1. What Inspired Running Pong in Multiple Browser Tabs?
The inspiration came from a project called Flappy Favi, where a version of Flappy Bird ran in a favicon, the small icon displayed in a browser tab. This innovative use of favicons sparked the idea of expanding the concept to a larger scale by drawing an image across multiple tabs to create a more visible and engaging experience.
This concept addresses the limitation of tiny favicons, which can make it difficult to discern details. By utilizing multiple tabs, the display area is significantly increased, allowing for more complex and visible graphics.
2. What Were the Key Challenges in Creating Multi-Tab Pong?
Creating Pong across multiple browser tabs presented several technical challenges:
- Creating a Grid of Tabs: How to automatically generate a precise grid of tabs to serve as individual pixels for the game display.
- Updating Backgrounded Tabs: Ensuring that all tabs, including those not in focus, update their favicons in real-time to maintain the animation.
- Coordinating Tabs: Establishing communication between tabs to synchronize the game’s visuals and ensure smooth movement of elements like the ball and paddles.
Overcoming these hurdles required innovative solutions to manage tab behavior and inter-tab communication effectively.
3. How Was a Grid of Tabs Created Programmatically?
Creating a grid of tabs manually would be impractical, so AppleScript, a scripting language for macOS, was used to automate the process. AppleScript allowed the developer to:
- Open multiple Chrome windows.
- Create a specified number of tabs in each window.
- Position the windows precisely to stack on top of each other, forming a grid.
The script ensured that each tab loaded with the correct parameters, such as window and tab index, to identify its position within the grid. This automated setup was crucial for managing the large number of tabs required for the project.
4. How Were Favicons Updated Quickly and Efficiently?
Updating favicons rapidly is essential for creating smooth animations. Initially, the browser’s default behavior of checking for favicon updates was too slow, especially for backgrounded tabs. To solve this:
- Web Workers: Web Workers were used to run the favicon update process in a separate thread, bypassing the throttling imposed on backgrounded tabs.
- Timer in Web Worker: A timer within the Web Worker triggered updates and sent messages back to the main document to change the favicon.
This approach ensured that favicons updated approximately four times a second, fast enough to create a fluid animation.
5. How Did the Tabs Communicate and Synchronize?
To coordinate the display across all tabs, a communication channel was needed. The following methods were explored and implemented:
- Query Parameters: Each tab received its window and tab index via URL query parameters, allowing it to know its coordinates within the grid.
- Broadcast Channels: Broadcast Channels were used to distribute information across different tabs on the same domain, enabling one-to-many communication.
- Registration Process: Backgrounded tabs sent registration messages to the main tab, which then acknowledged each tab to ensure synchronization before starting the animation.
These methods allowed the main tab to control and synchronize the visuals across all backgrounded tabs.
6. Why Were Websockets Abandoned for Tab Communication?
Websockets were initially considered for tab communication, but they presented two key issues:
