physics thread problem

Post  sctm81 on Tue May 12, 2009 3:02 am

I am using a thread like templatePhysicCullingThread( void *_ptr ) in tutorial 6_2 to call the functions

sio2PhysicRender( sio2->_SIO2physic, 1.0f / 60.0f, 1 );
sio2ResourceCull( _SIO2resource, sio2->_SIO2camera );

to simulate the physics of 2 objects. For some reason the simulator runs for 1 second and then gets stuck at an unidentified location. Any clues anyone? Do I need an extra sleep command in the thread?

Are you messing around with the btRigidBody in the main thread? Cuz Bullet is not thread safe... The only operation that you are allowed to do is read the matrix... any other write operation handled by Bullet will result into a segfault.
