Hello.
Fairly new to coding so I’m really struggling how to code this. I have followed a youtube tutorial to get a whole inventory system working in my game.
I’ve also added a bow and arrow that can fire arrows, it has a number of arrows that goes down after each shot but i’d like that number to correspond to one of my arrow items in my inventory, so I pick up (or craft) 10 arrows, it goes into my inventory and my bow script updates the amount of arrows left.
Here are my scripts.
—SCRIPT FOR EACH ITEM—
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Item : MonoBehaviour
{
public string equipmentType;
public int equipmentIndex;
public Sprite itemSprite;
public int amountInStack = 1;
public int maxStackSize = 1000;
public int itemID;
}
—SCRIPT FOR EACH SLOT—
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
using UnityEngine;
public class Slot : MonoBehaviour
{
public Item slotsItem;
Sprite defaultSprite;
Text amountText;
public void CustomStart()
{
defaultSprite = GetComponent<Image>().sprite;
amountText = transform.GetChild(0).GetComponent<Text>();
amountText.text = "";
}
public void DropItem()
{
if(slotsItem)
{
slotsItem.transform.parent = null;
slotsItem.gameObject.SetActive(true);
slotsItem.transform.position = Vector3.zero;
}
}
public void CheckForItem()
{
if(transform.childCount > 1)
{
slotsItem = transform.GetChild(1).GetComponent<Item>();
GetComponent<Image>().sprite = slotsItem.itemSprite;
if (slotsItem.amountInStack > 1)
amountText.text = slotsItem.amountInStack.ToString();
}
else
{
slotsItem = null;
GetComponent<Image>().sprite = defaultSprite;
amountText.text = "";
}

Thanks soo much if you’ve read all of this, I know its a lot. But just an idea in the right direction would help soo much. (sorry if it’s a little messy, not sure how to copy/paste the scripts properly)
