Hello there. Since version 3.8.1 I found that the folder cocos2d-console inside tools directory is always empty.
In the previous version I used (3.4) this path contains the bin directory with the cocos command line executable. If you try to download and unzip this package you can see that these files are properly here, but they aren't in the folowing releases.

The cocos command-line tool guide suggest to add the path \tools\cocos2d-console\bin to PATH env. var, so how it's possible this folder is empty? How to get the command line tools when downloading a new cocos version?

When I download a new version I already try to run download-deps.py and setup.py but this doesnt' the trick

i just follow this tutorial

every thing goes well ,i can load the store and make the purchase.

but then i found out that

in the InAppPurchaseManager.m

it send out a notification after finished the success transation.

[[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerTransactionSucceededNotification object:self userInfo:userInfo];

normally with objective-c i can observe the notification and then give the purchased items to player by this :

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(purchaseSuccess:) name:kInAppPurchaseManagerTransactionSucceededNotification object: nil];

but with c++, how can i do the same . it seems CCNotificationCenter of cocos2d-x can't not observe the notification send by NSNotificationCenter.

so how can i get the information that the purchase has been successfully done?

i'm actually a 2d artist..and new to programming...

just, anybody can help me with details. thanks a lot~

So I have a game Cocos2d-x game written in C++. The majority of the game engine is decoupled from the framework which I compile as a separate library and linked in to the cocos2d-x app. I've been exploring the possibility of making a web build and I couldn't find much on this topic. What I'm thinking of doing is to rewrite all the code coupled to Cocos2d-x in Javascript, and somehow load the decoupled c++ game engine library so I wouldn't have to rewrite the whole engine in Javascript. Is this possible or is there another way?

Just to mention I'm not willing to compile the engine to JS using something like emscripten because I don't want to expose the engine code. Thanks!

Hello,

I'm an independent artist building children story apps for cocos2d-x. Currently we're only on IOS, and I want to use the apple thinning feature but my programmer is having a hard time making it to work.

We have a combination of png, pvr.czz, jons and jpegs assets.

Apple thinning is a very important feature to us. If it is not supported by cocos2d-x that would suck, and unfortunately we would have to move and try something different.

Any help or guidance would be greatly appreciated.

Thanks,

Ivan

Hi guys,

Could the AudioEngine be improved by adding a method to get the audio duration using the url apart from the audio's id?
Currently to get the audio duration, its needed to play it to get the id and then with that id the duration we can obtained.
The current approach has some problems.
Many times users need know the audio duration to prepare a sequence of actions where some of them depends on an audio finish. Right now this cannot be done.
Also the current implementation does not works fine because doing play in a line and getting the duration on the next line, returns always .-1 due to the async approach of new audio engine. After call play, the sound wont be loaded for some frames and calling getDuration intermediately will fail. The drawback of the async load method could not be a problem if a preloading service will be available. So when the play is called the sound is available just on that frame and getDuration would work. Even thought there is a preloading implementation it seems its not working always.
In any case this wont help when only is needed to get the audio duration to create a sequence of actions.

So my humble suggestions are:
1) Add a method to get the audio duration using the sound's url. This will allow not to play the sound.
2) Making the preloading mechanism work for audio assets.

Thank you all.

About Point one, I was debugging a bit it looks like there is a bug,
When on the audioEngine's preload callback, a sound is played and then the getDuration is called,
the result is -1 even thought the audio is already loaded. The problem is on AudioEngine-win32.cpp
because player.audioCache->duration has the right duration but player._ready is false. so always -1
is returned.

float AudioEngineImpl::getDuration(int audioID)
{
auto& player = _audioPlayers[audioID];
if(player._ready){
return player.audioCache->duration;
} else {
return AudioEngine::TIME_UNKNOWN;
}
}

The issue is that when I comment the line with the joint it works, but when I let it uncommented I get black screen or crash.

Does anybody see an issue?

Do I need to clear memory temporary dummy sprite?

Sprite *dummySprite = Sprite::create("filepath.png");
Use it for calculating some dimensions.
someParentSprite->SetContentSize("...using dummy sprite to calculate...");

delete dummySprite;
dummySprite = NULL

App crashes if I delete this dummySprite.

As per C++ the pointers creates memory in heap which means, we need to manually free the memory. I understand that sprite is autorelease object but I always take this in the context that if a parent is deleted from the scene/layer or the sprite itself is removed then it frees its memory by itself. But never knew if it autoreleases even if it goes out of scope.

Am I correct that I won't have to use explicitly delete dummySprite ?

PS: I am using dummySprite for setting content size of parent. Otherwise, it's not beings added in parent.

I checked the cpptests and blur effect is there. But I am not able to understand exactly how it is used to apply effect on the sprite. I've never used shaders before and I want to apply blur effect to layer.

Looks like blur shader isn't already there in the cocos2d-x but in cpptests, it's creating the blur shader and then using it somehow.

Is there anything like..

EffectBlur *eb = EffectBlur::create(blurRadius, .....);
node->applyEffect(eb);

or every shader is created from scratch?

Thanks
