How can I implement a full-screen toggle feature in my PC game using Unity?

Implementing a Full-Screen Toggle Feature in Unity

Step 1: Setting Up the Input

First, define a keybinding for toggling the full-screen mode. You can set up this keybinding in Unity’s Input System. For simplicity, let’s assume we’re using the ‘Escape’ key to toggle full-screen.

Step 2: Writing the Script

Create a new C# script in your Unity project. Let’s call it FullscreenToggle.cs. This script will check for the key press and toggle the screen mode accordingly.

using UnityEngine;public class FullscreenToggle : MonoBehaviour{ void Update() { if (Input.GetKeyDown(KeyCode.Escape)) { Screen.fullScreen = !Screen.fullScreen; } }}

Step 3: Attaching the Script

Attach the FullscreenToggle script to a game object in your scene, such as the main camera or an empty game object, to ensure the script runs during the game.

Step 4: Testing the Implementation

Enter play mode in the Unity editor and press the ‘Escape’ key to test the full-screen toggle functionality. The screen should switch between full-screen and windowed mode each time the key is pressed.

Additional Considerations

• Player Settings: Ensure that your game’s player settings allow full-screen mode. You can configure this in File > Build Settings > Player Settings.
• Resolution Management: Consider managing different screen resolutions to maintain optimal display quality in both full-screen and windowed modes.
