I've looked the code of planet survivor (AUM37), but I haven't understood some part of the code.
First the cutscene.
Code:
 while (my.x < 3000)
   {
      my.roll += 1.5 * time;
      ent_playsound (my, engine1_wav, 300); 
      my.x += 52 * time;
      vec_set(temp, my.x); 
      vec_sub(temp, camera.x); 
      vec_to_angle(camera.pan, temp); 
      wait (1);
   }

So...
The player roll and move until his x is 3000 whit a speed of 52 units * time
But the camera?

Second
Code:
  while (my.shield > 0)
   {
      camera.tilt += 10 * mouse_force.y * time;
      camera.pan -= 10 * mouse_force.x * time;
      if ((camera.pan > 30) && (camera.pan < 330)) // don't allow the player to blow our cover (if it looks back)
      {
         if (camera.pan < 180) 
         {
             camera.pan = 30;
         }
         else 
         {
             camera.pan = 330;
         }
      }
      if (camera.tilt < -35)
      {
         camera.tilt = -35;
      }
      if (camera.tilt > 25)
      {
         camera.tilt = 25;
      }
      my.pan = camera.pan; 
      my.tilt = camera.tilt;

This code must force the tilt and the pan of the camera right?
I don't know why, but this only work for the tilt Oo

Code:
function destroy_asteroid()
{
    my.x = -30000; 
    wait (1);
    my.event = null;
    ent_create (explo6_pcx, my.pos, explode_me);
    my.passable = on;
    my.invisible = on;
    ent_playsound (my, hit_wav, 1000);
    sleep (2); 
    ent_remove(my); 
}

function move_asteroid
{
    var meteor_angle;
    var meteor_speed;
    my.enable_impact = on;
    my.enable_entity = on;
    my.event = destroy_asteroid;
    my.scale_x = 5 + random(10);
    my.scale_y = my.scale_x;
    my.scale_z = my.scale_x;
    my.skill10 = my.scale_x; // store the scale in skill10 - we will use it to adjust the size of the explosion later
    meteor_angle.x = 3 - random(6); // random pan speed
    meteor_angle.y = 3 - random(6); // random tilt speed
    meteor_angle.z = 3 - random(6); // random roll speed
    meteor_speed.x = (-100 - random(80)) * time;
    meteor_speed.y = 0;
    meteor_speed.z = 0;
     while (my.x > -21000)
    {
       my.pan += meteor_angle.x * time;
       my.tilt += meteor_angle.y * time;
       my.roll += meteor_angle.z * time;
       move_mode = ignore_you + ignore_passable;
       ent_move (nullvector, meteor_speed);
      wait (1);
    }
    ent_remove (my);
}

action asteroid_maker
{
    fog_color = 1;
    var temp_var;
    my.passable = on;
    my.invisible = on;
    while (1)
    {
       temp.x = my.x;
       temp.y = 5000 - random(10000); // -5,000 to 5,000
       temp.z = 1000 - random(2000);
       if (ready_to_play == 0) // game not started yet?
       {
          if ((temp.y > -500) && (temp.y < 500)) // the asteroid is too close to the player during the cut scene?
          {
              temp.y = 500; // then avoid the player until it is able to control the ship
          }
       }
       temp_var = random(1);
       ent_create (asteroid1_mdl, temp, move_asteroid);
       wait (2);
    }
}


I've some problem with this too.
Asteroids collide each other and generate an explosion
Some of this asteroids seems to be not passable, so if I hit it with the rocket these continue moveing.

Thx for all explaination

and sorry for my bad english >_<
