Hello,
> I am a new user for yade
welcome :-)
next time please provide also a link to the script
This pattern is to easy switch between two different scenarios
Suppose:
###
if 0:
createLoosePacking() # possibly a long code block
else:
createDensePacking() # possibly a long code block
###
As it is, with "if 0:", is equivalent to (as the "if 0:" block is never
executed and therefore "else" is always executed):
createDensePacking() # possibly a long code block
If you change it to
###
if 1:
createLoosePacking() # possibly a long code block
else:
createDensePacking() # possibly a long code block
###
then it is equivalent to (as "if 1" is always executed and therefore "else" is
never executed):
createLoosePacking() # possibly a long code block
This way you can choose one scenario or the other just by altering 0/1
after the "if" keyword.
HTH
cheers
Jan
