* To load an attached resource pack file, you must declare the pack with :

* getResourcePack_pack_name(ResourceMap &map)

* RESOURCE_PACK(shaders) // declaring the resource pack function
* Resource::ResourceMap myShaders; // defining a resource map
* Resource::getResourcePack(myShaders); // putting the resources of the resource pack in the map
* string *shader = new string(myShaders["shaders/shaderFile.glsl"]); // getting a resource file
