  • How to enable reverb in FMOD iOS

    Tags: , iOS

    To enable reverb settings in Fmod Designer click on “Window” > “Reverb Defs”. Select your reverb and click on the play button. The reverb is now active and the project can be built. Notice that for the time being Fmod Designer requires you to always activate this whenever you open your project. This is not done automatically. The name of your reverb, in this case “Reverb00″ is used later on in the code.

    Fmod_designer

    To activate the reverb in the code the follow code needs to be added:

    #import "SoundManager.h"
    #import "mySoundProject.h"
    @implementation SoundManager
    void ERRCHECK(FMOD_RESULT result)
    {
        if (result != FMOD_OK)
        {
            //fprintf(stderr, "FMOD error! (%d) %s\n", result, FMOD_ErrorString(result));
            exit(-1);
        }
    }
    - (id)initWithString:(NSString*)selectedProfile
    {
    system  = NULL;
        eventSystem = NULL;
     
        FMOD_RESULT result      = FMOD_OK;
        char        buffer[200] = {0};
        FMOD_REVERB_PROPERTIES reverb00;
       
        result = FMOD::EventSystem_Create(&eventSystem);
        ERRCHECK(result);
       
        result = eventSystem->init(32, FMOD_INIT_NORMAL | FMOD_INIT_ENABLE_PROFILE  | FMOD_INIT_DISTANCE_FILTERING, NULL, FMOD_EVENT_INIT_NORMAL);
        ERRCHECK(result);
        [[NSString stringWithFormat:@"%@/mySoundProject.fev", [[NSBundle mainBundle] resourcePath]] getCString:buffer maxLength:200 encoding:NSASCIIStringEncoding];
        result = eventSystem->load(buffer, NULL, NULL);
        ERRCHECK(result);
       
        result = eventSystem->getReverbPreset("REVERB00", &reverb00); // Same name as in Fmod Designer.
        ERRCHECK(result);
       
        result = eventSystem->setReverbProperties(&reverb00);
        ERRCHECK(result);
       
        result = eventSystem->getGroup("MySoundProject/MySoundProject", FMOD_EVENT_DEFAULT, &group);
        ERRCHECK(result);

  • Send OSC messages from Unity

    Ellen 11:30 on January 31, 2013 | 1 Permalink | Reply

    Many people wrote to me wondering how to send data from Unity through OSC back to Processing and other applications. Well the answer is simple, write the following code:

    oscListener.oscHandler.Send(Osc.StringToOscMessage(”/Your event name”));

    • Tim 14:18 on February 13, 2013 Permalink

      Hello!
      Thank you for a great example!

      Would it be possible for you to post an full example of sending from unity to processing? I tried this code, but it seems that you need more code in order to get it to work. I’m new at this so that is why im asking. Thank you!

  • Real time blend 2 textures in Unity

    Ellen 08:40 on September 6, 2012 | 3 Permalink | Reply
    Tags: , shaders,

    I had a hard time changing the texture of a game object in real-time where I tried out a movie fading between textures and using Lerp on the material. I wanted it to be dynamic and just be able to pass an argument to my script defining which texture to animate to. Many game objects had different shaders so it didn’t work just to Lerp the current material. So I create custom shaders for different objects that contained 2 textures “_MainTex” and “_Texture2″. I also added the blend option the the shader order to be able to control the blend of the texture from outside. Just adding the shader you can change the blend slider to see the result.

    See example of one diffuse shader with normal map.

    In my javascript I could then pass in which texture to change to and which one to change from.
    I set the textures I want to change between. These are set in the inspector of athouring environment of Unity and passed to the script.

    var firstTexture:Texture;
    var secondTexture:Texture;
    var thirdTexture:Texture;

    The script starts out with setting the default texture of the chosen game object. The game object could have been passed to the script as well. :-)

    function Start () {
        textureObject = gameObject.Find("myTextureObject");
        textureObject.renderer.material.SetFloat( "_Blend", 1 ); // Setting the current texture to be 100% visible
    }

    The public function changeTexture can be accessed from outside to recieve arguments for new textures. newTexture is used to store the new texture as soon as it is time to animate.

    public function changeTexture(myArg : float) {
      yield WaitForSeconds(0.3);

      if(myArg == 1) {
          newTexture = firstTexture;
      } else if (myArg == 2){
          newTexture = secondTexture;
      } else if (myArg == 3){
          newTexture = thirdTexture;
      }

      textureObject.renderer.material.mainTexture = newTexture;
      triggerChange = true;
    }

