Sprite Color Lerp during Length of Sprite Animation

Hey all,

I’m a bit stuck and for some reason I can’t figure this math out.

So when I tap the screen in my game it triggers the main character sprite to play an animation (0.75 seconds long) and it triggers a method that lerps the color of the sprite using Color.Lerp(old, new, timeValue);

Now my problem is that I want the lerping to last as long as the animation so a total of .75 seconds of Lerpage!
But that doesn’t happen… my math causes my lerping to finish when the animation is only half way complete.

I’m using the following code can anyone help me figure out my error?

	private IEnumerator ColorLerp()
	{
		lerpingColors = true;
		bool doneFading = false;
		float time = 0;
		float scaledValue = 0;

		//then start fading based on animation
		Debug.Log ("Total Animation time = : " + totalAnimationLength);
		while (!doneFading)
		{
			time += Time.deltaTime;
			scaledValue = time / totalAnimationLength;
			Debug.Log("Time : " + time + " Value: " + scaledValue + " " + mySpriteRenderer.color);

			mySpriteRenderer.color = Color.Lerp(mySpriteRenderer.color, GetColor(), scaledValue); 
			yield return 0;

			if(mySpriteRenderer.color == GetColor()) Debug.LogWarning("Color Lerping finished but time isnt");
			if(scaledValue >= 1f || mySpriteRenderer.color == GetColor())
			{
				doneFading = true;
				mySpriteRenderer.color = Color.Lerp(mySpriteRenderer.color, GetColor(), 1f); 
			}
		}
		lerpingColors = false;
		if(GodMode) GodMode = false;
		Debug.Log ("Done Lerping Colors " + scaledValue + " " + totalAnimationLength);
	}

when scaledValue == .5~ the lerping is already at the end color return variable from the GetColor() method.

Thanks for any help.

Solved: it wasn’t my math that was the problem. Problem was I was using the updated sprite rendere color instead of a from color value. So my from value was constantly updating messing up my lerping

Here is my updated method that works

	private IEnumerator ColorLerp()
	{
		lerpingColors = true;
		bool doneFading = false;
		float time = 0;
		float scaledValue = 0;
		Color fromColor = mySpriteRenderer.color;
		//then start fading based on animation
		Debug.Log ("Total Animation time = : " + totalAnimationLength);
		while (!doneFading)
		{
			time += Time.deltaTime;
			scaledValue = time / totalAnimationLength;
			Debug.Log("Time : " + time + " Value: " + scaledValue + " " + mySpriteRenderer.color);

			mySpriteRenderer.color = Color.Lerp(fromColor, GetColor(), scaledValue); 
			yield return 0;

			if(mySpriteRenderer.color == GetColor()) Debug.LogWarning("Color Lerping finished but time isnt");
			if(scaledValue >= 1f || mySpriteRenderer.color == GetColor())
			{
				doneFading = true;
			}
		}
		//just to be sure
		mySpriteRenderer.color = GetColor(); 

		lerpingColors = false;
		if(GodMode) GodMode = false;
		Debug.Log ("Done Lerping Colors " + scaledValue + " " + totalAnimationLength);
	}
