ParticleSystem.velocityOverLifetime

Descripción

Script interface for the Particle System Velocity over Lifetime module.

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);
    }
}
