How can I implement a fullscreen toggle feature in my RPG to enhance player experience, similar to what is used in games like Undertale and Deltarune?

Implementing a Fullscreen Toggle Feature

In many RPGs, such as Undertale and Deltarune, enabling a fullscreen toggle enhances player immersion and comfort. Implementing this feature involves modifying your game’s user interface settings and input handling.

Steps to Implement Fullscreen Toggle

1. Detect and Handle Input: Use an input system to detect a key press or UI button click to toggle fullscreen mode. For instance, you can use the ‘F11’ key or a dedicated button in the game’s settings menu.
2. Change Screen Modes: In Unity, you can leverage the Screen.fullScreen property. Toggle this property based on the user’s action:

void Update() { if (Input.GetKeyDown(KeyCode.F11)) { Screen.fullScreen = !Screen.fullScreen; } }

3. Adjust UI Elements: Ensure that UI elements scale and position correctly in both windowed and fullscreen modes. Using anchor presets and flexible grid layouts can help maintain consistency.
4. Save User Preferences: Store user preferences for screen mode using PlayerPrefs, allowing the game to remember the user’s choice for future sessions:

void SaveScreenPreference() { PlayerPrefs.SetInt("fullscreen", Screen.fullScreen ? 1 : 0); }

5. Enhance Player Experience: Consider smooth transitions and visual indicators when switching modes to enhance the overall user experience.

Additional Considerations

• Cross-Platform Compatibility: Ensure your fullscreen toggle functionality works across different platforms and displays. Test on various aspect ratios to prevent graphical issues.
• Performance Impact: Monitor any performance impact due to resolution changes; optimize by balancing graphic quality settings.
