14: Live Assist Panels – Chyron

Overview

The Live Assist Panels allow you to design web based user panels to control elements of the Unreal projects, such as Cameras, lights, objects positions, etc.

The Live Assist Panel web server needs to be launched manually using the dedicated desktop shortcut. Run it to start the web server. You should get the following output:

Open Chrome and type in the following URL to open the Panel web page: http://localhost/

From the left menu select Panels and the press Add.

Give a name to the Panel and set its size.

This will open an empty Layout window with menus on the sides.

On the bottom left one you will find commands that can be added to the layout by clicking on them.

Start by adding a button and resize it manually to a decent size.

Commands and Actions that are triggered when pressing that button are written as Functions in Lua scripting language within the Code tab at the top left.

Those Functions are then called by the Button from the Commands tab at the bottom right:
