The collision detection works quite nice with slow down kept to a minimum. (I’m currently testing with around 100 sprites on screen). The [...]
This morning I put together the death animation handling for my sprite system. It was something of a no-brainer in that it’s just a couple of flags (isDying, isAlive) and the system just looks to a different set of resources for the death animation frames. But something struck me about the beauty of handling everything [...]
I’m not one for performing calculated tests across different machines but I thought it might be useful to share a few performance observations with my JS sprite library.
The laptop that I do most of my development on has an Intel Centrino Duo sticker on it. I guess that means it’s at least 2 years or [...]

Currently I have a base sprite class that takes a lot of [...]
