How do I lerp to a color?
I have a sprite that, when I mouse over it, I want it to appear slowly. Like a glow behind the player. But I don't know how to do it exactly.
I tried using lerp. And I got nothing. The sprite appears on OnMouseEnter and dissapears in OnMouseExit.
I tried OnMouseOver as well.
So far nothing seems to work.
Put your sprite in the scene, add collider to it and the script below. You can use OnMouseEnter simply turning it into coroutine (or you can create a separate coroutine and run it from "normal" OnMouseEnter). Here's the code:
private SpriteRenderer sr;
private void Awake()
{
sr = GetComponent<SpriteRenderer>();
sr.color = new Color(1f, 1f, 1f, 0f);
}
IEnumerator OnMouseEnter()
{
Color start = sr.color;
Color target = new Color(1f, 1f, 1f, 1f);
float t = 0f;
float duration = 3f;
while(t < 1f)
{
t += Time.deltaTime / duration;
sr.color = Color.Lerp(start, target, t);
yield return null;
}
}
