Testing if the player is holding a direction?

I'm working on a third person stealth game. I want include a mechanic in which, if you are snapped to cover, move up to a corner, and continue holding the vague direction of the corner, you will peek around the corner. I have most of this implemented and it should work, I just don't know how to test whether the player is holding a direction or not. I will include my current implementation (although some of it might not make sense without context of the rest of the code). It currently ends in an infinite loop. If anyone has any ideas, that would be amazingly helpful. Thanks!

void PeekCover(int rotDir) { int count = 0; float rotation = Mathf.Round(closest.transform.localEulerAngles.y + closest.transform.parent.transform.localEulerAngles.y); float srotation = Mathf.Round(swapper.transform.localEulerAngles.y + swapper.transform.parent.transform.localEulerAngles.y); bool inCorner = true; Vector3 dirCheck = movement;

         //check if against a wall
         if(rotDir == 1)
         {
             if(srotation == 90)
                 inCorner = false;
         } else if(rotDir == 2)
         {
             if(srotation == 270)
                 inCorner = false;
         } else if(rotDir == 3)
         {
             if(srotation == 180)
                 inCorner = false;
         } else if(rotDir == 4)
         {
             if(srotation == 0)
                 inCorner = false;
