Collision with high speed object (ccd)

I create small rigid body object with cylinder collision shape and big box static object with box collision shape. I apply impulse to my small object:

Code:


//direciton - unit vector
//power - value between 60 and 80
obj->applyImpulse(direction*power, btVector3(0,0,0));


With 90% probability it collision with big box and bounce.
With 10% probability my small object move through big box.

My physic render code:

Code:


btSoftRigidDynamicsWorld->stepSimulation( 1.0f / 60.0f, 0 )


I think that i do not enable continuous collision detection (ccd) and call that function for my small object:

Code:


obj->setCcdMotionThreshold( 0.5f );
obj->setCcdSweptSphereRadius( 0.2*0.5f );


but that not help me.

What code i must edit or paste for 100% chance to collision and bounce?

I looked http://www.bulletphysics.com/Bullet/phpBB3/ but not found easy solution, but all wrote that bullet support ccd.
I am confusion

Increase the simulation step to a level that you feel is acceptable...

If i write:

Code:

sio2PhysicRender( sio2->_SIO2physic, 1.0f / 200.0f, 1 );

On device ( and simulator ) game run slowly. I want that player see high object speed.

And if i increase implulse power to 200 i will have same miss effect.

More like:

sio2PhysicRender( sio2->_SIO2physic, 1.0f / 60.0f, 4 or 8 or something between that );

Thanks
That really better. I set _pass = 4 in sio2PhysicRender because with _pass=6 i have slower game speed.
But sometimes this decision miss collision check cylinder shape with triangle shape. I bound my static triangle mesh with ghost static boxes in blender and now i check collision only with bound boxes. That give me good collision detect and bounce.
