How to make particles not disappear when called a second time
I'm trying to make a nice particle system that stays for a while, but the thing is, the particles disappear instantly once I call the particles again. How would I make the particles not disappear upon calling it again while not having to deal with prefabs and instantiation? This is my code script for moving the character:

script for moving particles to the player but not stick to it: using System.Collections; using System.Collections.Generic; using UnityEngine;
public class PartMoove : MonoBehaviour
{
public Transform targetpart;
public bool rotato;
public float offsety;
public void Move()
{
transform.position = new Vector3(targetpart.position.x,targetpart.position.y-offsety,targetpart.position.z);
if(rotato == true)
{
if(targetpart.eulerAngles.y == 0f)
{
transform.eulerAngles = new Vector3(0f,-90f,0f);
}
else if(targetpart.eulerAngles.y == 180)
{
transform.eulerAngles = new Vector3(0f,-270f,0f);
}
}
}
}
Also, as a side note, does anyone know how to add friction to the particle collisions?
