| ---# 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. | |
