Answer 1

Visual Effects API

https://docs.unity3d.com/2018.3/Documentation/ScriptReference/Experimental.VFX.VisualEffect.html

Stop Send a stop event to all Spawn systems.

Play Sends a stop event to all Spawn systems. If VisualEffect.resetSeedOnPlay is true, this methods recomputes a new random seed for the random value generator and resets internal total time to zero.

C# API

https://docs.unity3d.com/Packages/[email protected]/manual/index.html

using UnityEngine;
using UnityEngine.Experimental.VFX;

public class VFXTest : MonoBehaviour
{
    public bool IsPlaying = true;
    void Update()
    {
        if(Input.GetKeyDown(KeyCode.Space)){
        IsPlaying = !IsPlaying;
        }

        if(IsPlaying){
        GetComponent<VisualEffect>().Play();
        }else{
        GetComponent<VisualEffect>().Stop();
        }
    }
}
