Mobile Device Preview

The Device Preview is a feature in the Core Editor that simulates how certain aspects of a game will appear on a mobile device. It will give creators an approximate look and feel to simulate the mobile experience for players.

In the editor toolbar creators will find the Device Preview button that when clicked on will open up the device preview options.

Device Preview Menu

The Device Preview menu will allow creators to enable and disable device preview in preview and edit modes, along with other options to customize the preview display. This allows creators to quickly iterate on UI and games systems that rely on camera view and screen dimensions.

During preview mode, mouse, keyboard, touch, and controller input will change based on the preview mode chosen.

Multiplayer Preview Mode & Portrait Mode

The device preview only works in editor and local preview mode. Multiplayer preview mode is currently not supported.

Only landscape mode is supported for now.

!Device Preview Options

Device frame

When enabling the Device Frame option, the preview area will display the device frame. In addition to simulating the dimensions of mobile devices, it will also reflect the notch on the display if supported by the device selected.

Flip Notch

Using the Flip Notch option will toggle the notch between the left and the right side of the mobile device. Not all mobile devices have this notch, but it is important to test and ensure parts of the UI are not obstructed by the notch.

Show Safe Zone

By enabling the Safe Zone option, the safe zone of the selected device will have the safe zone area displayed where all UI elements will be visible.

The Devices dropdown allows creators to select a specific device to preview.

Device Preview UI

The device preview UI changes depending on where the player touches the screen. For example, when the player touches the left half of the screen, a virtual joystick will appear. The right half of the screen controls the camera's movement when touched.

Default Mobile UI

The default mobile UI has controls that give a player quick access to things such as Mounts, Emotes, and Settings.

Mobile UI Icon Description
Core Menu Minimizes the current game and brings up the Core game browser.
Player Emotes Opens the emote window for the player to select an emote to play.
Player Mounts Opens the mount window for the player to select a mount to ride. Will not show if mounts are disabled for the game.
Settings Opens up the settings window for the player.

Performance Limits

Performance limits track the objects in the project Hierarchy and show the limit numbers for the object count, networked object, and terrain complexity. Creators should try to keep all bars below the limits to give players the best game performance. Reaching any limit will result in a warning, but currently does not block you from publishing.

There are 5 options to choose from that will adjust the object count and limits based on the specified platform and the detail quality level.

High Low High - 30,000 max objects (left), Low - 10,000 max objects (right)

Detail Relevance

Objects in a Client Context will render only if the player's Detail Level is equal to or above this setting. Low+ will ensure that the objects in this context will always render. For example, having a much lower VFX particle density for mobile will give better performance, compared to PC having a higher VFX particle density.
