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

//Created by Platur

public class Flashlight : MonoBehaviour {

//Our Lightsource
public Light flashlightSource;
//Our state
private bool state;

// Use this for initialization
void Start () {
    //We get the Light of the Gameobject where the script are
    flashlightSource = this.GetComponent<Light>();

    //We change our state to the state of the Light Compnonent
    state = flashlightSource.enabled;
    
}

// Update is called once per frame
void Update () {

    //If we Press Keycode F we change the state
    if (Input.GetKeyUp(KeyCode.F)) {
        //How is our state?
        if (state == true)
        {
            //Its on so we disable the Light
            flashlightSource.enabled = false;
            state = false;
        }
        else
        {
            //Its off so we enable the Light
            flashlightSource.enabled = true;
            state = true;
        }
    }
}

}
