Anime RNG

🌀 Inspiration

I’ve always loved anime and RNG-based games like Destiny and other RPGs that capture the excitement of getting something rare. I wanted to bring that same thrill into Horizon Worlds by creating a simple, accessible experience that anyone can enjoy, but one that also fuels the collector’s drive to get every single card.

⚡ What it does

Anime RNG lets players roll for cards and build their own collection of powerful anime-inspired characters. Players can auto-roll to keep earning while away, view their full collection, and buy booster packs using in-game dust. They can also purchase temporary XP, dust, and luck boosts or unlock a permanent luck boost through an IWP for higher chances at rare cards.

Players can battle their cards in a rock-paper-scissors-style system to earn rewards and complete daily, weekly, and monthly quests to keep progressing and collecting new cards.

🧩 How we built it

I built Anime RNG using Horizon’s built-in scripting AI to help bring my ideas to life. The process involved creating complex PPV systems, designing interactive UI elements, and fine-tuning the overall player experience with the AI’s guidance.

I used Meta AI to generate the anime cards, Horizon’s public asset library for the world’s environment, and Horizon’s AI tools for sound design, model generation, and the skybox. Every element was refined to make the world feel polished, dynamic, and full of personality.

⚙️ Challenges we ran into

The biggest challenge was making sure every system worked together in perfect sync — from PPVs to UI elements and gameplay logic. I also had to manage time constraints while dealing with random bugs and glitches that appeared during testing. Another major challenge was optimizing the UI and overall performance to make sure players could enjoy the game smoothly without lag.

🏆 Accomplishments that we're proud of

I’m really proud of how Anime RNG turned out. It’s such a great feeling when players pull a legendary card — that excitement was exactly what I wanted to capture. I put a lot of effort into making the UI look clean and engaging, including a live feed that shows rare card pulls in real time.

The battle system was another accomplishment I’m proud of. I had to completely overhaul it halfway through development because the original UI setup couldn’t handle the responsiveness I wanted. Despite that, I made it work, and it turned into one of the most fun parts of the game. I’m also proud that Anime RNG feels truly unique — I haven’t seen another game like it in Horizon Worlds.

📚 What we learned

One of the biggest lessons I learned was the importance of debugging. Adding console logs became my best friend for tracking down where things were breaking. I also learned how helpful helper scripts, utils, and constants can be for keeping everything organized and efficient.

Beyond scripting, I improved at designing player tutorials and balancing daily, weekly, and monthly rewards to keep players engaged. I also gained a much deeper understanding of UI design and already have ideas for future updates once the contest deadline is over.

🚀 What’s next for Anime RNG

There’s a lot planned for the future of Anime RNG. I’m working on adding new cards, a PvP battle system, and a more optimized UI that combines blank UI buttons with mesh visuals for smoother performance.

I also plan to introduce a “Build a Team” system where players can create their own lineup of cards, and a feature that lets your favorite card follow your character in the world to show it off. Alongside that, I want to completely rehaul the battle system and make Anime RNG fully multiplayer-integrated, bringing the competitive and social aspects of Horizon Worlds to the next level.
