This document outlines how to make your UE Application able to receive inputs from mobile devices. In order to achieve your mobile configuration, it will require modifications to both your Control Panel Config and Unreal Engine (UE) Project.

Control Panel Config

In order to receive touch commands on Mobile devices, enable ‘fakeMouseWithTouches’ in your Config from your Control Panel.

These steps outlined below:

  1. Sign in to your Control Panel (Eagle 3D Streaming | Control Panel).

  2. Go to the ‘CONFIG SELECTION’ and select your targeted config through the dropdown menu.

  3. After the config is selected, click ‘Edit’.

  4. When the config dialog box pops up, select ‘Mouse’.

  5. Click on ‘fakeMouseWithTouches’ so that there is a checkmark inside the checkmark box (shown below).

  6. Click ‘Save’ and close Config dialog box.

Creating Cursor UMG

Touch Interface Setup (Optional)

This section is optional and only required if you would like to enable joystick controls within your application for mobile devices

  1. Create TouchInterface (or Copy from the Engine).

  2. In TouchInterface, set

Actice Opacity = 0.8
Inactive Opacity = 0
This will hide the Interface while used on PC and make visible on Mobile devices.
