OK, so as I realized, in "physics" forum, no one was able to answer me.
That the main reason for that I've decided to ask my questions here.
I'm trying to make simple 2D movement, with BOX hull shape for player.
I need to move character only in X coordinates, all other coordinated should be locked.
I need physic object to be able to turn only in TILT, all other angles should be locked.
I want character to react for all forces and gravity as well, not only movement forces by keys.
Here you can download demo of what I've tried to do:

pXent_setccdskeleton(my,vector(0,0,0),1);
while(1)
{
temp.x = 10 * (key_d - key_a) * time_step;
temp.y = 10 * (key_w - key_s) * time_step;
temp.z = 10 * (key_q - key_e) * time_step;
pXent_moveglobal(my,temp,nullvector);
//pXent_movechar(my,temp,nullvector,0);
set_camera();
wait(1);
}
}

function main()

fps_max = 60;
physX_open(); // load physX
level_load(test_wmb); // load level
wait(3); // wait for 3 frames
pX_setccd(1); // activate CCD
// make nice 2D physics
pXent_setbodyflagall(NX_BF_FROZEN_POS_Y|NX_BF_FROZEN_PAN|NX_BF_FROZEN_ROLL,1);
pX_setgravity(vector(0,0,-9.81)); // apply earth gravity
}

So, my questions are:
* how to lock all physic objects in Y, Z, PAN, ROLL (pXent_setbodyflagall doesn't help)?
* how to make PH_CHAR object to react on other forces (for example, gravity and explosions)?
* how to make character collide with other RIGID bodies properly (so they don't pass throw each other, CCD doesn't help)?
