As you can tell from that thick, luscious error message, that ain't it chief. Sooooo, maybe:
But I don't want it to be a node. I want it to be an int. Apparently in GDScript, if you're writing a for loop, the for (variable) is always gonna be a node. Always and forever.
I didn't get a screenshot, but apparently the right answer is:
for i in button_container.get_children():
if i.disabled == false:
i.grab_focus()
But like with tabs that Blogger doesn't eat.
So of course, I immediately stepped on a rake and NEEDED i to be typed. Do you know how to do it?
Other sane languages would let you do i : whatever, but gdscript, you're typing that bad boy inside the loop.
Thanks! I hate it!
