Unity3D quick tip

..:: animate the rotation ::..

It's a pity, that the transform.LookAt() function has no possibility to animate the rotation.

So, we need to create such a functionality ourselves.

To do that, we need a speed variable, i set it to 12, because i find, this is a proper value. And we need a look target.

    float rotationSpeed = 12f;
    Transform lookTarget;

Next, we need a Rotate function, in which we get the direction vector, then we check, if we have a direction, if not, we do nothing. Next, we create the look rotation to the direction. And last, we lerp the rotation of transform.

    void Rotate() {
        Vector3 direction = lookTarget.position - transform.position;

        if(direction == Vector3.zero)

        Quaternion rotation = Quaternion.LookRotation(direction);

        transform.rotation = Quaternion.Slerp(transform.rotation, rotation, rotationSpeed * Time.deltaTime);

Now, we can call the Rotate function in the Update function.

    void Update(){
