Change Animation According to Direction

Hello,

I'm working on a RTS game,

I have a character that has 5 animations attached: Idle, Run, RunLeft, RunRight, RunBack. What I need to do, is use these animations for my character depending on the direction he's running.

By default, the character will always run in a forward direction to wherever I click, so I only need to use the Run animation.

But, when the character comes into close proximity with an enemy, his rotation will always face the enemy, but will continue to run in the direction of wherever I clicked on the map.

This is where I need the change the animation playing, as he may be facing North at the enemy, but running East, so I will need to play the RunRight animation instead of the Run (forward) animation.

I need to somehow use the current character rotation against the marker (the click location of the mouse, on the map) so select between my animations:

 //If we are in proximity to an enemy, then face it, but continue to run towards click marker
 if(finder.target){
     transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(finder.target.position - transform.position), turnSpeed * Time.deltaTime);
     transform.position = Vector3.MoveTowards(transform.position, nav.CurrentTargetWaypoint, runSpeed * Time.deltaTime);
 }
 //Otherwise, face the the click marker, and run towards
 else{
     transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(nav.CurrentTargetWaypoint - transform.position), turnSpeed * Time.deltaTime);
     transform.position += transform.forward * runSpeed * Time.deltaTime;
 }
 
 transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0);
 
 //Animation control
 if(hasAnimation){
     anim.characterToAnimate.animation.CrossFade(anim.Run.name, .1f);
 }
