After quite a bit of tweaking I'm also ready to release my aptly named 
HuntingDuck. It will try to move closer to it's prey (while shooting it 
ofcourse).

It seems to be about even with BotOne, but I as its creator might be 
overproud :)

class HuntingDuck
   include Robot
  def initialize bf
    super(bf)
    @time_since=10
    @direction=1
  end
  def rel_direction(from,to)
    rel = to -from
    if rel > 180
      rel = -360 + rel
    end
    if rel < -180
      rel = 360+rel
    end
    return rel
  end
  def rel_gun_heading
    rel_direction(heading, gun_heading)
  end
  def tick events
    accelerate 1
    @direction = -@direction if Kernel.rand < 0.02
    if !events['got_hit'].empty?
      fire 2
      turn -10*@direction
    end
    if !events['robot_scanned'].empty?
      fire 3
      @time_since=0
    else
      if @time_since < 15
        if Kernel.rand < 0.5 && rel_gun_heading < 30
          turn_gun 6
        elsif rel_gun_heading > -30
          turn_gun -6
        else
          turn_gun 6
        end
        fire 0.5
      elsif @time_since < 100
        turn 10*@direction
      else
        turn 5
      end
    end
    @time_since += 1
  end
end
