Allow billboard particles to roll around their Z axis.
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.
using UnityEngine; using System.Collections;
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"); } }
