Sharing variables between functions

kybasche

Hey all.

One day, I'll get good enough at this to offer help instead of only asking question.
But for now:

I would like to be able to use variables from one function inside a different function. Please forgive my poor scripting - but as an example...

module Plugin

unless file_loaded?("program.rb")
mymenu = UI.menu('Plugins').add_submenu('test')
mymenu.add_item('Test Program') {self.Box}
mymenu.add_item('Test Program 2') {self.Circle}
file_loaded("program.rb")
end #unless

def self.Box()
a = 5
b = 6
c = a * b
end #Box

def self.Circle()
d = 12
e = d * a ##this won't work of course, because (a) is not defined within this function... how do you pull the value of (a) from Box?
end #failCircle

end #module

Thanks much!

Hi Derek,

Make variable a a class instance variable e.g.@a.

def self.Box()
@a = 5
b = 6
c = @a * b
end #Box

def self.Circle()
d = 12
e = d * @a

end #module
