ParticleSystem.limitVelocityOverLifetime

説明

Script interface for the Particle System Limit Velocity over Lifetime module.

This module reduces particle velocities by either applying drag or simply reducing velocity over time.

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 lv = ps.limitVelocityOverLifetime;
        lv.enabled = true;
        lv.dampen = 0.5f;

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