public float zMultiplier;

Description

Rotation multiplier around the z-axis.

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

using UnityEngine;
using System.Collections;

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

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

var rotationOverLifetime = ps.rotationOverLifetime; rotationOverLifetime.enabled = true;

AnimationCurve curve = new AnimationCurve(); curve.AddKey(0.0f, 0.0f); curve.AddKey(1.0f, 1.0f);

rotationOverLifetime.zMultiplier = (Mathf.PI * 2.0f);

var psr = GetComponent<ParticleSystemRenderer>(); psr.material = new Material(Shader.Find("Sprites/Default")); // this material renders a square billboard, so we can see the rotation }

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

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