CS0266 C# Cannot implicitly convert type 'UnityEngine.Object' to ''. An explicit conversion exists (are you missing a cast?)

Question

I have a compiler error where the compiler cannot convert type "UnityEngine.Object to Gun. I don't think that these are different file types, but anyway, here's my code. I've been stumped on this and I'm no pro on C# yet, so forgive me if it's a n00b mistake. Idk how to use the code insert on this, it confuses me, so here's a printscreen.

using UnityEngine;
using System.Collections;

public class GunController : MonoBehaviour {

    public Transform WeaponHold;
    public Gun startingGun;
    Gun equippedGun;

    void Start()
    {
        if (startingGun != null)
        {
            EquipGun(startingGun);
        }
    }

    public void EquipGun(Gun gunToEquip)
    {
        if(equippedGun != null)
        {
            Destroy(equippedGun.gameObject);
        }
        equippedGun = Instantiate(gunToEquip, WeaponHold.position,WeaponHold.rotation);
        equippedGun.transform.parent = WeaponHold;
    }
}

Answer 1

TheInstantiate method returns an object , which you can cast to the necessary type.

Cast it to a Gun and it should stop complaining:

equippedGun = (Gun)Instantiate(gunToEquip, WeaponHold.position, WeaponHold.rotation);

Answer 2

Make sure your class inherits from MonoBehaviour.

public class MyClass : MonoBehaviour{

}
