never mind , my problem was that when my 1st cube starts to LookAt(Cube2) all the axis start to change (X,Y,Z) all i wanted is the Z axis only , i fixed this using

var relativePos = Vector3 Cube2.position - Cube1.position; var rotation = Quaternion.LookRotation(relativePos); Cube1.rotation = rotation;

thanks for your help though

Please post some code and we'll be able to help better. We don't even know what language you are using.

I would say that use the same logic as what is working for the Y axis, but in the parameters 0 out the Y information, and put the information in the Z's place.
