Move sprite forward in Space.Self

Currently attempting something that looks like this:

Code (CSharp):

1.  
2.         if (Input.GetKey (KeyCode.W)) {
3.             Debug.Log ("Reaction!");
4.             transform.position += new Vector2(0, 5, Space.Self);
5.         }

But it doesn't take more than 2 arguments. What I'm trying to do, is make sprite move forward to it's own relative position. I have other script, which turns around the player, and actually changes sprite's rotation, I try to make it go in the direction of cursor. But I can't figure out how. Vector2.up, makes it go infinitely to the top, literally, but not in direction of cursor.

by the way, Space.Self is apparently not part of Vector2, what is it part of then? I forgot.

 

Vector2 only takes 2 aguments, x, and y.
Vector3 takes 3 arguments, but the 3rd one is the Z depth, and I doubt you want that for a 2d game.

You can use transform.forward to get the facing position of the object, and transform.right to get the right side, etc. These are always the forward and right sides of the object, even when it's rotated. Try em out!

Code (CSharp):

1. if (Input.GetKey (KeyCode.W)) {
2.             Debug.Log ("Reaction!");
3.             transform.position += transform.forward * 5
4. }

 

transform.forward got me WAY out in the Z, while my 2D game is YZ, I changed it to transform.position += transform.right / 10; and it worked just great.
