Flashlight Code

Below is the code for the flashlight, it does the following:

• Upon spawn the player will not have a flashlight
• When a flashlight is collected it will be off until it is turned on
• if the player has a torch and it is on reduce the battery life
• if the right bumper (xbox controller) is pressed the light will turn on if it not
• likewise if the right bumper button is pressed when the flashlight is on, it will turn off
• when the flashlight is collected the HUD for the battery life will be set to 100
• if the battery life is less than or equal to 0 set it to zero and turn the flashlight off
• if the battery life is 0 and the HUD shows that batteries are held reduce the battery count by one and add 100 to the battery life (for the flashlight)

using UnityEngine;

using System.Collections;

public class Flashlight : MonoBehaviour {

public static float BatteryLife = 100;

public Light Torch;

public float BatteryReductionSpeed = 3.0f;

void Awake()

{

Torch.enabled = false;

}

void Update()

{

if (Torch.enabled) 

{

BatteryLife = BatteryLife - (BatteryReductionSpeed * Time.deltaTime);

}

if (Input.GetButtonDown ("RightBumper") && HUD.HasFlashlight && !Torch.enabled) 

{

if (BatteryLife <= 0 && HUD.BatteryCount>0)

{

HUD.BatteryCount--;

BatteryLife = 100;

}

Torch.enabled = true;

} 

else if (Input.GetButtonDown ("RightBumper") && HUD.HasFlashlight && Torch.enabled)

{

Torch.enabled = false;

}

if (BatteryLife <= 0) 

{

BatteryLife = 0;

Torch.enabled = false;

}

}

}
