You could post in the gamestudio forums and describe the problem there. If you include the corresponding code in your post someone may be able to help you.

maybe this will help. I'm using:
vec_set (temp, pOne.x);
vec_sub (temp, my.x);
vec_to_angle(my.pan, temp);
to have the entities face player one, and am just using a c_move command to have them move forwards so they "chase" the player. If I only have one enemy there's no problems but when I have two, because they are both facing the player, they get stuck on each other during movement.

But the problem isn't with my code, Then you're screwed anyways because you can't change a thing, right? it's just that in G8 when you're using c_move commands and two non passable entities collide, 1 stops moving. Of course one stops moving because otherwise it would end up inside the other one. Btw. there is always exactly one entity moving. You cannot move two objects at the same time. Have you set the glide flag? What part of my code would I need to show? The relevant one ...

1. Yes I have told them to glide 2. I don't know which part is exactly relevant since my question is about how the collision engine works so here is the entire action that the enemies run:
action enemy()
{
c_setminmax(me);
my.emask |= (ENABLE_IMPACT);
my.event = hit_enemy;
my.health = 20;
my.damage = 0; //1 = took damage (invinci timer)
var temp;
while (my.health >= 1)
{
vec_set (temp, pOne.x);
vec_sub (temp, my.x);
vec_to_angle(my.pan, temp);
c_move(me, vector(3*time_step,0,0), nullvector, IGNORE_PASSABLE | GLIDE);
// DEBUG_VAR(my.health, my.y);
if (my.damage == 1)
{
set (my, PASSABLE);
wait(30);
reset(my, PASSABLE);
my.damage = 0;
}
wait(1);
}
ent_remove(me);
}

U should read about "narrow" and "fat", "obstacle avoidence" and "pathfinding". Did u thought a 3d engine handles "correct" movement of models by itself ? If so, no, they wont. ^^ Take a look at Superku's pathfinding.c included in the goodies.zip, if its up to easy non-cost pathfinding. Edit: Ull find a simple and good oa at bottom of this post: http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=428514
