Poké-Battle

Poké-Battle

This is a Pokemon game built with FastAPI and Python, leveraging Anthropic's Claude AI for creative battle descriptions, attack recommendations, and generating unique personalities for caught Pokemon.

Tech Stack

• Backend: FastAPI, Uvicorn (ASGI server)
• AI Integration: Anthropic's Claude API, custom AI server (ai_server.py) and client (ai_client.py)
• External API: PokeAPI
• Frontend: HTML, CSS, JavaScript (served by FastAPI)
• Dependencies: python-dotenv, httpx, websockets, Jinja2

Setup Instructions

1. Clone the repository:

   git clone <repository_url>
   cd <repository_directory>
   

2. Create a virtual environment:

   python -m venv .venv
   

3. Activate the virtual environment:

   • On Windows:

     .venv\Scripts\activate
     

   • On macOS and Linux:

     source .venv/bin/activate
     

4. Install dependencies:

   pip install -r requirements.txt
   

5. Set up your Anthropic API Key:

   • Create a file named .env in the root directory.
   • Add your Anthropic API key in the following format:

     ANTHROPIC_API_KEY=your_api_key_here
     

   Note: For security, it's recommended to manage API keys using environment variables provided by your hosting environment rather than storing them in a .env file, especially in production.

6. Run the AI Server: Open your terminal in the project root and run:

   uvicorn ai_server:app --reload --port 8000
   

7. Run the Main Game Server: Open a new terminal in the project root (and activate the virtual environment if necessary) and run:

   uvicorn server:app --reload --port 8080
   

8. Open the game in your browser: Go to http://localhost:8080
