creating a public integer?

Unity Engine
1

look i was looking like everywhere and nothing helped me i just need an integer i tried GameController and creaing an empty game object nothing worked

2

also i am new to unity and c#

Make a new script, make a public int inside the class’ curly braces { }, drag and drop the script on your empty game object. Like this:

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

public class SomeClass : MonoBehaviour
{
    public int myInteger = 162;
}

I would highly recommend taking a C# fundamentals tutorial series on Youtube before diving in to this, or use https://learn.unity.com/.

It’s going to be a massive struggle otherwise.

Welcome, and good luck!

If you say you’ve tried looking everywhere without specific examples we can do generally do very little except link to a tutorial which you may or may not have already tried. Pick one approach you’ve attempted, and then describe in what way that approach didn’t work.

Hey Tobik,

as I don’t have too much information, I’d like to point you in two possible ways:
A) Singletons
B) ScriptableObjects

The later might be the better solution for you as it’s easier but as we don’t have too much information about your requirements, I might be totally wrong.

Here a link for a start:

When I try to make a public int there a error saying “{ expected” and I’m doing nothing wrong.

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

public class SpawnManager : MonoBehaviour
{
    public GameObject[] prehabsIndex;
    public int animalIndex = 1;

    // Start is called before the first frame update
    void Start()
    {
       
    }

    // Update is called once per frame
    void Update()
    {
        if (GetKeyDown.(KeyCode.S))
        {
            instantiate(prehabsIndex[animalIndex], new Vector3(0, 0, 20), prehabsIndex[animalIndex]);
        }
    }

Except that you’re a) necro-posting and b) forgetting to put a semicolon after your statement.

What do you mean I put a semicolon after my public int statement

What is the method GetKeyDown.? There is no such thing in Unity.
You have Input.GetKeyDown.

What is ___i___nstantiate? With a small “i”? Because the Unity method is with capital “I”.

Please create your own thread and don’t necropost.

Thanks.
