Is there some formula that'd return as follows:

   135  90   45
      \  |  /
       \ | /
        \|/
180 <----o----> 0 or 360
        /|\
       / | \
      /  |  \
   225  270  315
-----------------------
flipX(45) //returns 315
flipY(45) //returns 135
flipX(225)//returns 135
flipY(225)//returns 315

I may be misunderstanding, but could you just flipX() the value, then flipY() the value flipX() returned?

I don't have these procs. I need the programming that would make these procs work without having to brute force it.

Oh, alright. I understand your question now. I'll see what I can come up with.

I've already figured out flipx().
I just need flipy() now! (:

How about doing 180-Angle?

Yeah, 180-Angle works. You need to do negative checks though. If it's negative, just add the negative to 360 and that is your angle. (180-225=-45 : 360+-45=225)
