public float lifetimeMultiplier ;

説明

A multiplier for ParticleSystem.TrailModule.lifetime.

This is more efficient than accessing the whole curve, if you only want to change the overall lifetime multiplier.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public float hSliderValueLifetime = 1.0f;

void Start() { ps = GetComponent<ParticleSystem>();

var main = ps.main; main.startColor = new ParticleSystem.MinMaxGradient(Color.red, Color.yellow); main.startSize = 0.1f; main.startLifetime = 1.5f;

var trails = ps.trails; trails.enabled = true;

var psr = GetComponent<ParticleSystemRenderer>(); psr.trailMaterial = new Material(Shader.Find("Sprites/Default")); }

void Update() { var trails = ps.trails; trails.lifetimeMultiplier = hSliderValueLifetime; }

void OnGUI() { GUI.Label(new Rect(25, 40, 100, 30), "Lifetime");

hSliderValueLifetime = GUI.HorizontalSlider(new Rect(95, 45, 100, 30), hSliderValueLifetime, 0.0f, 1.0f); } }
