Score/point counter system

Questions & Answers
1

I have scattered targets placed throughout my sandbox fps-like game. These targets each have the following code equipped:

var hitPoints = 100.0;
var detonationDelay = 0.0;
var explosion : Transform;
var deadReplacement : Rigidbody;
function ApplyDamage (damage : float)
{
// We already have less than 0 hitpoints, maybe we got killed already?
if (hitPoints <= 0.0)
return;
hitPoints -= damage;
if (hitPoints <= 0.0)
{
// Start emitting particles
var emitter : ParticleEmitter = GetComponentInChildren(ParticleEmitter);
if (emitter)
emitter.emit = true;
Invoke("DelayedDetonate", detonationDelay);
}
}

function DelayedDetonate ()
{
BroadcastMessage ("Detonate");
}

function Detonate ()
{
// Destroy ourselves
Destroy(gameObject);
// Create the explosion
if (explosion)
Instantiate (explosion, transform.position, transform.rotation);

// If we have a dead barrel then replace ourselves with it!
if (deadReplacement)
{
var dead : Rigidbody = Instantiate(deadReplacement, transform.position,
transform.rotation);
// For better effect we assign the same velocity to the exploded barrel
dead.rigidbody.velocity = rigidbody.velocity;
dead.angularVelocity = rigidbody.angularVelocity;
}

// If there is a particle emitter stop emitting and detach so it doesnt get destroyed
// right away
var emitter : ParticleEmitter = GetComponentInChildren(ParticleEmitter);
if (emitter)
{
emitter.emit = false;
emitter.transform.parent = null;
}
}
// We require the barrel to be a rigidbody, so that it can do nice physics
@script RequireComponent (Rigidbody)

For each target destroyed I would like a set amount of points to be added to a counter/score system...

Any suggestions to how I can execute this efficiently? Also how would I associate the concept to creation of new GUIskin??

Thanks.

PointManager: (script 1)

attatch this script to a guiText

static var points = 0.0; // A static var can be acessed form other scripts. 

function Update ()
{
//assuming that you want the score on a guiText.

guiText.text = "" + points;
}

//New script:

var pointsToAdd = 10; // You will add 10 points for each kill.

function Update ()
{
//When the enemy is dead.
//we add points to the script above using the name of the script(PointManager) 
//and the variable name(points)
PointManager.points += pointsToAdd;
}
