How to set Y Rotation in 2D

Hello

I was working on AI, and this part makes random crazy rotation for enemy and it's invisible.

Code (CSharp):

1. Collider2D followPlayer = Physics2D.OverlapCircle (transform.position, attackRange, LayerMask.NameToLayer ("player"));
2. transform.LookAt(target.position);
3. transform.Translate(moveSpeed * Vector3.forward * Time.deltaTime);

If I pause the game and set rotation to 0, 0, 0 enemy is visible. Only Y is important.
Rotation of my player is at 0, 0, 0.

So how can I set rotation to 0 in script for 2D?

 

You usually only rotate around Z when dealing with rotations in unity 2D. Use Mathf.Atan2 to find the z rotation, given a direction vector.

 

I put transform.eulerAngles = new Vector3 (0, 0, 0); in all places in the code ( Hopefully that won't be a problem).
Thanks anyway
But now enemies stack on each other when they follow me
