I'd like to create node groups which behave a little differently depending on whether particular input nodes are wired or not. Is there a way to test if they are wired or not?
I'd prefer not to use the "sentinel value" method, because I want to use the defaults as reasonable values that are set when I first place the group node, before I wire anything up, and also as a reasonable value to reset the input to when I need to. If I set the default to a sentinel value, then I have to make that value something outside of the expected input range in order to avoid accidentally tripping it during normal use.
I'd like a Is Input Wired(InputName:str) -> Boolean
node. Does such a thing exist?
