Target platform resolution: Consider the screen resolution of the target platform.

When creating a fullscreen game in Unity, it is crucial to consider the screen resolution of the target platform. Different platforms have varying screen resolutions, and it is important to ensure that your game displays correctly on all of them.

• Desktop platforms: Most desktop platforms have a wide range of supported screen resolutions, from low resolutions such as 800x600 to high resolutions such as 4K and beyond. It is important to test your game at multiple resolutions to ensure that it scales properly.
• Mobile platforms: Mobile devices typically have smaller screen resolutions than desktop platforms, but they also have a wider variety of aspect ratios. For example, iPhones have a 16:9 aspect ratio, while Android devices can have 16:9, 18:9, or other aspect ratios. When developing for mobile platforms, it is important to consider the different aspect ratios and design your game accordingly.
• Console platforms: Console platforms typically have fixed screen resolutions, such as 720p or 1080p. When developing for consoles, you can focus on optimizing your game for the specific resolution of the target platform.
• Web platforms: Web browsers can support a wide range of screen resolutions, depending on the user's device and browser settings. When developing for web platforms, it is important to use responsive design techniques to ensure that your game scales properly to different resolutions.

By considering the target platform's screen resolution, you can ensure that your fullscreen game provides a consistent and enjoyable experience for players on all devices.

Camera settings: Adjust the camera's field of view and aspect ratio to match the target resolution.

Once you have determined the target platform's screen resolution, you need to adjust the camera's field of view and aspect ratio to match. This will ensure that your game fills the entire screen without any black bars or distortion.

• Field of view: The field of view (FOV) determines how much of the scene the camera can see. For fullscreen games, you typically want to use a FOV that is wide enough to fill the entire screen. However, you may need to adjust the FOV depending on the specific game and art style.
• Aspect ratio: The aspect ratio is the ratio of the width of the screen to the height. Most modern screens have a 16:9 aspect ratio. However, some mobile devices and older monitors may have different aspect ratios. When setting the camera's aspect ratio, you should match it to the aspect ratio of the target platform.
• Camera position and rotation: In addition to the FOV and aspect ratio, you may also need to adjust the camera's position and rotation to ensure that the game is displayed correctly in fullscreen mode. For example, you may need to move the camera back from the scene to get a wider view.
• Orthographic vs. perspective: By default, the camera in Unity uses a perspective projection. This means that objects closer to the camera appear larger than objects farther away. However, you can also use an orthographic projection, which makes all objects appear the same size regardless of their distance from the camera. Orthographic projection can be useful for certain types of games, such as 2D games or games with a top-down perspective.

By carefully adjusting the camera settings, you can ensure that your fullscreen game provides a visually appealing and immersive experience for players.

Canvas scaler: Use a canvas scaler to ensure UI elements scale correctly across different resolutions.

When creating a fullscreen game in Unity, it is important to use a canvas scaler to ensure that your UI elements scale correctly across different resolutions. Without a canvas scaler, your UI elements may appear too large or too small on different devices.

The canvas scaler is a component that can be added to the canvas object in your scene. It provides a variety of settings that allow you to control how the canvas and its children scale in response to changes in screen resolution.

The most important setting is the scale mode. The scale mode determines how the canvas and its children are scaled. There are four different scale modes to choose from:

• Constant pixel size: This mode scales the canvas and its children so that they maintain the same pixel size regardless of the screen resolution.
• Scale with screen size: This mode scales the canvas and its children so that they maintain the same size relative to the screen size.
• Constant physical size: This mode scales the canvas and its children so that they maintain the same physical size regardless of the screen resolution.
• Scale factor: This mode allows you to specify a custom scale factor that is applied to the canvas and its children.

In addition to the scale mode, the canvas scaler also provides a number of other settings that allow you to fine-tune how the canvas and its children scale. For example, you can specify a minimum and maximum scale factor, and you can control whether the canvas scales in response to changes in screen orientation.

By using a canvas scaler, you can ensure that your UI elements scale correctly across different resolutions, providing a consistent and enjoyable experience for players on all devices.

Build settings: Set the game's resolution and fullscreen mode in the build settings.

Once you have configured your game's camera and canvas scaler, you need to set the game's resolution and fullscreen mode in the build settings. This will ensure that your game runs in fullscreen mode at the correct resolution on the target platform.

• Resolution: In the build settings, you can specify the resolution of your game. You should choose a resolution that is compatible with the target platform and that provides a good игровой опыт for players. For example, if you are targeting mobile devices, you may want to choose a resolution of 1280x720 or 1920x1080.
• Fullscreen mode: You can also specify whether your game should run in fullscreen mode or windowed mode in the build settings. If you want your game to run in fullscreen mode, you should select the "Fullscreen" option. If you want your game to run in windowed mode, you should select the "Windowed" option.
• Other settings: In addition to the resolution and fullscreen mode, there are a number of other settings that you can configure in the build settings. For example, you can specify the target platform, the build type, and the output path.

Once you have configured the build settings, you can build your game and test it on the target platform. Make sure to test your game in both fullscreen mode and windowed mode to ensure that it works correctly in both modes.
