I'm really just a beginner and trying to learn game development, but i can't seem to figure out the logic behind this.. if the inventory has already an item inside and if the current object can't be stacked on top of it, then swap out the 2 object
the script i'm trying to implement it:
public void OnDrop(PointerEventData eventData)
{
//on drop if the inventory slot doesn't have child object then we know it's a free slot, so we can drag there the grabbed item.
if(transform.childCount == 0)
{
GameObject dropped = eventData.pointerDrag;
InventoryItem inventoryItem = dropped.GetComponent<InventoryItem>();
inventoryItem.parentAfterDrag = transform;
}
else
{
//on drop if the inventory has already an item inside and if the current object can't be stacked on top of it, then swap out the 2 object
//but how do i know what is the object that is inside this slot?
}
}
}
here is the InventoryManager script:
public class InventoryManager : MonoBehaviour
{
public int maxStackedItems = 4;
int selectedSlot = -1;
public InventorySlot[] inventorySlots;
public GameObject inventoryItemPrefab;
public GameObject mainInventory;
public bool isMainInventoryOpened;
public bool AddItem(Item item)
{
//checks if there is any slot with the same kind of item as this, which isnt in max stack
for (int i = 0; i < inventorySlots.Length; i++)
{
InventorySlot slot = inventorySlots[i];
InventoryItem itemInSlot = slot.GetComponentInChildren<InventoryItem>();
if (itemInSlot != null && itemInSlot.item == item && itemInSlot.count < maxStackedItems && itemInSlot.item.stackable == true)
{
itemInSlot.count++;
itemInSlot.RefreshCount();
return true;
}
}
//looks for an empty slot
for (int i = 0; i < inventorySlots.Length; i++)
{
InventorySlot slot = inventorySlots[i];
InventoryItem itemInSlot = slot.GetComponentInChildren<InventoryItem>();
if(itemInSlot == null)
{
SpawnNewItem(item, slot);
return true;
}
}
return false;
}
void SpawnNewItem(Item item, InventorySlot slot)
{
GameObject newItemGo = Instantiate(inventoryItemPrefab, slot.transform);
InventoryItem inventoryItem = newItemGo.GetComponent<InventoryItem>();
inventoryItem.InitializeItem(item);
}
public Item GetSelectedItem(bool use)
{
InventorySlot slot = inventorySlots[selectedSlot];
InventoryItem itemInSlot = slot.GetComponentInChildren<InventoryItem>();
if (itemInSlot != null)
{
Item item = itemInSlot.item;
if(use == true)
{
itemInSlot.count--;
if(itemInSlot.count <= 0)
{
Destroy(itemInSlot.gameObject);
}
else
{
itemInSlot.RefreshCount();
}
}
return item;
}
return null;
}
}
and the InventoryItem script:
public class InventoryItem : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler
{
[HideInInspector] public Transform parentAfterDrag;
[HideInInspector] public Item item;
[HideInInspector] public int count = 1;
public Image image;
public TMP_Text countText;
public void InitializeItem (Item newItem)
{
item = newItem;
image.sprite = newItem.image;
RefreshCount();
}
public void RefreshCount()
{
countText.text = count.ToString();
bool textActive = count > 1;
countText.gameObject.SetActive(textActive);
}
public void OnBeginDrag(PointerEventData eventData)
{
parentAfterDrag = transform.parent;
transform.SetParent(transform.root);
transform.SetAsLastSibling();
image.raycastTarget = false;
}
public void OnDrag(PointerEventData eventData)
{
transform.position = Input.mousePosition;
}
public void OnEndDrag(PointerEventData eventData)
{
transform.SetParent(parentAfterDrag);
image.raycastTarget = true;
}
}
i've tried to figure out what is the item on that occupied slot but i don't seem to understand this logic yet.

I'm currently working on a game, and now I've just finished the inventory system, which is highly inspired by the one Brackeys made a while back. Right now the player can pick up items, which will go into the inventory's list and be displayed on some UI. After having finished this, I tried to make items stack together, however I was never able to find a working solution. I don't want anything fancy, I just want every item to be able to stack infinitely. If anyone could help me out I'd greatly appreciate it!
Sorry for putting so much code in here, I'm not sure what I should and shouldn't add.

