public float rateOverDistanceMultiplier;

Description

Change the rate over distance multiplier.

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

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public float hSliderValue = 5.0f;

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

var main = ps.main; main.simulationSpace = ParticleSystemSimulationSpace.World;

var shape = ps.shape; shape.enabled = false;

var emission = ps.emission; emission.rateOverTime = 0.0f;

// add a sphere so we can see our transform position as it moves var sphere = GameObject.CreatePrimitive(PrimitiveType.Sphere); sphere.transform.parent = ps.transform; }

void Update() { var emission = ps.emission; emission.rateOverDistanceMultiplier = hSliderValue;

ps.transform.position = new Vector3(Mathf.Sin(Time.time) * 2.0f, 0.0f, 0.0f); }

void OnGUI() { hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 1.0f, 20.0f); } }
