Luna provides a set of Jake tasks which can be used to export your Unity project via the command line (terminal/console).
Using the command line provides greater flexibility and more verbose logs.
To use the command line with the Luna Package you must be signed into the Luna Plugin in Unity.
Not doing so will produce a “Authentication failed” error when trying to run the Jake tasks.
After signing in you now need to set the package as your working directory.
$ cd Projects/LunaPackages/1.11.0
If the directory is set correctly, then listing the folder's contents using
ls will look like this:
$ ls config.json engine jake pipeline scripts tools
Now you need to set the project path for your current Unity project. The command differs slightly for Mac and Windows OS.
$ export PROJECT_PATH=/d/Projects/Studio.Game
> set PROJECT_PATH=C:/Projects/Studio.Game
Once your path is set, you will be able to us Jake tasks to execute the equivalent stages from the Luna Playable Unity UI.
$ ./jake project:build
> tools\node\win64\node.exe pipeline\node_modules\jake\bin\cli.js -f pipeline\Jakefile.js project:build
This will begin building a develop build of the project using the settings you have chosen in the Luna Playable Unity UI. Once complete, you can run this in the browser as normal.
You can also create a Playground build using Jake tasks, which will compile all the relevant assets and code into a Playground archive.
$ ./jake project:build TARGET_PLATFORM=playground
> tools\node\win64\node.exe pipeline\node_modules\jake\bin\cli.js -f pipeline\Jakefile.js project:build TARGET_PLATFORM=playground
You can also generate a size breakdown of your Luna builds by using add-ons in your Jake tasks.
STATS in the build command will add a size breakdown of the compiled assets. You may use the STATS options, 1 and 2, to display a less and more detailed report respectively.
$ ./jake project:build STATS=1
> tools\node\win64\node.exe pipeline\node_modules\jake\bin\cli.js -f pipeline\Jakefile.js project:build STATS=1
STATS=1 : A shortened report.
`STATS=2` : Full report
You also have more discrete control over which part of the Luna export process you run. For example, if you make a change to your user code but not to your assets, you can start from the
code:bundle command (Stage 3).
When you run
project:build, you are effectively executing the following commands in order:
./jake unity:export- Exports all assets from Unity project
./jake assets:bundle- Compiles and compresses assets
./jake code:bundle- Bridge engine compiles code from C# to JS
./jake package:bundle- Bundles into HTML package
