示例1: LoadResource

/**
*  @brief
*    Loads a resource which type has to be evaluated internally
*/
bool Application::LoadResource(const String &sFilename, const String &sType)
{
	bool bResult = false;	// Error by default

	// Clear the scene, after calling this method the scene is empty
	ClearScene();

	// Destroy the currently used script
	DestroyScript();

	// Backup the filename of the current resource
	m_sResourceFilename = sFilename;

	// Is there anything to load in?
	if (sFilename.GetLength()) {
		{ // Make the directory of the scene to load in to the current directory

			// Ok, the next thing is tricky, and every solution will end up in being a hack due to lack of information.
			// Within materials, meshes etc. there are usually relative paths provided, no absolute (not just true for PixelLight file formats).
			// Further, those paths are usually relative to a project root resulting e.g. within a default directory layout like
			// - Root
			//   - Data
			//     - Meshes
			//     - Materials
			// For "normal" projects this is no issue because everything is usually relative to the root project directory...
			// ... but this viewer must be able to pick out e.g. a mesh out of nowhere and must still be able to locate the required
			// other resources like materials. So, in here, we can only work with heuristics... this can and will of course go from
			// time to time horribly wrong...

			// First try: Find the first "Data" occurrence with the given filename and hope that it's the project root directory

			// Get filename as clean URL
			Url cUrl = Url(sFilename);
			cUrl.Collapse();

			// Get the first part of the path, and then look for "Data"
			uint32 nPathPos = 0;
			String sPart = cUrl.GetFirstPath(nPathPos);
			while (sPart != "Data" && sPart.GetLength())
				sPart = cUrl.GetNextPath(nPathPos);
			if (sPart == "Data") {
				// Set the base directory of the application
				SetBaseDirectory(cUrl.GetRoot() + cUrl.GetPath().GetSubstring(0, nPathPos - 5));	// -5 = Remove "Data/"
			} else {
				// Second try: Cut of "/Data/Scenes/" and hope that it's the project root directory.
				// If it's not there, take the directory the given resource is in.

				// Validate path
				const String sDirectory = cUrl.CutFilename();

				// Search for "/Data/Scenes/" and get the prefix of that, in case it's not there just use directly the scene directory
				const int nIndex = sDirectory.IndexOf("/Data/Scenes/");

				// Set the base directory of the application
				SetBaseDirectory("file://" + ((nIndex >= 0) ? sDirectory.GetSubstring(0, nIndex) : sDirectory) + '/');
			}
