Ok, lets setup UWB's development environment.
These prerequisites are mandatory to compile UWB.
Unity 2021.3.x .NET 6 SDK PowerShell (formally PowerShell Core)* Git
*Modern PowerShell is required! The one built into Windows does NOT work.
Additional Optional Prerequisites
These prerequisites are not required, but some areas may require them.
We first need to obtain UWB's code. UWB is all contained in one-mono repo, found at
To get the
UnityWebBrowser repo, you first need to clone the repo recursively using Git, like so:
git clone --recursive https://github.com/Voltstro-Studios/UnityWebBrowser.git
If you did NOT clone the repo recursively, you can just init the submodules by running these commands at the root of the repo:
git submodule init git submodule update
Once you have the repo cloned with the submodules, you must now run the
src/setup-all.ps1 script with PowerShell.
You can go into PowerShell with the command:
Once in PowerShell, go to the
src/ directory, and run the
Depending on your system, and your download speeds, this script could take upto a minute or longer. You only need to run this once.
You can now open up the
src/UnityWebBrowser.UnityProject project with Unity.
Once in Unity, you can open the provided
UWB scene provided in the project. By default, this scene is setup to have basic browser controls/window.
When running the project in this scene, a provided 'UWB Debug UI' will be available.
By default this is "hidden", you can open the UI via the small panel at the top of the player's window.
The 'UWB Debug UI' provided has some useful stats and controls that you may want to use.
If you need to, extra controls can be added by modifying the
(In the future we hope to develop more editor tools to make life easier.)
There a many dev scripts in the
src/DevScripts directory. The main ones that you will most likely use are:
