Ai script for side to side player tracking?

I have an enemy that's a claw, (like in a claw game)
And I need a script that makes it track the player side to side, and grab at them,
Does anyone have a script for that?

You can try MistSonata's code from here:

Also I just now wrote about a small quirk with doing this sort of behavior using AI Scripts that might be relevant for how you intend to use it:

Thanks for the answers, I'll try that script tonight.
