How can i add a key toggle to tuen on/off spotlight ?

In my unity project i have a firstpersoncharacter under it connect to it a spotlight.
Then i clicked in the menu on Assests > Open C# Project
Then i deagged the c# icon to the spotlight.
Then double click on the c# script icon and it opend the script code:

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

    // Use this for initialization
    void Start () {
   
    }
   
    // Update is called once per frame
    void Update () {
   
        if (Input.GetKeyDown(KeyCode.F)
            {
                if (light.name)
                {
                }
            }
    }
}

But i have some problems.
First i’m getting error on the { of the first input under the if (Input.GetKeyDown(KeyCode.F)
This { under it i see red small line the error is: Parse Error: Unexpected symbol “{”

Second problem is when i select in the inner if light i see a line on the light variable like this --------
And it says: Thel ight attached to this gameobject (null if there is none attached)

I tried to make if (light.
But there is no enable property.

How should i fix all this ?

Please format your code with proper code tags.

I fixed the error with the symbol “{” i forgot to add another ) in the if. But still i don’t understand the problem with the light var.

you seem to be missing alot of the basic concepts… I’d really suggest you start with some scripting tutorials
