Porting Half-Life 2 to Web: Memory Management Challenges
Porting a 20-year-old physics-heavy masterpiece to the web isn't actually a graphics problem. It's a memory management war. Most people assume the hurdle is getting the shaders to look right in a browser, but the real fight happens in the heap. WebAssembly is great, but it doesn't just magically handle the kind of aggressive memory allocation these old engines rely on. When you're dealing with a codebase written before modern garbage collection was a standard consideration, you end up with leaks that would make a C++ developer blush. I've spent the last few weeks chasing a memory leak that only appeared when a specific type of physics object collided at a certain angle. It's the kind of tedious, invisible work that makes you wonder why we bother bringing legacy software to the browser at all. The result is a weird tension. You have this incredibly stable, polished game on one side and the volatile, sandboxed environment of a web browser on the other. Ge...
