It looks like there is a an entity problem. I commented the flash part, just to see if the lightnings without flashes would work, and I'm getting error about the sound now... every time it's about an empty pointer... I think it has something to do with:

Code:

        pos_flag = 0;
        counter = 1; 
        you = ent_next(NULL); //get first entity
        while(you != 0 && pos_flag == 0)
         {
           if(you.skill1 == 1 && counter == pos_pick)
            {
              vec_set(line_start.x, you.x);
              pos_flag = 1;
              cloud = you;
            }
           if(you.skill1 == 1 && counter != pos_pick)
            {
              not_cloud = you;
            }
          counter += 1;
          you = ent_next(YOU); //get next entity
        }


It's not finding any entities?

Yeah! IE sucks, use Mozilla...
