[TUTORIAL] Unity3D – Signing and Packaging your game for the Mac AppStore and Outside !

I spent some times to understand the way to sign and package an .app generated from Unity3D for the Mac AppStore or for outside of it. The workflow is quite the same, you will need to type a few lines of code in order to generate the proper files.

The few differences are that you don’t need the “entitlements”  file and the certifactes are different.

If you want to publish your game outside the store, from the Apple Member Center, you will need to generate the “DEVELOPER ID” application and installer certificates. Then install them by drag and dropping them into you keychain access.

For the Mac AppStore, you have to generate the “MAC APP STORE” production application and installer certifcates.

I made a script in order to automate the signing and packaging process. Here it is on GitHub :

:: GitHub File ::
#!/usr/bin/perl use File::Copy; use File::Find; use File::Path; use Cwd; # Exoa SignAndPackage script v1.3 # Author : Anthony Kozak :: exoa.fr # Place this script in the same folder as the generated .app file from Unity # YOU WOULD NEED IN THIS DIRECTOY: # - a filled Info.plist file # - a PlayerIcon.icns file # - a filled entitlements.entitlements file # - a UnityPlayerIcon.png file # YOU CAN CHECK YOUR INSTALLED CERTIFICATES NAMES USING # security find-identity -p codesigning logit("Hello !"); my $app_found = found_app_indir(); my $appName = ask("What's the .app name in this directory ?", $app_found); my $appPath = getcwd .

1) After installing your certifcates, place this script in the same directory as your .app generated by Unity3D

2) Add the optional files in the same directory such as  Info.plist, PlayerIcon.icns,  entitlements.entitlements,  UnityPlayerIcon.png. They will be overridden inside the .app

3) Open a terminal and launch the script ./SignAndPackage.pl

4) Answer the configuration questions and let the script do the job !

 

Note : You can check that your certificates are installed using this command line :

security find-identity -p codesigning

You don’t need to fill the full name of the certifcates when requested. The default values can be good enough. For example if your certificate is called “3rd Party Mac Developer Installer: MY DEVELOPER NAME (68684684)”, you can just enter “3rd Party Mac Developer Installer”.

 Edit: Version 1.1 now available

Edit: Version 1.3 removed the embedded profile that was crashing the Application Loader

Unity3D – Tips when building your game with an Editor script

Here are some basic tricks when you need to build your game by code.

First you can launch a build process with a single line of code, for example :

[MenuItem("Exoa/Build/Android")]
public static void PerformBuildAndroid()
{
	string fullPath = Application.dataPath.Replace("/Assets", "/") + "_BUILDS/android/build.apk";
	// Build Game
	BuildPipeline.BuildPlayer(allScenes, fullPath, BuildTarget.StandaloneWindows, BuildOptions.None);
}

For Android

Then you can install your game on the connected Android device like this :

[MenuItem("Exoa/Build/Install build on Android")]
public static void InstallAndroid()
{
	// Run the game (Process class from System.Diagnostics).
	string fullPath = Application.dataPath.Replace("/Assets", "/") + "_BUILDS/android/build.apk"; 
	proc = new System.Diagnostics.Process();
	proc.StartInfo.FileName = "D:/SDK/android/sdk/platform-tools/adb.exe"; // replace with your adb exe path
	proc.StartInfo.Arguments = "-d install -r " + fullPath;
	proc.Start();
}

Then you can launch the application on the android device like this :

[MenuItem("Exoa/Build/Launch on Android")]
public static void LaunchAndroid()
{
	// Run the game (Process class from System.Diagnostics).
	string fullPath = Application.dataPath.Replace("/Assets", "/") + "_BUILDS/android/build.apk";
	string appid = PlayerSettings.bundleIdentifier;
	proc = new System.Diagnostics.Process();
	proc.StartInfo.FileName = "D:/SDK/android/sdk/platform-tools/adb.exe"; // replace with your adb exe path
	proc.StartInfo.Arguments = "shell am start -n " + appid + "/com.unity3d.player.UnityPlayerNativeActivity"; 
	proc.Start();
}

For Desktop

For desktop releases, you can automatically launch the build with the Process() class :

[MenuItem("Exoa/Build/Run Exe %&r")]
public static void RunGame()
{
	string fullPath = Application.dataPath.Replace("/Assets", "/") + "_BUILDS/win/build.exe";

	// Run the game (Process class from System.Diagnostics).
	Process proc = new Process();
	proc.StartInfo.FileName = fullPath;
	proc.Start();
}

Opening build folder

You can finally automatically open the build folder like Unity do :

[MenuItem("Exoa/Build/Open Build Folder")]
public static void OpenBuildFolder()
{
	string fullPath = Application.dataPath.Replace("/Assets", "/") + "_BUILDS/";
	fullPath = fullPath.Replace("/","\\");
	Debug.Log(fullPath);
	proc = new System.Diagnostics.Process();
	proc.StartInfo.FileName = "explorer.exe";
	proc.StartInfo.Arguments = fullPath;
	proc.Start();
}

Real Time BigData Visualization

 

Here is one of my personal projects about data visualization. My goal was to render different real time data sources in a 3D environment.
You can download the windows release here to try it out !

 

REAL_TIME_ATTACKS_VISUALIZATION REAL_TIME_WEB_ATTACKS_VISUALIZATION

The real time attacks globe is using the Norse Intelligence Service that continuously monitors the networks for suspicious activities.

TWITTER_REAL_TIME_VISUALIZATION

For the twitter globe, I’m using the tweetping data source. WEB_SEARCHES_VISUALIZATION
