$ 0 0 I'm using this little coroutine to fade away some UI text: Code (CSharp): IEnumerator Fade() { float a = Message.color.a; float d = a/4f; float t; while(a>0) { yield return null; t = Time.deltaTime; Message.color = new Color(1f,1f,1f,a); a -= d*t; Y += 15f*t; RectTrans.anchoredPosition = new Vector2(0f,Y); }... Changing text color causes a dramatic performance loss
