In this case I would define one entity as leader who is the one who follows the path. The other entities should not follow the path but follow one other entity. a-> follows -> b -> follows -> c -> follows -> d -> follows path. If you define a minium distance to the next entity, it is possible to avoid colliding. [EDIT] If the distance between these objects is too large, the following entities don't stay on the path. hope this helps a bit Last edited by slacer; 10/19/15 15:50.

slacer's way is very good.

If you use my find the vec for path node from my old post and the last time we talked about paths , you can

Make leader looks at node, follower A looks at Leader_node-1, follower B looks at Leader_node -2, follower C looks at Leader_Node -3.

Slacer's Way

Code:

action leader ()
{
Leader = my;
 .. .find path , follow path
} 

action follower_a() 
{
 Follower_A =my;
while(x)
{
 if(Leader.on_path == 1)
 {
   if( vec_dist(my,Leader) > 50 )
     { 
       vec_to_ang( to look at LEADER); 
       c_move(....);
      } 
   } 
wait(1);
}

action follower_b() 
{
 Follower_B =my;
while(x)
{
 if(Leader.on_path == 1)
 {
   if( vec_dist(my,Follower_A) > 50 )
     { 
       vec_to_ang( to look at Follower_A);
       c_move(....);
      } 
   } 
wait(1);
}
action follower_c() 
{
 Follower_C =my;
while(x)
{
 if(Leader.on_path == 1)
 {
   if( vec_dist(my,Follower_B) > 50 )
     { 
       vec_to_ang( to look at Follower_B); 
       c_move(....);
      } 
   } 
wait(1);
}

Man I hope this works --- it's the right idea, but may have issue - I can't test it.

Possible issues in the my.NODE_NEXT=path_nextnode(......); of the followers.

Possible need for a while(!ent_glob_leader){wait(1);}

EDIT - one more possible - possible need for
while(ent_glob_leader.NODE_NEXT <2){ wait(1);}
while(ent_glob_follower_a.NODE_NEXT <2){ wait(1);}
while(ent_glob_follower_b.NODE_NEXT <2){ wait(1);}

any ways have fun
