Fullscreen Game View

This package allows toggling the Unity Game View to fullscreen mode by pressing F12 during Play mode.

How It Works

The package uses reflection and Harmony to modify internal Unity Editor behavior.
Note: Due to reliance on internal APIs, future Unity updates may break compatibility.
This solution has been tested and confirmed working with Unity 2022.3.

Known Issues

• Monitor Limitation: Fullscreen currently works reliably only on the monitor on which Unity was initially launched.
• Startup Error: An error might appear upon opening Unity if Burst is enabled. This error is harmless and can be safely ignored.
• Performance: In some configurations, the Game View may render twice, potentially impacting performance.
