Hi guys,

I search an simple example for use fmod.dll in an DarkGDK project.

Someone test it ?

It will work fine - the Shadow Of Th Beast (or Bouncing Lines demo) on my website (in the DBPro section) uses either FMOD or BASS.

Both work fine.

I used to use FMOD with Ogre before I moved to Dark GDK... I'm not really sure how to implement it into Dark GDK, but I'll experiment tonight and let you know tomorrow

Its quite simple - you have two ways :

A) Include the .lib file and copy the DLL to where the executable is
B) Use LoadLibrary to load the DLL and directly access the functions.

I know c language, but not Vc++ 2008.

How can include .lib file ? I add fmodapi375winapilib in the VC++ Directories for library files and fmodapi375winapiinc in the VC++ Dir for Include Files.

After, i wrote this code :



I have this error :



i forget something it's sure ... but what ?... someone help please ?

FMOD comes in two styles - an interface for C and one for C++

Here is an example of how to call the routines using the C system (taken from my FightTune game) :

Thx for this ...

Before, i would like to know why my source doesn't work ... i have a problem with the lib i think ...

Someone can help me for this ??

Osx:I'm sure your source help me after .. when i solve my lib problem.

fmod works fine with dgdk, just as it does with anything else. its a seperate system and doesnt need "implementing with" gdk or anything, just use it as you would in any other app.

download FMOD Ex as usual. Install it. Open vc2008. open your project. goto the Tools menu then click Options. On the expandable list on the left of the options expand Projects and Solutions and then select VC++ Directories.

On the drop down box under the text "Show directories for:" change it to show "Include files". Then add a new folder by pressing the icon with a picture of a yellow folder. Click the "..." button on the right of the new entry that has appeared in the list and browse to where the fmod header is. If you have installed to the default path that is:

C:\Program Files\FMOD SoundSystem\FMOD Programmers API Win32\api\inc

Then, again on the drop down box that is under "Show directories for:" change it now to "Library files". Add a new entry as before and set it to the library directory. If you installed in the default place then that will be:

C:\Program Files\FMOD SoundSystem\FMOD Programmers API Win32\api\lib

Now press ok to set these options. Now open up your PROJECT options by right clicking on the name of your project in the solution explorer and then clicking Properties. Expand the Linker options and then click on "Input". In the box to the right of "Additional Dependencies" add "fmodex_vc.lib" WITHOUT the quotes.

Finally, browse to the Api folder of the fmod install using windows explorer which by default if you installed to the default place will be:

C:\Program Files\FMOD SoundSystem\FMOD Programmers API Win32\api

and copy fmodex.dll into the folder on your hard drive that contains your project source files and hopefully you should now be able to use the fmod api fully and without error!

See the fmod documentations for getting started tutorials on actually coding with fmod

Hope that helps.

Works fine now !... thx a lot ...

I can play with fmod .. ^^ ... i'm going to make an old school demo with this ... ^^

Thx for your good explain Sephnroth ...
