public ParticleSystem.Burst(float _time, ParticleSystem.MinMaxCurve _count);
public ParticleSystem.Burst(float _time, ParticleSystem.MinMaxCurve _count, int _cycleCount, float _repeatInterval);

Parameters

_timeTime to emit the burst.
_minCountMinimum number of particles to emit.
_maxCountMaximum number of particles to emit.
_countNumber of particles to emit.
_cycleCountNumber of times to play the burst. (0 means indefinitely).
_repeatIntervalHow often to repeat the burst, in seconds.

Description

Construct a new Burst with a time and count.

// Create a looping Particle System. // At 0, 1 and 2 secs the number of particles in each loop // are changed from 10, to 50, then to 100. // The loops repeat after 3 seconds.

void Start() { // create a red ground plane GameObject ground = GameObject.CreatePrimitive(PrimitiveType.Quad); ground.transform.rotation = Quaternion.Euler(90, 0, 0); ground.transform.localScale = new Vector3(10, 10, 10); ground.GetComponent<Renderer>().material.color = Color.red;

// rotate the GameObject so particles rise up in the y-axis gameObject.transform.rotation = Quaternion.Euler(-90, 0, 0); gameObject.AddComponent<ParticleSystem>();

// create the ParticleSystem ParticleSystem ps; ps = gameObject.GetComponent<ParticleSystem>();

ps.Stop();

// set the MainModule default values var main = ps.main; main.startColor = Color.yellow; main.duration = 3;

// create a cone and change it into a cylinder var shape = ps.shape; shape.shapeType = ParticleSystemShapeType.Cone; shape.angle = 0.0f; shape.radius = 2.0f; shape.radiusThickness = 0.0f;

// use the passed in material gameObject.GetComponent<ParticleSystemRenderer>().material = part;

// set up the emission to generate particles var em = ps.emission; em.enabled = true; em.rateOverTime = 0;
