 Before a Urho3D application can enter its main loop, the Engine subsystem object must be created and initialized by calling its \ref Engine::Initialize "Initialize()" function. Parameters sent in a VariantMap can be used to direct how the Engine initializes itself and the subsystems. One way to configure the parameters is to parse them from the command line like the Urho3DPlayer application does: this is accomplished by the helper function \ref Engine::ParseParameters "ParseParameters()".

 - ResourcePrefixPaths (string) A semicolon-separated list of resource prefix paths to use. If not specified then the default prefix path is set to executable path. The resource prefix paths can also be defined using URHO3D_PREFIX_PATH env-var. When both are defined, the paths set by -pp takes higher precedence.
