Particle Effects on iPhone

by Joao Caxaria · in iTorque 2D · 12/09/2008 (5:03 am) · 5 replies

Hi Guys,

I just tried a small sample I did in the iPhone and everything worked perfectly except my particle effect. On the iTGB it shows and behaves as expected but on the device (and the simulator) it just doesn't show anything.

Did anyone encountered this before?

Thanks!

Sounds like it could be a physics issue. Have you checked this thread yet?
TGB 1.7.4 to iTGB Physics.

One iPhone optimizations that particle effects don't draw when they are off-screen. More specifically, when their world limit boundary is too far away from the camera. Try setting a larger world limit.

Before I delve into using particle effects, can someone tell me what their experience is when it comes to realtime playback on the iPhone? Do you have to tone down the effect dramatically, or limit the number of concurrent effects?

depends on how much you overdid it before.
Depending on it you have to drastically reduce it.

Optimally, you don't have many realtime particle effects but well done animated textures. They are less heavy and potentially give you a better quality too if the effect was created in a professional software for that purpose..

Are you saying prerender some effects like in particleIllusion, then use it as an animated image? Doesn't that take up a lot of memory? It's funny how you end up on the other side of the coin - going from losing FPS to losing memory very quickly!
