CCSpriteFrameCache + CCTextureCache addImage Bug

Bug #2877 [Closed]

funkata 2013-10-02 19:06 . Updated almost 9 years ago

When using CCSpriteFrameCache addSpriteFramesWithFile and CCTextureCache addImage method, pre existing texture can be corrupted.

How to reproduce this bug:
1. Create a new project in cocos2d-x (I confirmed this bug exist in 2.1.5 and 2.2, don’t know about version < 2.1.5)
2. Make a simple generated PVR file (test.plist and test.pvr) using texture packer (in this case I generate the test.pvr using the cocos2d-x HelloWorld.png)
3. Add that files (test.plist and test.pvr) to the resource.
4. In the HelloWorldScene.cpp, in the init() method, comment all other code and make it like this

bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !CCLayer::init() )
    {
        return false;
    }
    CCTexture2D::PVRImagesHavePremultipliedAlpha(true);
    CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("test.plist");
    return true;
}

After that, run the project in the simulator, and you will notice that the fps texture is corrupted.

It’s not only PVR files that affected but also pvr.ccz files.

Same bug for me (Sorry for my english). I am programing a game. Everything is fine except the Release version in iOS. Somebody said changing the Project->BuildSetting->Optimization Level would be okay. But nothing fixed after I changed the build setting & clean the products & rebuild the release version. After a few days debug (God! 2 days more!). I found the problem, here is the code:
CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("test.plist");
Adding a plist file to the CCSpriteFrameCache, it failed!, But when I execute the same code twice, it work!
CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("test.plist"); CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("test.plist");
Getting inside of the addSpriteFramesWithFile() fun, target line
CCTexture2D *pTexture = CCTextureCache::sharedTextureCache()->addImage(texturePath.c_str());
pTexture is null first time and not null second time.
This bug only happen in pvr format (also pvr.ccz). Please anyone tell me how to fix the problem!

I encounter this problem, too!
cocos2d-x 2.1.5&2.2.3
And I suspect this problem also makes CCArmature display incorrect with PVR images!

I've solved the problem that CCArmature display incorrect with PVR images.
TexturePacker must check the "Premultiply Alpha" option, and cpp must add line:

CCTexture2D::PVRImagesHavePremultipliedAlpha(true);

But FPS is still corrupted as @funkata said!
