Inventory help.

I made an inventory script, but the problem is that whenever I try to move an item to a slot behind the item it just sends it back to its original position.

Here's the SlotController class (C#) using UnityEngine; using System.Collections;

public class SlotController : MonoBehaviour {

 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {
     
 }
 
 void OnMouseHover(){
     transform.parent.GetComponent<InventoryController> ().selectedSlot = this.transform;
 }
 
 void OnMouseExit(){
     transform.parent.GetComponent<InventoryController> ().selectedSlot = null;
 }

}

Here's the Item Class (C#) using UnityEngine; using System.Collections;

public class Item : MonoBehaviour {

 public string name;
 public enum Type {equipment, consumable, weapon, tool, misc};
 public Type type;

 public Sprite sprite;

 // Use this for initialization
 void Start () {
 
 }
 
 // Update is called once per frame
 void Update () {
 
 }

 public void OnMouseHover() {
     transform.parent.parent.GetComponent<InventoryController> ().selectedItem = this.transform;    }

}

Here's the InventoryController Class (C#) using UnityEngine; using System.Collections; using UnityEngine.UI;

public class InventoryController : MonoBehaviour {

 public Transform selectedItem, selectedSlot, originalSlot;

 public GameObject slotPrefab, itemPrefab;
 public Vector2 inventorySize = new Vector2 (7, 5);
 public float slotSize;
 public Vector2 WindowSize;

 // Use this for initialization
 void Start () {
     for(int x = 1; x <= inventorySize.x; x++){
         for(int y = 1; y <= inventorySize.y; y++){
             GameObject slot = Instantiate (slotPrefab) as GameObject;
             slot.transform.parent = this.transform;
             slot.name = "slot_"+x+"_"+y;
             slot.GetComponent<RectTransform>().anchoredPosition = new Vector3(WindowSize.x/(inventorySize.x+1)*x, WindowSize.y /(inventorySize.y+1) * -y, 0);

             if(x + (y - 1)*4 <= GameDB.itemList.Count) {
                 GameObject item = Instantiate (itemPrefab) as GameObject;
                 item.transform.parent = slot.transform;
                 item.GetComponent<RectTransform>().anchoredPosition = Vector3.zero;
                 Item i = item.GetComponent<Item>();

                 //Item Component Variables
                 i.name = GameDB.itemList[(x + (y - 1)*4) - 1].name;
                 i.type = GameDB.itemList[(x + (y - 1)*4) - 1].type;
                 i.sprite = GameDB.itemList[(x + (y - 1)*4) - 1].sprite;

                 item.name = i.name;
                 item.GetComponent<Image>().sprite = i.sprite;
             }
         }
     }


 }
 
 // Update is called once per frame
 void Update () {
     if(Input.GetMouseButtonDown(0) && selectedItem != null){
         originalSlot = selectedItem.parent;
         selectedItem.GetComponent<Collider>().enabled = false;
     }
     
     if (Input.GetMouseButton (0) && selectedItem != null) {
         selectedItem.position = Input.mousePosition;
     }
     else if(Input.GetMouseButtonUp(0) && selectedItem != null){
         if(selectedSlot == null) selectedItem.parent = originalSlot;
         else{
             selectedItem.parent = selectedSlot;
         }
         selectedItem.localPosition = Vector3.zero;
         selectedItem.GetComponent<Collider>().enabled = true;
     }
 }

}

using UnityEngine; using System.Collections; using UnityEngine.UI;

public class InventoryController : MonoBehaviour {

 public Transform selectedItem, selectedSlot, originalSlot;

 public GameObject slotPrefab, itemPrefab;
 public Vector2 inventorySize = new Vector2 (7, 5);
 public float slotSize;
 public Vector2 WindowSize;

 // Use this for initialization
 void Start () {
     for(int x = 1; x <= inventorySize.x; x++){
         for(int y = 1; y <= inventorySize.y; y++){
             GameObject slot = Instantiate (slotPrefab) as GameObject;
             slot.transform.parent = this.transform;
             slot.name = "slot_"+x+"_"+y;
             slot.GetComponent<RectTransform>().anchoredPosition = new Vector3(WindowSize.x/(inventorySize.x+1)*x, WindowSize.y /(inventorySize.y+1) * -y, 0);

             if(x + (y - 1)*4 <= GameDB.itemList.Count) {
                 GameObject item = Instantiate (itemPrefab) as GameObject;
                 item.transform.parent = slot.transform;
                 item.GetComponent<RectTransform>().anchoredPosition = Vector3.zero;
                 Item i = item.GetComponent<Item>();

                 //Item Component Variables
                 i.name = GameDB.itemList[(x + (y - 1)*4) - 1].name;
                 i.type = GameDB.itemList[(x + (y - 1)*4) - 1].type;
                 i.sprite = GameDB.itemList[(x + (y - 1)*4) - 1].sprite;

                 item.name = i.name;
                 item.GetComponent<Image>().sprite = i.sprite;
             }
         }
     }


 }
 
 // Update is called once per frame
 void Update () {
     if(Input.GetMouseButtonDown(0) && selectedItem != null){
         originalSlot = selectedItem.parent;
         selectedItem.GetComponent<Collider>().enabled = false;
     }
     
     if (Input.GetMouseButton (0) && selectedItem != null) {
         selectedItem.position = Input.mousePosition;
     }
     else if(Input.GetMouseButtonUp(0) && selectedItem != null){
         if(selectedSlot == null) selectedItem.parent = originalSlot;
         else{
             selectedItem.parent = selectedSlot;
         }
         selectedItem.localPosition = Vector3.zero;
         selectedItem.GetComponent<Collider>().enabled = true;
     }
 }

}

And finally here is the GameDB Class (C#) using UnityEngine; using System.Collections; using System.Collections.Generic;

public class GameDB : MonoBehaviour {

 public Sprite[] sprites;

 public static List<Item> itemList = new List<Item>();
 
 void Start () {
 
     //Item Creation
     Item I1 = new Item ();
     I1.name = "Baseball Bat";
     I1.type = Item.Type.weapon;
     I1.sprite = sprites[1];
     itemList.Add (I1);

     //Item Creation
     Item I2 = new Item ();
     I2.name = "Torch";
     I2.type = Item.Type.tool;
     I2.sprite = sprites[2];
     itemList.Add (I2);

     //Item Creation
     Item I3 = new Item ();
     I3.name = "Lumber Axe";
     I3.type = Item.Type.weapon;
     I3.sprite = sprites[3];
     itemList.Add (I3);

     //Item Creation
     Item I4 = new Item ();
     I4.name = "Fire Axe";
     I4.type = Item.Type.weapon;
     I4.sprite = sprites[4];
     itemList.Add (I4);

     //Item Creation
     Item I5 = new Item ();
     I5.name = "Pipe Wrench";
     I5.type = Item.Type.weapon;
     I5.sprite = sprites[5];
     itemList.Add (I5);


 }

 void Update () {
 
 }

}
