How to solve this small problem...

I end up with this situation:

Have the Value A

A has some data or

A is null, it does no have data.. no values, like if you did not select any thing with the curve parameter etc...

I want to be able to say: IF A has data, then = to 1, and if A does not have data, then, set it to 0.

How would I go to do that? Is there a NULL eval parameter or component?

Thanks

Andres

There is such a component. Sets>List>Null Item

This is what I have now, but I do not know if this is ok

What you're really after is a simple way to convert True/False to numbers. Any time you put a Boolean into something that requires a number then GH converts True to 1 and False to 0

The Not component will reverse that result so 1s become 0s etc

Danny

But, if the input to the BOOLEAN is empty too. The component would not work... so, I may not get the TRUE/FALSE....

Danny, can you check the photo I just uploaded? Tell me if I am 100% right or LOST! :-)

Thanks..

Yes I think your right, notice I had to put the Referenced Point through another component to get the nulls also. From there you can use the Null Item to get your Booleans
