Move sprite to mouse click position with forward facing rotation

Hi everyone,

The game i'm developing is top down 2D and I want the user to be able to explore the world.

I have some code that gets a the users mouse click position (raycast) and moves my sprite to that location. My problem is that I can't get the sprite to face the direction its traveling. If I move the sprite it faces the same direction as its default (i would describe it as north).

I have been through a few options with moving its z axis rotation value but none of them are smooth, or none of them work consistently. I have also tried to use Quaternion.Lerp but with erratic results.

Could anyone help me out on this one. I'm truly stumped.

Thanks, Chris.
