I’m trying to make a shooter game, and i’m trying to edit the code for the bullet impact effect to make it disappear. but it comes up with this error.
error CS0266: Cannot implicitly convert type UnityEngine.Object to UnityEngine.GameObject. An explicit conversion exists (are you missing a cast?)

GameObject impactGO = Instantiate(impactEffect, hit.point, Quaternion.LookRotation(hit.normal));
Destroy (impactGO, 2f);

using UnityEngine;

2

GameObject impactGO = Instantiate(impactEffect, hit.point, Quaternion.LookRotation(hit.normal)) as GameObject;

OR

GameObject impactGO = (GameObject) Instantiate(impactEffect, hit.point, Quaternion.LookRotation(hit.normal));
