Hi!

I'm programing friend npc, who I can make following me.
the problem is, when I got more then one friend, and they try to follow me, they walk into each other.

how can I make them not touch each other and still follow me?

here is the friend code so far:
------------------------------------------------------
action skinnyfriend()
{
my.HEALTH = 100;

var follow_mode = false;
VECTOR temp;
VECTOR skinnyfriend_distance;

while(my.HEALTH > 0)
{
if(player)
{

if(follow_mode == true)
{

vec_set(temp, player.x);
vec_sub(temp, my.x);
vec_to_angle(my.pan, temp);
my.tilt = 0;



if(vec_dist(my.x, player.x) < 340 && vec_dist(my.x, player.x) > 50 && player.HEALTH > 0)
{

skinnyfriend_distance.x = 10 * time_step;
skinnyfriend_distance.y = 0;
skinnyfriend_distance.z = 0;

c_move(my, skinnyfriend_distance, nullvector, NULL);
ent_animate(my, "run", my.skill1, ANM_CYCLE);
my.skill1 += 9 * time_step;
if(my.skill1 > 100) {my.skill1 = 0;}
}

if(vec_dist(my.x, player.x) < 50 || player.HEALTH < 1)
{
ent_animate(my, "control", 1, ANM_CYCLE);
vec_set(temp, player.x);
vec_sub(temp, my.x);
vec_to_angle(my.pan, temp);
my.tilt = 0;
}

if(key_2)
{
follow_mode = false;
}
}

else if(vec_dist(my.x, player.x) < 70 && player.HEALTH > 0)
{
ent_animate(my, "control", 1, ANM_CYCLE);
vec_set(temp, player.x);
vec_sub(temp, my.x);
vec_to_angle(my.pan, temp);
my.tilt = 0;

if(key_1)
{
follow_mode = true;
}
if(key_3)
{
//shut up
}
if(key_4)
{
//run n' hide
}
}



else if(vec_dist(my.x, player.x) < 30 && player.HEALTH > 0)
{
c_move(my,vector(-1 * time_step, 0, 0), nullvector, GLIDE);
}

else if(vec_dist(my.x, player.x) < 150 && player.HEALTH > 0)
{
vec_set(temp, player.x);
vec_sub(temp, my.x);
vec_to_angle(my.pan, temp);
my.tilt = 0;

ent_animate(my, "shout", my.skill4, ANM_CYCLE);
my.skill4 += 9 * time_step;
if(my.skill4 > 100) {my.skill4 = 0;}
}

else
{
ent_animate(my, "idle", my.skill3, ANM_CYCLE);
my.skill3 += 1 * time_step;
if(my.skill3 > 100) {my.skill3 = 0;}
}

}

wait(1);
}
}

Thanks for the help!
