on desktop and on android away physics works perfect few times faster than jiglib, but on iOs situation is opposite, away physics slowing down application for some reason from 60fps to 1-2frs.

we compiling it with air 3.2
is it our mistake or some alchemy bug on iOs?

Hello,

We haven’t done many tests for IOS yet physic wise.
Which device are you using for testing ?

Can you supply me a test which showcasing your issue for Away Physics and jiglibflash ?

Cheers,
Ringo.

Hello, Ringo
thank you for reply

we testing physics on iPhone4s with very simple scene where few boxes falling to the plane
I’ll supply you with source code within 24h

Ok cool, contact me @ringo3d on Skype.

I am interested in ios dev, any joy?

Hi guys! Are there any news for using Awayphysics on iphone? I also have a very low frame rate (0-1) on the iphone. I use air 3.3, Flex 4.6, swf-version 16.

Hello Richard,

No, didn’t find the time yet to test/optimize it (if possible) and the person never did contact me.

If you can supply me simplified example which has this low framerate then I can test it and see if we can optimize it in some way.
I also will be able test it with the upcoming flascc (‘alchemy 2’) branch.

Cheers,
Ringo.

Hello Ringo,

thank you for the reply. I had the time to test a little bit. It seems that the calculation is so slow, that there is no chance to bring my idea to life. I would need min. 14 rigidbodys with self-interaction, which slows the whole down to 0fps. With 3 rigidbodys it has about 15fps until it comes to the collision.
I few things which had little impact at the optimization were the physicsWorld.scaling, the scaling of the used objects and the usage of the box-shape instead of others where possible.
There are projects with bullet physics on IPhone which run smooth, but I don’t know if thats possible with AIR.

I send you the code, maybe there is something I didn’t think of.

It would be great to see AwayPhysics on the IPhone like in the Flashplayer, cause it’s a lot of fun to play with physics.

Cheers

Richard

It works but not that way similar to what I expect.

Thanks.
