How to make a flashlight toggleable in C#?

You could use a input function. Im just assuming your "flashlight" is actually a directional light in Unity.

 JAVASCRIPT:
 
 var flashlight : Light;
 
 function Update () {
 if(input.GetKeyDown(KeyCode.F) && flashlight.enabled == false){
 flashlight.enabled = true;
 }else if(input.GetKeyDown(KeyCode.F) && flashlight.enabled == true){
 flashlight.enabled = false;
 }
 }
 
 C#:
 
 public Light flashlight;
 
 void Update () {
 if(input.GetKeyDown(KeyCode.F) && flashlight.enabled == false){
 flashlight.enabled = true;
 }else if(input.GetKeyDown(KeyCode.F) && flashlight.enabled == true){
 flashlight.enabled = false;
 }
 }

That should work for you.

Here's a flashlight script I use:

using UnityEngine; using System.Collections;

public class Flashlight : MonoBehaviour {

 //Flashlight Object
 public Light flashlight;

 //Flashlight power variables
 public float power = 100.0f;
 private float maxPower = 100.0f;
 private float minPower = 0.0f;

 //Battery charge variable
 private float batteryCharge = 100.0f;

 //Number of batteries currently possesed by the player
 public int batteryCount = 3;

 //Power Drain controls how fast the battery life decreases
 public float powerDrain = 1.0f;

 //Boolean that tells whether or not the flashlight is able to be used based off of current power
 private bool usable = true;

 void Start ()
 {

 }

 void Update () 
 {
     //If the F key is pressed and the power is greater than zero, then the flashlight will toggle between on and off
     if (Input.GetKeyDown (KeyCode.F) && usable) 
     {
         flashlight.enabled = !flashlight.enabled;
     }

     //While the flashlight is off, the power will drain
     if (flashlight.enabled) 
     {
         power -= Time.deltaTime * powerDrain;
     }

     //This is to ensure that the power will never go over 100
     if (power > maxPower) 
     {
         power = maxPower;
     }

     //This is to disable to flashlight and make sure it can't be used until the player uses a battery to recharge the flashlight
     if (power < minPower) 
     {
         power = minPower;
         flashlight.enabled = false;
         usable = false;
     }

     //After you replace the batteries, it allows you to use the flashlight again
     if (power > minPower)
     {
         usable = true;
     }

     //This says that if the player has at least one battery, and if they press R, then the flashlight will be fully charged
     if (Input.GetKeyDown (KeyCode.R) && batteryCount > 0)
     {
         power += batteryCharge;
         batteryCount -= 1;
     }
 }

}

And here's the battery script I use:

using UnityEngine; using System.Collections;

public class Battery : MonoBehaviour {

 //Battery game object
 public GameObject battery; 

 //Boolean that tells if the player is in the battery's collider
 private bool trig = false;

 //When player enters the collider, player will be able to collect the battery
 void OnTriggerEnter ()
 {
     
         trig = true;

 }

 //When player exits the collider, player will be not able to collect the battery
 void OnTriggerExit ()
 {

         trig = false;

 }
     
 void Start () 
 {
     trig = false;
 }
 

 void Update () 
 {
     //When the player enters the trigger and presses the E key, they will recieve a new battery and the battery they collected will be removed from the scene
     if (trig && Input.GetKeyDown (KeyCode.E)) 
     {
         //Finds and acesses the flashlight script
         Flashlight flashlight = GameObject.FindGameObjectWithTag("Flashlight").gameObject.GetComponent<Flashlight> ();

         //Adds a battery
         flashlight.batteryCount += 1;

         //Removes the battery collected from the scene
         Destroy (battery);
     }
 }

}

An important thing to note: You'll need to tag your flashlight as "Flashlight" so that the battery script can access the batteryCount variable.

@blackuethel 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'.
