Search for Item in Inventory (Generic List) (Javascript)

[Fraeger]

Hello!

I am relatively new to scripting so please forgive me if my question is astupid

I want to search for a specific Item in my Intentory. My inventory Code looks like this:+

Inventory.js

static var inventory: List. = new List. ();

My items look like this:

#Itemclass.js

public class ItemClass {

	var name : 	String;
	var icon :	Texture2D;
	var description: String;
	var ID: int;

}

Now, if I add some Items to my Inventory, how can i remove specific ones?
I thought of finding the Index and then using RemoveAt, however I cannot find a way to find out the Indexnumber. I used IndexOf:

var MoneyIndex: int = Inventory.inventory.IndexOf (“Money”);

However, that gives me an Error. It also makes sense since only the name variable in the Itemclass is called Money and not the Itemclass itself.

Any Ideas anyone?

I will assume your code looked like this:

static var inventory: List.< ItemClass > = new List.< ItemClass > ();

instead of

static var inventory: List. = new List. ();

IndexOf won’t work, since IndexOf would be trying to find the index of a given instance already in a list (an instance of a complete ItemClass object). You don’t have an instance to test with, you only want to remove objects that have a property set to “Money”, I guess.

One way to do it is with delegates and use RemoveAll. You can also use for loops, or consider switching to associative structures, such as Dictionary.< TKey, TValue >.

#pragma strict

import System.Collections.Generic;

public class ItemClassExample extends MonoBehaviour 
{
    var inventory : List.< ItemClass > = new List.< ItemClass > ();
    
    function Start() {
        inventory.RemoveAll(function(item) item.name == "Money");
    }
}

public class ItemClass 
{
    var name : String;
    var icon : Texture2D;
    var description : String;
    var ID : int;
}

The Mono Upgrade Details contains some examples that show delegates.
