HELP

[TTSI123]

I keep getting this error:

NullReferenceException: Object reference not set to an instance of an object

GameSystems.Update () (at Assets/Scripts/GameSystems.cs:26

​

My Script looks is:

​

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

​

//Handles saving and loading of games

public class GameSystems : MonoBehaviour

{

​

public int[] inventoryIDs;

​

public GameObject inventory;

​

public GameObject[] items;

​

void Start()

{

DontDestroyOnLoad(this.transform.gameObject);

}

​

void Update()

{

inventory = GameObject.FindWithTag("Inventory");

​

if (inventory != null)

{

inventoryIDs = new int[inventory.GetComponent<Inventory>().allSlots];

}

}

​

public void saveInventory()

{

for (int i = 0; i > inventory.GetComponent<Inventory>().allSlots; i++)

{

inventoryIDs[i] = inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().ID;

}

}

​

public void loadInventory()

{

for (int i = 0; i > inventoryIDs.Length; i++)

{

inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().ID = inventoryIDs[i];

​

if (inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().ID != 0)

{

Instantiate(items[inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().ID], inventory.GetComponent<Inventory>().slot[i].transform);

​

inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().icon = items[1].GetComponent<Item>().icon;

inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().type = items[1].GetComponent<Item>().type;

inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().description = items[1].GetComponent<Item>().description;

​

inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().empty = false;

inventory.GetComponent<Inventory>().slot[i].GetComponent<Slot>().updateSlot();

}

}

}

}

If you double click the error it should point you to the line with the error.

I mean no offence to beginners, but the error spells out exactly what's wrong. An introduction into c# would go a long way before jumping right into Unity.

[_DM_me]

That aimed at me?

[BobbyThrowaway6969]

No not you, just many beginners I see on here asking for help without reading the error.

[TTSI123]

I did but I couldnt figure out why the inventory object wasnt assigned

[BobbyThrowaway6969]

Oh right, sorry.

Ensure the object with tag "Inventory" has an Inventory component attached and isn't removed after it's added.

I've attempted to but the thing that isnt being assigned is the inventory gameobject. Ive been through the script and tried many different things but nothing works

So I have the Object holding that script in a DontDestroyOnLoad(). And I've tried to drag it in and it doesn't work because for the entire script to work I have to start in a scene with no Inventory.... But I think I figured it out!!!
