Looking at doing a simple 2D physics based game for iPad use. Anyone recommend a good engine? I've used box2d in the past, but it has been updated and the docs haven't and I've had some issues getting it working again. I like the look of Fisix but it seems dead on arrival... never got out of alpha - and sitting that way for like 5 years now.
So, what can be used? I can probably target iPad2 for this, so I think performance should be ok. I just can't find a good 2d engine for As3.
The thing is that most out-of-the-box engines won't perform well on iOS, especially on iPads. Box2D e.g. is optimized for CPU rendering and thus you won't come up with more than 10fps on an iPad. I've written my own little engine with basic velocity calculations and stuff and had a tough time optimizing it for GPU renderings. So actually I am on 50fps now with 20-30 objects on stage but I can't imagine that an existing engine can catch up with it. It's very important to understand what you're doing when targeting mobile devices as otherwise your performance will just disappoint.
Btw. the iPad 2's performance isn't much better, I'll come up to 56fps (instead of 51) but actually it's not really noticable (and yet hasn't been in any performance tests I've done so far)
I guess things have moved a long a little in the last few months.
Did you get anywhere with box2d ?
I'm currently looking at box2D or nape.
box2d has more documentation/tutorials etc out there, but nape does look pretty good (in terms of ease of coding and performance).
Can anyone recommend which is best for mobile ? Or is there a better option ?
