Yes, that's right - I was demonstrating why Tronic's 'class method' style call would not work for an instance method - as in the comments...
Code: Select all
# Trog::Door is a class, not a Door!

Aaah - now I see!
Didn't read my own API docs! - the correct method is, of course "
is_open?" not plain old "open?" - D'oh!

No prob -
i knew there must be a typo or...
ruby is 2 new 4 me - especially even w/o gems and some standard libs missing!
Even version conflicts/bugs inside ruby and the 'perfecto'
editor in FS makes it more difficult 4 a beginner...
Keep on doing!
P.S: got an access denied error - damn where is that monster coming from (different schematic btw.)

What are you tying to access that it won't let you?

It was a:
'Dir.mkdir(temp_subfolder_name) unless File.exists?(temp_subfolder_name) # make folder if not exist'
i changed it into this:
if File.directory?(temp_path) #sun mod 20130503
#do nothing
#watch 'temp_path exist', temp_path
else
#watch 'temp_path_dont exists', temp_path
Dir.mkdir(temp_subfolder_name) unless File.exists?(temp_subfolder_name) # make folder if not exist
end
