Intermittent freezing after running for ~10 minutes #79

Open chadams77 opened 8 years ago

chadams77 commented 8 years ago

The page freezes for a small amount of time every 3s or so after running for roughly 10 minutes. I've looked over my code, and I seem to be deallocating all the vectors I create, although I do create and destroy a lot of b2Vec2 objects every frame. Tried in incognito as well, doesn't appear to be a plugin. Just using box2d-js and jquery. Perhaps there's an issue involving keys to internal memory allocations not being destroyed along with the objects? I'm running in the latest version of Chrome on Windows 10.

I ran a short profile during one of the freezes, Array.destroy is a function I added to the array prototype which is shorthand for "call Box2D.destroy on all elements in this array"

Note that the number of objects being created & destroyed per frame doesn't change during the ~10 minutes before the freezing.
