Implementing a Fullscreen Toggle in Unity

Introduction

Creating a fullscreen toggle feature in Unity requires manipulation of the display settings and a practical understanding of Unity’s UI system. Below is a step-by-step guide to integrating this feature into your game.

Step 1: Set Up the UI

Open your Unity project and navigate to the scene where you want to add the settings menu.
Create a new UI Canvas by right-clicking in the Hierarchy and selecting UI > Canvas.
Within the Canvas, right-click and add a Toggle element by selecting UI > Toggle.

Step 2: Create the Script

To implement the functionality, create a new C# script named FullscreenToggle.cs and attach it to the Canvas or any empty GameObject.

using UnityEngine;
using UnityEngine.UI;

public class FullscreenToggle : MonoBehaviour {
    public Toggle fullscreenToggle;

    void Start() {
        fullscreenToggle.isOn = Screen.fullScreen;
        fullscreenToggle.onValueChanged.AddListener(delegate {
            ToggleFullscreen(fullscreenToggle);
        });
    }

    public void ToggleFullscreen(Toggle toggle) {
        Screen.fullScreen = toggle.isOn;
    }
}

Step 3: Configure the Toggle

Assign the fullscreenToggle variable in the Inspector by dragging the Toggle component from the Hierarchy into the script’s public field.
Ensure that the Toggle’s Is On property reflects the current fullscreen state by calling Screen.fullScreen in the Start() method.

Step 4: Optimize for User Experience

Input Management: Make sure the toggle button is accessible via keyboard or controller input for better accessibility, by setting “Navigation” settings within the Toggle component.
Resolution Settings: Consider allowing users to select screen resolutions when switching between fullscreen and windowed modes for improved user control.

Conclusion

By following these steps, you can easily integrate a fullscreen toggle feature that enhances the user experience of your game in Unity. Remember to test this feature on different devices to ensure compatibility and performance.
