get a list of all available Textures?

[johnhpus]

I'm trying to get a list of all of the textures in the Media/Materials/Texture folder. I had thought that this code would give me the names of those textures.

Code: Select all

	std::vector<std::string> getAllTextureNames()
	{
		std::vector<std::string> vecTextureNames;
		Ogre::TextureManager::ResourceMapIterator iter = Ogre::TextureManager::getSingleton().getResourceIterator();
		while( iter.hasMoreElements() )
		{
			Ogre::ResourcePtr rptr = iter.peekNextValue();
			vecTextureNames.push_back( rptr.get()->getName() );
			iter.moveNext();
		}
		return vecTextureNames;
	}

But this doesn't seem to work right. It gives me some textures but far from all. I wonder if maybe this code is only listing the textures that have been loaded by Ogre so far? I use something very similar for listing Material names and it works fine.

Ok. It seems that yeah, they're not listed untill they're loaded. I think it must be this way for the GpuManager as well. So does Ogre provide the list I'm looking for somewhere or is it just up to me to make a list?

You could use something along these lines, using the FileSystem class:

Code: Select all

	
FileSystemArchive fileSystem("../Media", "FileSystem");
fileSystem.load();
StringVectorPtr files = fileSystem.find("*.tga", false);

for (StringVector::iterator i = files->begin(); i != files->end(); ++i)
{                  
    String fullName = *i;
    ....

}
