f < 0 || f > UINT_MAX "Run-Time Error"

Hi, how do I prevent the error? This is what I am doing in code:

public class FadeParticles : MonoBehaviour {

private void Update() {
    FadeTheseParticles();
}

private void FadeTheseParticles() {

    ParticleEmitter pEmitter = GetComponent<ParticleEmitter>( );
    if (pEmitter.maxEmission > 0) {
        pEmitter.maxEmission -= 20 * Time.deltaTime;
    }
    else 
        Destroy(gameObject); 
}

}

Getting the error: f < 0 || f > UINT_MAX How can I prevent it? What is causing it? Are there better ways to get a smooth fade out of particles? If so, what are they?

You are subtracting from an unsigned integer (maxEmission). Unsigned can't go negative. So you need to check it before you subtract, or something, perhaps

if (pEmitter.maxEmission > (20 * Time.deltaTime))
  pEmitter.maxEmission -= 20 * Time.deltaTime;
else
  pEmitter.maxEmission = 0;
