public ParticleSystem.VelocityOverLifetimeModule velocityOverLifetime;

Description

Script interface for the VelocityOverLifetimeModule of a Particle System.

This module sets the velocity of particles during their lifetime.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var vel = ps.velocityOverLifetime; vel.enabled = true; vel.space = ParticleSystemSimulationSpace.Local;

AnimationCurve curve = new AnimationCurve(); curve.AddKey(0.0f, 1.0f); curve.AddKey(1.0f, 0.0f); vel.x = new ParticleSystem.MinMaxCurve(10.0f, curve); } }
