Unity MultiBuild

What it does

Provides you with a simple in-editor interface to build for multiple platforms at once.

How to use (Interactive)

1. From the menu, click Tools > MultiBuild...
2. Choose a base output folder (each platform will build into a subfolder)
3. Add the platforms you want to build for
4. Click the green build button

How to use (Command line)

Option 1: Build using all settings last saved in UI

Unity -quit -batchmode -executeMethod MultiBuild.Builder.Build

This invokes MultiBuild using all the settings you specified when you last used the UI (you have to have used it at least once or this will fail). Includes the output folder, the targets you picked, and whether it was development mode etc.

Option 2: Build using settings specified on command line

Unity -quit -batchmode -executeMethod MultiBuild.Builder.BuildCommandLine <outputFolder> <is_dev> <targetName> [targetName...]

In this mode you specify the output folder, whether to build in development mode (just a 'true' or 'false'), and a list of targets, which must match the entries in the Target enum in Settings.cs, e.g. "Win64".

This mode is useful because there is no standard way to build a development mode player in Unity from the command line right now.

More details

• The scenes that are built are the ones you've selected in Build Settings
• By default the project name is used as a base for all output, but you can disable that and provide a different name if you like
• Your settings are saved in your project at Assets/MultiBuild/MultiBuildSettings.asset
• After finishing the build, the active target is reset to whatever it was before you started the build
• Be aware that I've only really tested this with the standalone builds right now

Why?

I often build for several platforms and found it tedious to keep switching in the Build Settings window. It was useful to me to be able to build both with the Unity editor still open (you can't use the command line build when it's open), and to be able to use the saved settings from the command line.

Even if you use the full command line mode where you specify all the targets, it's simpler when using a lot of targets (shared base folder, automatic subfolders), plus you can also change the "Development mode" flag with this tool, which you cannot with the vanilla Unity command line build.

Contributing

I'm not going to be spending loads of time on this so if you want a new feature or you find a problem with one of the targets (or want to add more of them), please fork and submit a pull request in the first instance. All contributions welcome!
