在../qtOgitor/src/mainwindowactions.cpp中定义了void MainWindow::newScene()
在Qtogitor的新建场景按钮激活后调用
1: void MainWindow::newScene() 2: { 3: const char NewSceneDefinition[] = " <OBJECT typename=/"%s/" scenemanagertype=/"%s/" name=/"SceneManager/"> <PROPERTY id=/"configfile/" type=/"7/" value=/"%s/"></PROPERTY></OBJECT>/n" 4: "</OGITORSCENE>/n"; 5: 6: Ogitors::OgitorsRoot *ogRoot = OgitorsRoot::getSingletonPtr(); 7: 8: if(ogRoot->IsSceneLoaded()) 9: mOgreWidget->setSwitchingScene(true); 10: 11: if(!(ogRoot->TerminateScene())) 12: { 13: mOgreWidget->setSwitchingScene(false); 14: return; 15: } 16: 17: Ogitors::PROJECTOPTIONS *pOpt = ogRoot->GetProjectOptions(); 18: 19: pOpt->IsNewProject = true; 20: pOpt->ProjectName = ""; 21: pOpt->ProjectDir = Ogitors::OgitorsSystem::getSingletonPtr()->getProjectsDirectory(); 22: pOpt->SceneManagerName = "OctreeSceneManager"; 23: pOpt->TerrainDirectory = "Terrain"; 24: pOpt->HydraxDirectory = "Hydrax"; 25: pOpt->CaelumDirectory = "Caelum"; 26: pOpt->PagedGeometryDirectory = "PagedGeometry"; 27: pOpt->SceneManagerConfigFile = ""; 28: pOpt->CameraSaveCount = 0; 29: pOpt->CameraSpeed = 1.0f; 30: pOpt->ResourceDirectories.clear(); 31: pOpt->SelectionRectColour = Ogre::ColourValue(0.5f, 0, 1); 32: pOpt->SelectionBBColour = Ogre::ColourValue(1, 1, 1); 33: pOpt->HighlightBBColour = Ogre::ColourValue(0.91f, 0.19f, 0.19f); 34: pOpt->SelectHighlightBBColour = Ogre::ColourValue(0.19f, 0.91f, 0.19f); 35: pOpt->ObjectCount = 0; 36: 37: for(unsigned int v = 0;v < 31;v++) 38: { 39: pOpt->LayerNames[v] = "Layer " + Ogre::StringConverter::toString(v); 40: pOpt->LayerVisible[v] = true; 41: } 42: 43: pOpt->LayerCount = 1; 44: 45: SettingsDialog dlg(QApplication::activeWindow(), pOpt); 46: 47: if(dlg.exec() == QDialog::Accepted) 48: { 49: char buffer[5000]; 50: Ogre::String filename = ogRoot->GetProjectOptions()->ProjectDir + "/" + ogRoot->GetProjectOptions()->ProjectName + ".ogscene"; 51: filename = Ogitors::OgitorsUtils::QualifyPath(filename); 52: 53: bool succeed = false; 54: 55: try 56: { 57: std::ofstream outfile(filename.c_str()); 58: 59: if(outfile.is_open()) 60: succeed = true; 61: 62: if(succeed) 63: { 64: outfile << "<?xml version=/"1.0/" encoding=/"utf-8/"?>/n"; 65: outfile << "<OGITORSCENE version=/"2/">/n"; 66: ogRoot->WriteProjectOptions(outfile,true); 67: sprintf_s(buffer,5000,NewSceneDefinition,ogRoot->GetProjectOptions()->SceneManagerName.c_str(),ogRoot->GetProjectOptions()->SceneManagerName.c_str(),ogRoot->GetProjectOptions()->SceneManagerConfigFile.c_str()); 68: outfile << buffer; 69: } 70: 71: outfile.close(); 72: } 73: catch(...) 74: { 75: succeed = false; 76: } 77: 78: if(!succeed) 79: { 80: OgitorsSystem::getSingletonPtr()->DisplayMessageDialog("The path is Read-Only. Ogitor can not work with Read-Only Project Paths!", DLGTYPE_OK); 81: return; 82: } 83: 84: ogRoot->LoadScene(filename); 85: } 86: updateRecentFiles(); 87: }void MainWindow::newScene()调用后会将初始场景写入xml格式的.ogscene文件中 请看上面62行代码
其中在66行代码调用的ogRoot->WriteProjectOptions(outfile,true);是将project的options更详细的写入文件
在D:/OgreSDK/ogitor_src/src0_43/Ogitor/src/OgitorsRootUtilityFunctions.cpp文件中定义了
