public float angularVelocity;

Description

Override the angular velocity of particles this system emits.

This value will be ignored if the Particle System uses either of the velocity modules.

See Also: ParticleSystem.Particle.angularVelocity.

using UnityEngine;

// In this example we have a Particle System emitting aligned particles; we then emit and override the rotation speed 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 rotation speed. All other parameters will use the behavior defined in the Inspector. var emitParams = new ParticleSystem.EmitParams(); emitParams.angularVelocity = 180.0f; system.Emit(emitParams, 10); } }
