The Game view

The Game view is rendered from the CamerasA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary
in your application. The Game view displays how your final, built application looks. You need to use one or more Cameras to control what the player sees when they’re using your application.

The Game view is included in the default Unity Editor layout. If the Game view is not oepn, go to Window > General and select Game to open the Game view.

In the Editor, you can toggle between the Game view and the Simulator view. The Simulator view displays how your built application looks on a mobile device.

Play mode

Use Play mode to run your project and test how it works as it would in a built application.

Use the Play mode control buttons in the ToolbarA row of buttons and basic controls at the top of the Unity Editor that allows you to interact with the Editor in various ways (e.g. scaling, translation). More info
See in Glossary
to control the Play mode:

  • Press the Play button to switch the Editor to Play mode.
  • Press the Pause button to pause Play mode.
  • Press the Step button to move Play mode forward by one frame.

In Play mode, any changes you make are temporary and are reset when you exit Play mode. When you enter the Play mode, the Editor darkens parts of the interface outside the Game view.

Using the Simulator view

Use the Simulator view to preview how your built application looks on a mobile device.

To change between Game and Simulator views, in the Game/Simulator tab, select an option from the Game/Simulator menu.

Alternatively, to open the Simulator view, go to Window > General and select Device Simulator. If there are no instances of the Simulator view open, it opens as a floating window. However, if the Simulator view is already open in the Editor, then trying to open the Simulator view from the menu brings it into focus

density of lower-resolution displays and reduce the resolution of the Game view when an aspect ratio is selected. Low Resolution Aspect Ratios is always enabled when the Game view is on a non-Retina display.
VSync (Game view only) Allow syncing. Syncing can be useful when you record a video, for example. The Editor attempts to render the Game view at the refresh rate of the monitor, though this is not guaranteed. When this option is enabled, it can still be useful to maximize the Game view in Play mode to hide other views and reduce the number of views that the Editor renders.
Scale slider Increase or decrease the scale of the Game view. Scroll right to zoom in and examine areas of the Game view in more detail. This slider lets you zoom out to display the entire screen where the device resolution is higher than the Game view window size. You can also use the scroll wheel and middle mouse button to do this while the application is stopped or paused.

Advanced options

Right-click the Game tab to display advanced Game view options.

Advanced Game view options contain:

  • Warn if No Cameras Rendering: Causes the Editor to display a warning if no Cameras are rendering to the screen. For example, use this for diagnosing problems such as accidentally deleting or disabling a Camera. Enable this unless you are intentionally not using Cameras to render your application. This option is enabled by default.
  • Clear Every Frame in Edit Mode: Causes the Editor to clear the Game view from every frame when your application is not playing. This prevents smearing effects while you are configuring your application. Leave this enabled unless you are depending on the previous frame’s contents when not in the Play mode. This option is enabled by default.
