Create 'Coins' at runtime (SpeedBoost)

Hi! I'm already working on a platformer and have good performance on iphone5 and pc (60fps).

on iphone4 it drops down to 30 fps. i have about 300 coins (active obj) in the frame. i always hide them,
if they are outside the screen. this does help a little bit for performance, but MUCH better is to create them at runtime, i think.

(I've deleted just the coins and got a speed boost ;) )

but how would you handle this? if i start a fastloop checking the xpos of the player i think the speedboost is gone.

isnt there some nice way to create the objects just if they are visible? (as long as the player doesnt collect them, of course)


thanks for your suggestions!

ok, hmmm, I've learned again ;)

For everyone expieriencing a similar problem, don't trust in "Inactive if too far from window -> Automatic"

If you need speed, set it to "YES". It boost my game from 30 fps to 60 fps (960x640 res -> 9000x2000 pixel frame)

Yeah, I always set that option to YES for anything I don't need to be monitoring off screen, it makes a huge difference to performance.
