Playing animations by velocity for the correct direction.

Worked on the script and got some progress so changed question to what I am dealing with now.

So I have a script for setting the animations by the velocity of the Rigidbody. This works fantastic. But now I am trying to overcome of what to do when the transform is rotated so the velocity's are changed between X and Z.

MY QUESTION IS: Is there another better way to do this? Am I going at this all wrong? If not...

Ok, my script works every where expect getting the Strafing animations to play correctly.

Running Code

 if(rigidbody.velocity.z <= -0.1f && rigidbody.velocity.x >= -4.7f && transform.eulerAngles.y >= 80 && transform.eulerAngles.y <= 180)
     {
         characterModel.animation.CrossFade("Run");
     }

Strafing Code

 if(rigidbody.velocity.x >= 0.1f && rigidbody.velocity.z <= 4.5f && transform.eulerAngles.y >= 0 && transform.eulerAngles.y <= 88)
         {
             characterModel.animation.CrossFade("StrafeRunRight");
         }

Basically what I am thinking is that I need something else that I could reference for when I am strafing. Since both running and strafing effect both X and Z when the transform is rotated.

I just can't think of what to do next. Any help would be appreciated. :)
