Building the AI Arena Training Aid: A Vibe Coding Journey
What happens when you combine blockchain gaming, neural networks, and AI-assisted development? One developer’s public journey to solve AI Arena’s training challenges—and what it reveals about the future of rapid prototyping.
The Problem That Needed Solving
If you’ve spent any time in AI Arena—the blockchain-based fighting game where you train AI-powered NFT fighters instead of controlling them directly—you know the training phase is both the most crucial and the most challenging part of the game.
Picture this: You’ve purchased an NFT fighter for several ETH. Its neural network is completely untrained, performing random actions like a newborn learning to walk. Your job? Teach it to become a champion through Imitation Learning, where your fighter watches and copies your gameplay. Get it right, and you climb the global leaderboard earning $NRN tokens. Get it wrong, and your expensive NFT becomes fodder for better-trained opponents.
The problem? Training an AI fighter effectively requires understanding complex concepts like:
- Optimal training intensity configurations
- Balance between offensive and defensive demonstrations
- When to focus on specific positioning scenarios
- How to avoid creating predictable, easily-countered patterns
- Tracking training progress across multiple sessions
Most players approach training by feel, making inconsistent improvements and wondering why their fighters plateau or develop bad habits. The game provides tools, but no systematic framework for effective training strategy.
That’s where the AI Arena Training Aid comes in.
Enter: The Vibe Coding Experiment
Here’s where this story takes an interesting turn. Rather than spending months building this tool the traditional way—designing mockups, writing backend code, configuring databases, deploying infrastructure—I decided to test the limits of modern AI-assisted development.
The approach: Use Lovable’s AI platform to “vibe code” the entire application, building in public and documenting the journey at vibe-build-chronicles.lovable.app.
For those unfamiliar with “vibe coding”—the trend taking over developer communities in 2025—it’s essentially describing what you want to build and letting AI generate, test, and debug the entire application. You provide the vision and requirements; AI handles the implementation details.
The skeptics are right to raise eyebrows. Vibe coding has legitimate risks: technical debt, security vulnerabilities, maintenance nightmares. But for rapid prototyping and MVPs? It’s becoming impossible to ignore the speed advantage.
What the Training Aid Actually Does
The core functionality addresses the systematic training gap that holds players back:
Training Session Planning
Before you start a training session, the tool helps you define clear objectives. Are you teaching your fighter to handle aggressive rushdown opponents? Defensive positioning? Combo execution? Each session gets structured intent rather than random demonstrations.
Configuration Management
AI Arena offers dozens of training parameters—focus areas, intensity sliders, action representation settings. The Training Aid provides preset configurations for common scenarios (teaching footsies, anti-air responses, tech chase follow-ups) and lets you save custom setups that work for your play style.
Progress Tracking
After each session, log what you taught and how your fighter responded. The tool creates a training history showing which lessons stuck and which need reinforcement—something the base game doesn’t provide.
Strategy Repository
A community-sourced collection of effective training approaches. See what’s working for top players, contribute your own discoveries, and avoid reinventing the wheel as you develop your fighter.
Training Schedule Recommendations
Based on your fighter’s current ELO, weight class, and fighting style, get suggested training priorities. Strikers need different focus than Sluggers; climbing from Bronze to Silver requires different preparation than competing in Diamond tier.
The Building in Public Philosophy
Here’s what makes this project unusual: everything is being developed transparently at the chronicle URL. Not just the finished product, but the messy middle:
- The prompts that generated each feature
- The iterations when AI got it wrong the first time
- The debugging sessions fixing edge cases
- The design decisions and their rationale
- The feature requests from the community
- The pivots when original ideas didn’t work
This transparency serves multiple purposes. For other AI Arena players, it’s a window into what’s coming and an opportunity to influence development. For developers curious about vibe coding, it’s a real-world case study showing both the power and limitations of AI-assisted development. For the project itself, building in public creates accountability and momentum.
The Technical Stack (Built in Hours, Not Weeks)
Using Lovable’s platform, the Training Aid leverages:
Frontend: React-based responsive interface that works on desktop and mobile—because you’re often training with a controller while referencing the tool on your phone.
Data Layer: Local storage for personal training logs, with cloud sync for configuration sharing and community strategies.
