C++ question

[Raul]

In order to use correctly the boom, hdr, etc effects and to render the sbx file I saw I have to use the framewerk. Looking at Marleys Ghost post I used that code and everything is working fine, but I need to make some modification:

 

I have a class (cPlayer) which I have to make it use the fw object. Also from my Main.cpp I need to access it. Where do I have to define this line:

leadwerks::Framewerk fw;

If I declare it to the start of my Main.cpp when updating my player and accessing it I receive the

error C2065: 'fw' : undeclared identifier

error

 

What should I do?

You can make separate .h and .cpp file which has the global fw variable.

Two simple solutions are as follows:

 

declare fw as an extern in your player class header (not so nice)

 

pass it as a parameter to your player class constructor from your main routine

@Lumooja: I tried to add the leadwerks::Framewerk fw; into a separate .h file and to include the file in every class and main.cpp but I receive the message "fw already declared" (or something like that)

 

You said "global fw variable. " How to do that?

 

 

@Pixel Perfect:

How exactly can I pass it?

[Pixel Perfect]

// define a private member variable in your class

Framewerk* m_pFramewerk;

 

// pass a pointer to your framewerk object as a parameter to the constructor and assign it to the member variable

cPlayer::cplayer(Framework* pFramewerk)

{

m_pFramewerk= pFramewerk;

}

 

// Access the framewerk in your class via m_pFramewerk->

You need to add the extern keyword in the .h file.

 

// fwglobal.h
#pragma once
#include "framewerk.h"
extern leadwerks::Framewerk fw;

// fwglobal.cpp
#include "fwglobal.h"
leadwerks::Framewerk fw;

Thanks to both of you guys for sharing the code.
