I’m getting this error, but I can’t figure out what its getting caught up on. From what I understand the “accessed none” flag is it usually comes up when a reference isn’t set. But it’s coming up on a branch and a Rotator variable? What gives? The variable is only referenced in this function.
Check out video #27 in this series. Should point you in the right direction.
Your function input “target” doesn’t seem to be valid. If you walk back from the branch node you will see it needs a valid reference to “target” to get the data necessary for the “<” float comparison.
