C# Unity c->将骨骼旋转到目标向量3

我想操纵骨骼，这样它可以在操纵完成后回到初始旋转，这是我的代码

void toInitialRotation(Transform theBone, Quaternion theInitialRotation)
{
    //bone.rotation = initialRotation;  //this work but move instantly not animated
    
    var step = 20 * Time.deltaTime; // The step size is equal to speed times frame time.

    // Rotate our transform a step closer to the target's.
    theBone.rotation = Quaternion.RotateTowards(bone.rotation, theInitialRotation, step); //it's work and animated well
}

上面的代码工作得很好，动画效果也很好，但它是基于步长工作的，我的问题是如何使它基于时间工作，例如，如果给定的时间是3秒，那么骨骼。旋转必须在3秒达到初始旋转，并在那里停止。 感谢您的帮助

您可以使用和类似的

IEnumerator toInitialRotation(Transform theBone, Quaternion targetRotation, float duration)
{
    // If there is no duration immediately jump to the target rotation and terminate the routine
    if(time <= 0)
    {
        theBone.rotation = targetRotation;
        yield break;
    }

    var currentRotation = theBone.rotation;
    
    var timePassed = 0f;  
    while(timePassed < duration)
    {
        // Will move from 0 to 1
        var factor = timePassed / duration;

        // Interpolates from the current to the target rotation
        theBone.rotation = Quaternion.Slerp(currentRotation, targetRotation, factor);

        // Increase by the time passed since last frame
        timePassed += Time.deltaTime;

        // Tells Unity to "pause" the routine, render this frame
        // and continue from here in the next frame
        yield return null;
    }

    // Just to be sure set the rotation fix when done
    theBone.rotation = targetRotation;
}
