public bool allowRoll { get; set; }
Remarks
Allows billboards to roll with the Camera. It is often useful to disable this option when using VR, to give particles a more believable grounding in the world.
Examples
using UnityEngine;using System.Collections;[RequireComponent(typeof(ParticleSystem))]public class ExampleClass : MonoBehaviour{ private ParticleSystemRenderer psr; public bool allowRoll = true; void Start() { psr = GetComponent<ParticleSystemRenderer>(); psr.material = new Material(Shader.Find("Sprites/Default")); } void Update() { var psr = GetComponent<ParticleSystemRenderer>(); psr.allowRoll = allowRoll; Camera.main.transform.rotation = Quaternion.Euler(0.0f, 0.0f, Mathf.Sin(Time.time * 0.2f) * 90.0f); } void OnGUI() { allowRoll = GUI.Toggle(new Rect(25, 45, 200, 30), allowRoll, "Allow Roll"); }}
