Make one object look at another?

Hello. How can I make one object look at another, but only along one axis(for example, the object will only look at the other by rotating along the x axis and will not move at all along the y/z axes as part of looking at the object)?

you can find the angle to another point by using arctan like this

` angleToObject = Math.Arctan((position.x - other.position.x)/(position.y - other.position.y)); `

then just rotate to that angle.

edit

in this example you would be rotating around the z-axis but you could use this same method with any other axis.

Try making the object to look at a new point, that's a combination of the coordinates of the two objects, for example:

ObjectA must look ObjectB but only in its X axis:

ObjectA.transform.lookAt( new Vector3 ( 
    ObjectB.transform.position.x, 
    ObjectA.transform.position.y, 
    ObjectA.transform.position.z 
    ) );
