Examples

using UnityEngine;// In this example we have a Particle System emitting aligned particles; we then emit and override the position and velocity every 2 seconds.public class ExampleClass : MonoBehaviour{    private ParticleSystem system;    void Start()    {        // A simple particle material with no texture.        Material particleMaterial = new Material(Shader.Find("Particles/Standard Unlit"));        // Create a Particle System.        var go = new GameObject("Particle System");        go.transform.Rotate(-90, 0, 0); // Rotate so the system emits upwards.        system = go.AddComponent<ParticleSystem>();        go.GetComponent<ParticleSystemRenderer>().material = particleMaterial;        // Every 2 seconds we will emit.        InvokeRepeating("DoEmit", 2.0f, 2.0f);    }    void DoEmit()    {        // Any parameters we assign in emitParams will override the current system's when we call Emit.        // Here we will override the position and velocity. All other parameters will use the behavior defined in the Inspector.        var emitParams = new ParticleSystem.EmitParams();        emitParams.position = new Vector3(0.0f, 0.0f, 0.0f);        emitParams.velocity = new Vector3(0.0f, 0.0f, -2.0f);        system.Emit(emitParams, 1);    }}
