So here is my creation. It tries to get close to the enemies, while shooting at it. It slaughters NervousDuck, but SittingDuck is its nemesis.
require 'robot'
class HuntingDuck
include Robot
def initialize bf
super(bf)
@time_since=10
@direction=1
@rob_distance=200
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
@rob_distance=events['robot_scanned'][0][0] unless events['robot_scanned'].empty?
if @rob_distance > 800
#make small turret adjustments when distance to enemy is great
turret_turn=3
else
turret_turn=6
end
#turn clockwise or counter clockwise?
@direction = -@direction if Kernel.rand < 0.02
if !events['got_hit'].empty?
#if we got hit we'd better shoot back and try to turn away
fire 2
turn -10*@direction
end
if !events['robot_scanned'].empty?
fire 3
@time_since=0
else
if @time_since < 15
#spotted the enemy, moving closer
#while moving the turret to spot him again
if Kernel.rand < 0.5 && rel_gun_heading < 30
turn_gun turret_turn
elsif rel_gun_heading > -30
turn_gun -turret_turn
else
turn_gun turret_turn
end
fire 0.5
elsif @time_since < 100
#try to spot the enemy
turn 10*@direction
else
#if we got stuck this should get us out
turn 5
end
end
@time_since += 1
end
end
