ParticleEmitter.emit

Description

Должны ли частицы испускаться автоматически каждый кадр?

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    IEnumerator Start() {
        ParticleEmitter emitter = GetComponent<ParticleEmitter>();
        emitter.emit = true;
        yield return new WaitForSeconds(3);
        emitter.emit = false;
    }
}
