API

class template

class MyThank < Tank
 def tick(time)       # called when state==nill
    ..use thank api..
 end
 def tick_foo(time)   # called when state==foo
    ....use thank api.. 
 end
end
MyThank  # !!! Indispensable !!!

api

direction are in degree (0..360), positions are in pixel,speed in pixel/tick

@cdir   cannon direction
@cradar radar direction
@a      thank move direction
x,y     thank position
@v      thank speed

turn_radar(delta_direction)  # change radar direction
turn_cannon(delta_direction) # change cannon direction

pivot_by(delta_direction)    # change moving, direction dont'move cannon & radar direction
turn(delta_direction)        # change moving direction with cannon and radar direction
turn_to(direction)           # force current move direction
mindist?                     # true if game border is reach
move                         # apply speed to thank position/direction

fire_good?                   # true if there are (other familly) thank in radar direction
count_bullet                 # number of active bullet (bullet fired by thank and not yet dead)
fire                         # fire a bullet, done if count_bullet() is less than 6

accelerate(dv)
tir(condition, state: cible) { action } # move to state name if condition is true
                                      tick_<@state> will be call next tick
