You can not pass arguments in that way But YOU is always pass as the creator to the created action.

me-> create
created -> parent always is YOU in first run



Code:
//main body action
action body_action()
{
   //msc codes here
   code...

   //create child entity
   ent_create(part1, pos_parentoffset, child_action); //point me as parent entity

   //rest of the child entity code
   code...
}

//child body action
action child_action()
{
   //msc codes here
   code...
   ENTITY* parent_ENT = you;

   while(1)
   {
       //parent_ent pointing to main body
       vec_set(my.x, parent_ent.x);
       wait(1);
   }
}
