MCP Game Image System
This document explains how the image display system works in the MCP Game.
Overview
The system displays existing images from the server/openai-server/public/image directory on the TV in the virtual house. Instead of generating new images, which was causing 500 Internal Server errors, the system now checks for existing images in the specified directory.
How It Works
- The TV in the virtual house displays images that exist in the
server/openai-server/public/imagedirectory. - The system checks for new images every 10 seconds.
- When a user requests a new image through the TV remote interface, the system selects a random image from the directory.
Adding New Images
To add new images to the TV:
- Place image files (jpg, jpeg, png, gif, webp) in the
server/openai-server/public/imagedirectory. - The system will automatically detect and display them.
- Files should be a reasonable size for web display (recommended: 800x450 pixels).
Usage
- Approach the TV in the virtual house.
- Press Enter to access the TV remote control interface.
- Type any command related to displaying images.
- The system will select and display an image from the available ones in the directory.
Troubleshooting
- If no images are displayed, check if the
server/openai-server/public/imagedirectory exists and contains image files. - Make sure the server is running on the correct port (default: 3002).
- Check the browser console for any error messages related to image loading.
Technical Details
- The system no longer attempts to generate images directly, avoiding the 500 Internal Server errors.
- Images are selected randomly from the directory when requested.
- The system provides appropriate feedback when no images are available.
Connecting to MCP Backend Server
The MCPGame can connect to an external MCP Backend Server to enable advanced AI functionality for the terminal and TV interactions.
Configuration
- Open the
main.jsfile and locate the configuration section at the top:
// --- Configuration ---
const MCP_BACKEND_URL = 'http://localhost:3001'; // MCP Terminal backend connection
const IMAGE_SERVER_URL = 'http://localhost:3002'; // Image server connection
- Update the
MCP_BACKEND_URLto point to your MCP Backend Server:- For local development:
http://localhost:PORT(replace PORT with your backend port) - For production: Use the full URL to your deployed backend server
- For local development:
Required API Endpoints
Your MCP Backend Server should implement these endpoints:
GET /api/status- Returns the status of the MCP systemPOST /api/query- Accepts user queries and returns AI responses
Response Format
The query endpoint should return JSON in this format:
{
"response": "Text to display in the terminal",
"spokenResponse": "Optional text for voice synthesis"
}
Testing the Connection
- Start your MCP Backend Server
- Start the MCPGame server (
node server.js) - Open the game in a browser
- Interact with the computer terminal in the virtual house
- The game will connect to your MCP Backend Server when you use the terminal
