need help deleting ammo item in inventory on gun reload

Elaborate on the GUI Inventory system: List/Array/something else? You want to find the item in your Inventory system and remove it - right? Something like Inventory.Remove(theItem)

I'm using Brackeys free inventory system. I believe it is an Array. Here is the main part of his inventory code.

 var Contents : Transform[]; //The content of the Inventory
 var $$anonymous$$axContent : int = 12; //The maximum number of items the Player can carry.
 
 var Debug$$anonymous$$ode = false;     
 private var playersInvDisplay : InventoryDisplay; //$$anonymous$$eep track of the InventoryDisplay script.
 
 static var itemHolderObject : Transform; //The object the unactive items are going to be parented to. In most cases this is going to be the Inventory object itself.
 
 @script AddComponent$$anonymous$$enu ("Inventory/Inventory")
 
 //Handle components and assign the itemHolderObject.
 function Awake ()
 {
     itemHolderObject = gameObject.transform;
     
     playersInvDisplay = GetComponent(InventoryDisplay);
     if (playersInvDisplay == null)
     {
         Debug.LogError("No Inventory Display script was found on " + transform.name + " but an Inventory script was.");
         Debug.LogError("Unless a Inventory Display script is added the Inventory won't show. Add it to the same gameobject as the Inventory for maximum performance");
     }
 }
 
 //Add an item to the inventory.
 function AddItem(Item:Transform)
 {
     var newContents = new Array(Contents);
     newContents.Add(Item);
     Contents=newContents.ToBuiltin(Transform); //Array to unity builtin array
     
     if (Debug$$anonymous$$ode)
     {
         Debug.Log(Item.name+" has been added to inventroy");
     }
     
     //Tell the InventoryDisplay to update the list.
     if (playersInvDisplay != null)
     {
         playersInvDisplay.UpdateInventoryList();
     }
 }
 
 //Removed an item from the inventory (IT DOESN'T DROP IT).
 function RemoveItem(Item:Transform)
 {
     var newContents=new Array(Contents);
     var index=0;
     var shouldend=false;
     for(var i:Transform in newContents) //Loop through the Items in the Inventory:
     {
         if(i == Item) //When a match is found, remove the Item.
         {
             newContents.RemoveAt(index);
             shouldend=true;
             //No need to continue running through the loop since we found our item.
         }
         index++;
         
         if(shouldend) //Exit the loop
         {
             Contents=newContents.ToBuiltin(Transform);
             if (Debug$$anonymous$$ode)
             {
                 Debug.Log(Item.name+" has been removed from inventroy");
             }
             if (playersInvDisplay != null)
             {
                 playersInvDisplay.UpdateInventoryList();
             }
             return;
         }
     }
 }
 
 //Dropping an Item from the Inventory
 function DropItem(item)
 {
     gameObject.Send$$anonymous$$essage ("PlayDropItemSound", Send$$anonymous$$essageOptions.DontRequireReceiver); //Play sound
     
     var makeDuplicate = false;
     if (item.stack == 1) //Drop item
     {
         RemoveItem(item.transform);
     }
     else //Drop from stack
     {
         item.stack -= 1;
         makeDuplicate = true;
     }
     
     item.Drop$$anonymous$$eFromThePlayer(makeDuplicate);         
     if (Debug$$anonymous$$ode)
     {
         Debug.Log(item.name + " has been dropped");
     }
 }
 
 

I've tried something like the Inventory.Remove("Ammo test") but it doesn't seem to work properly. Also how would I get it to know how many to delete. Such as I have 2 out of 6 rounds in the gun and reload, using 4, so how would it know to delete 4 "Ammo test" items?

First need to know if 'Ammo' got into Inventory, it looks like it's expecting you to call the method AddItem(Item:Transform) passing it a transform, presumambly the transform of the "ammo"

Did you do that at some point in your code? If so, show that part please.

It gets added in. It's hard to know which part of the code it happens though. As I said, this is Brackeys free inventory system, and it is in several different parts. I think I found it though in another Script called "Items"

 function PickUpItem ()

{ var getit=true; if(canGet){//if its getable or hasnt been gotten.

 playersinv.gameObject.Send$$anonymous$$essage ("PlayPickUpSound", Send$$anonymous$$essageOptions.DontRequireReceiver); //Play sound
 
     if(stackable){
         var locatedit:Item;
         for(var t:Transform in playersinv.Contents){
             if(t.name==this.transform.name){//if the item we wanna stack this on has the same name
                 var i:Item=t.GetComponent(Item);
                 if(i.stack<i.maxStack){
                     locatedit=i;
                 }
             }
         }
         if(locatedit!=null){//if we have a stack to stack it to!
             getit=false;
             locatedit.stack+=1;
             Destroy(this.gameObject);
         }
         else{
             getit=true;
         }
     }
     //If we can get it and the inventory isn't full.
     if (getit && playersinv.Contents.length < playersinv.$$anonymous$$axContent)
     {
         playersinv.AddItem(this.transform);
         $$anonymous$$ove$$anonymous$$eToThePlayer(playersinv.itemHolderObject);//moves the object, to the player
     }
     else if (playersinv.Contents.length >= playersinv.$$anonymous$$axContent)
     {
         Debug.Log("Inventory is full");
     }
 }

}
