Issue with List.Contains Method.

Questions & Answers
1

Hello all, this is my first time here. Usually I am able to solve my code issues but this one is eluding me.

I have a Generic List which makes up my Player Inventory, this List contains Item Classes; which in turn have have strings I wish to access, ie Item Names.

I am having trouble accessing strings inside the classes using List.Contains.

My Item Class is as follows:

#pragma strict

public class Item_Class
{
	public var Item_Name:String;
	public var Item_Desc:String;
	public var Item_Type:String;
	public var Item_Size:String;
	public var Item_Icon:Texture2D;
	public var Item_Prefab:String;	
}

I thought that I would be able to access the Item_Name string by doing something along the lines of:

if (_myinventory.Contains(Item_Class.Item_Name("")))
{
    // Do something.
}

I am having no luck, help would be much appreciated. Thanks.

Instead of a List<>, try using a Dictionary, where you assign Values to Keys, then you could search for a named Key. It wont work if all the Values aren’t string though…

I got around this a little to suit my needs by doing the following:

function Update()
{
	// Quickbar 1.
	if (Input.GetKeyDown("1"))
	{
		_1KeyRecentlyPressed = true;
		
		for(var a = 0; a < _inventory._playerInventory.Count; a++)
		{
			if (_inventory._playerInventory[a].Item_Type == "StimPack")
			{
				_guiStimPackIndex = a;
			}	
		}
	}
	
	if (Input.GetKeyUp("1"))
	{
		if (_1KeyRecentlyPressed && _guiStimPackCount != 0)
		{
			_playerControllerScript.UseItem("StimPack");
			_inventory._playerInventory.RemoveAt(_guiStimPackIndex);
			
			CheckQuickbarQuota();
			
			_1KeyRecentlyPressed = false;
		}
	}
}

function CheckQuickbarQuota()
{
	_guiStimPackCount = 0;
	_guiMedicalKitCount = 0;
	_guiReconDroneCount = 0;

	for(var e = 0; e < _inventory._playerInventory.Count; e++)
	{
		if (_inventory._playerInventory[e].Item_Type == "StimPack")
		{
			_guiStimPackCount++;
		}
				
		if (_inventory._playerInventory[e].Item_Type == "MedicalKit")
		{
			_guiMedicalKitCount++;
		}
				
		if (_inventory._playerInventory[e].Item_Type == "ReconDrone")
		{
			_guiReconDroneCount++;
		}
	}
}
