Top-Down Direction help, (combat system)

[Prideravanok]

Hello, Need some help on how to go about making a top down direction(North,Northeast,South,etc)  system.

Used to aim attacks, and spawn skills to then shoot in said direction. preferably using character controller, and unity 2d's x and y coordinates no z. Not sure if that is relevant.

Any tip would be helpful, thank you in advance.
