Detecting collision between particle and player.

Question

Hello,

I am trying to make my game detect the collision between pepper gas smoke particles and my player, and if such collision occurs, apply some damage to the player. But as I have spent my last 2 days, although I can see the collision happening in the game scene, the collision has never been detected. I use Shuriken particle system. I checked the collision in the inspector, and both the player and the particle system has the RigidBody physic.

My code goes as:

 #pragma strict
 
 var P : GameObject;
 var HitByGaz : boolean = false;
 
 function OnParticleCollision (other : GameObject) {
 
             Debug.Log ("Pepper gas!");
 
             
             if(other.tag == "Player") {
             
             P.gameObject.GetComponent(PlayerHealth).currentHealth -= 1;
             HitByGaz = true;
             HitByGaz = false;
         
         
     }
 }

I can't even get the log working. Thanks for helping out.

 #pragma strict
 var player : GameObject;
    
     function OnParticleCollision (other : GameObject) {
         var body : Rigidbody = other.rigidbody;
         if (body) {
             Debug.Log("player");
         }
     }

works for me... if not working set your collision quality to high.

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

public class Example : MonoBehaviour

{

 public ParticleSystem.Particle[] ParticleList;

 private ParticleSystem m_particleSystem;

 private GameObject character;

 int Score = 0;

 void Start()
 {
     character = GameObject.FindGameObjectWithTag ("Iz");

     m_particleSystem = GetComponent<ParticleSystem> ();
 }

 void LateUpdate ()
 {
     //This list will be used to store each particle that is alive 

     ParticleList = new ParticleSystem.Particle[m_particleSystem.particleCount];

     //storing particles into a list
     m_particleSystem.GetParticles (ParticleList);

     // Change only the particles that are alive
     for (int z = 0; z < GetComponent<ParticleSystem> ().particleCount; z++) 
     {    
         //getting the position of the player and the particle
         Vector3 dis = ParticleList [z].position - character.transform.position;

         //if it is near
         if(dis.magnitude <= 5)
         {
             //destroy the particle
             ParticleList [z].lifetime = 0;
             //add score
             Score++;
         }
     }

     // Apply the particle changes to the particle system
     m_particleSystem.SetParticles (ParticleList, m_particleSystem.particleCount);
 }

}
