Cocos2d-X Adding subfolders to Classes folder throws errors

Question

I am working on a Cocos2D-X project. I am trying to organize my code files into sub-folders inside the Classes folder. The Classes folder is being shared for both iOS and Android. If I just leave the code files in the Classes folder everything works fine but if I place them into sub-folders I get all types of errors. I've linked the sub-folders in my Project Properties and even added the sub-folders in the Android.mk file but no luck.

I've been Googling/Reading articles and everywhere it keeps saying that you have to keep all classes in the root 'Classes folder'. FOr small projects that might not be an issue but as the project gets bigger it will become a nightmare having to always run through one folder full of all the code files.

Could someone please advise if there is a way to organize .h/.cpp files into sub-folders in Cocos2D-X project.

Answer 1

If you add sub-folders, you should also add them to the #include directives.

For example, if your directory is like this:

+ Classes/
| + HomeScreen/
| | - HomeScreen.cpp
| | - HomeScreen.h
| + GameScreen/
| | - GameScreen.cpp
| | - HomeScreen.h

Your #includes should look like:

#include "HomeScreen/HomeScreen.h"
#include "GameScreen/GameScreen.h"

Of course, without knowing the actual errors, we can't provide a definite solution. This is just one of the most common errors I've seen.

Answer 2

XCode can automatically add such subfolders to include search paths. But for android, you should update Android.mk manually (OK, we've done it by automatic parsing *.xcodeproj and generating Android.mk, but it's a bit complicated solution).

 LOCAL_C_INCLUDES :=  \
 $(LOCAL_PATH)/../ \
 $(LOCAL_PATH)/../GameScreen \
 $(LOCAL_PATH)/../HomeScreen

Answer 3

Right click the classes folder in x-code and add a new group, then drag the headers/code into it that you want to organize instead of creating subfolders outside of xcode and dragging/dropping them into the classes folder.
