physX_open ( )

A8 This function in ackphysX.h starts the physics simulation loop, and sets up level_load and ent_remove events for automatically registering and unregistering static objects. Alternatively, you can use your own physics loop and handle all registering / unregistering manually.

Algorithm:

function physX_level_load()
{
  if (level_ent)
    pXent_settype(level_ent,PH_STATIC,PH_POLY);
  for (you = ent_next(NULL); you; you = ent_next(you))
  { 
    if (you.emask&DYNAMIC) continue;  // only register static ents
    if (you.flags&PASSABLE) continue;	
    var type = ent_type(you);
    if (type >= 2 && type <= 5)  // blocks, models, or terrain
      pXent_settype(you,PH_STATIC,PH_POLY);
  }
}

function physX_ent_remove(ENTITY* ent)
{
  if (ent.body) // unregister entity before removal
    pXent_settype(ent,0,0);
}

function physX_open()
{
  physX_load();
  pX_setsteprate(60,8,0);
  pX_setunit(1/40);

  on_exit = physX_destroy;
  on_level_load = physX_level_load;
  on_ent_remove = physX_ent_remove;
 
  while(1) {
    physX_run(time_step/16);
    wait(1);
  }
}
