Better to use in-line variables to avoid alpha increasing too quickly

I initially made a mistake that was causing alpha to increase much too rapidly. It took me a moment to figure it out. I thought I’d pass it on: make sure you increment within the while loop, rather than doing what i did below. Calculating a separate variable outside the while loop means you increment by the wrong fixed amount.



        IEnumerator FadeOut(float time)
        {
            **float deltaAlpha = Time.deltaTime / time;**
            while (faderCanvas.alpha < 1)
            {
                faderCanvas.alpha += deltaAlpha;
                yield return null;
            } 
        }
    }

Quite right. If you’re lucky and the framerate holds steady, this could actually work, but it’s best to calculate it within the loop.
