Start rotation multiplier around the Y axis.
This method is more efficient than accessing the whole 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 main = ps.main; main.startRotation3D = true;
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.startRotationYMultiplier = hSliderValue; }
void OnGUI() { hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 0.0F, 360.0F * Mathf.Deg2Rad); } }
