couple lists comparison issue

Hi there!

I am working now on an algorythm, which as a result gives me a list of 'true/false' data. I'd like to use this alg 2 or 3 times at the same time and compare those lists in a way in which :

- if, at same location in those lists shows at least one 'true' then it counts it as a true or as 1.

and if, there are all 'false' then it comes up as a false or 0.

for expample:

false, false, true = true

false, false, false = false

true, true, false = true

etc.

And i have no bloody idea how to do that(fighting for 5 hours already...). Is it possible to make it using 'standard' grasshopper components or it requires some custom scripting?

Do you just mean "Gate Or"? That allows you to add/subtract inputs with the ZUI. Any single "True" among your list of inputs will return "True".

Hi!

try mass addition and test if result >= 1.

mass addition doesn't respect 'true/false' input list at mine computer... :/ but thank You!

This doesn't work? (or doesn't give you the wanted result?)

edit: Damn, didn't see the "or" stuff... sometimes things or so simple...

Mh..i have no idea about how i would do that with the 'standard' components. But indeed you can do that with a scripting component. The input accepts datatrees with either strings or booleans on its branches.

Thank you Thomas, I tried to link your script to my lists but those are 3 different lists, and I have no clue how to convert those into this format : true, false, true with ',' in between... But thir "OR' component seems to wok just as I wanted. Thank you for help! :)
