Setting AI to look at player using SetFocus

Ive got it working by the following, but now the AI is always looking at the player, even when running sideways. How would I set the AI to focus only for a brief period?

I have a very simple AI and Im trying to figure out how to get the AI to look at the player when they are damaged by them. I found the SetFocus node, but it doesnt seem to work. How can I achieve the AI looking at the player if I am standing behind them when I damage them.

I have been trying to figure out the same thing. If you follow my link below to my question, it may help you out a little. We have not got it working completely yet, but we are getting very close. Good luck!

You can unset or clear focus following a delay.
