Resolved Rotate fireball in direction of flight

I want to rotate my 2D fireball in the direction of his flight.

Code (CSharp):

1. // Shoot fireball in direction of player
2. targetDirection = ((_targetTransform.position - transform.position)).normalized;

This is how I calculate the direction of the fireball. And it works perfectly fine and now I need to rotate the fireball in the direction of the flight.

I tried:

Code (CSharp):

1. // Rotates fireball in direction of player
2.             Quaternion rotation = Quaternion.LookRotation(_targetDirection, Vector3.up);
3.             rotation = new Quaternion(0, 0, rotation.y, 0);
4.             this.transform.rotation = rotation;

Since this is a 2D game I don't want any rotation on the x and y axis, only on the z axis.

Can someone tell me how I can rotate my fireball in the direction of the player. If you need more information I'm happy to help. Thanks in advance.

 

Thank you this worked perfectly. My question is solved.
