Controls how much the velocity that exceeds the velocity limit should be dampened.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public bool moduleEnabled = true; public float hSliderValueSpeed = 0.0f; public float hSliderValueDampen = 0.1f;

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

void Update() { var limitVelocityOverLifetime = ps.limitVelocityOverLifetime; limitVelocityOverLifetime.enabled = moduleEnabled; limitVelocityOverLifetime.limitMultiplier = hSliderValueSpeed; limitVelocityOverLifetime.dampen = hSliderValueDampen; }

void OnGUI() { moduleEnabled = GUI.Toggle(new Rect(25, 45, 200, 30), moduleEnabled, "Enabled");

GUI.Label(new Rect(25, 80, 100, 30), "Speed Limit"); GUI.Label(new Rect(25, 120, 100, 30), "Dampen");

hSliderValueSpeed = GUI.HorizontalSlider(new Rect(95, 85, 100, 30), hSliderValueSpeed, 0.0f, 2.0f); hSliderValueDampen = GUI.HorizontalSlider(new Rect(95, 125, 100, 30), hSliderValueDampen, 0.0f, 1.0f); } }