    In the update function the script always checks if it should change to a new texture. If changeTexture was called it starts blending to the new texture. At the end it sets the old texture to the new one and resets the blend:

    function Update () {
         if(triggerChange == true) {
              changeCount = changeCount - 0.05;

              textureObject.renderer.material.SetFloat( "_Blend", changeCount );
              if(changeCount <= 0) {
                   triggerChange = false;
                   changeCount = 1.0;
                   textureObject.renderer.material.SetTexture ("_Texture2", newTexture);
                   textureObject.renderer.material.SetFloat( "_Blend", 1);
              }

         }
    }

    BlendTextures.js is the entire javascript file of the script above.

    To implement this in Unity follow these steps:
    1. Add your script to the scene. Select the textures and normalmap you defined as public variables in BlendTextures.js.
    2. Create a material and choose your custom shader.
    3. Add the material to your game object.

    blend_textures_unity

    Read up on how to create your custom shaders in the Unity Documentation.

    • Marco Vidaurre 09:12 on December 23, 2012 Permalink

      Hi,

      Nice shader.

      Is there a shader for iOS or mobile that can do this efficiently?

    Test your Unity project with the Processing Osc Demo. Send your events through the Processing app and see them appear in the Unity project. There is also a timer in Processing sending events at all time changing the width of a cube in Unity. Download the Unity OSC example here.

    • Jeroen Boumans 20:35 on August 13, 2012 Permalink

      is it also possible to write towards a LED on the arduino board via Unity > Processing? For example if i press a GUI button in unity, a boole will be “true” and so a signal will be written towards processing, that activates the LED.

    • Ellen 07:44 on September 6, 2012 Permalink

      @Jeroen Boumans You can send osc events from Unity with the following code:
      oscListener.oscHandler.Send(Osc.StringToOscMessage(”/Your event name”));

    • Rufael 13:12 on February 11, 2013 Permalink

      Hello Ellen! We are a group of students who plan to use this example for a project. Your example works perfectly between Unity and Processing but we would like to use the Processing-sketch on Android.
      There are some things that are problematic, for example the Serial library for Processing that does not work on Android.
      Do you have any tips on how to go about doing that? To get the Processing Sketch to work on Android so that one can send messages to Unity wirelessly.
      Great work otherwise!

      Actually, we figured it out. You just have to tweak the ip-adresses a bit! Thanks anyway!

    Interacting with installations with a long life time we turn to heavy duty sensors that can handle a lot of cycles. The string and pull sensors below can handle more than a million cycles and are built for industrial use. They can also be connected to circuit board like Arduino.

    Check out all the pull sensors and string pots from Celesco. Novotechnik also offers a wide range of pull sensors.

    Check out this Processing and Arduino project by nhw3030 with Celesco string sensors.

    I did a test connecting Arduino and Unity with the help of Processing and a Open Sound Control library. When I am pushing the Flexi Force sensor the values affect a cube within Unity. To get this setup do the following:

    Arduino
    Load the Standard Firmdata on to your Arduino. Check out a full Arduino + Processing tutorial to get the setup.

    Processing
    Download the oscP5 processing library and put it in your Processing sketch folder in the folder libraries.

    Initialize oscP5 library and broadcast data to port 12000. The port Unity will listen to.
    Add the remote location to listen to on port 3200. If Unity would broadcast event in this example, the broadcast port would be set to 3200. Initialise Arduino to be used later on.

    oscP5 = new OscP5(this,12000);
      myRemoteLocation = new NetAddress("127.0.0.1",3200);
      arduino = new Arduino(this, Arduino.list()[0], 57600);

    In the draw function we read the analoge pin 0 to get sensor values from the Flexi Force sensor. Set the OSC message to flexiforce. Unity will listen to this label. Add the message of the sensor value into the osc message with add method. This method can take numbers, strings and byte data.

    float flexiforceSensor = arduino.analogRead(0);
    OscMessage oscMess = new OscMessage("/flexiforce");
    oscMess.add(flexiforceSensor);

    oscP5.send(oscMess, myRemoteLocation);

    The entire Processing sketch can be seen here.

