Hi everyones,

How to make an inventory with 3 Storage. For example :

if i push storage 1 button it will show 20 Slots at inventory,

if i push storage 2 button it will show from 21 Slots until 40 Slots at inventory, and

if i push storage 3 button it will show from 41 Slots until 60 Slots at inventory.

so it have all 60 slots total.

Below its my code :

inventory.cs

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

public class inventory : MonoBehaviour {
	public List<GameObject> slotsx = new List<GameObject> ();
	public player Player;
	public List<item> itemx = new List<item> ();
	public GameObject slots;

	item itemxs;
	public int indexofdragitem;
	public Sprite icon;

	int sisa;
	itemDatabase database;
	int totalSlot = 60;
	int currentStorage = 1;
	int view = 20;

	// Use this for initialization
	void Start () {
		Player = new player();
		int slotAmount = 0;
		database = GameObject.FindGameObjectWithTag ("itemDatabase").GetComponent<itemDatabase> ();


		//Generate the Slot and Slot Name;
		for(int i = 1; i <= 60; i++) {
				GameObject Slot = (GameObject) Instantiate(slots);
				Slot.GetComponent<slotScript>().slotNumber = slotAmount;
				
				slotsx.Add(Slot);
				
				Player.items.Add(new item());
				addChilParent (this.gameObject,Slot);
				//Slot.transform.parent = this.gameObject.transform;
				Slot.name = "slot-" + i;
				slotAmount++;

		}

	}

	//Add Slot Child To GridSlot Game Object
	public void addChilParent(GameObject parentx, GameObject childx) {
		childx.transform.SetParent (parentx.gameObject.transform);
	}

}

Thanks

Paging can easily be achieve with LINQ, for example:

int pageLimit = 20;
IEnumerable<item> items = new List<item>(); 
// then populate your items as you usually would.

IEnumerable<item> GetPagedItems(int pageNum)
{
    return items.skip((pageNum - 1) * pageLimit).Take(pageLimit);
}
