Hi all,

Playing around more with rrobots.

Method tick in class GoofeyBot is called by module Robot (which is
"included" at the beginning of all 4 of my classes).

Robot provides (among many other things) an object called
radar_heading.  I can print the return value of the object just fine
on line 112 (class GoofeyBot) but not at line 69 (class Radar)
(radar_heading returns null here and the next line, 70, generates:

NoMethodError: undefined method `+' for nil:NilClass
./GoofeyDuck.rb:70:in `target?'


Here's my code:

Thanks for any and all help.
