For each string in Array

Question

Just as the name says, I want that for each certain name in an array a value is added to a int.

For example: if there are 3 strings of the same name in the array, then 3 times 50 will be added to the value.

This is my script I have now:

var lootList = new Array();
var interaction : Texture;
var interact = false;
var position : Rect;
var ching : AudioClip;
var lootPrice = 0;

function Update()
{
    print(lootList);

    if ("chalice" in lootList){
        lootPrice += 50;
    }
}

function Start()
{
    position = Rect( ( Screen.width - interaction.width ) /2, ( Screen.height - interaction.height ) /2, interaction.width, interaction.height );
}

function OnTriggerStay(col : Collider)
{   
    if(col.gameObject.tag == "loot")
    {
        interact = true;

        if(Input.GetKeyDown("e"))
        {
            if(col.gameObject.name == "chalice")
            {
                Destroy(col.gameObject);
                print("chaliceObtained");
                audio.clip = ching;
                audio.pitch = Random.Range(0.8,1.2);
                audio.Play();
                interact = false;
                lootList.Add("chalice");
            }

            if(col.gameObject.name == "moneyPouch")
            {
                Destroy(col.gameObject);
                print("moneyPouchObtained");
                audio.clip = ching;
                audio.pitch = Random.Range(0.8,1.2);
                audio.Play();
                interact = false;
                lootList.Add("moneyPouch");
            }

            if(col.gameObject.name == "ring")
            {
                Destroy(col.gameObject);
                print("ringObtained");
                audio.clip = ching;
                audio.pitch = Random.Range(0.8,1.2);
                audio.Play();
                interact = false;
                lootList.Add("ring");
            }

            if(col.gameObject.name == "goldCoins")
            {
                Destroy(col.gameObject);
                print("coldCoinsObtained");
                audio.clip = ching;
                audio.pitch = Random.Range(0.8,1.2);
                audio.Play();
                interact = false;
                lootList.Add("goldCoins");
            }

            if(col.gameObject.name == "plate")
            {
                Destroy(col.gameObject);
                print("plateObtained");
                audio.clip = ching;
                audio.pitch = Random.Range(0.8,1.2);
                audio.Play();
                interact = false;
                lootList.Add("plate");
            }
        }
    }
}

function OnTriggerExit(col : Collider)
{   
    if(col.gameObject.tag == "pouch")
    {
        interact = false;
    }
}

function OnGUI()
{
    if(interact == true)
    {
        GUI.DrawTexture(position, interaction);
        GUI.color.a = 1;
    }
}

It's for a game I'm making where you can steal items for extra score points.

I've tried using the for(i = 0; i < variable.Length; i++) but that didn't seem to work.

The only thing I can think of now is using booleans to add it once. But that isn't memory friendly.

Help is appreciated and thanks in advance!

And where should the loop be? We don't know how your script is supposed to work. Is all the code necessary for the problem? — Felix Kling

You could use the standard .forEach(callback) method:

lootList.forEach(function(value, index, array)
{
    if (value === "chalice") { lootPrice += 50; }
});

If you don't have that method, you could implement it like this:

if (!Array.prototype.forEach) {
    Array.prototype.forEach = function (callback) {
        for(var i = 0; i < this.length; i++) { callback(this[i], i, this); }
    }
}
