thank you for reading! I was learned to make a Inventory system of gamegrind. now I’m looking to save my inventory , but still can not do it. Please help me !?
Tutorial in here :
This my Inventory script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Inventory : MonoBehaviour {
GameObject inventoryPanel;
public GameObject slotPanel;
ItemDatabase database;
public GameObject inventorySlot;
public GameObject inventoryItem;
int slotAmount;
public List<Item> items = new List<Item>();
public List<GameObject> slots = new List<GameObject>();
public GameObject toolTip;
void Start () {
database = GetComponent<ItemDatabase>();
slotAmount = 20;
inventoryPanel = GameObject.Find("Inventory Panel");
for (int i = 0; i < slotAmount; i++)
{
items.Add(new Item());
slots.Add(Instantiate(inventorySlot));
slots[i].GetComponent<Slot>().id = i;
slots[i].transform.SetParent(slotPanel.transform);
}
}
void Update()
{
if (Input.GetKeyDown(KeyCode.U))
{
AddItem(5);
AddItem(6);
AddItem(7);
}
}
public void AddItem(int id)
{
Item itemToAdd = database.FetchItemByID(id);
if (itemToAdd.Stackable && CheckIfItemIsInInventory(itemToAdd))
{
for (int i = 0; i < items.Count; i++)
{
if (items[i].ID == id)
{
ItemData data = slots[i].transform.GetChild(0).GetComponent<ItemData>();
data.amount++;
data.transform.GetChild(0).GetComponent<Text>().text = data.amount.ToString();
break;
}
}
}
else
{
for (int i = 0; i < items.Count; i++)
{
if (items[i].ID == -1)
{
items[i] = itemToAdd;
GameObject itemObj = Instantiate(inventoryItem);
itemObj.GetComponent<ItemData>().item = itemToAdd;
itemObj.GetComponent<ItemData>().slot = i;
itemObj.transform.SetParent(slots[i].transform);
itemObj.transform.position = Vector2.zero;
itemObj.GetComponent<Image>().sprite = itemToAdd.Sprite;
itemObj.name = itemToAdd.Title;
ItemData data = slots[i].transform.GetChild(0).GetComponent<ItemData>();
data.amount = 1;
break;
}
}
}
}
public void RemoveItem(int id)
{
Item itemToRemove = database.FetchItemByID(id);
if (itemToRemove.Stackable && CheckIfItemIsInInventory(itemToRemove))
{
for (int j = 0; j < items.Count; j++)
{
if (items[j].ID == id)
{
ItemData data = slots[j].transform.GetChild(0).GetComponent<ItemData>();
data.amount--;
data.transform.GetChild(0).GetComponent<Text>().text = data.amount.ToString();
if (data.amount == 0)
{
Destroy(slots[j].transform.GetChild(0).gameObject);
items[j] = new Item();
closealltab();
break;
}
if (data.amount == 1)
{
slots[j].transform.GetChild(0).transform.GetChild(0).GetComponent<Text>().text = "";
break;
}
break;
}
}
}
else
{
for (int i = 0; i < items.Count; i++)
{
if (items[i].ID != -1 && items[i].ID == id)
{
Destroy(slots[i].transform.GetChild(0).gameObject);
items[i] = new Item();
break;
}
}
}
}
bool CheckIfItemIsInInventory(Item item) {
for (int i = 0; i < items.Count; i++)
{
if (items[i].ID == item.ID)
return true;
}
return false;
}
}
And this is ItemDatabase script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using LitJson;
using System.IO;
public class ItemDatabase : MonoBehaviour
{
private List<Item> database = new List<Item>();
private JsonData itemData;
void Start()
{
itemData = JsonMapper.ToObject(File.ReadAllText(Application.dataPath + "/StreamingAssets/Items.json"));
ConstructItemDatabase();
//Debug.Log(FetchItemByID(0).Description);
}
public Item FetchItemByID(int id) {
for (int i = 0; i < database.Count; i++)
if (database [i].ID == id)
return database [i];
return null;
}
void ConstructItemDatabase()
{
for (int i = 0; i < itemData.Count; i++)
{
database.Add(new Item((int)itemData[i]["id"], itemData[i]["title"].ToString(), (int)itemData[i]["value"],
(int)itemData[i]["stats"]["defence"], (int)itemData[i]["stats"]["energy"], itemData[i]["description"].ToString(),
(bool)itemData[i]["stackable"], (int)itemData[i]["rarity"], itemData[i]["slug"].ToString()));
}
}
}
public class Item
{
public int ID { get; set; }
public string Title { get; set; }
public int Value { get; set; }
public int Defence { get; set; }
public int Energy { get; set; }
public string Description { get; set; }
public bool Stackable { get; set; }
public int Rarity { get; set; }
public string Slug { get; set; }
public Sprite Sprite { get; set; }
public Item(int id, string title, int value, int defence, int energy, string description, bool stackable, int rarity, string slug)
{
this.ID = id;
this.Title = title;
this.Value = value;
this.Energy = energy;
this.Defence = defence;
this.Description = description;
this.Stackable = stackable;
this.Rarity = rarity;
this.Slug = slug;
this.Sprite = Resources.Load<Sprite>("Sprites/Items/" + slug);
}
public Item()
{
this.ID = -1;
}
}
ItemData script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using System;
public class ItemData : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler, IPointerEnterHandler,IPointerExitHandler {
public Item item;
public int amount;
public int slot;
private Inventory inv;
private UseItem useItem;
private Tooltip tooltip;
private Vector2 offset;
void Start()
{
inv = GameObject.Find("Inventory").GetComponent<Inventory>();
useItem = GameObject.Find("Inventory").GetComponent<UseItem>();
tooltip = inv.GetComponent<Tooltip>();
this.transform.SetParent(inv.slots[slot].transform);
this.transform.position = inv.slots[slot].transform.position;
}
public void OnBeginDrag(PointerEventData eventData)
{
if (item != null) {
offset = eventData.position - new Vector2(this.transform.position.x, this.transform.position.y);
this.transform.SetParent(this.transform.parent.parent);
this.transform.position = eventData.position - offset;
GetComponent<CanvasGroup>().blocksRaycasts = false;
}
}
public void OnDrag(PointerEventData eventData)
{
if (item != null) {
this.transform.position = eventData.position - offset;
}
}
public void OnEndDrag(PointerEventData eventData)
{
this.transform.SetParent (inv.slots[slot].transform);
this.transform.position = inv.slots [slot].transform.position;
GetComponent<CanvasGroup>().blocksRaycasts = true;
}
public void OnPointerExit(PointerEventData eventData)
{
tooltip.Deactivate();
}
public void OnPointerEnter(PointerEventData eventData)
{
tooltip.Activate(item);
}
}
Thank !!! ^^
