How can I implement a feature in my Unity game that toggles fullscreen mode in Windows 11?

Implementing Fullscreen Toggle in Unity for Windows 11

Implementing a fullscreen toggle feature in a Unity game on Windows 11 can enhance the player experience, providing flexibility and compatibility with various system configurations. Here’s a step-by-step guide:

1. Understanding Fullscreen Modes in Unity

Unity supports several fullscreen modes on Windows, including:

Your chance to win awaits you!

• Exclusive Fullscreen – Provides better performance and lower latency.
• Fullscreen Window – Combines the appearance of fullscreen with the flexibility of windowed mode.
• Windowed – Regular window mode.

2. Setting Up Fullscreen Toggle

Use the Screen.fullScreen property to handle fullscreen toggling. Here is a basic example:

using UnityEngine;

public class FullscreenToggle : MonoBehaviour
{
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.F11) || Input.GetKeyDown(KeyCode.F))
        {
            ToggleFullscreen();
        }
    }

    void ToggleFullscreen()
    {
        Screen.fullScreen = !Screen.fullScreen;
    }
}

3. Handling Resolutions and Display Modes

Ensure your game supports multiple resolutions, which can be done using the Screen.SetResolution method:

void SetGameResolution(int width, int height, bool fullscreen)
{
    Screen.SetResolution(width, height, fullscreen);
}

4. Testing on Windows 11

During testing, verify the toggle works with Windows 11’s fullscreen optimizations. Use shortcuts like Alt + Enter if supported, and check for consistency in rendering and performance.

5. Managing Fullscreen Optimizations

For improved performance tuning, you might need to advise players on enabling or disabling Fullscreen Optimizations:

• Navigating to Settings > System > Display > Graphics settings and configuring it for the particular game executable.

Consider adding UI options in your game settings menu, allowing players to customize their display settings according to their preferences.
