falling though world on device

i have created a world and imported it into the tutorial 09 code base.

everything worked great on the simulator, but when i installed the app onto a device all my rigid/dynamic bodies fall though the world.

does any one have any ideas what could potentially cause this behaviour?

-spob

ok i did do a search for similar posts and nothing came up. the searched for my own post and found loads :S

going to work through some of the other suggestions i found

ok

replacing
sio2PhysicRender( sio2->_SIO2physic, sio2->_SIO2window->d_time, 2 );

with
sio2PhysicRender( sio2->_SIO2physic, 1.0f / 30.0f, 2 );

worked but the app does not run at anywhere near the frame rate i was hoping

Check tutorial06_2 and see if you can use multi-thread with the physic?

ok i have finally managed to get a seperate physics thread sorted and things have improved but for a relatively simplistic world far from ideal

rendering: 14 fps
physics: 10 fps

Do not compile with thumb ON

it wasn't on

Dude profile cuz me I get more than 20k of textured polygon per FOV where all objects are physic objects and I get 30+ fps on my iPod Touch 2nd gen...

yeah its obvious there is something wrong with my app, cause i have seen more complex worlds drawn at faster frame rates using this engine. hmm now to find out what's wrong ... i'll post here again if i work anything out

just use shark dude, you'll see it right away...

I don't mean to be a newb. But, afterall I am a newb.. So, what's Shark?
