Convert Script bools to blend tree

Unity Engine

How would i convert the following into a blend tree?

if (offsetY < 20 && offsetY > -20)
                    anim.SetBool("RunForward", true);
                else
                    anim.SetBool("RunForward", false);
                if (offsetY < 230 && offsetY > 130)
                    anim.SetBool("RunBackward", true);
                else
                    anim.SetBool("RunBackward", false);
                if (offsetY >= 20 && offsetY <= 130)
                    anim.SetBool("RunRight", true);
                else
                    anim.SetBool("RunRight", false);
                if (offsetY >= 230 || offsetY <= -20)
                    anim.SetBool("RunLeft", true);
                else
                    anim.SetBool("RunLeft", false);

it is a rotation value of y with the offset of -45 to make up = 0

to be more specific i’m trying to get a top down camera going and it works with the following:

if (Input.GetKey(KeyCode.W))
                {
                    rotationYRatio = transform.rotation.eulerAngles.y / 360;
                    anim.SetFloat("RotationY", rotationYRatio);
                }

The problem is…it needs to be possible to do the other directions somehow. the blend tree works great now with w.
