public bool multiplyDragByParticleVelocity;

Description

Adjust the amount of drag this module applies to particles, based on their speeds.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public float hSliderValueDrag = 1.0f; public bool hToggleUseSize = false; public bool hToggleUseVelocity = false;

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

var limitVelocityOverLifetime = ps.limitVelocityOverLifetime; limitVelocityOverLifetime.enabled = true;

var main = ps.main; main.startSize = new ParticleSystem.MinMaxCurve(0.1f, 1.5f); main.startSpeed = new ParticleSystem.MinMaxCurve(0.5f, 5.0f); }

void Update() { var limitVelocityOverLifetime = ps.limitVelocityOverLifetime; limitVelocityOverLifetime.dragMultiplier = hSliderValueDrag; limitVelocityOverLifetime.multiplyDragByParticleSize = hToggleUseSize; limitVelocityOverLifetime.multiplyDragByParticleVelocity = hToggleUseVelocity; }

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

hSliderValueDrag = GUI.HorizontalSlider(new Rect(135, 45, 100, 30), hSliderValueDrag, 0.0f, 3.0f); hToggleUseSize = GUI.Toggle(new Rect(25, 85, 200, 30), hToggleUseSize, "Multiply by Size"); hToggleUseVelocity = GUI.Toggle(new Rect(25, 125, 200, 30), hToggleUseVelocity, "Multiply by Velocity"); } }
