Building a Retro RoboCop Game Using Python and Amazon Q CLI

As part of the Amazon Q Developer CLI #BuildGamesChallenge, I created a side-scrolling shooter game inspired by the classic RoboCop arcade feel. I used Python, Pygame, and the Amazon Q CLI to design, build, and debug my game entirely through conversational development.

Why RoboCop?

I’ve always been drawn to retro side-scrolling shooters, and RoboCop seemed like the perfect inspiration. The iconic character, combined with a simple scrolling background and shooting mechanics, gave me a focused yet fun game idea to work on.

Tools I Used

Python 3 with Pygame – the game engine
Amazon Q Developer CLI – for help with generating code and learning game dev concepts
VS Code on WSL (Ubuntu) – my development environment
Git + GitHub – for version control and project sharing

How Amazon Q Helped

Effective Prompting Techniques

Instead of asking for entire chunks of code, I learned to:

Ask Amazon Q specific questions like "What is pygame.Rect and what parameters does it take?"
Request code snippets with explanations to understand why each part matters
Use it as a rubber duck debugger when things didn’t work as expected

AI Help with Classic Programming Challenges

Amazon Q helped me tackle:

Managing game loops and frame rates
Handling user inputs (pygame.event)
Drawing sprites and bullets on screen
Creating collision logic with Rect.colliderect()
Designing menus (pause screen and start screen) using semi-transparent overlays

Automation & Debugging

Some examples of where Q saved time:

Generating boilerplate for starting the game window
Auto-scaling my RoboCop PNG sprite
Explaining how to create multiple background layers for the scrolling effect
Troubleshooting why bullets weren't appearing (helped debug pygame.draw.rect() usage)

Game Features

Here’s what the final game currently includes:

Start screen with title, instructions, and control tips
RoboCop character rendered as a PNG sprite
Scrolling background that simulates forward movement
Spacebar shooting: fire red rectangular bullets from RoboCop
Enemy spawning from the right side of the screen at timed intervals
Collision detection between bullets and enemies
Score tracking
Pause screen with resume/exit options
ESC key to exit or return to main menu

Final Output

Interesting Code Snippets

Bullet Firing & Movement

if event.key == pygame.K_SPACE:
    new_bullet = {
        "x": player_rect.x + player_rect.width,
        "y": player_rect.y + player_rect.height // 2 - 40,
        "rect": pygame.Rect(player_rect.x + player_rect.width, player_rect.y + player_rect.height // 2 - 40, 25, 5)
    }
    bullets.append(new_bullet)

# In game loop
for bullet in bullets[:]:
    bullet["x"] += bullet_speed
    bullet["rect"].x = bullet["x"]
    if bullet["x"] > SCREEN_WIDTH:
        bullets.remove(bullet)
# Enemy Spawning
enemy_spawn_timer += 1
if enemy_spawn_timer >= enemy_spawn_delay:
    enemy_y = player_rect.y
    new_enemy = {
        "x": SCREEN_WIDTH,
        "y": enemy_y,
        "rect": pygame.Rect(SCREEN_WIDTH, enemy_y, 50, 250)
    }
    enemies.append(new_enemy)
    enemy_spawn_timer = 0
# Collision Detection
for bullet in bullets[:]:
    for enemy in enemies[:]:
        if bullet["rect"].colliderect(enemy["rect"]):
            bullets.remove(bullet)
            enemies.remove(enemy)
            score += 10
            break

What I Learned

Pygame basics: window creation, screen refresh, event handling
How game objects move in frames
How to manage sprites, background, and logic in a single loop

What's Next?

Some improvements and additions I’m thinking of:

Adding sound effects (shooting, enemy hit)
Creating a health bar and lives
Level-based difficulty
Better graphics/sprites (instead of rectangles for bullets/enemies)
Add an end screen (win or game over)

Final Thoughts

This project started small, but Amazon Q CLI made it easier to explore ideas without getting stuck. It wasn’t just about getting code written. It was about learning and problem-solving through conversation.

Instead of just Googling, I could talk to Amazon Q CLI and ask why things worked, not just how. That made this retro game building challenge one of the most educational and enjoyable projects I’ve worked on.