    Unity
    In Unity you can import the Osc.cs and UDPPacketIO.cs to broadcast and listen to UDP data.

    Set up the corresponding host and ports in your Unity script.

    public var OSCHost : String = "127.0.0.1";
    public var SendToPort : int = 3200;
    public var ListenerPort : int = 12000;

    Import the UDPPacketIO and Osc components and feed in the host and ports. Add your specific label of your osc message and what method to call when receiving this event from Processing.

    var udp : UDPPacketIO = GetComponent("UDPPacketIO");
    udp.init(OSCHost, SendToPort, ListenerPort);
           
    handler = GetComponent("Osc");
    handler.init(udp);
    handler.SetAddressHandler("/flexiforce", AffectObject);

    In the receiving method you can print out the label and message values. In this case the sensor value from the Flexi Force. The cube will change width when getting a new value from Processing.

    public function AffectObject(oscMessage : OscMessage) : void
    {      
            Debug.Log("Event name: " + Osc.OscMessageToString(oscMessage));
            Debug.Log("Event data: " + oscMessage.Values[0]);
           
            var myCube = GameObject.Find("Cube");
            var boxWidth:int = 8 - ( oscMessage.Values[0]);
            myCube.transform.localScale = Vector3(boxWidth,5,5);
    }

    • between0and1 19:58 on August 6, 2012 Permalink

      HI, I really like the tutorial and am excited to make it work full through. I’ve got all the processing / arduino bits working, but on moving into Unity I get a null reference exception on the line
      udp.init(-args-)

      I’m assuming it has to do with the way it is trying to access UDPPacketIO script, but I don’t yet have enough experience to know how to modify this to work properly.
      I’ve downloaded your processing demo and worked on it from there, but still can’t quite get it.

      Thanks for the demo! I’m excited to move forward wit this

    • Ellen 07:42 on September 6, 2012 Permalink

      @between0and1 Which platform are you on? If you run WIndows you need to change a line UDPPacketIO.cs. On Mac you import IO like this: “using System.IO;”. On Windows you need to add .Ports so you import ” System.IO.Ports;”

  • Arduino library for LED Message Display

    Ellen 18:53 on April 15, 2012 | 5 Permalink | Reply
    Tags: , Arduino library, , LED

    Making life a lot easier I wrote an Arduino library that takes care of converting strings and calculating the checksum of all commands sent to the LED Message Display. Compared to the first example of sending text to the display the library can send commands of how long the text should display, how to be animated in and out and display European characters. All included in the BockiMessageBoard library on Github.

    amplus_led_message_display_sundh

    The code below shows how to initiate and send messages:

    #include <BockiMessageBoard.h>

    BockiMessageBoard messageBoard = BockiMessageBoard(0); // 0 is the Id of your message board

    void setup {
          // Configure the display before sending the text.
          int displayTime = 0.5; // Input 0.5 sec or 1 to 25 seconds
          messageBoard.configure(displayTime,SCROLLLEFT,VERTICALCLOSE);
    }

    void loop {
          String euroChars = "Testing with European characters <U45><U44><U76><U65><U64><U61>";
          messageBoard.displayMessage(PAGE_A,euroChars);
    }

    The library generate serial data to the LED Message Display with this setup:

    <ID00><L1><PA><FE><MA><WC><FD>MESSAGE CHECKSUM<E>

    <ID00> - The id of the message board.
    <L1> - Line number
    <PA> - Page id
    <FE> - How the text will appear. Scrolling, twinkeling, snowing…
    <MA> -
    <WC> - Waiting time. How long to display text.
    <FD> - How the text will disappear. Scrolling, twinkeling, snowing…
    MESSAGE - The message text to be displayed
    CHECKSUM - Hex value calculated on all tag sabove.
    <E> - End of data.

    The circuit uses a RJ14 cable to transfer the serial data to the display board:

      Dear Ellen:
      Loved this project ! CONGRATULATIONS.
      I wonder how did you get the communication protocol?
      It happened to me having a couple of identical Displays with different protocols, all of the from China same format and features.
      Can you share with me the protocol of this particular Display?
      Thank you so much.
      Cheers.

      1- can i define where the message i sent it will appear in the led display ?
      2- can i show two different message in the same time ?
      3- can i use it like LCD arduino libirary ( first set cursor then print message and clear it when i need )
      4- if you have video for this project after implementation can you send to me
      Thanks :)
