Easy Movie Texture For Android Version: 2.18

December 4, 2014 / Jan Rabe / 8 Comments

Whoever uses the Easy Movie Texture For Android (Video Texture) version 2.18 and also uses split apks (obbs) in unity might run into problems with the streaming asset sub-folders. It’s a great plugin to handle rendered textures on mobile devices.

However the plugin fails to create sub-directories while copying videos out of the obbs into their respective sub-folders. Which can fixed by adding

Directory.CreateDirectory(Directory.GetParent(write_path).FullName);

1	Directory.CreateDirectory(Directory.GetParent(write_path).FullName);

in the MediaPlayerCtrl.CopyStreamingAssetVideoAndLoad.

So it looks like this:

IEnumerator CopyStreamingAssetVideoAndLoad(string strURL)
    {
        strURL = strURL.Trim();
        
        string write_path = Application.persistentDataPath + "/" + strURL;
        
        if(System.IO.File.Exists(write_path) == false)
        {
            Debug.Log ("CopyStreamingAssetVideoAndLoad : " + strURL);

            Directory.CreateDirectory(Directory.GetParent(write_path).FullName);
        
            WWW www = new WWW(Application.streamingAssetsPath +"/"+ strURL);
            
            yield return www;
            
            if( string.IsNullOrEmpty(www.error))
            {
                Debug.Log (write_path);
                System.IO.File.WriteAllBytes(write_path, www.bytes );
                
                Call_Load("file://"+write_path,0);
            }
            else
            {
                Debug.Log(www.error);
                
            }
            
            www.Dispose();
            www = null;
        }
        else
        {
            Call_Load("file://"+write_path,0);
        }
        
    }

IEnumerator CopyStreamingAssetVideoAndLoad(string strURL)

{

strURL = strURL.Trim();

string write_path = Application.persistentDataPath + "/" + strURL;

if(System.IO.File.Exists(write_path) == false)

{

Debug.Log ("CopyStreamingAssetVideoAndLoad : " + strURL);

Directory.CreateDirectory(Directory.GetParent(write_path).FullName);

WWW www = new WWW(Application.streamingAssetsPath +"/"+ strURL);

yield return www;

if( string.IsNullOrEmpty(www.error))

{

Debug.Log (write_path);

System.IO.File.WriteAllBytes(write_path, www.bytes );

Call_Load("file://"+write_path,0);

}

else

{

Debug.Log(www.error);

}

www.Dispose();

www = null;

}

else

{

Call_Load("file://"+write_path,0);

}

Also in order to have a e.g. complete callback, simply add a

public event Action OnFinished;

1	public event Action OnFinished;

in the same class and call them at the respective m_CurrentState checks:

else if(m_CurrentState == MEDIAPLAYER_STATE.END) 
  if(OnFinished != null)
    OnFinished();

else if(m_CurrentState == MEDIAPLAYER_STATE.END)

if(OnFinished != null)

OnFinished();

I’ve already e-mailed the fix to Lee JaeYun and it will be fixed in a later version presumably, until then use the fix and enjoy.

Unity: Change Build Settings like splash screen, app icon programmatically / dynamically.

February 17, 2014 / Jan Rabe / 1 Comment

For a project at work I needed a way to swap the splash screen, app icon and package name in order to build 8 different themed apps. So here is a way to do it. This script creates a menu entry where you can simply select the specific build and change almost every build setting. Feel free to add any missing qualifier. (UnityEditor.PlayerSettings)

using UnityEngine;
using System.Collections;

#if UNITY_EDITOR
using UnityEditor;
#endif

// inspired by http://www.fugutalk.com/?p=6047
public class ChangeBuildSettings : MonoBehaviour {
	
	#if UNITY_EDITOR
	
	private static string SplashScreen = "Assets/resources/active/SplashScreen.png";
	private static string Icon = "Assets/resources/active/Icon.png";
	private static string Background = "Assets/resources/active/Background.png";
	private static string resourcePath = "Resources/";
	
	private static void GeneralSettings() {
		PlayerSettings.productName = "Random App Name";
		PlayerSettings.Android.bundleVersionCode = 1;
		PlayerSettings.bundleVersion = "1.0";
		PlayerSettings.companyName = "Random Company";
		PlayerSettings.SetScriptingDefineSymbolsForGroup(BuildTargetGroup.Android,"Default");
		PlayerSettings.strippingLevel = StrippingLevel.UseMicroMSCorlib;
	}
	
	private static void SwapAsset(string source, string target) {
		Debug.Log("Using: " + source);
		if (System.IO.File.Exists(target)) {
			Debug.Log("Updating: " + target);
			FileUtil.ReplaceFile(source, target);
		} else {
			Debug.Log("Creating: " + target);
			FileUtil.CopyFileOrDirectory(source, target);
		}
	}
	
	private static void ChangeFontColor(Color color) {
		foreach (var font in GameObject.FindGameObjectsWithTag ("GuiText")) {
			Debug.Log("Changing color for " + font.name);
			font.guiText.color = color;
		}
	}
	
