Hey guys I am completely new to scripting and I am currently trying to learn c# and java through YouTube
I’m trying to make a flashlight and battery system using this tutorial I found online
After the battery has completely runs out, I pick up a new battery but when I try to turn the flashlight bak on, it won’t turn on! The intensity of the light stays at 0!
It’s getting frustrating and I have tried the different scripts in the comments but they don’t work! Can anyone edit the script for me so the flashlight will turn back on?
hey, generally it’s better to just paste the code into the forums using the tags, saves people having to download the file, open the file, etc. before they can help.
//FlashLight.js

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.GetComponent.<Light>().intensity = 5;
}
if(lightOn && batteryLife <= 0.3)
{

AudioSource.PlayClipAtPoint(batterySound, transform.position);

Destroy(gameObject);

}
}
}
}
also if you’re new to all this you’re probably better off working with the new UI rather than learning the legacy system:
OnGUI was “replaced” by the canvas system in Unity4.6+, there are lots of older tutorials which won’t cover it, something to be aware of.
