Does this help any?

Code:

#----------------------------------------------------------------------------
  # * Get line of sight
  #----------------------------------------------------------------------------
  def line_of_sight?(xa, ya, xb, yb)
    dx = (xa - xb).abs
    dy = (ya - yb).abs
    x = xa
    y = ya
    n = 1 + dx + dy
    x_inc = (xb > xa) ? 1 : -1
    y_inc = (yb > ya) ? 1 : -1
    error = dx - dy;
    dx = dx*2 #do this to
    dy = dy*2 #get rid of fractions

    n.downto(0){ |i|
      if !$game_map.passable?(x, y, 0) #$game_map.terrain_tag(x, y) == 5
        return false
      end

      if (error > 0)
        x = x + x_inc
        error = error - dy
      else
        y = y + y_inc
        error = error + dx
      end
    }
    return true
  end
