Hi all,
I've successfully inherited ShadowMapViewport, overrided two methods
and made some changes here and there... all runs well without
problems.
Now I need to add a new TextureChunkPtr variable in my derived class.
Since I dont't need a fieldContainer I only added those few lines:
in header file:
TextureChunkPtr _finalSoftShadowTexture;
ImagePtr _finalSoftShadowImage;
===================================
in source file (constructors):
SoftShadowMapViewport::SoftShadowMapViewport(void) :
Inherited(),
_finalSoftShadowImage(NullFC),
_finalSoftShadowTexture(NullFC)
{
}
SoftShadowMapViewport::SoftShadowMapViewport(const
SoftShadowMapViewport &source) :
Inherited(source),
_finalSoftShadowImage(source._finalSoftShadowImage),
_finalSoftShadowTexture(source._finalSoftShadowTexture)
{
}
===================================
in source file (destructors):
void SoftShadowMapViewport::onDestroy(void)
{
subRefCP(_finalSoftShadowImage);
subRefCP(_finalSoftShadowTexture);
}
===================================
in source file (allocation):
_finalSoftShadowImage = Image::create();
addRefCP(_finalSoftShadowImage);
_finalSoftShadowTexture = TextureChunk::create();
addRefCP(_finalSoftShadowTexture);
This should be right, I think, but on exit it crashes in deleteContainers()
> OSGSystemD.dll!osg::FieldContainerPtrBase::deleteContainers() Riga
114 + 0xc C++
OSGSystemD.dll!osg::FieldContainerPtrBase::subRef() Riga 138 C++
OSGSystemD.dll!osg::subRefCP(const osg::FieldContainerPtrBase &
objectP={...}) Riga 88 C++
OSGSystemD.dll!osg::FieldContainerType::terminate() Riga 539 + 0xc
C++
OSGSystemD.dll!osg::FieldContainerType::~FieldContainerType() Riga 166
C++
Am I missing something?
I saw this comment in derived header:
// Variables should all be in SoftShadowMapViewportBase.
but I don't want a field container...
Any ideas?
Thank you very much,
