Cocos2dx 2.2.4 and spine 1.9

mayank

We updated spine yesterday and started getting errors of various sorts :

Is spine 1.9 compatible with Cocos2dx 2.2.4 ( or does it needs cocos2dx 3.0 )
Is mesh feature available for cocos2dx 2.2.4 ? It seems to be giving unknown type "mesh" error

thanks,
Mayank

1.no need.I use 2.2.3 and just update spine to nearest version.You need change some code for spine which is now using some C++11 features.

mayank

@Captain .. can you please clarify what "change in code" I need to do

Nate

Yes to both questions. Maybe your compiler errors would help us determine the issue.

Thank Nate.

When I simply updated spine, and tried to use that skeleton, it gave error. But then I started to debug and found that "new spine" has this line in atlas file "Size 1024 340" . When I removed it, the spine worked fine. ( without any updating the libraries of anything )
For mesh it was still giving "Unknown attachment type mesh"

If mesh is supported in 2.2.4 ( note that I have not updated the libraries. I am using only the ones that come as downloaded with cocos-2dx-2.2.4 archive ), then please help me fix this error.

thanks,
Mayank

And on the details of error, when I follow the step shown at https://github.com/EsotericSoftware/spi ... cocos2dx/2

Specifically " Alternatively, the contents of the spine-c/src, spine-c/include and spine-cocos2dx/2/src directories can be copied into your project. Be sure your header search path will find the contents of the spine-c/include and spine-cocos2dx/2/src directories. Note that the includes use spine/Xxx.h, so the spine directory cannot be omitted when copying the files."

Then I start to get these errors :

my_game/proj.android.heroesvszombies/../../../extensions/spine/SkeletonAnimation.h:40:9: error: 'function' in namespace 'std' does not name a type
my_game/../../../extensions/spine/SkeletonAnimation.h:41:9: error: 'function' in namespace 'std' does not name a type
my_game/../../../extensions/spine/SkeletonAnimation.h:42:9: error: 'function' in namespace 'std' does not name a type

I think spine 1.9 should work fine with cocos2dx-2.2.4, as I'm using cocos2dx 2.2.2

In my memory, the cocos2d-x team modified the spine cocos2d-x runtime. so I just removed their code and add the latest runtime from github into my Xcode project.
One important thing you should do is: open the c++11 compile option.

Hi Kingbeful,

Thanks for reply and I am also getting to conclude that i need to set the c++11 compile option. Can you please guide me how you do it in cocos2dx

thanks,
Mayank

Also, one more thing...I read on some post that you need to rename the .c files to .cpp files in spine. Do I need to do it ?

kingbeful

My dev env is Xcode, and my steps are

1 create project using the python file:
./create_project.py -project MyGame -package com.MyCompany.AwesomeGame -language cpp

2 open the project in Xcode, and remove the spine folder in the Xcode.

3 comment the code //#include "spine/spine-cocos2dx.h" in extensions/cocos-ext.h in Xcode, as we don't need it

4 rename YOU_COCOS2DX_DIR/extensions/spine to YOU_COCOS2DX_DIR/extensions/spine_old to let your compiler not to search into it.

5 Add spine-c/include spine-c/src spine-cocos2dx/2/src/ to your project.

6 Add your header search path in Xcode(Assume they are under the Classes directory)
"$(SRCROOT)/../Classes/spine-c/include"
"$(SRCROOT)/../Classes/src"

7 Enable C++11 in your project
As your project using the cocos2dx project, the cocos2dx project also need to be ENABLED the c++11 feature

Hope it clear. You can try it.
Any questions, pls feel free to let me know.

Thanks kingbeful ! Its finally working for me for both Android and iOS

cheers,
