Hi all, I've been working with my own "engine" for ToW and Invadazoid (if you can call it an engine), but I've maxed out its capabilities and its taking me too long to add the features that other 2D engines already have. I've been looking at available 2D engines on the market and am having an awful time trying to decide, so I thought I'd voice my thoughts and get some feedback. I need something that is easy to learn, is quick and has alpha support. 1. Popcap framework - Its free, its well tested, it seems pretty fast (and smooth) and has alpha support, but after playing around with the demos it wasn't as easy to learn as I would have hoped and seemed to have the same jitter that Invadazoid originally had even when I had turned the movement to the smooth option (with quite a few sprites on the screen of course). 2. PTK - I like the API, but I always thought it required OpenGL which was a turn off for me because I think the casual market is not as willing to go out and find drivers and such, not to mention my own computer has problems with almost every OpenGL game I've tried. I just recently found out on another thread here though that PTK supports DirectX only as well... can anyone verify this, does it still support alpha values under DX? 3. Torque Game Builder - This seems really cool, easy to use and I would get it in a second except that I believe its OpenGL only, which could be a problem for the same reasons as above. So what does everyone think? These are the only ones I spent any time looking at, but if anyone has any better suggests feel free to add them.
