看rrobots的一個簡單的例子:
----------------------- code -----------------------
require 'robot'
class NervousDuck
?? include Robot
? def tick events
??? turn_radar 1 if time == 0
??? turn_gun 30 if time < 3
??? accelerate 1
??? turn 2
??? fire 3 unless events['robot_scanned'].empty?
? end
end
----------------------- code -----------------------
這里至少要實現tick方法.
下面是控制robot的一些方法和屬性:
? battlefield_height? #the height of the battlefield
? battlefield_width?? #the width of the battlefield
? energy????????????? #your remaining energy (if this drops below 0 you are dead)
? gun_heading???????? #the heading of your gun, 0 pointing east, 90 pointing
????????????????????? #north, 180 pointing west, 270 pointing south
? gun_heat??????????? #your gun heat, if this is above 0 you can't shoot
? heading???????????? #your robots heading, 0 pointing east, 90 pointing north,
????????????????????? #180 pointing west, 270 pointing south
? size??????????????? #your robots radius, if x <= size you hit the left wall
? radar_heading?????? #the heading of your radar, 0 pointing east,
????????????????????? #90 pointing north, 180 pointing west, 270 pointing south
? time??????????????? #ticks since match start
? speed?????????????? #your speed (-8/8)
? x?????????????????? #your x coordinate, 0...battlefield_width
? y?????????????????? #your y coordinate, 0...battlefield_height
? accelerate(param)?? #accelerate (max speed is 8, max accelerate is 1/-1,
????????????????????? #negativ speed means moving backwards)
? stop??????????????? #accelerates negativ if moving forward (and vice versa),
????????????????????? #may take 8 ticks to stop (and you have to call it every tick)
? fire(power)???????? #fires a bullet in the direction of your gun,
????????????????????? #power is 0.1 - 3, this power will heat your gun
? turn(degrees)?????? #turns the robot (and the gun and the radar),
????????????????????? #max 10 degrees per tick
? turn_gun(degrees)?? #turns the gun (and the radar), max 30 degrees per tick
? turn_radar(degrees) #turns the radar, max 60 degrees per tick
? dead??????????????? #true if you are dead
? say(msg)??????????? #shows msg above the robot on screen
? broadcast(msg)????? #broadcasts msg to all bots (they recieve 'broadcasts'
????????????????????? #events with the msg and rough direction)