Integration: Hooks into AI Arena’s metadata where possible (weight class, element, generation) to provide contextual recommendations.
UI/UX: Clean, focused interface that doesn’t overwhelm. Training configuration should take 30 seconds, not 10 minutes of menu diving.
The remarkable part? From concept to working prototype took days instead of months. The AI handled component structure, state management, routing, responsive design, and basic error handling. The human focused on the problems worth solving and the experience worth creating.
Why This Matters Beyond AI Arena
This project represents something larger than a training tool for a single game:
For Blockchain Gaming: It demonstrates that community-built utilities can fill gaps faster than official development teams, especially in the fast-moving web3 gaming space where player needs evolve rapidly.
For AI-Assisted Development: It provides a concrete example of vibe coding applied to a real problem with real users, moving beyond tutorial apps and to-do lists.
For Building in Public: It shows how transparency can be a competitive advantage rather than a vulnerability, attracting collaborators and building trust with users from day one.
For Rapid Prototyping: It proves you don’t need a team, funding, or months of runway to validate whether an idea has product-market fit.
The Challenges (Because Nothing Is Perfect)
Let’s be honest about the obstacles:
Vibe Coding Limitations
AI is excellent at generating standard patterns but struggles with complex business logic. The training recommendation algorithm required significant human refinement because AI kept producing generic advice rather than AI Arena-specific insights.
Blockchain Integration
Connecting to wallet APIs and on-chain data is still harder than it should be. AI can scaffold the structure but often hallucinates method names or uses deprecated Web3 libraries.
Maintenance Concerns
Code generated rapidly needs careful review. Technical debt accumulates fast if you’re not vigilant about refactoring AI-generated components into maintainable patterns.
Community Coordination
Building in public means managing expectations. Players want features yesterday, and being transparent about what’s in progress sometimes creates pressure to deliver before validation.
What’s Next: The Roadmap
The Training Aid is functional but far from complete. Upcoming features include:
Fighter Performance Analytics
Track your fighter’s ELO over time correlated with training sessions. Identify which training approaches actually improve win rates versus which feel productive but don’t translate to results.
Sparring Partner Matching
Connect with other players for controlled training matches rather than risking ranked ELO. Test specific scenarios and counter-strategies in a low-stakes environment.
Meta-Game Insights
As the AI Arena competitive scene evolves, surface trending strategies and counter-play options. If everyone’s running aggressive Striker builds, know that defensive Slugger training becomes higher priority.
Video Training Analysis
Upload footage of your training sessions or battles. The tool analyzes your demonstration quality, identifies gaps (you never showed defensive tech, your combo timing is inconsistent), and suggests focused training.
Training Templates Library
Downloadable training session plans from top players. Load a configuration, run the session, see what world-class players teach their fighters.
The Broader Implications
AI Arena represents the cutting edge of AI-powered blockchain gaming—a space where neural networks aren’t just buzzwords but actual game mechanics. Players are effectively serving as AI trainers, using Imitation Learning to create unique fighting policies.
The Training Aid exists because complex systems create tooling opportunities. Just as World of Warcraft spawned DPS meters, raid planners, and auction house analyzers, AI Arena’s depth demands systematic approaches to training strategy.
But here’s the deeper insight: As AI becomes embedded in more applications and games, the meta-layer of tools to optimize AI interactions becomes increasingly valuable.
We’re not just playing games anymore; we’re coaching machine learning models. We’re not just using software; we’re teaching neural networks how we want them to behave. The players who understand this paradigm shift—who approach AI training systematically rather than intuitively—will dominate competitive scenes.
The Vibe Coding Lesson
This project started as a solution to a personal frustration: wasting hours on ineffective training that didn’t translate to better fighter performance. Using AI-assisted development, what might have been a six-month side project became a functional prototype in days.
The key lessons:
✅ Vibe coding excels at rapid MVP development when you have clear requirements and can articulate what you want.
✅ Building in public creates forcing functions that prevent endless tinkering and encourage shipping.
✅ AI-powered tools reduce the barrier between “I wish this existed” and “I built this.”
✅ Specialized tools for niche communities can have outsized impact because incumbents often ignore small markets.
✅ The future belongs to builders who combine domain expertise with AI-assisted implementation speed.
