Game Engine Framework? :: Resource Manager

The ResourceManager maintains the extension-point entries for "!IndieZen::!ResourceManager::ResourceService". It can also be used as a class factory for I_ResourceServices.

Example Code Snippet

This code snippet was taken from the MMORPG Base Client implementation found here.

It can be used as an example of how to get a specific resource service by name.

Currently reserved names are:

• ogre - ResourceService required by the Ogre rendering library
• torque - ResourceService required by the Torque Game Engine
• nvidia - ResourceService required by the NVidia SDK
• team - Resource Service required by IndieZen Game Studio for replicating resource modifications.

void
BaseClient::initResourceService()
{
    // TODO Don't hard-code this
    std::string resourceServiceType("ogre");

    m_pResourceService = 
        ResourceManager::I_ResourceManager.instance().getService(resourceServiceType);

}
