New GUI and Inventory problem.

Question

Ok so basically what I have is an inventory with buttons representing objects and when you click on said button I need it to get said object so I can instantiate and do whatever else. However I am getting an argument out of range error after adding the listener to the GUI button.

I have only resently moved to the new GUI from unity 4.6 so I need help to figure it out all over again.

Here is the code that sets the listener to the GUI button in the inventory. It works as the debug registers but it won't assign the gameobject.

     private GameObject eqObject; //the Object that is referenced;
     
                 for(int cnt = 0; cnt < plyrPlayerScript.CurrentInventoryList.Count; ++cnt){
 //The button instantiated for each object.
                     GameObject slt = (GameObject)(Instantiate(ivntSlot));
                     slt.transform.parent = guiIvnt.transform.Find("MaskBox").transform;         
                     //Set Onclick:
                     slt.GetComponent<UnityEngine.UI.Button>().onClick.AddListener(() => {
                         //Ok this works but you need graphics raycaster component on the parent of the buttons otherwise no click1!!!
                         Debug.Log("Works!!!!!!");
     //This is the part that causes the out of range error. What am I not assigning or doing wrong? 
                         eqObject = plyrPlayerScript.CurrentInventoryList[cnt].transform.gameObject;
                         
                     });
     
                     //
                 }    
     
     
     //Thanks.

I think the problem is the delegate void. When you log 'works', please log the 'cnt' varible too. I think it is always count+1. Try make a new function to add listener to button. I think this will be solve your problem:

     for(int cnt = 0; cnt < plyrPlayerScript.CurrentInventoryList.Count; ++cnt) {
         GameObject slt = (GameObject)(Instantiate(ivntSlot));
         slt.transform.parent = guiIvnt.transform.Find("MaskBox").transform;
         AddButtonListener(slt, cnt);
     }
     
     
 void AddButtonListener(GameObject _slt, int _index) {
     _slt.GetComponent<UnityEngine.UI.Button>().onClick.AddListener(() => {                       
         eqObject = plyrPlayerScript.CurrentInventoryList[_index].transform.gameObject;
     });
 }
