FMOD IMPLEMENTATION FOR BACKGROUND SOUND

Tutorial by Bob Lawrence:
This is just to get you started, many things can be done from here. Add more error checking and hardware detection support for instance (many more improvements/usage can be found in the doc’s). Also I am using the streaming as you can see, it loads faster. If you use pak files you will need to modify the calls fairly easily. This is setup to add a new Entity, but the code in FMOD.C can be pulled out and used internally to play the .ogg (or other supported files) very easily. I just thought I would make this an Entity to help people out understanding them also.

Good Luck! (Bob http://www.ourfun.com)
 

Get the fmodapi333.zip (http://www.fmod.org/)

Includes (add to your project path)

#include "fmod.h"
#include "fmod_errors.h" // optional

Global’s used in FMOD.h (just for your reference)

int FMODchannel = -1, FMODlength;
FSOUND_STREAM *FMODSample;

Libs (Add fmodvc.lib to your link settings, add fmod.dll to your program directory)

fmodvc.lib
fmod.dll

In GameMgr.c in GameMgr_FreeAllObjects add this:
FSOUND_Close(); //safety

In GameMgr_SetWorld add this around after // Create the coronas call:
//FMOD Background Sound
 if (!PlayFMOD_Spawn(GameMgr_GetWorld(GMgr)))
 GenVS_Error("GameMgr_SetWorld: FMODsound_Spawn failed.\n");

In Client.c add this at the end of the other includes:
#include "FMOD.h"

Then in CheckClientPlayerChanges add this near the top after assert(World);:
 
  if (!FSOUND_IsPlaying(FMODchannel))
 {
 
  FSOUND_Stream_Close(FMODSample);
  FSOUND_Close();

 }
 

Here is the FMOD.h file:

//**************
//FMOD Simple

#ifndef FMODsound_H
#define FMODsound_H

#ifdef __cplusplus
extern "C" {
#endif

#include "Genesis.h"

#pragma GE_Type("FMOD.bmp")

typedef struct FMODsound
{
    #pragma GE_Published

    char *TheFile;
    geVec3d Origin; // Where the entity is located

    #pragma GE_DefaultValue(TheFile, "spookywind.ogg")

} FMODsound;

geBoolean PlayFMOD_Spawn(geWorld *World);

int FMODchannel, FMODlength;
FSOUND_STREAM *FMODSample;
