How to check if a specific gameobject is in the array?

Questions & Answers
1

I am working on a different inventory type system. What I would like it do here is be able to search the array, and if there is in fact a “Sphere” in the array, tell the user they have 1 or more Spheres. Not sure if it is possible, or maybe I should be using a list. Not sure. Any advice or tips??

here is the inventory script. I have other scripts to add items to the array already.

using UnityEngine;
using System.Collections;

public class Inventory : MonoBehaviour {

    public GameObject[] items;


	// Use this for initialization
	void Start () 
    {
        
	}
	
	// Update is called once per frame
	void Update () 
    {
	
	}

    void OnGUI()
    {
        //Insted of indexing of a specific, I want to check if any gameobject in items 
        //is equal to FindWithTag "Sphere". Is that possible?
        if (items[0] == GameObject.FindWithTag("Sphere"))
        {
            GUI.Label(new Rect(100, 100, 100, 100), "You have a (or this many) sphere(s)");
        }

    }

If the array list is dynamic and you can add/delete entries, then just don’t use an array but a generic List (add “using System.Collections.Generic” at top of your script) and use Contains():

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

public class Test : MonoBehaviour {

	public List<GameObject> items;

	void OnGUI()
	{
	GameObject sphere = GameObject.FindWithTag("Sphere");
	if (sphere != null && items.Contains(sphere))
		{
			GUI.Label(new Rect(100, 100, 100, 100), "You have a (or this many) sphere(s)");
		}
	}

}

To add a GameObject to the list: items.Add(yourGO);
To remove from the list: items.Remove(yourGO);
