Hello Dynamo people! We are looking at putting a little bit of love into the If Node - specifically enabling lacing with it, but want to do more and make sure it behaves how you wish it would! We are looking for feedback in this thread on how you think the If Node should function and are particularly interested in real-world examples :slight_smile: This could be examples you have currently worked around using DesignScript, Python or ZeroTouch nodes, or any manner of nested If statements. For a single list, we currently have the following solutions: Out-of-the-box demarcated in Teal @Andreas_Dieckmann’s awesome Clockwork solution in Orange The standard Python solution in Pink [image] We don’t want to break any existing workflows - so will either add another node or make sure the default behaviour (With lacing) still retains what is in existence today. The behavior for a double True or double False is as follows: [image] The behavior for an index matched list of True's and an index matched list of False's is as follows: [image] And finally, for an index matched list of random True's and False's is as follows: [image] Question to you all - does the behavior of the Clockwork nodes exhibit what is expected? If_Node.dyn (78.8 KB)

Great news, ScopeIf+ from Clockwork is what I use (design script)… I’m also intrigued by Marcel’s suggestion, would an extra input for ‘else’ ‘then’ etc. work?

Hey @Marcel_Rijsmus, do you have an examples where you would want to use both the If.Else and If.Then split nodes? I’m intrigued :slight_smile:

Split outputs might be helpful in some situations as well; i.e. separate pass/fail outputs as well as the current “combined” output.

I’ve updated the original post with more context - and another question! :smiley:

I think that there is another difference that the examples do not show, the case for a true list with different length than the false list. [grafik] The OoTB if node won´t return that last yellow when the test is false. Is this part of what will be addressed by adding lacing functionalities, or is it working as expected?

It’s very much not serving the Dynamo community correctly hence the ask! Appreciate the feedback @HalfBaked I did indeed miss this case :stuck_out_tongue: Oops.

Heya Thanks Sol, we all appreciate it :slight_smile: On a related note… Given that the ScopeIf node is pretty dangerous, could we make a big note for people to avoid it? Or rename it to be more explicitly for node building? (sorry if this breaks people’s graphs, but I can’t say I’ve ever seen it used) Thanks, Mark

This particular focus is on the basic If node, but we can definitely also think about ScopeIf :slight_smile: We can’t make any breaking changes (Unless very warranted) to existing graphs until we hit a major version - i.e Dynamo 3.0, of which a single change like this wouldn’t precipitate said upgrade. We could change the hover interaction on help however.

Hi @solamour I was thinking to make the nodes more self explanatory. IF ELSE could be used as: Make a branch that executes when the IF statement results in true. Else run a second branch of the script. I just think it would be easier to understand the node. IF title == 'The Hobbit' OR primary_author == 'Tolkien' THEN RETURN 'Middle-earth' ELSE RETURN 'Earth' END

what values are returned is different than what code is actually executed - this is why scopeIF node exists and I think it’s important to discuss here as well…
