Hi,

I have a error using sdkbox facebook plugin. I installed it as described on documentation page : http://docs.sdkbox.com/en/plugins/facebook/v3-cpp/
It was successfully installed automatically. But I also checked it according to instruction for manual installation. all steps are OK. Building is also OK. cocos version is cocos2d-x-3.13 . target android version is 23. minSdkVersion is 11. Android version on device is 5.0.

While calling sdkbox::PluginFacebook::init(); there is "JNI DETECTED ERROR IN APPLICATION: JNI GetObjectClass called with pending exception 'com.facebook.FacebookException' thrown in unknown throw location" error.

Could somebody help me please with this isuue ?
Thank you.

I was wondering if there is any favorite or nice tool for design scenarios.
Which tools are your favorite for designing levels?
- note: changing size and positions by code (try and error) is not a good solution

I would like to start a new game project, a platform game, but I would like to let the designer have complete control over the scenarios, (and avoid as much as possible the need of a developer)

I need something that can visualize and order:
* (LONG scenarios)
* NOT tiled.

extras:
* maybe 2 or + layers of deep
* if its possible to handle distorted sprites

I searched a bit and found that there is a limitation on the size of tilemaps around 128x128 because of an openGL limitation on the amount of vertices that can be rendered in one call.

I am using the experimental::TMXTiledMap, which only renders the tiles visible in the viewport (automatic culling). It does so by calculating which tiles are visible and creating an index buffer with only the visible vertices. This index buffer is a vector of GLushort (16bit).

I changed the source code of experimental::TMXLayer like this:

CCFastTMXLayer.h
std::vector<GLuint> _indices; instead of std::vector<GLushort> _indices;

CCFastTMXLayer.cpp in the method updateIndexBuffer()
_indexBuffer = IndexBuffer::create(IndexBuffer::IndexType::INDEX_TYPE_SHORT_32, (int)_indices.size());
instead of
_indexBuffer = IndexBuffer::create(IndexBuffer::IndexType::INDEX_TYPE_SHORT_16, (int)_indices.size());

After this change, cocos could render maps bigger than 128x128 on win32.

My question: why is this limit enforced hard coded? Because of multi-platform? I googled a bit, and found out it should work on iOS as well (not tested):

on which someone answers:

This answer is incorrect, GL_UNSIGNED_INT is supported for glDrawElements if GL_OES_element_index_uint is implemented (which it is in iOS, according to OpenGLES/ES2/glext.h).

	}

This part doesnt work;
((activeGameObject*)nodeB)->getDamage(1); //(*)
((activeGameObject*)nodeA)->getDamage(1); //(*)
if health of real activeGameObject is 10, health of this objects is -1 always for all objects. And health of real objects doesnt decreases, but health of this objects (*) decreases.

both this pointers:
((activeGameObject*)nodeB)
((activeGameObject*)nodeA)
and pointer to real actriveGameObject point to different areas of memory.

How to make it work right??Help please.

Hello guys.

I developed android game using cocos2d-x lua.
And now I want make it to iOs version.
In android, I used the lua source code which is compiled in luajit.
by the way, when I compiled it in iOs, then precompilation error occur.
I think it is because of arm64 don't allow luajit in xcode.
Is there any way to use luajit in xcode arm64?

Hello everyone.
I have successfully integrated SDKBOX Play. Set up leaderboard in both itunesconnect and Google Developer console. And everything works fine. The thing i don't understand is how getPlayerCenteredScores work? When I set number_of_entries to 1, it returns current player, and when i call it with any number other than 1 it returns all entries.

What i want to do is, I want to get top 10 scores and add player to last. Is this the right way to do it? If not, how can i do it?

I didn't found solution for this neither in google nor in this forum. So whar I did wrong? Or what should I do to fix this?

I use android-ndk-r12b, abi android-19 and Cocos 3.13.1.
