How can I make the game fullscreen in Godot such that the pixels themselves get bigger?

Implementing Fullscreen Mode with Enlarged Pixels in Godot

Understanding the Concept

To create a fullscreen experience where the pixels themselves appear larger, the strategy involves scaling the viewport rather than adjusting the screen resolution. This can give the game a retro, pixel-art style that many developers and players find appealing.

Steps to Implement Fullscreen with Enlarged Pixels

1. Adjust the Viewport Settings: In Godot, go to the Project Settings. Look for the Display category and find the Window subgroup. Set stretch_mode to 2d and stretch_aspect to keep.
2. Set the Render Scale: Under the same Window settings, adjust the render_scale setting to control how much the pixels should be enlarged.
3. Toggle Fullscreen Mode: Use a script to toggle fullscreen mode. You can attach this to a dedicated button or trigger it automatically at startup. Here’s a simple GDScript example:

   func _ready():
       OS.window_fullscreen = true

Common Pitfalls and Troubleshooting

• Non-Pixel-Perfect Artifacts: Ensure your assets are aligned with the grid and consider using a pixel-perfect camera plugin to avoid distortions.
• Performance Issues: Enlarging pixels effectively reduces resolution, which might lower rendering workload, but make sure to profile performance for any unexpected bottlenecks.

Enhancing User Experience

Consider adding toggles or sliders in the UI for players to adjust the scale and seek their preferred visual experience. This marks the project’s responsiveness to different equipment capabilities.
