How to flip 2D object, mine isnt working nor any others i can find.

this is the program

if (Input.GetKeyDown (KeyCode.A)) {
GetComponent()transform.localScale.x = -14;
}

Error expecting ‘;’
Error Unexpected sumbol ‘.’ expecting ‘)’,‘,’,‘;’,‘[’, or ‘=’

anyone know what I’m doing wrong?

No big deal, you are just using GetComponent() a bit wrong.
If you need to use GetComponent there are a few ways to do it, but by the looks of things you shouldnt need to, simply use:

if (Input.GetKeyDown (KeyCode.A)) { transform.localScale.x = -14; }

or better yet

if (Input.GetKeyDown (KeyCode.A)) { transform.localScale.x = -transform.localScale.x; }