	[MenuItem ("Custom Build Settings/Default")]
	public static void PuzzleSwapDefault() {
		GeneralSettings ();
		//PlayerSettings.productName = "Random App Name: Default";
		PlayerSettings.bundleIdentifier = "com.random.randomapp.default";
		SwapAsset (resourcePath + "default/Loading-Screen.png", SplashScreen);
		SwapAsset (resourcePath + "default/Background.png", Background);
		SwapAsset (resourcePath + "default/AppIcon.png", Icon);
		ChangeFontColor (Color.black);
		AssetDatabase.Refresh();
	}
	
	[MenuItem ("Custom Build Settings/Christmas Edition")]
	public static void PuzzleSwapClouds() {
		GeneralSettings ();
		//PlayerSettings.productName = "Random App: Xmas Special";
		PlayerSettings.bundleIdentifier = "com.random.randomapp.xmas"; // not necessary, except you wanna publish the same app on the market
		SwapAsset (resourcePath + "xmas/Loading-Screen.png", SplashScreen);
		SwapAsset (resourcePath + "xmas/Background.png", Background);

		AssetDatabase.Refresh();

Unity: Start Coroutines on main thread or anything else for that matter

February 15, 2014 / Jan Rabe / 7 Comments

In case you do some asynchronious stuff like updating a game object after a network response in unity, you might come to a point where you want to do something you which can only be done within the unity main thread. So here is a little trick which let’s a certain method be called on the next opportunity of the game loop.

1) Create a gameobject in your scene and add a this script

public class DoOnMainThread : MonoBehaviour {
    	
   public readonly static Queue<Action> ExecuteOnMainThread = new Queue<Action>();
    	
   public void Update()
   {
        // dispatch stuff on main thread
    	while (ExecuteOnMainThread.Count > 0)
    	{
    		ExecuteOnMainThread.Dequeue().Invoke();
    	}
    }
}

public class DoOnMainThread : MonoBehaviour {

public readonly static Queue<Action> ExecuteOnMainThread = new Queue<Action>();

public void Update()

{

// dispatch stuff on main thread

while (ExecuteOnMainThread.Count > 0)

{

ExecuteOnMainThread.Dequeue().Invoke();

}

2) Add your coroutine action into the queue whenever you want to call it like this:

DoOnMainThread.ExecuteOnMainThread.Enqueue(() => {  
    StartCoroutine(randomcoroutine); 
} );

DoOnMainThread.ExecuteOnMainThread.Enqueue(() => {

StartCoroutine(randomcoroutine);

} );

Of course you can add any action to the main queue at any point and whereever you want. Enjoy (:

Java Enums in C#?

February 14, 2014 / Jan Rabe / 0 Comments

I really love C#! Almost all features like delegates, extensions methods, constraints, lambdas, refs, “magic methods”, etc. are really super convinient to use. It’s totally my favorite language so far and trust me I’ve been around with C/C++, Php, Javascript, Java. I pretty much code all the time in C# nowedays.

Probably one feature that Java did way better than C# is the way to extend enums. As stated on this website especially made for java to c# converting people.

Enums are used to create and group together a list of user defined named constants. Although on the surface the enumerated types in C# and Java seem quite similar there are some significant differences in the implementation of enumerated types in both languages. In Java, enumerated types are a full fledged class which means they are typesafe and can be extended by adding methods, fields or even implementing interfaces. Whereas in C#, an enumerated type is simply syntactic sugar around an integral type (typically an int) meaning they cannot be extended and are not typesafe.

You can use enums in Java as collection of concrecte behaviour implementations:

public interface IStringFilterCommand {

  public boolean filter(@NotNull final String source, @NotNull final String searchString);
}

public enum StringFilterCommand implements IStringFilterCommand {

  IS() {
    @Override
    public boolean filter(@NotNull final String source, @NotNull final String searchString) {
      return source.matches(searchString);
    }
  },
  CONTAINS() {
    @Override
    public boolean filter(@NotNull final String source, @NotNull final String searchString) {
      return source.contains(searchString);
    }
  },
  CONTAINS_NOT() {
    @Override
    public boolean filter(@NotNull final String source, @NotNull final String searchString) {
      return !source.contains(searchString);
    }
  },
  STARTS_WITH() {
    @Override
    public boolean filter(@NotNull final String source, @NotNull final String searchString) {
      return source.startsWith(searchString);
    }
  },
  ENDS_WITH() {
    @Override
    public boolean filter(@NotNull final String source, @NotNull final String searchString) {
      return source.endsWith(searchString);
    }
  };
}

IStringFilterCommand filter= getFilterFromSomewhere();
filter.filter("blakeks", "bla");

or directly

StringFilterCommand .STARTS_WITH.filter("blakeks", "bla");

or with static import:

STARTS_WITH.filter("blakeks", "bla");

public interface IStringFilterCommand {

public boolean filter(@NotNull final String source, @NotNull final String searchString);

}

public enum StringFilterCommand implements IStringFilterCommand {

IS() {

@Override
