Position of particlesystem isn't attached to object - unity3d

Question

I added a particle system to my unity project. But I can't make it attach to a certain game object or tag. How can I make a Particle System sit on the center of a cube, while it's getting played once if the player triggers with this cube?
Code used for the trigger to work:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Collision_Player_grower : MonoBehaviour
{
public GameObject Player_grower;
public ParticleSystem CollisionGrower;
// Start is called before the first frame update
void Start()
{
times_player_grower = 0;
CollisionGrower.transform.position = Player_grower.transform.position;
}
// Update is called once per frame
void OnTriggerEnter(Collider collision)
{
if (collision.gameObject.tag == "Player")
{
print("we hit an playergrower");
CollisionGrower.Play();
Destroy(Player_grower);
}
}
}
Note: It does work if I manually place the particle system in the heart of the cube, but I assume this can be done in an easier way.

Answer 1

From what I understand, you want the position of the particle system to be in the center of another object.
1)
You could do that simply by attaching a particle system game object as a child of the cube you were talking about.
2)
You could do this with code instead. In case you want the particle system to do something extra, you could just adjust the code.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Collision_Player_grower : MonoBehaviour
{
public GameObject ParticleSystemObject;
public GameObject Cube;
public GameObject Player_grower;
public ParticleSystem CollisionGrower;
// Start is called before the first frame update
void Start()
{
times_player_grower = 0;
CollisionGrower.transform.position = Player_grower.transform.position;
}
// Update is called once per frame
void Update()
{
ParticleSystemObject.transform.position = Cube.transform.position;
}
void OnTriggerEnter(Collider collision)
{
if (collision.gameObject.tag == "Player")
{
print("we hit an playergrower");
CollisionGrower.Play();
Destroy(Player_grower);
}
}
}
I don’t fully understand what the rest of the variables are for, and what they are, so I may have done some un-needed things.
First, I added two GameObject variables. One of them is the cube object you want the particle system to go to, and the other is the particle system as a game object. I set the position of the particle system to the position of the cube.
Important: if you have this script attached to the cube, remove the Cube variable.
Instead of using
... = Cube.transform.position;
Use
... = transform.position;
