Rotations very slow

[virtualrom]

Hi,
I try to rotate an active object by changing the angle, in mmf2 and Flash it runs great, in IOS it turns very slow.
What can be the problem?

Slow in game or slow in the emulator?

I'm rotating on a 3g and it was fine, so need a bit more information please

size of image/animation frames etc.

I say its either the size of the objects or the visual characteristics of an active object, such as alpha channels.

I think its important to keep in mind that too many alpha channels may cause minor slowdowns (That's something I experienced with VTA..). I suggest you keep to a minimum as possible or you can try the color reduction with the objects and see how it works.

It's running slow in simulator, it's the only object that rotates for a short time in the game.
The object is about 64x40 pixels, so not that big, don't remember exactly as I am not at home now.

The simulator in xcode might not be the best test environment.
Nothing beat actually getting my creation on to the device to really see if it was running correctly or not.

Perhaps its better now but this was with older versions of xcode.

Tested now on iPhone4, same speed as in simulator.
The object size is 64x85 pixels.

Don't know where to look now.

Maybe upload an MFA example so people can see what your doing?

Make sure you have the test mode set to release and not debug mode!

The file is much too big to upload, but I tried around and found out the following:
The more static images there are, the slower the rotation gets.
So I deleted almost all of the images and then it's ok.

Same problem if I use actives or backdrops, jpg or png.

Could just be overloading iOS

In the help there are some tips about optimizing your creations the devices do have a limited amount of CPU power and memory so you have to be concerned about your game design.
