Error when accessing variables from another script: NullReferenceException: Object Reference not set to an instance of an object..
Hello people. I have 2 variables in my Flashlight script (which is located on a spotlight on the maincamera): batteryLife and maxBatteryLife. I wanted a reload type of thingy because the flashlight shuts off when batteryLife <= 0.
So i made a new script (located on the first person controller) and tried calling the two variables from Flashlight, but i get this Error: NullReferenceException: Object Reference not set to an instance of an object PickUpBatteries.ReloadCamera()
#pragma strict
function Update ()
{
if (Input.GetKeyDown("r"))
{
ReloadCamera();
}
}
function ReloadCamera ()
{
GetComponent(Flashlight).batteryLife = GetComponent(Flashlight).maxBatteryLife;
}
Can you guys help me tweak it and thell me what im doing wrong?
Your code is assuming that the 'Flashlight' component is on the same game object as the above script, but from your description it is not. The typical solution:
#pragma strict
private var fl : Flashlight;
function Start()
{
fl = GameObject.Find("Name of Flashlight Object").GetComponent(Flashlight);
}
function Update ()
{
if (Input.GetKeyDown("r"))
{
ReloadCamera();
}
}
function ReloadCamera ()
{
fl.batteryLife = fl.maxBatteryLife;
}

Wow thanks! It does work now and you totally explained how to syntax it properly. Thanks a BUNCH!!!
