Does anyone have any sample code for physX car movement that doesn't use wheels? When I use this code the boat moves in global X direction not relative to the boats pan orientation. How do I make my nullvector variable the boat's new orientation?

Code:
while(1)
{
	if (key_cuu == 1)
	{
	pXent_addforcelocal(my, vector(1000,0,0), nullvector);
	}
	
	if (key_cul == 1)
	{
	pXent_addtorquelocal(my, vector(0,0,1000));
	}
		
	if (key_cur == 1)
	{
	pXent_addtorquelocal(my, vector(0,0,-1000));
	}
	wait(1);
}
