Question How to move game object forward at angle?

I have a bullet that turns toward the player and i need it to move forward at the angle it is facing. So basically i am making a heat seeking bullet. Also i have this code for turning the bullet towards the player and it isnt working right:

Code (CSharp):

1. var dir = player.position - Camera.main.WorldToScreenPoint(transform.position);
2.             var angle = MathF.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
3.             transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
4.  

idk how the math works is that code.

 

if the bullet turns toward the target, and only moves forward, it will move towards the target.

 

idk how to move forward

 

I'm not sure if your joking.. but if not, I'd look into beginner tutorials as they cover something as simple as move forward.

Easiest way I know off hand is just translate:

transform.Translate(0, 0, moveSpeed);
