Make an object rotate - seek another object

Good evening. I am trying to make an object detect and rotate toward another object when it gets near it. Like a watchtower, but I have no idea if there is a way except scripting. Any advice?

Near sensor with a track actuator? If you don’t want to script, just set a near sensor up with an “edit object” track actuator attached. When object A is within range of object B, have object B track to object A. Should be pretty simple.

red baron is right, just something like this

near----------------------------------and--------------------------------edit object: track to [object]

Thank you very much. You two helped me a lot.

Is it possible to track any object that gets within range using the method you guys described?
