Unity documentation says to use StartCoroutine() method for visible fading of renderer alpha but the following method works fine without StartCoroutine() with visible intermediate values. Is this way also right ?
using UnityEngine;
public class fade4 : MonoBehaviour {
private SpriteRenderer sr;
void Start ()
{
sr = GetComponent<SpriteRenderer>();
}
void Update ()
{
Fade();
}
void Fade()
{
Color c = sr.color;
c.a = c.a - 0.5f * Time.deltaTime;
sr.color = c;
if (c.a <= 0.1f)
this.enabled = false;
}
}
It will work yes, however, why create a class for a short existence when if you used a coroutine, you could also use it to fade in as well as out? Also, I would use Time.deltaTime so it reduces at a set speed no matter the framerate.
Yes, that is achieving the same thing, Coroutines can give you more control over when Fade is called. You could set a tick rate for your function or wait until the end of the frame for example.
