Hi everyone,
It appears that this prints every frame:
func _draw():
if previous_text != text:
print("Text changed: ", text)
Is that what func _draw(): does? I’d only need this to print once every time the text changes. Should I use some different function entirely or is there any way to interrupt this one?

Either of the code blocks you show should short circuit the function and prevent the contained code from executing until the text changes - but only if you UPDATE the value stored in the previous_text variable. You don’t show that happening, so I assume that’s the issue…
Something like this should work:
var previous_text = null
func _draw():
if previous_text != text:
previous_text = text
print("Text changed: ", text)
Your solution works perfectly again.
I tried
if previous_text != text:
previous_text = text
print("Text changed: ", text)
with the var previous_text = ""
before, so just "" instead of null.
What a difference this makes, thank you very much!
