Combining Rotation = and Rotate()

Questions & Answers
1

Hello.

I’m trying to have an object look in the direction of its velocity, but also spin on its Z axis.

void Update ()
    {
        this.transform.Rotate(Vector3.forward, (500 * Time.deltaTime), Space.Self);
        this.transform.rotation = Quaternion.LookRotation(mVelocity); 
    }

The problem is that the two functions over-ride each other. If I comment out the .rotation function, the object spins properly but doesn’t look in the right direction. If I leave the rotation function in code, the oject points in the right direction, but doesn’t rotate on its axis.

Any suggestions on making these two play nicely together?

thanks
David

This might work:

 void Update()
    {
        var rot =  Quaternion.LookRotation(mVelocity);
        var spin = Quaternion.AngleAxis(500 * Time.deltaTime, transform.forward);
        transform.rotation = rot * spin;
    }
