Unity Fullscreen Game View

Open Unity Game View in true fullscreen mode topmost, taskbar hidden, single hotkey. Test your game exactly as it appears in a build, without leaving the editor.

Why?

Unity built-in "Maximize on Play" doesn't actually go fullscreen the taskbar, window borders, and editor chrome stay visible. This tool fixes that with a single editor script.

Features

• ✅ True fullscreen Game View (topmost window, above all others)
• ✅ Automatically hides the Windows taskbar
• ✅ Toggle on/off with Ctrl + Shift + Alt + X
• ✅ Auto-restores taskbar on editor quit or recompile
• ✅ Single file, zero dependencies
• ✅ MIT licensed - use in commercial projects

Installation

Option 1: Manual (recommended)

1. Download FullscreenGameView.cs
2. Place it inside any Editor/ folder in your Unity project
3. Wait for Unity to compile

Option 2: Clone the repo

git clone https://github.com/AO-85/unity-fullscreen-game-view.git

Then copy Assets/Editor/FullscreenGameView.cs into your project.

Usage

Enter Play Mode, then:

• Hotkey: Ctrl + Shift + Alt + X
• Menu: Window → Toggle Fullscreen Game View

Press once to enter fullscreen, press again to exit.

Requirements

• Unity 2020.3 LTS or newer (tested on Unity 6)
• Windows 10 / 11 for taskbar hiding (uses user32.dll)
• Fullscreen view itself works on macOS/Linux, but taskbar API calls are Windows-only

How it works

Uses reflection to instantiate Unity's internal UnityEditor.GameView as a borderless popup, then calls Win32 SetWindowPos with HWND_TOPMOST to keep it above the taskbar and all other windows.
