Game View is rendered from the Camera(s) in game. It is representative of final, published game. You will need to use one or more Cameras to control what the player actually sees when they are playing your game. There are three options
- Play : Play the game
- Pause : Pause the game
- Step : Step through the scene step by step
Use the buttons in the Toolbar to control the Editor Play Mode and see how your published game plays. While in Play Mode, any changes you make are temporary, and will be reset when you exit Play Mode. Game view Control Bar options
- Display : Click this to choose from a list of Cameras if you have multiple Cameras in the Scene
- Aspect : Select different values to test how your game will look on monitors with different aspect ratios.
- Low Resolution Aspect Ratios: Check this box if you want to emulate the pixel density of older displays: This reduces the resolution of the Game view when an aspect ratio is selected.
- Scale slider : Scroll right to zoom in and examine areas of the Game screen in more detail. It also allows you to zoom out to see the entire screen where the device resolution is higher than the Game view window size.
- Stats : Click this to toggle the Statistics overlay, which contains Rendering Statistics about your game’s audio and graphics. This is very useful for monitoring the performance of your game while in Play Mode.
- Gizmos: Click this to toggle the visibility of Gizmos. To only see certain types of Gizmo during Play Mode, click the drop-down arrow next to the word Gizmos and only check the boxes of the Gizmo types you want to see.
