New plugin code editor and external lib

vvvv beta question
#1

Hello
I’d like to know if it’s easy to work with external c# lib with the new code editor …
I’d like to make a plugin to work with irrklang who is a soundengine for game,
there is a c# version of the lib . First i’d like to know if it’s possible to work directly in the code editor , and second what the best way to go , i think i need help for the start to have the basic hello world working , then i can probably manage to continue doing it myself.
I have quicly try to include file and dll in the folder of the plugin , but i’m still not exeprienced enough with c# to make it work.
I’m especially interrested in 3d sound engine with multichannel capabilities.

here is a first exemple of the api:
C#

using System;
using IrrKlang;

namespace HelloWorld
{
  class Example
  {
   [STAThread](STAThread)
   static void Main(string[]() args)
   {
     // start up the engine
     ISoundEngine engine = new ISoundEngine();


     // play a sound file
     engine.play2D("../../media/ophelia.mp3");


     // wait until user presses ok to end application

     System.Windows.Forms.MessageBox.Show("Playing, press ok.");

   } // end main()

  } // end class

} // end namespace

hi sanch,
you’ll have to reference the irrklang assembly in your project file.
in order to do that i’d recommend doing the following:

  • add an environment variable called VVVV45 to your system pointing to your vvvv installation.
  • start vvvv, create your new plugin with ctrl+enter from template.
  • go to $(VVVVV45)/plugins/PLUGINNAME, create a new folder Dependencies and copy the irrklang assembly to that location.
  • open the project file (PLUGINNAME.csproj in vvvv/plugins/PLUGINNAME) with either an texteditor or a c# IDE (like sharpdevelop or visual studio) and add your irrklang assembly as reference to the project.
  • you can now either work with the codeeditor or if you need to debug your plugin you can work with your favorite IDE.

this was just for joreg , to show him the code looks bad with the code button… because he don’t believe me ;)

Hi , with the help of the vvvvdev i manage to have some sound outputed , now i got few other c# newbie problem …

So i manage to have the lib working but now i guess it’s more a c# progrmming problem , i want to make an array of sound object but didn’ t manage to make the right initialisation …
I got the following error :" 08:25:08 ERR : Object reference not set to an instance of an object"
any help apreciated

here is the plugin:

Ohhh forget about the last post i did research about c# array and managed it myself…

here is the last version.

It’s like the wave player node , but you got 3d positions in space , also you can play each sound many time it doesn’t stop the sound playing, just create a new one. You can loop , seek position , change speed , pause , change volume , change the distance from where you can hear the sound.
still need to add listenning position , dopler effect , effect , driver selection … but for that i need to create custom pin and to know a bit how it works … any help apreciated again…
thx

btw the update pin is not use atm…

what do you mean exactly by custom pin?

#9

well i’d like to create different node for the lib , like filestream > effect > engine …
so i guess i need to create some custom connection?
What is the best approch to do that?

#10

also how can i create differrent node who use the same object?

#11

here is a new version who should really work for you
You need to put the 3 irrklang dll from the plugin irrklang folder in the bin/managed/ folder
and a test file is in the plugin directori.

cool, looking forward to try this when i’m back home… :)

#13

Got an nice version with dopler effect
But the node start to be full of pin …
I added an small exemple with ex9 renderer of what can be done.
I would like to add all the effect and other option but thats just too much for one node…
sorry for the messy help patch …
if you use it don’t forget putting the 3 dll from irrklang folder into bin/managed/ folder

Couple of quick ones for you:

To output position:
replace:

Flength[i](i) = (FSounds[i](i).PlayLength)/1000;
FCurrentPos[i](i) = (FSounds[i](i).PlayPosition)/1000;

by:

Flength[i](i) = (FSounds[i](i).PlayLength)/1000.0;
FCurrentPos[i](i) = (FSounds[i](i).PlayPosition)/1000.0;

To have the decimals as well :)

Then to create your stream:

ISound sound = FEngine.Play3D(FFile[i](i),(float)FPos[i](i).x,(float)FPos[i](i).y,(float)FPos[i](i).z,FLoop[i](i));
if (sound != null)
{
  FSounds.Add(i,sound);
}
else
{
   //Do something to handle error here
}

As if your engine fails to create the sounds it returns ISound as null,
so you shouldnt add it in your dictionary (You can add ISpread FMessage you notify for example).
