    "facing"?

    tangent Theta = deltaY / deltaX

    So, your vector may be in the form (Xstart,Ystart) to (Xend,Yend)

    So
    Theta = ArcTan ( (Yend-Ystart) / (Xend-Xstart) )

    Watch your quadrant and radians/degrees
    "atan2" can handle the the quadrant issue.

    Degrees * PI / 180 = Radians
