Player setting

The player settings in Unity are a set of configurations that determine various aspects of how your game behaves and appears when it's built and played. Here's an explanation of some important parameters:

Product Name: The product name is the name of your game as it appears to players. This is what players will see when they install or run your game. It's important to choose a catchy and memorable name that represents your game well.

Icons: Icons are the images that represent your game on the player's device, such as on the home screen or in the app drawer. Unity allows you to set different sizes of icons for various devices and resolutions to ensure your game looks good on all platforms.

Version: The version number of your game indicates which iteration or update it is. It's displayed to users when they download or update your game. Incrementing the version number is important for releasing updates and ensuring players have the latest version.

Resolution: The resolution of your game refers to the dimensions (width and height) of the game window or screen where your game is displayed.

Fullscreen Mode: Fullscreen mode determines whether your game runs in fullscreen or windowed mode on the player's device. Here are the common options:

• Fullscreen: The game occupies the entire screen, hiding other applications and desktop elements. This provides the most immersive experience for players;
• Windowed: The game runs in a window on the desktop, allowing players to see other applications and desktop elements while playing. This mode is useful for multitasking or when players prefer to adjust the window size themselves;
• Fullscreen Windowed (Borderless): This mode combines aspects of both fullscreen and windowed modes. The game appears to run in fullscreen mode, but it allows quick access to other applications and desktop elements by not hiding them completely.

Build panel

After finishing the setup in the Build Settings menu, we're ready to build our game. Simply click on the "Build" button, and Unity will prompt you to choose a folder where you want your game to be saved. Once you've selected the destination, Unity will begin compiling your game files. Once the build process is complete, you'll find your game ready to play in the chosen folder. You can now enjoy playing it on your own device or share it with others by distributing the game files.
