I’d like to create a filter where I check if a text block’s contents = null, and then have that either trigger or not trigger something.
I saw the text compare block, but it outputs the contents of block B.

If you’re looking for if a list is empty, using a List Count and a Filter set to 0 should do it.
So what I might want to do is send the test text to a list, and then filter the list?
Tried this, but the filter reads even an empty item in a list as an existing item
Oh you’re looking for Text, not a Text List.
You’re just trying to see if it equals “null”?
Text Compare works for that.
Just have the Text go into the “B” input, and set “A” inside of the behavior to “null”
Trying this but it sends a 0 out from B no matter what I put into B
(it says “null” inside the text compare block, is that what you meant?)
maybe just don’t put anything in the text compare?
You’re looking for a blank Text, or Text that contains “null”?
If you’re looking for a blank Text, you could leave the Text Compare empty, but I haven’t used an empty Text Compare so maybe it would not output properly.
If that’s the case, you can use the Text Length behavior, which should output 0 if the Text is empty (Text Length outputs the number of characters inside the Text input)
Putting nothing into the text seems to work in terms of output, now I just need to figure out how to turn the outputs into a normal 1/0 trigger.
Ok, the two paths are being “activated” by receiving a zero! And zero works to activate a block. SOLVED
