U3D

U3d is a set of tools to interact with Unity3D from command line. It is available on Linux, Macintosh and Windows.

What can it do?

U3d provides help for running and installing unity from CLI. Available commands are:

• u3d available: List versions available to download

• u3d install: Download (and install) Unity

• u3d list: List installed versions

• u3d local_install: Install already downloaded packages

• u3d run: Run Unity

Installation

The gem isn't yet on a public repository, so do

./local_gem_install.sh

Security

When you install Unity with this tool, you will have to grant it higher privileges so it can perfrom the installation. It means that under MacOS and Linux, you will be asked for your sudo password.

On Windows, you must launch a administrative command interface to be able to run local_install and install (only if you install for the latter).

Examples

• List installed versions on your computer:

u3d list

• List versions you can download and install from Unity, as well as their packages, on Mac:

u3d available -p -o mac

• Download and install version 5.6.0f3 of Unity with its documentation and the WebPlayer package:

u3d install 5.6.0f3 -p Unity,Documentation,WebPlayer

• Run a CLI on the current project given the configured unity version:

u3d run -- -batchmode -quit -logFile `pwd`/editor.log -executeMethod "WWTK.SimpleBuild.PerformAndroidBuild"

You can get further information on how to use U3d by running u3d --help (or u3d -h).
