Hey Everyone,
First of all, Merry Christmas!!! Anyways, is it possible to make a sensor sense objects in a line? To be more specific, say I have two objects parallel to each other. I want one object to be able to detect the other object, but only in a straight line. I could use collision, but I'd prefer sensors. Thanks for any help in advance.

i dont belive so, but you can have it detect scripted objects

I am not sure I understand what you are asking.. A sensor can detect up to 95 meters away.. and can be configured to detect anywhere from a full sphere around, to half a sphere, down to a very narrow cone shape.. This would almost be a line if the cone were narrow enough. Maybe that helps..
You can find some excellent explanations and visualizations here:

I think to get a 'real' line you would have to do the math on their positions.

That way it would me independent of the sensor location

You do - you can't just narrow the cone down to a very thin one, because the centre of the detected object has to be within the cone, and thus you'd have to be very lucky to hit it.

I'm not precisely sure what is being asked here either but this might be useful as an example of the maths concerned, though I'm sure it could be tidied up:
