch from the Start Screen to the Game

Now, for the fun part: making the transition from the start screen to the game with JavaScript.

When the "Start Game" button is clicked, the start screen will disappear, and the game will show up.

document.getElementById('start-button').addEventListener('click', function() {
    document.getElementById('start-screen').style.display = 'none';
    document.getElementById('gameCanvas').style.display = 'block';

    // Call your game initialization function here
    startGame();
});

function startGame() {
    // Initialize your game here
    console.log('Game started');
}

In this script:

I’ve added an event listener to the "Start Game" button that hides the start screen and reveals the game canvas when clicked.

The startGame() function is where you can initialize your game logic, whether it's rendering the first level or setting up game objects.

Pros and Cons of Adding a Start Screen

Pros:

  • Professionalism: A start screen instantly makes your game feel more complete and less like a draft project.
  • Player Control: It gives players a moment to prepare, review controls, or adjust settings before jumping into the action.
  • Additional Features: You can include things like sound control, difficulty settings, or even a backstory.
  • Branding Opportunities: It's a place to showcase the game's name, any logos, and even credits for the creators.

Cons:

  • Extra Development: It requires some additional coding and designing, which might not seem necessary for a small game.
  • Interrupts Quick Play: For smaller, fast-paced games, a start screen could slow down the experience if players just want to jump right in.

Conclusion.

While adding a start screen might seem like a small feature, it has a significant impact on how players perceive and interact with your game.

With all the pros and the minimal effort required, it's definitely worth considering.

Now, what do you think—will you add a start screen to your next JavaScript game, or do you prefer the simplicity of jumping straight into the action?