Finally, here's what my hierarchy looks like for my inventory (just replace "inventaire" by "inventory" and don't mind the item names):
If I understand you correctly it sounds like you basically want a counter for the slot so you can add multiple of the Item instance.
You could probably do something like
public class InventorySlot : MonoBehaviour
{
// Have a counter for the amount of items added
int _amount;
Item item;
public Image icon;
public Text amountText;
// optionally add an amount parameter
// if not passed 1 is used but allows to add multiple at once
public void AddItem(Item newItem, int amount = 1)
{
// If there is no item yet
// then simply add the first one
if(!item)
{
item = newItem;
icon.sprite = item.icon;
icon.enabled = true;
_amount = amount;
}
else
{
// Otherwise check first if it is the same item
if(item != newItem)
{
Debug.LogWarning($"Type mismatch between current item {item} and added item {newItem}!", this);
// TODO handle this?
return;
}
// simply increase the amount
_amount += amount;
}
// update text
amountText.text = _amount.ToString();
}
// Again maybe add optional parameter
// if nothing is passed 1 is used
// but allows to remove multiple at once
public void RemoveItem(int amount = 1)
{
// check if enough
if(!item)
{
Debug.LogWarning("This slot is empty! Can't remove", this);
// TODO handle this?
return;
}
if(_amount - amount < 0)
{
Debug.LogWarning($"Not enough items in this slot to remove {amount}!", this);
}
// simply reduce the amount
_amount -= amount;
// update the text
_amountText.text = amount.ToString();
// Only if you reached 0 -> removed the last item
// reset this slot
if(amount == 0)
{
item = null;
icon.sprite = null;
icon.enabled = false;

public void UseItem()

1.i have an issue when i start dragging object its clonning itself, i need that in panel zone(my object respawning in there) not in dropzone im trying to find solution for this can i make clone invisible? if i can how ?here is the code :
enter code here
public class DragHandler : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler

public GameObject x;
public GameObject panel;
public void OnBeginDrag(PointerEventData eventData)
{
placeholder = new GameObject();
placeholder.transform.SetParent(this.transform.parent);
LayoutElement le = placeholder.AddComponent<LayoutElement>();
le.preferredWidth = this.GetComponent<LayoutElement>().preferredWidth;
le.preferredHeight = this.GetComponent<LayoutElement>().preferredHeight;
le.flexibleWidth = 0;
le.flexibleHeight = 0;
placeholder.transform.SetSiblingIndex(this.transform.GetSiblingIndex());
//sibling index kartı aldıgımız yeri döndürür.
Debug.Log("OnBeginDrag");

{

x.transform.SetParent(PlaceholderParent.transform);
//im trying to saying here if the object "this" in drop zone dont instantiate it or make it invisible ??????? but its not working
}

}
public void OnDrag(PointerEventData eventData)
{

//**parentreturnto. getchild(i)**//

// placeholder.transform.SetSiblingIndex(i);
if (PlaceholderParent.transform.GetSiblingIndex() < newSiblingIndex)

If you just want to make a GameObject invisible there are many ways to do it.
You can, for example:
yourGameObject.SetActive(false);
You can also deactivate your gameobject Renderer
yourGameObject.GetComponent<Renderer>().enabled = false;
how to adapt it to your code is up to you.
I am trying to get part of my game working but having trouble solving this problem!
I have boosters that remove game pieces if the user has enough in game coins to use. It is working to an extent and once a booster has been used the coins will decrement but upon exiting and reloading the game it does not update the correct value!
For example, the boosters can be used at a cost of 50 coins, if I have 200 coins and use 4 boosters the value updates to 0 and this works. However if I restart then the value of 200 is still there!
I have a coin manager script set up with playerprefs that gives the user 50 coins after each level, this is linked to the booster script.
Booster class:

Well, this comment basically tells you the problem. If the coin count isn't greater than what was saved previously, it doesn't save!
Change this:
// sets a number of coins into PlayerPrefs if the current coin count is greater
public void SetCoinCount()
{
if (PlayerPrefs.HasKey("TotalCoins"))
{
int oldCoins = PlayerPrefs.GetInt("TotalCoins");
if (currentCoinCount > oldCoins)
{
PlayerPrefs.SetInt("TotalCoins", currentCoinCount);
}
}
}
To this:
// sets a number of coins into PlayerPrefs
public void SetCoinCount()
{
PlayerPrefs.SetInt("TotalCoins", currentCoinCount);
}
So in this game when the player picks up items from the scene I'm trying to have it draw the item in their inventory. The problem is whenever the player picks up an item the sprite is drawn in the wrong area. I'm calling additem from itemid class and sending it to the inventory class. when it is sent the id goes with it and that's how it knows which item to draw. I'm trying to draw it in the next empty slot in the inventory. in the inventory class if I comment in those AddItem(0) (or any number that has an item with it) it draws the sprite in the right location. any ideas on why it is drawing the sprite in the wrong location when it is called from the itemid class

I'm trying to make a simple condition:
If the value I have, is less than the price it costs the item, the button is disabled.
If the value I have, is greater than or equal to the price it costs the item the button is enabled and I can buy it.
But when I test, I have some problems.
First, if I have less than the item cost the button is enabled, and only when I click on it it is when it disables.
Second, if I have less than the item cost and I click on it it disables, but if I get enough to purchase the item, the button is not enabled again.
How do I to be checked these variables all the time? If I have enough the button is enabled if you do not have it disables.
Bellow my scrip:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class BuySkin : MonoBehaviour {

public Button buyBee1;

//Register Button Events
buyBee1.onClick.AddListener (() => buySkin (buyBee1));
