2D Shooter - shooting forward at the current rotation

Hi! So I have a script where i rotate an enemy to face the player.Then I want the enemy to shoot a projectile at the angle the enemy is.I have tryed alot of different codes from the internet to shoot the projectile forward but instead my projectile does not move at all.

this causes the same thing:
“rigidbody2D.AddForce(Vector3.forward * Speed)”
I also tryed
rigidbody2D.AddForce(transform.forward * Speed)"
In both cases the projectile does not move.
Any help is apreciated.Thank you

alright i made it work by modifying your code:
here is the final one:

 rigidbody2D.AddRelativeForce(new Vector3 (0,Speed));

Submit that code as answer and i will accept it.
Thank you

Playing around with my code and his own variation, RedDevil accepted this collaborated code as an answer:

 rigidbody2D.AddRelativeForce(new Vector3 (0,Speed));

I’m glad I could help, even though you did most of the work!
