I am animating a box onto a panel (on a Canvas) using a simple LERP in a Coroutine. I take a duration parameter, normalize it, and then apply the LERP. However, I am noticing that the amount of time for the LERP to do it's thing is 2x the time I expect.
- ie: when duration = 1.0f, then it
takes 2 seconds to perform the LERP (as indicated in my Debug.Log messages below)
- ie: when duration = 0.5f, then it
takes 1 seconds to perform the LERP
What am I missing? Is my WaitForSeconds impacting the calculation? And if so, why is this the case?
protected IEnumerator SlideIntoPanelHelper (float duration)
{
Debug.Log("Sliding into place at Time: " + Time.time);
float i = 0.0f;
float step = 1.0f / duration; // normalize the duration to [0..1]
RectTransform rt = GetComponent();
Vector3 start = rt.anchoredPosition3D;
Vector3 end = rt.anchoredPosition3D;
end.x = 0;
while (i <= 1.0f) {
float ndt = step * Time.deltaTime;
i += ndt;
rt.anchoredPosition3D = Vector3.Lerp(start, end, i);
yield return new WaitForSeconds(0.02f);
}
Debug.Log("Sliding into place COMPLETE at Time: " + Time.time);
}
