ParticleSystem.CollisionModule.type

Description

The type of particle collision to perform.

Here is an example of plane collsiion:

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);
	}
}
