2. Start off by declaring a variable to reference our WeaponFlashlight.

var WeaponFlashlight Flashlight;

3. We also need to add some functionality in our PostBeginPlay() function:

simulated event PostBeginPlay()

{

Super.PostBeginPlay();

'Log("================");

'Log("Tutorial Pawn up");

//***** Used for the flashlight *****//

// Spawns the light on the player, setting self as owner

Flashlight = Spawn(class'WeaponFlashlight', self);

// Sets the lights base on at the player

Flashlight.SetBase(self);

// Light is off by default

Flashlight.LightComponent.SetEnabled(false);

// Starts at 75% brightness

Flashlight.LightComponent.SetLightProperties(0.75);

}

We're doing a few things here. First, we're spawning our WeaponFlashlight and

setting our pawn as the owner. Afterwards, we're attaching the light to our pawn,

keeping it toggled to off by default, and dropping the brightness down to 75 percent.

4. The flashlight is attached to our pawn, but we need it to rotate when our pawn
   rotates, so let's do that now:
   /****
   
   
   • Forces the flashlight to use our pawn's rotation
     ****/
     event UpdateEyeHeight( float DeltaTime )
     {
     Super.UpdateEyeHeight(DeltaTime);
   
   
   
   

// Flaslight will use our controller's rotation

Flashlight.SetRotation(Controller.Rotation);

/* Offset the light slightly, so that it looks as

though it is coming from our pawn's eyes/helmet */

Flashlight.SetRelativeLocation

(Controller.RelativeLocation + vect(20, 0, 25));

}
