I have a bit of a general problem (I am still new to lite C). Suppose I have code as below; In follower_action, how to make the follower's coordinates always be the same as that of the entity which was passed to add_follower?
action follower_action()
{
while(1)
{
me.x = ?;
me.y = ?;
me.z = ?;
wait(1);
}
}
function add_follower(ENTITY* ent)
{
ENTITY* follower = ent_create(... ,follower_action);
}

Try this:
action follower_action()
{
ENTITY* ent = ptr_for_handle(my.skill10);
while(1)
{
vec_set(my.x,ent.x);
wait(1);
}
}
function add_follower(ENTITY* ent)
{
ENTITY* follower = ent_create(... ,follower_action);
if(ent != NULL)follower.skill10 = handle(ent);
}
EDIT: I never heard about that...

The code exactly as you wrote it does not work for me (it is not following), but if I put ENTITY* ent = ptr_for_handle(my.skill10); within the loop, as below, it does work. I have no clue why is this happening. Any explanation?
action follower_action()
{
while(1)
{
ENTITY* ent = ptr_for_handle(my.skill10);
vec_set(my.x,ent.x);
wait(1);
}
}

Could be because follower action is starting "too" quickly, before my is finished being created. Try this. action follower_action()
{
wait(1);
ENTITY* ent = ptr_for_handle(my.skill10);
while(1)
{
vec_set(my.x,ent.x);
wait(1);
}
}

Try this. Thanks EvilSOB, that works. Now I must know when entity is destroyed to stop setting position of follower. I wrote something like this:
action follower_action()
{
wait(1);
while(1)
{
ENTITY* ent = ptr_for_handle(my.skill10);
if (ent != NULL)
vec_set(my.x,ent.x);
wait(1);
}
}
If new entity appears in the meantime after current one is destroyed, follower jumps on that new entity as if handle has been reassigned to new entity. How can I positively detect that the original entity has been destroyed?

Easy, use this, it what I understand you to be after.
action follower_action()
{
wait(1);
ENTITY* ent = ptr_for_handle(my.skill10);
while(ent)
{
vec_set(my.x,ent.x);
wait(1);
if(ent != ptr_for_handle(my.skill10)) ent = NULL;
}
}
