title: Fade out individual particles on collision?
body: <p>I'm currently tring to fade out each individual particle from a particlesystem on collision, but I'm having a hard time getting it to work. Currently when a particle from the particlesystem collides with something it starts fading the start color(this is a asumption) and it will continuesly do so with the upcoming particles. These also need to be fading out when they collide, instead of fading out based on the previous particle collision.</p>
  
  <p>This is the code as of now, any advice is very welcome.</p>
  
  <pre><code>void OnParticleCollision(GameObject other)
  {        
      int collCount = _ps.GetSafeCollisionEventSize();
  
      if (collCount &gt; _collisionEvents.Length)
          _collisionEvents = new ParticleCollisionEvent[collCount];
  
      int eventCount = _ps.GetCollisionEvents(other, _collisionEvents);
  
      for (int i = 0; i &lt; eventCount; i++)
      {
          FadeParticleSystem();
      }
  }
  
  private void FadeParticleSystem()
  {
      ParticleSystem.Particle[] particles = new ParticleSystem.Particle[_ps.particleCount];
  
      _ps.GetParticles(particles);
  
      for (int p = 0; p &lt; particles.Length; p++)
      {
          Color col = particles[p].color;
          col.a -= col.a * 3 * Time.deltaTime;
          particles[p].color = col;
      }
  
      _ps.SetParticles(particles, particles.Length);
  }
  </code></pre>
