Creating a first-person shooter (FPS) game in Scratch might seem challenging at first, especially since Scratch is primarily designed for 2D projects and beginner programming. However, with some creativity, patience, and understanding of Scratch’s features, you can develop a compelling FPS experience that introduces players to game development fundamentals. In this comprehensive guide, we will explore each step involved in designing an FPS in Scratch, from setting up the environment to adding gameplay mechanics, aiming, shooting, and enhancing the visual experience. Whether you’re a beginner or an aspiring game developer, this article aims to provide clear, actionable instructions to help you bring your FPS vision to life in Scratch by 2025.

Understanding the Basics of FPS Game Design in Scratch

Before diving into the technical aspects, it’s important to understand what makes an FPS game engaging and how to adapt those elements within Scratch’s capabilities:

• Player Perspective: A first-person perspective involves the player viewing the game world through the eyes of the character. In Scratch, this can be simulated by hiding the player sprite and instead using the camera or background to create the illusion of a first-person view.
• Movement Mechanics: Players typically navigate using WASD keys or arrow keys, moving forward, backward, and strafing.
• Aiming and Shooting: The player aims at targets or enemies, often using the mouse, and shoots projectiles to eliminate them.
• Environment and Obstacles: A detailed environment with walls, corridors, or open fields enhances immersion.
• Enemy AI: Enemies that react to player actions, patrol, or attack add challenge.

Setting Up Your Scratch Project for an FPS Game

Begin by creating a new Scratch project and setting it up properly:

1. Background: Design or import backgrounds that resemble indoor or outdoor environments typical of FPS games. Use tools like Scratch’s backdrop editor or upload images.
2. Sprites: Create sprites for the player, enemies, bullets, and objects. For the first-person illusion, the player sprite can be hidden, and the scene is viewed through the environment.
3. Camera View: Since Scratch does not have a built-in 3D camera, simulate the first-person view by manipulating the background and sprite positions or using a “viewport” technique.

Creating the First-Person View

Achieving a true first-person perspective requires some creative workarounds:

• Use a ‘pseudo-3D’ effect: Create background images with perspective, such as corridors or tunnels, that give depth.
• Camera simulation: Use the camera sprite method, where the background moves relative to the player’s movements, creating the illusion of movement through a space.
• Hide the player sprite: Keep the sprite invisible so the focus remains on the environment.

For example, you can implement a scrolling background that shifts as the player moves forward or sideways, simulating walking through a corridor or open field.

Implementing Movement Controls

Player movement is fundamental to FPS gameplay. Use Scratch’s event listeners to detect key presses:

when [up arrow v] pressed
change y by 10

when [down arrow v] pressed
change y by -10

when [left arrow v] pressed
change x by -10

when [right arrow v] pressed
change x by 10

Adjust movement speed for smooth navigation. To enhance realism, implement acceleration or deceleration if desired.

Aiming and Shooting Mechanics

In an FPS, aiming typically involves the mouse. Scratch’s built-in mouse detection can be used to simulate aiming and shooting:

1. Aim: Track mouse position relative to the center of the scene to determine where the player is aiming.
2. Shooting: When the player clicks the mouse, spawn a bullet sprite that moves toward the aim point.

Implementing Shooting:

• Create a sprite called “Bullet”.
• When the mouse is clicked, clone the bullet sprite, set its starting position to the player or camera position, and determine its direction based on mouse position.
• Use a “point toward” block to aim the bullet, then move it forward each frame.

Example code snippet for the Bullet sprite:

when I start as a clone
go to [player v]
point towards [mouse-pointer v]
repeat until <touching [edge v] or 
move 15 steps
if 
then
  delete this clone
  broadcast [hit v]

Enemy Behavior and Artificial Intelligence (AI)

Enemies add challenge to your FPS game. In Scratch, AI can be simple but effective:

• Patrol along predefined paths or randomly move around the environment.
• React to player position: move toward the player when within range.
• Attack when close enough, or run away if health is low.

Basic Enemy AI Example:

when I receive [hit v]
change [health v] by -1
if 
then
  hide
  broadcast [enemy defeated v]

Implement a “see player” check using distance blocks:

if <(distance to [player v]) 
then
  point towards [player v]
  move 5 steps

Scoring, Health, and Game Progression

To make your game more engaging, add scoring, health systems, and levels:

Enhancing Visuals and User Experience

Improve immersion with visual effects:

• Use particle effects for gunfire or explosions.
• Incorporate sound effects for shooting, hits, and background music.
• Design animations for firing or enemy reactions.

Scratch’s sound library and sprite costumes support these enhancements. For example, add a gunshot sound when shooting:

when [mouse v] clicked
play sound [pop v]
create clone of [Bullet v]

Deploying and Testing Your FPS Game

Regular testing ensures mechanics work seamlessly. Use Scratch’s built-in sharing feature to upload your game and gather feedback. Additionally, optimize performance by limiting clone counts and simplifying background images.

Using Scratch’s debugging tools helps identify issues, and testing across different devices guarantees accessibility.
