Coroutine Animate over time

Jason Storey

The IEnumerator interface has three methods:

The first method, Co_OverTime, takes two parameters: the duration of the animation and a function to be executed on each animation frame.

The second method, onTick, takes three parameters: the duration of the animation, the animation curve to use (if provided), and a boolean flag indicating whether the animation should start automatically on frame tick or not.

The last method, AnimationCurve, takes only one parameter: a curve to use for the animation.

Library: Animation

IEnumerator Co_OverTime(float duration, Action<float> onTick,AnimationCurve curve = null)
{
  float timer = 0;  
  curve ??= AnimationCurve.EaseInOut(0, 0, 1, 1);  
  while (timer < 1)  
  {  
  timer += Time.deltaTime / duration;  
  onTick?.Invoke(curve.Evaluate(duration));  
  yield return null;  
  }  
}
