Bounty of 50USD for volume support on Win32?

cocos2d-x C++
#1

I would pay $50 for a working implementation of these methods for Win32.

SimpleAudioEngine.h

// properties
/**
@brief The volume of the background music max value is 1.0,the min value is 0.0
@js getMusicVolume
*/
float getBackgroundMusicVolume();

/**
@brief set the volume of background music
@param volume must be in 0.0~1.0
@js setMusicVolume
*/
void setBackgroundMusicVolume(float volume);

/**
@brief The volume of the effects max value is 1.0,the min value is 0.0
*/
float getEffectsVolume();

/**
@brief set the volume of sound effecs
@param volume must be in 0.0~1.0
*/
void setEffectsVolume(float volume);

Hi Cory,

Let me ask the dev team why these don’t work.

#3

I have tried patching the MCI Player but haven’t been able to get it to work.

Thanks for the reply. I am getting some negative reviews on Steam due to our inability to provide volume control on Windows.

#4

SimpleAudioEngine has some bugs on Windows, but i am not sure if all the functions you mentioned can not work.

We implement new audio engine in v3.3, will you try it?

#5

From looking at this document:

http://www.cocos2d-x.org/programmersguide/13/

it appears that SimpleAudioEngine is still the primary interface.

However, in the case of v3.3 the methods

 SimpleAudioEngine::getEffectsVolume()

and

 SimpleAudioEngine::setEffectsVolume(float volume)

are both stub methods. I see that AudioEngineImpl has some code for volume support. I don’t know what AudioEngineImpl is, but if that’s the new audio engine and SimpleAudioEngine is depreciated I don’t know.

I would really like to figure this out for v2.x … I saw this blog post

That seems to include support for volume code using MciPlayer, however, I could not get that implementation to work.

I’ll send the $50 via PayPal =)

Hi @zhangxm does the new Audio engine work for all platforms we support? If so, I’ll update Chapter 13 to use the new Audio Engine.

#7

I am still very interested in any Windows implementation of SimpleAudioEngine’s volume settings and the MciPlayer backend.

#8

No. Now it can work on all platforms except wp8, wp8.1, winrt8.1 and linux. We will write the document after we finish it.

#9

New audio engine can work on windows. It is powerful then SimpleAudioEngine.

#10

Can it work with Cocos2d-x v2.x?
