public float sizeMultiplier ;

Descripción

A multiplier for ParticleSystem.SizeOverLifetimeModule.size.

Changing this property is more efficient than accessing the entire curve, if you only want to change the overall size multiplier.

using UnityEngine;
using System.Collections;

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

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

var sizeOverLifetime = ps.sizeOverLifetime; sizeOverLifetime.enabled = true; sizeOverLifetime.sizeMultiplier = 1.0f;

var psr = GetComponent<ParticleSystemRenderer>(); psr.material = new Material(Shader.Find("Sprites/Default")); // this material renders a square billboard, making it easier to see the size }

void Update() { var main = ps.main; main.startLifetimeMultiplier = hSliderValue; }

void OnGUI() { hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 1.0f, 5.0f); } }
