alphaKeys not being updated
My issue is that alphaKeys isn't being updated after calling colorGradient.SetKeys, there is no change, whatsoever
public class BulletTrail : MonoBehaviour
{
public float Lifespan;
IEnumerator DestroyCoroutine()
{
float StartTime = Time.time;
var TrailRenderer = GetComponent<LineRenderer>();
while (Time.time - StartTime < Lifespan)
{
Debug.Log("Updating alpha to " + (1f - ((Time.time - StartTime) / Lifespan)));
GradientAlphaKey[] alphaKeys = new GradientAlphaKey[TrailRenderer.colorGradient.alphaKeys.Length];
Array.Copy(TrailRenderer.colorGradient.alphaKeys, alphaKeys, TrailRenderer.colorGradient.alphaKeys.Length);
alphaKeys[0].alpha = 1f - ((Time.time - StartTime) / Lifespan);
TrailRenderer.colorGradient.SetKeys(TrailRenderer.colorGradient.colorKeys, alphaKeys);
yield return null;
}
Destroy(gameObject);
}
void Start() => StartCoroutine(DestroyCoroutine());
}
