This tuturial explains how to build application without using the pro edition of Unity3d editor, wich integrates buildpipeline functionalities. Simply by using command line script.

Warning : This tutorial is not useful if you own the Pro Edition of Unity3d, wich already contains a buildpipeline system using Unity3d scriptting (Javascript or CSharp). In this case, go see :

http://docs.unity3d.com/Manual/BuildPlayerPipeline.html http://docs.unity3d.com/Manual/BuildPlayerPipeline.html

Step 1 : Create Project

So create a new project.

alt text

Save your project !

alt text

Step 2 : Close Unity3d !

This an important step because Unity3d only allows a single running instance of Unity3d.

alt text

Step 2 : Create Script

Create a new file named build.bat at the project root folder, next to Assets folder.

alt text

build.bat

"C:\Program Files\Unity\Editor\Unity.exe" -quit -batchmode  -logFile stdout.log -buildWindowsPlayer "builds\build.exe"

Details :

execute unity3d in batchmode / command line :

"C:\Program Files\Unity\Editor\Unity.exe" -quit -batchmode

create a log file containning build console output :

-logFile stdout.log

build the gameproject for windows plateforme :

-buildWindowsPlayer "builds\build.exe"

Demo

Launch build.bat via command line for console output result, or just click on build.bat.

alt text

A new window pops.

alt text

After a while (30 sec), the window closes itself. The build is finished !

Go open the newly created build folder.

alt text

It contains your game executable.

Click on build.exe

alt text

The game launcher appears. Click on Play!

alt text

Then your game launchs.

alt text

(it’s an empty scene here)

Build console output is in stdout.log file, next to build.bat file.

Error (first use only)

Unity3d needs to link your project folder.

Then you need to open your project with Unity3d a first time before building it by command line. For duplicate or moved project folder, you’ll need to reopen the folder with unity3d.
