Flashlight error

Unity Engine
1

Hello guys!I’m making a horror game and i’m messing with a realistic flashlight.I tried to find a good flashlight + battery life indicator,i searched for an hour and the most functional was from this vid:

And i inserted the code and followed EVERYTHING,here is it:

#pragma strict

var flashlightLightSource : Light;
var lightOn : boolean = true;
var lightDrain : float = 0.1;
private static var batteryLife : float = 0.0;
var maxBatteryLife : float = 2.0;

private static var batteryPower : float = 1;

var barDisplay : float = 0;
var pos : Vector2 = new Vector2(20,40);
var size : Vector2 = new Vector2(60,20);
var progressBarEmpty : Texture2D;
var progressBarFull : Texture2D;

var soundTurnOn : AudioClip;
var soundTurnOff : AudioClip;


function Start()
{
    batteryLife = maxBatteryLife;
    flashlightLightSource = GetComponent(Light);
}


static function AlterEnergy (amount : int)
{
    batteryLife = Mathf.Clamp(batteryLife+batteryPower, 0, 100);

}



function Update()
{

//BATTERY LIFE BRIGHTNESS//////////
    if(lightOn && batteryLife >= 0)
    {
        batteryLife -= Time.deltaTime * lightDrain;
    }
        if(lightOn && batteryLife <= 0.4)
    {
        flashlightLightSource.light.intensity = 5;
    }
        if(lightOn && batteryLife <= 0.3)
    {
        flashlightLightSource.light.intensity = 4;
    }
    if(lightOn && batteryLife <= 0.2)
    {
        flashlightLightSource.light.intensity = 3;
    }
        if(lightOn && batteryLife <= 0.1)
    {
        flashlightLightSource.light.intensity = 2;
    }
            if(lightOn && batteryLife <= 0)
    {
        flashlightLightSource.light.intensity = 0;
    }
   

   
    barDisplay = batteryLife;
   
    if(batteryLife <= 0)
    {
        batteryLife = 0;
        lightOn = false;
    }
   
    if(Input.GetKeyUp(KeyCode.F))
    {
        toggleFlashlight();
        toggleFlashlightSFX();
       
        if(lightOn)
        {
            lightOn = false;
        }
        else if (!lightOn && batteryLife >= 0)
        {
            lightOn = true;
        }
    }
}
   
    /////// PIC  ///////////
function OnGUI()
{
    // draw the background:
    GUI.BeginGroup (new Rect (pos.x, pos.y, size.x, size.y));

        // draw the filled-in part:

        audio.clip = soundTurnOff;
    }
    audio.Play();
   
}

    @script RequireComponent(AudioSource)

////////You are welcome/////////

But for some reason,when i turn off the flashlight,to preserve my battery,the error was that when i turned my flashlight off unity crashed,but i just changed the flashlight location from main camera to firstpersoncontroller.But now,it does turn off,and work properly except that THIS happens in my console:

MissingComponentException: There is no ‘Light’ attached to the “First Person Controller” game object, but a script is trying to access it.
You probably need to add a Light to the game object “First Person Controller”. Or your script needs to check if the component is attached before using it.
Flashy.toggleFlashlight () (at Assets/Standard Assets/Flashy.js:112)
Flashy.Update () (at Assets/Standard Assets/Flashy.js:77)

Anyone know the issue?,I’m using unity 4.6.2 because unity 5 glitched the render setting so i cannot make it night or foggy,which is the version ryandome used,and also,my flashlight keeps on after the error,yet it still displays the code.

Only issue I can think of is repeated script in your hierarchy…
In the First Person Controller game object (where you should have your Flash.js), do you have a Light? That’s the reason why you get the error! In line 24 you do a GetComponent, if you dont have a Light Component in the same gameobject as the script, it’ll be a null variable and so the error you see in console!

You said that the light goes on/off, but I’m pretty sure that’s because you have another Flash.js as component of the gameobject where you do have the Light component now!

Thanks!I’ll try

It works!!! I just deleted the script from the firstpersoncontroller and put it directly on my flashlight,thank you.

Actually,my flashlight only looks forward,not up or down,but anyways
