A quick way is to transform.LookAt(target) and then erase the x and z rotations. Assuming you want something like an RTS character than never leans over

 void Update ()
 {
     // Look at including x and z leaning
     transform.LookAt(target);
 
     // Euler angles are easier to deal with. You could use Quaternions here also
     // C# requires you to set the entire rotation variable. You can't set the individual x and z (UnityScript can), so you make a temp Vec3 and set it back
     Vector3 eulerAngles = transform.rotation.eulerAngles;
     eulerAngles.x = 0;
     eulerAngles.z = 0;
 
     // Set the altered rotation back
     transform.rotation = Quaternion.Euler(eulerAngles);
 }

Use these

Learn about them here

Without more info I cannot help you further.

 var target : Transform; 
 
 // Rotate the Object every frame so it keeps looking at the target 
 function Update() {
     transform.LookAt(target);
     
 }

Dont't forget to mark the question as answered and give a possable thumbs up.

Also you could add constantForce.relativeForce = Vector3(0, 0, 1); to make the object move forward at a constant speed.

Could you give me an example script

sure, you have to explain what you want to do a bit more. Is it like a tire rolling toward something or more like an object pivoting around another object?

i'm trying to create an ai script, i just can't wrap my brains around how to make the enemy face towards the player.

             transform.rotation = Quaternion.LookRotation (target.transform.position - transform.position);
             transform.rotation = Quaternion.Euler(0, transform.rotation.eulerAngles.y, 0);

rotate towards player around world y:

 float x = transform.rotation.eulerAngles.x;
 float z = transform.rotation.eulerAngles.z;
 Quaternion tempRotation = Quaternion.LookRotation(target.transform.position - transform.position);
 transform.rotation = Quaternion.Euler(x, tempRotation.eulerAngles.y, z);
