Object limits in a single frame?

[Paul_Boland]

Hi Folks.

Working on a new iOS game for iPad and I have a LOT of items flying around the screen which based on user actions can elevate very high! Now, I can limit these objects but I'd rather not because it looks good the way it is. So I was just wondering what's the object limit for a single frame on an iPad? I know I can change the MMF frame limit from 500 to whatever I want it to be, but how high can I go before an iPad will start to kick up about it?

Depends on your objects of course. You just have to try it. I got one game that is kinda stuck after 100 objects (i try to have 45-50 fps). Another, smaller game has 600 and up objects. So what i know it´s more a try around thing.

Thanks for the feedback. Not yet in a position to do testing on the iPad. Nice to know you had a game with upwards of 600 objects, mine could potentially head into that realm.

It depends on how you construct your frame. I believe the object limit is 20,000 per frame but you'd need to bump the objects up on the frame from 500. Also instances versus unique objects makes a difference. You also need to consider that object out of frame are far far less expensive than in frame. Test on real devices low and high end. USe optimizations around active image sizes 128x128, 256x256 etc. Disable fine detection where possible.

weirdly, on my game (set at 500) i had issues after a while and the active objects failed to get created. I don't know why because i destroyed anything too far from the frame but in anycase changing it to 20,000 fixed it (i doubt anyone playing it would get anywhere near this).
