Having trouble. Trying to fade out a sprite after 5 seconds over the course of a second or two.
After five seconds the sprite just disappears instantly. I got it from the manual specifically because it said it wouldn't do that. http://docs.unity3d.com/Manual/Coroutines.html The only changes made to the script was that I added the 5 second wait "startFade" (it was still disappearing immediately before I added that) and I had to change "renderer" to "GetComponent()"
[CODE]
using UnityEngine; using System.Collections;
public class FadeSprite : MonoBehaviour
{
public float fadeWait = 5;
void Start ()
{
StartCoroutine (startFade (fadeWait));
}
IEnumerator Fade()
{
for (float f = 1f; f >= 0; f -= 0.1f)
{
Color c = GetComponent<Renderer>().material.color;
c.a = f;
GetComponent<Renderer>().material.color = c;
yield return null;
}
}
IEnumerator startFade(float wait)
{
yield return new WaitForSeconds(wait);
StartCoroutine ("Fade");
}
}
[/CODE]
Sorry I'm not sure if the code tags worked. I read this http://forum.unity3d.com/threads/using-code-tags-properly.143875/ and tried doing what it said but I'm not sure.
Your color is faing way to quickly. Beside you should use Time.deltaTime to ensure it wouldn't be frame rate dependant like this:
IEnumerator Fade()
{
for (float f = 1f; f >= 0; f -= Time.deltaTime)
{
Color c = GetComponent<Renderer>().material.color;
c.a = f;
GetComponent<Renderer>().material.color = c;
yield return null;
}
}
This would last 1s. If you want it to last more just divide Time.deltaTime by some number.
It looks like the Fade() function is leaving the material.color at 0 when the FOR loop ends. If you want the sprite to re-appear then capture the color before the FOR loop and restore it at the end.
