How to Make a City Builder Game with Rosebud AI

Ever imagined designing an entire city—from streets and skyscrapers to vibrant neighborhoods—without dealing with complicated code?

That's exactly what we did with Rosebud AI to create "City Lifer", a dynamic, fully interactive city-building simulator.

All it took was describing the vision, and Rosebud handled the rest.

Curious about how easy it can be? Let us show you step-by-step.

Step 1: Setting the Scene

First, head over to Rosebud AI's platform.

Begin your journey by imagining the kind of city you're building:

Prompt Example:

• "Generate a vibrant, modern city environment"

Rosebud takes your description and starts generating the core setup, including realistic lighting, sky effects, and the groundwork for your city’s layout.

Step 2: Designing Your City Layout

Now, let's make the city more structured and believable:

Prompt Examples:

• "Arrange city blocks in a grid pattern, each block separated by wide streets”.
• “Add a variety of building sizes, with taller skyscrapers in the downtown area and smaller buildings further out."

Rosebud uses these instructions to generate distinct city blocks, streets, and diverse buildings automatically.

Step 3: Adding Life with NPCs and Details

A city builder isn't just about buildings; it’s about life.

Let's populate your city with this series of prompts:

Prompt Examples:

• "Include some NPCs with diverse clothing colors and natural walking patterns”.
• “NPCs should avoid collisions with buildings and each other”.
• “Add street lights that flicker subtly and fireflies near parks and green areas for extra ambiance."

Rosebud AI seamlessly integrates these dynamic elements, instantly giving life and realism to your city.

Step 4: Camera Views and Interaction

To explore your city from various perspectives, specify camera behaviors:

Prompt Examples:

• "Set up a camera view of a bird's-eye view rotating gently around the city center”
• “Set up a personal view where users can walk through the streets using WASD controls”

Rosebud AI automatically handles the camera configurations and controls, offering intuitive navigation around your creation.

Step 5: Fine-Tuning the Vibe

If something feels off or needs extra polishing, don’t hesitate to iterate:

Prompt Example:

• "Make street surfaces darker for contrast, slightly increase NPC walking speed, and enhance building materials to reflect more city lights at night."

With a simple prompt, Rosebud AI refines your city, allowing quick and effortless tweaking until you're fully satisfied.

Publishing Your City Builder

Once you're thrilled with your city, simply click 'Publish.'
