Trying to reduce the yellow warnings in project

Unity Engine
1

Hi
So i have a couple hundred yellow warning from assets iv downloaded mostly particle systems so trying to cut down on them but can’t figure out why this code gives the following warning

Assets/Standard Assets/Effects/ImageEffects/FT_Infinity_lite/Scenes/Data/Scripts/SpawnProjectile.cs(50,15): warning CS0219: The variable `projectile’ is assigned but its value is never used

Error points to the last line how can i rewrite it to have the yellow error msg go bye bye.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class SpawnProjectile : MonoBehaviour {

    public Camera mainCam;
    public Transform spawn;
    public GameObject[] effects;
    private int count = 0;
    public Text text;

    // Use this for initialization
    void Start () {
        text.text = effects [count].name;
    }
   
    // Update is called once per frame
    void Update () {
        //Player Look at Mouse Position
        Ray ray = mainCam.ScreenPointToRay(Input.mousePosition);
        Plane ground = new Plane (Vector3.up, Vector3.zero);
        float rayDistance;
        if (ground.Raycast (ray, out rayDistance)) {
            Vector3 point = ray.GetPoint (rayDistance);
            Vector3 correctPoint = new Vector3 (point.x, transform.position.y, point.z);
            transform.LookAt (correctPoint);
        }
        if (Input.GetKeyDown (KeyCode.RightArrow)) {
            if (count >= effects.Length -1) {
                count = 0;
            } else {
                count++;
            }
            text.text = effects [count].name;
        }

        if (Input.GetKeyDown (KeyCode.LeftArrow)) {
            if (count <= 0) {
                count = effects.Length -1;
            } else {
                count--;
            }
            text.text = effects [count].name;
        }       

        //Shoot
        if(Input.GetMouseButtonDown(0)){
            GameObject projectile = Instantiate (effects[count], spawn.position, spawn.rotation);
        }
    }

Thx

Error is pretty clear: you assign the value but don’t do anything with it, making the assignment pointless.

GameObject projectile = Instantiate (effects[count], spawn.position, spawn.rotation);

can become

Instantiate (effects[count], spawn.position, spawn.rotation);
