I keep getting this error when I try to compile my source:

Code: Select all

error C2352: 's2d::AudioData::LoadPCM' : illegal call of non-static member function

The code for that section is:

Code: Select all

   AudioPlayer::Init();
   Char* file = "bgmusic.pcm";
   s2d::AudioData* song = AudioData::LoadPCM(file);

What am I doing wrong?

you have to use an instance of the audio player, there is actually one made for you when using the GameEngine. But you can not instanciate a new instance directly from it. you first have to make a derived class.

like this for example (i'm using it).

GameEngine.h

Code: Select all

#ifndef GAMEENGINE_H
#define GAMEENGINE_H

#include "./s2d/s2d.h"

class GameEngine : public Engine
{
   public:
      GameEngine( void* userdata [] );
      ~GameEngine( void );
      result   Init( void );
      void   Free( void );
      void   Exec( void );
      void   Exec2( void );
      void   PreRender( void );
      void   Render( void );
      void   PostRender( void );
};

#endif


GameEngine.cpp

Code: Select all

#include "GameEngine.h"

GameEngine::GameEngine( void* userdata [] ): Engine( userdata )
{
}

GameEngine::~GameEngine( void )
{
}

result   GameEngine::Init( void )
{
   return S2D_OK;
}

void   GameEngine::Free( void )
{
}

void   GameEngine::Exec( void )
{
}

void   GameEngine::Exec2( void )
{
}

void   GameEngine::PreRender( void )
{
}

void   GameEngine::Render( void )
{
}

void   GameEngine::PostRender( void )
{
}


add these files to your project and in your main cpp file "include" it.

then to make audio work :

Code: Select all

//somewhere in your init code
//instance
AudioData* SomeSound = new AudioData();
//load a 16000khz, 16 bit signed mono raw pcm file (at least that's what i use and seems to work)
SomeSound ->LoadPCM(_LS("something.snd"));

//somewhere in your "game" loop
//Play the sound, g_pEng is an engine instance of the class above this. You can look up what the values are that are given here
g_pEng->m_pAudioPlayer->Play(SomeSound ,1,SomeSound ->GetSize(),255,false);

//When you quit your "game"
//at the end delete the some sound
SAFE_DELETE(SomeSound);


I had figured this out earlier today infact, such as silly mistake. Thanks for your help!
