I need to determine X,Y value, direction where the player is aiming in relative space to the player character. So if the player character is facing X direction in WS and aims there, then X = 1 and Y = 0, when the character faces Y direction in WS and aims there, then X = 1 and Y = 0, same values, because the player is still aiming and facing forward, not to the left or right.

Now I dont really know how to do it.

I have a vector that points towards the target (x), but it is in WS:

I need to determine where my character is aiming when standing still relative to the character. So if the player is aiming forward, then x should be 1 and y should be 0. If player is aiming abit to the right, then x should be 0,5 and y should be 0,5. If to the right, then x = -0,5 and y = -0,5.
