public void SetPlane (int index, Transform transform);

Parameters

indexSpecifies which plane to set.
transformThe plane to set.

Description

Set a collision plane to be used with this particle system.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { private ParticleSystem ps;

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

var collision = ps.collision; collision.enabled = true; collision.type = ParticleSystemCollisionType.Planes; collision.mode = ParticleSystemCollisionMode.Collision3D;

var collider = GameObject.CreatePrimitive(PrimitiveType.Plane); collider.transform.parent = ps.transform; collider.transform.localPosition = new Vector3(0.0f, 0.0f, 5.0f); collider.transform.localScale = new Vector3(20.0f, 20.0f, 20.0f); collider.transform.localRotation = Quaternion.Euler(new Vector3(-90.0f, 0.0f, 0.0f));

collision.SetPlane(0, collider.transform); } }
