Creating a Difficulty System toggle switch

Overview:

In this article we check out how we can make a simple Difficulty System using the toggle switch UI in Unity

Project Set Up:

1. Create an empty gameobject, name it ToggleGroup and attach a Toggle Group Component. Make sure to check Allow Switch Off.

2. Create three toggles as children of the ToggleGroup Object.

3. Create and add a script named DifficultySystem to the ToggleGroup Object.

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

public class DifficultySystem : MonoBehaviour
{
   [SerializeField] private List<Toggle> _difficultyToggle = new List<Toggle>();

    private void Start()
    {
        foreach (Transform child in this.gameObject.transform)
        {
            var toggle = child.gameObject.GetComponent<Toggle>();
            _difficultyToggle.Add(toggle);
        }
    }

    public void SelectDifficulty(int difficulty)
    {
        if (difficulty == 0 && _difficultyToggle[0].isOn)
        {
            Debug.Log("Difficulty Selected: Easy");
        }
        else if (difficulty == 1 && _difficultyToggle[1].isOn)
        {
            Debug.Log("Difficulty Selected: Medium");
        }
        else if (difficulty == 2 && _difficultyToggle[2].isOn)
        {
            Debug.Log("Difficulty Selected: Hard");
        }
    }
}

4. Select each toggle and assign the Difficulty Script and set the appropriate value. 0 for easy, 1 for medium and 3 for hard. Make sure to assign the ToggleGroup to the Group slot.

Now when you select each toggle it should print what you picked.

Thats it for this article.
