Forget Code, Use ‘Vibe Code’: How to Create Your First Game with Rosebud AI

Ever had a brilliant idea for a video game? A flash of inspiration for a world you’d love to explore, a character you need to bring to life, or a story that just has to be told?

For many of us, the dream often ends there. When you think about programming, 3D modeling, and asset pipelines, the task seems overwhelming.

What if you could build a game not with lines of C++ or Python, but with vibes? What if you could describe the world, the mood, and the gameplay like you were telling a friend about a dream?

Welcome to the future of game creation. Welcome to Rosebud AI, where you don’t write code—you write “Vibe Code.”

What is Rosebud AI, and what is “Vibe Code”?

Rosebud AI is a groundbreaking platform that uses generative AI to turn your text prompts into playable games and interactive experiences. It’s designed for storytellers, artists, and dreamers, not just seasoned developers.

The magic behind it is what we’re calling “Vibe Code.”

Vibe Code is the art of using natural language—descriptive words, moods, and scenarios—to instruct an AI. Instead of typing function player. Jump (height: 10), you type:

“Make the character a nimble astronaut who can do a floaty, low-gravity jump.”

Instead of meticulously placing assets, you describe the scene:

“Create a cozy, rainy-day cafe where you serve coffee to sad ghosts. The art style is Ghibli-inspired, with warm lighting and steam on the windows.”

Your idea, your feeling, and your vibe become the source code. The AI interprets this Vibe Code to generate characters, environments, assets, and even game logic. It’s a conversation, not a command line.

Your First Rosebud AI Game: A Step-by-Step Guide for Quick Setup

Are you prepared to take on the role of a Vibe Coder? Let’s build your first game. It’s faster and more fun than you can imagine.

  • Step 1: Head to the Studio and Dream Up Your Vibe

First, navigate to the Rosebud AI website and log in to your account. A simple prompt box will greet you. This box is where the magic begins.

This space is your canvas. Don’t be shy. Think about the core of your game idea. What is the genre? What is the art style? What does the player do?

Let’s start with a fun, descriptive prompt.

Example Vibe Code Prompt:

“A 3D third-person platformer game. The player is a charming, little mushroom knight with a leaf for a shield. The world is a magical, oversized forest floor with glowing moss and giant, bouncy toadstools. The goal is to collect three shiny dewdrops.”

  • Step 2: Generate Your World

Press “Generate” to let Rosebud perform its magic. The AI will parse your Vibe Code and begin building the scene. It will generate

The character: A mushroom knight, just as you described.

The Environment: A lush forest floor, complete with the assets you mentioned.

The Goal: It will likely place the collectible “dewdrops” around the level.

Basic Logic: They will understand this is a platformer and give your character basic movement controls.

In a minute or two, you will have a playable, interactive skeleton of your game.

  • Step 3: Refine and Iterate with Conversational Commands

This is where you truly become a game director. Your first generation is a starting point, not the final product. Now you can “talk” to your game to change it.

Click on an object or just type in the chat box. Treat the AI like a creative partner.

Want to change the character?

“Change the mushroom knight’s cap to be red with white spots.”

Want to alter the environment?

“Make the sky a perpetual twilight purple and add a second moon.”

Need more interactivity?

“When the player touches a bouncy toadstool, they should launch high into the air.”

Want to add an NPC (non-player character)?

“Add a wise old owl NPC sitting on a branch. When the player gets close, he should say, ‘The dewdrops shimmer brightest in the darkest corners!”

This continual back-and-forth is the core of Vibe Coding. You see something, you have a new idea, you describe it, and the AI makes it happen.

  • Step 4: Add Logic and Win/Loss Conditions

A game needs rules. You can add them with a simple Vibe code, too.

Winning:

“Once the player collects all three dewdrops, display a ‘You Win!’ message and play a victory sound.”

Losing (optional):

“Add some grumpy slug enemies that patrol the ground. If they touch the player, reset the level.”

  • Step 5: Play and Share!

At any point, you can click the “Play” button to test your creation. Run around, jump on the toadstools, and see how it feels. When you’re pleased with your mini-game, you can generate a shareable link to send to your friends.

Just like that, you’ve gone from a simple idea to a playable, shareable game. You didn’t write a single line of traditional code, but you directed every creative decision.

If you’re interested in learning more about Rosebud AI, check out their official YouTube channel for more tutorials.

An example of a game created by MystyDev using RosebudAI.

This video, “AI made me a HORROR game in 1 day!,” demonstrates how Rosebud AI can be used to create video games from simple text prompts. The creator first shows how to generate a basic paper plane flying game by describing the desired gameplay. They then showcase the process of refining the game by adding new features like improved controls, a boost mechanic, and updated visuals, all through conversational commands with the AI.

The video further explores Rosebud AI’s capabilities by creating a more complex horror shooter game, detailing the step-by-step process of implementing a character controller, weapon systems, a randomly generated map, and enemy AI. The creator highlights the AI’s ability to generate 3D models and textures from text and even debug issues based on screenshots and descriptions, ultimately building a complete game within a single day.

Tips for Effective “Vibe Coding”

Be Specific with Adjectives: Don’t just say “a forest.” Say “a spooky, fog-filled forest with gnarled, leafless trees.”

Think in Layers: Start with the big picture (environment, mood), then add characters, then add interactive objects, and finally, add game rules.

Use References: Mentioning styles like “pixel art,” “Ghibli-inspired,” or “cyberpunk” gives the AI a powerful creative shortcut.

Experiment! The best part about Rosebud is the low cost of trying something new. Don’t like the result? Just change the prompt. Ask, “What if…?” and see what happens!

The limit to creating games is no longer technical skill but rather your imagination. Rosebud AI and the concept of “Vibe Code” empower anyone to be a creator.

You can explore a vast array of prompts to expand your creative abilities. Here are some fresh directions you could take:

World-Building Prompts

  • Imagine a bunch of islands floating in the sky, each one humming with a different feeling – joy, sadness, anger, you name it. As a player, you’d need to fix things by figuring out puzzles that are all about those emotions. Cool, right?
  • Alternatively, consider a city where plants have completely taken over after the world ended. You’d be a little robot botanist, trying to figure out all the new plants that have sprung up. What secrets do they hold?

Gameplay Mechanics

  • What if you were a shadow in a game? You could only move in the dark, so stealth would be your superpower!
  • Now, picture a platformer game, but the whole world moves to the beat of chill lo-fi music. Jump, duck, and slide in time with the rhythm!

Art Style Experiments

  • Let’s get retro! Imagine a game with that bouncy, rubber-hose animation style from the 1930s cartoons. Throw in some grainy film effects for extra vintage charm.
  • Or how about a pixel art detective story set in a dark, rainy city with neon lights flickering everywhere? This is a modern take on classic noir!

Narrative-Driven Concepts

  • Think about a visual novel where you play as a ghost. You get to experience your last day on Earth through the memories of the people you knew. Heavy stuff!
  • What if your choices changed the past instead of the future? That’s the idea behind this RPG. How would you rewrite history?

Whimsical & Cozy Vibes

  • This idea is adorable: you are a raccoon who operates a small café in the forest for all the woodland creatures! Imagine the cozy crafting possibilities!
  • Picture yourself as a cloud, drifting around and changing the weather. You could influence how people feel in different towns. Aww!

Rosebud’s got even more examples on their blog, like a cyberpunk pretzel delivery game called “Robo-stache Pretzels” and a spaceship adventure across endless deserts called “Desert Dunes Explorers.” Maybe those will spark something new!
