Code for rune spawns:

Iterator<Entity> runes = ec.getAllByDtName("DT_DOTA_Item_Rune");
while (runes.hasNext()){
  Entity e = runes.next();
  Integer handle = e.getHandle();
  if (!seenEntities.contains(handle)){
    System.err.format("rune: time:%s,x:%s,y:%s,type:%s\n", time, e.getProperty("m_iRuneType"), e.getProperty("m_cellX"), e.getProperty("m_cellY"));
    seenEntities.add(handle);
  }
}
