public ParticleSystem.ForceOverLifetimeModule forceOverLifetime;

Description

Script interface for the ForceOverLifetimeModule of a Particle System.

Apply forces to particles using this module. Forces are applied to the particle velocities on each frame.

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;

[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var fo = ps.forceOverLifetime; fo.enabled = true;

AnimationCurve curve = new AnimationCurve(); curve.AddKey(0.0f, 0.1f); curve.AddKey(0.75f, 1.0f); fo.x = new ParticleSystem.MinMaxCurve(1.5f, curve); } }
