var light1:Light;
var light2:Light;
var lightTimer : float = 0.0;
var lightBattery : float = 8.0;

public var lightOn : boolean = false;

function Update () {

if (Input.GetButtonDown (“Fire1”))

{
audio.Play();
lightOn = !lightOn;

light1.enabled = lightOn;
light2.enabled = lightOn;

}
}

try this but
Note: you must have the audio source added to it for it to work

Here’s something I wrote yesterday, its much simpler, its C#, and doesn’t use the update function. Obviously the less code being called every single frame, the better, right?

using UnityEngine;
using System.Collections;

public class FlashLight : MonoBehaviour 
{
	public Light light1;  

	void Start()
		{
				light1.enabled = false;
		}
	
	public void ToggleFlashLight () 
		{

		if (light1.enabled == true) 
				{
						light1.enabled = false;
				}
		else
				{
						light1.enabled = true;
				}
		}
}

Here is a simple way to turn a light on and off by Clicking

 using UnityEngine;
 using System.Collections;
 
 public class Flashlight : MonoBehaviour {
 
     public Light light;    //assign gameobject with light component attached
 
     void Update () {
         if (Input.GetMouseButtonDown (0)) {      //Left mouse button
             light.enabled = !light.enabled;      //changes light on/off
         }
     }
 }

  • Make sure you add the script to GameObject with the light component.

  • Then assign the same GameObject to ‘light’.
