multiple cpp files.

[cassius]

Hi

 

At the moment the c++ files I am using are

 

main.cpp

app.cpp

app.h

The listing is getting a bit long now and I want to move all my functions into their own file called functions.cpp which will have its own header file (functions.h)

I am not sure where to put the include directive for this new file so that it is visible to all other files.

Should I just put it in main.cpp.....or what????

#ifndef _FILE_NAME_H_

#define _FILE_NAME_H_

 

/* code */

 

#endif

 

 

Shouldn't you learn the language and how to use the compiler *before* trying to write games with it?

I just use #pragma once at the top of each header file. Never had a problem with this on any compiler.

 

To add a new CPP file in your project, you should include the header from App.h and also drag the CPP file into the project explorer panel to add it to the project. Note that this has to be done separately for Xcode, Visual Studio, and Eclipse. (Eclipse requires that you modify the makefile to add the CPP file into the build chain.)

Just as a side note to structure. If you think your function count is high because you're putting them all into main or app, then that's not going to change if you put them into functions.cpp. It would seem to be you are programming more in C than C++ (that's fine) so if I were you I would start grouping functionality of functions and put them into their own source/header files so things are a little more structured.

 

I always just use VS to create my files (I use classes though where 1 source/header is 1 class). Josh has main & app files in a different directory (because they are shared between all platforms) then where your files will be created. This means if you want to include things between his files and yours you have to find them in your include.

 

So, make your functions.cpp/functions.h (although it's sort of a bad strategy) from VS. Then in app.h do: #include "../Projects/Windows/Functions.h" (going off memory on the paths there, but it's something like that).

Sorry, you should include files from App.h, in the "Source" directory, to include all your includes from. Main.cpp varies depending on platform. Android uses a special version of it, so App.h is the one to use.

Yes I am programming more in c than c++ cos that's what I know best. So far its working well. I know how to add files to visual c++project . I am using windows. I just need to know where to put include directives I could try trial and error methods but its quicker and safer to ask..

Thanks everybody.

EDIT: got it working
