I have an inventory script that creates an a button at the bottom of the screen for the items in the inventory, but I am encountering an issue as it currently simply has text, where as I want a different image in each box.

I have linked the script below to show my issue:

pragma strict

ar obj_wood : GameObject;

var obj_claw : GameObject;

var obj_bread : GameObject;

var obj_water : GameObject;

var numberOfItems : Number;

public var items = new System.Collections.Generic.Dictionary. ();

private var curItem : System.Collections.Generic.KeyValuePair. ;

public var buttonHeight = 50;

public var width = 100;

AddItemToInventory(obj_wood);

AddItemToInventory(obj_claw);

AddItemToInventory(obj_bread);

AddItemToInventory(obj_water);

function AddItemToInventory (item : GameObject) {

  items.Add(item.name, item);
 
  Destroy(item);

}

function OnGUI() { var curIndex = 0;

     GUI.BeginGroup (new Rect (400, 300, 400, 120));

for(var item : System.Collections.Generic.KeyValuePair. in items) {

          var rect : Rect = new Rect((width+2) * curIndex, 0, width, buttonHeight);
 
          var itemTexture : Texture = "icon_"+item.key;

//i have called each texture icon_"item name", but the texture variable wont accept a string

          if(GUI.Button(rect, itemTexture)) {
                curItem = item;
                
               RemoveItem(item);
          }
          curIndex++;
     }

     GUI.EndGroup();

}

function RemoveItem (item : System.Collections.Generic.KeyValuePair. ) {

  yield WaitForEndOfFrame;
 
  items.Remove(item.Key);

}

function RemoveItem (item : GameObject) {

  yield WaitForEndOfFrame;
 
  items.Remove(item.name);

}
