How can I implement a full-screen toggle feature in my indie game similar to Undertale?

Implementing a Full-Screen Toggle Feature

Creating a full-screen toggle feature in your indie game, akin to what is seen in games like Undertale, involves a blend of user interface controls and graphics settings management. Here’s a step-by-step guide on how to achieve this.

Step 1: Set Up Your Game Environment

Ensure your game engine, such as Unity or Unreal Engine, supports customizable display settings. This feature often involves manipulating game window properties and requires some familiarity with the engine’s graphics API.

Step 2: Create a Toggle Functionality

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

This simple C# script can handle full-screen toggling in Unity. You can attach this function to a button or a key press event in your game’s settings menu.

Step 3: Managing Screen Resolutions

Providing resolution options enhances user experience. Allow players to choose between windowed and full-screen modes with different resolutions considered, matching the approach used in Undertale-inspired titles.

Step 4: Saving User Settings

Implement persistence by saving display settings across game sessions. In Unity, you can use PlayerPrefs to store user preferences:PlayerPrefs.SetInt("fullscreen", Screen.fullScreen ? 1 : 0);

Step 5: Testing and Optimization

• Test on various platforms and displays to ensure compatibility.
• Optimize rendering to prevent performance drops when switching modes.

This approach ensures you provide a polished user experience with customizable screen modes, enhancing the overall gameplay experience.
