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.

Soooo Albért and Marco were visiting me the past week. They needed a couch to crash in Berlin to watch the football world championship. Congrats to Germany by the way for winning the champion ship! Anyways, Marco works as a DJ and he was playing around with his laptop to generate some random sounds. That got me inspired to create a little app over night. It basically loops through a matrix of matrices of tones and plays them that’s why the name Soundlooper. Pure creativity I know, right? xD

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);
		SwapAsset (resourcePath + "xmasAppIcon.png", Icon);

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 (:

Unity: Rescaling Fonts

February 3, 2014 / Jan Rabe / 3 Comments

Hey guys, I’m doing some unity stuff. So far it’s great, however I still have some difficulties about scaling towards respective resolutions for mobile devices.

In general: I appreciate every suggestion!

So far I came across:

GUI.DrawTexture(new Rect (0, 0, Screen.width, Screen.height), texture, ScaleMode.ScaleAndCrop);

1	GUI.DrawTexture(new Rect (0, 0, Screen.width, Screen.height), texture, ScaleMode.ScaleAndCrop);

for scaling simple 2D textures. And a little script for rescaling fonts:

public class RescaleFonts : MonoBehaviour {
	
	private float _oldWidth;
	private float _oldHeight;
	private float _fontSize = 16;
	public float EffectiveFontSizePercent = 0.1f; // value between 0 and 1

	void Update () {
		if (_oldWidth != Screen.width || _oldHeight != Screen.height) {
			_oldWidth = Screen.width;
			_oldHeight = Screen.height;
			_fontSize =  Mathf.Min (Screen.width, Screen.height) * EffectiveFontSizePercent;
			guiText.fontSize = (int) _fontSize;
		}
	}
}

public class RescaleFonts : MonoBehaviour {

private float _oldWidth;

private float _oldHeight;

private float _fontSize = 16;

public float EffectiveFontSizePercent = 0.1f; // value between 0 and 1

void Update () {

if (_oldWidth != Screen.width || _oldHeight != Screen.height) {

_oldWidth = Screen.width;

_oldHeight = Screen.height;

_fontSize = Mathf.Min (Screen.width, Screen.height) * EffectiveFontSizePercent;

guiText.fontSize = (int) _fontSize;

}

Where you add this script to a label or something and change its effective font size. So it will at least look a like amongst multiple devices. It scales all right but it doesn’t feel too reliable yet. Any suggestions?

How do you guys handle your ui sizes with unity?
