ParticleSystem.velocityOverLifetime

Descripción

Script interface for the Particle System Velocity over Lifetime module.

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);
    }
}
