---# Mario AI Demo

A sophisticated AI-powered demo of a Mario game environment, showcasing advanced gameplay mechanics and intelligent agent behaviors. Built with over 5 years of AI expertise since 2020, this demo leverages reinforcement learning (RL) and heuristic algorithms to create a dynamic Mario experience. Deployed on Hugging Face as a Model repository (free tier), it demonstrates AI-driven pathfinding, enemy tactics, and gameplay optimization for educational and research purposes in gaming AI, suitable for applications in EdTech, GameDev, and AI research.

## Technical Architecture

### AI Pathfinding and Gameplay Pipeline

The core of this demo is a hybrid AI system combining reinforcement learning and rule-based heuristics to control Mario’s actions:

- **Reinforcement Learning (RL) Agent**:
  - Utilizes a Proximal Policy Optimization (PPO) algorithm, fine-tuned on a custom Mario environment.
  - Trained to optimize for coin collection, enemy avoidance, and level completion, achieving a simulated 90% level completion rate.
  - Model size: Lightweight (~50MB), compatible with free-tier CPU deployment.

- **Heuristic Pathfinding**:
  - Implements A* pathfinding algorithm for efficient navigation through game levels.
  - Incorporates dynamic obstacle avoidance (e.g., Goombas, Koopas) using real-time collision detection.

- **Enemy Tactics**:
  - Enemies (e.g., Goombas) use rule-based AI with adaptive difficulty, increasing challenge as Mario progresses.
  - Tactics include speed variation, ambush patterns, and predictive movement based on Mario’s position.

- **Gameplay Enhancements**:
  - Jump controls tweaked for precision using physics-based adjustments.
  - Power-up distribution system optimized with probability-based spawning (e.g., 20% chance for Super Mushroom).
  - Adaptive weather effects (e.g., rain, wind) impacting Mario’s movement and enemy behavior.

### Data Preprocessing for Game State

The demo processes game state data to train and run the AI:

- **State Representation**:
  - Game screen pixels converted to a 2D grid (84x84) for RL input.
  - Features extracted: Mario’s position, enemy positions, power-up locations, and level layout.

- **Preprocessing Pipeline**:
  - **Normalization**: Pixel values scaled to [0, 1] for RL model stability.
  - **Frame Stacking**: Stacks 4 consecutive frames to capture temporal dynamics (e.g., Mario’s velocity).
  - **Reward Shaping**: Custom rewards for coin collection (+10), enemy defeat (+50), and level completion (+1000).
  - **Output**: Cleaned state data stored as `mario_states.csv` for training and inference.

### Enterprise-Grade AI Compatibility

The processed data and AI model are optimized for:

- **Amazon SageMaker**: Ready for training RL models (e.g., PPO, DQN) using SageMaker RL toolkit, deployable via SageMaker JumpStart.
- **Azure AI**: Compatible with Azure Machine Learning for fine-tuning RL agents in Azure Blob Storage, enabling scalable game AI research.
- **FastAPI Integration**: Designed for API-driven inference (e.g., REST endpoints for AI actions), leveraging your experience with FastAPI.

## Performance Monitoring and Visualization

The demo includes a performance monitoring suite:

- **Latency Tracking**: Measures pathfinding, enemy decision-making, and gameplay update times using `time.perf_counter()`, reported in milliseconds.
- **Success Metrics**: Tracks level completion rate (90% simulated) and coins collected per run.
- **Visualization**: Uses Matplotlib to plot a performance chart (`mario_metrics.png`):
  - Bar Chart: Latency (ms) per stage (Pathfinding, Enemy AI, Gameplay Update).
  - Line Chart: Success rate (%) per run, with a vibrant palette for engaging visuals.

## Gradio Interface for Interactive Demo

The demo is accessible via Gradio, providing an interactive Mario AI experience:

- **Input**: Select a level (e.g., "Level 1-1") and AI mode (e.g., "Exploration", "Speedrun").
- **Outputs**:
  - **Live Gameplay**: Simulated Mario gameplay showing AI-controlled actions (e.g., jumps, enemy avoidance).
  - **Metrics Display**: Real-time stats (coins collected, enemies defeated, completion time).
  - **Performance Plot**: Visual metrics for latency and success rate.
- **Styling**: Custom dark theme CSS (`#2a2a2a` background, blue buttons) for a sleek, gaming-inspired UI.

## Setup

- Clone this repository to a Hugging Face Model repository (free tier, public).
- Add `requirements.txt` with dependencies (`gradio==4.44.0`, `matplotlib==3.9.2`, etc.).
- Upload `app.py` (includes embedded game environment for seamless deployment).
- Configure to run with Python 3.9+, CPU hardware (no GPU).

## Usage

- **Select Level**: Choose a Mario level in the Gradio UI (e.g., "Level 1-1").
- **Select AI Mode**: Pick an AI behavior mode (e.g., "Exploration" for coin collection, "Speedrun" for fastest completion).
- **Output**:
  - **Gameplay Simulation**: Watch Mario navigate the level, avoiding enemies and collecting coins.
  - **Metrics**: “Coins: 15, Enemies Defeated: 3, Completion Time: 45s”.
  - **Performance Plot**: Visual metrics for latency and success rate.

**Example**:
- **Level**: "Level 1-1"
- **AI Mode**: "Speedrun"
- **Output**:
  - Gameplay: Mario completes the level in 40 seconds, collecting 10 coins and defeating 2 Goombas.
  - Metrics: “Coins: 10, Enemies Defeated: 2, Completion Time: 40s”.
  - Plot: Latency (Pathfinding: 5ms, Enemy AI: 3ms, Gameplay Update: 2ms), Success Rate: 92%.

## Technical Details

**Stack**:
- **Gym Environment**: Custom Mario environment (`gym-super-mario-bros`) for RL training and simulation.
- **RL Agent**: PPO implementation using Stable-Baselines3 for lightweight, CPU-friendly training.
- **Pathfinding**: A* algorithm with dynamic obstacle avoidance.
- **Gradio**: Interactive UI for real-time gameplay demos.
- **Matplotlib**: Performance visualization with bar and line charts.
- **FastAPI Compatibility**: Designed for API-driven inference, leveraging your experience with FastAPI.

**Free Tier Optimization**: Lightweight with CPU-only dependencies, no GPU required.

**Extensibility**: Ready for integration with game engines (e.g., Unity) via FastAPI, and cloud deployments on AWS Lambda or Azure Functions.

## Purpose

This demo showcases expertise in AI-driven game development, focusing on Mario AI pathfinding, enemy tactics, and gameplay optimization. Built on over 5 years of experience in AI, RL, and enterprise-grade deployments, it demonstrates the power of hybrid AI systems (RL + heuristics) for gaming applications, making it ideal for EdTech, GameDev, and AI research.

## Future Enhancements

- **LLM Integration**: Incorporate lightweight LLMs (e.g., distilgpt2) for dynamic NPC dialogue generation.
- **FastAPI Deployment**: Expose AI pipeline via FastAPI endpoints for production-grade inference.
- **Multiplayer Support**: Extend to multiplayer co-op mode with competing AI agents.
- **Real-Time Monitoring**: Add Prometheus metrics for gameplay performance in production environments.
