DOOM on Google Sheets

This project runs the classic DOOM game inside a Google Sheets document using Google Apps Script and JavaScript. The game is rendered frame-by-frame by updating the background colors of spreadsheet cells.

Features

• Runs DOOM inside Google Sheets.
• Captures frames from the game and renders them as colored spreadsheet cells.
• Updates only changed cells to optimize performance.
• Uses js-dos to emulate the DOS version of DOOM.

How It Works

1. JavaScript Rendering: The HTML file loads DOOM using js-dos and captures frames at a reduced resolution (120x80).
2. Frame Processing: The script detects changed pixels and queues updates.
3. Google Sheets Updates: The Code.gs script updates the spreadsheet with new colors.

Setup Instructions

1. Open a new Google Sheets document.
2. Go to Extensions > Apps Script.
3. Replace Code.gs with the provided script.
4. Add a new file named Index.html and paste the provided HTML code.
5. Save and refresh the spreadsheet.
6. Click DOOM > Launch DOOM in the Google Sheets menu.
7. Adjust the sheet grid to 120 columns × 80 rows.

Known Issues

• Performance is very slow: Updating the sheet cell-by-cell is inefficient.
• Manual Grid Setup: The user must set the correct spreadsheet size manually.
• Limited Colors: Google Sheets does not support true color rendering.

Try It Yourself

Instead of setting it up manually, you can try a pre-configured version here: DOOM on Google Sheets (Live)
