The first error is related a function not being declared. http://msdn.microsoft.com/en-us/library/yha416c7(VS.80).aspx Take a look at the example osgtext, I am guessing the correct line of code is osgText::Text not text(), I don't like using namespaces it makes the code hard to read :)

Hi guys, I'm new to OpenSceneGraph, I'm doing a Uni course and I need some help. Here's my code. Code: #include <iostream> #include <ctime> #include <cstdlib> #include <osg/Group> #include <osg/Geode> #include <osg/Geometry> #include <osg/ShapeDrawable> #include <osg/MatrixTransform> #include <osgViewer/Viewer> #include <osg/Texture2D> #include <osgDB/ReadFile> #include <osgText/Font> #include <osgText/Text> using namespace std; using namespace osg; using namespace osgViewer; using namespace osgDB; using namespace osgText; class PlanetCallback : public osg::NodeCallback { public: PlanetCallback() { angle = 0.0; } virtual void operator()( osg::Node* node, osg::NodeVisitor* nv ) { // Normally, check to make sure we have an update // visitor, not necessary in this simple example. osg::MatrixTransform* mt = dynamic_cast<osg::MatrixTransform*>( node ); osg::Matrix mR, mT; // Move the planet away from the sun mT.makeTranslate(Vec3(4, 0, 0)); mR.makeRotate(angle, Vec3(0, 0, 1)); mt->setMatrix( mT * mR ); angle=angle+0.001; // Continue traversing so that OSG can process // any other nodes with callbacks. traverse( node, nv ); } private: double angle; }; int main() { srand((unsigned)time(0)); // the viewer Viewer *viewer=new Viewer(); // the root node osg::Group *root=new Group(); // the planets const int NUM=9; Geode *geode[NUM]; Sphere *sphere[NUM]; ShapeDrawable *draw[NUM]; MatrixTransform *rot[NUM]; // setup the planets for(int k=0;k<NUM;k++) { geode[k]=new Geode(); sphere[k]=new Sphere(Vec3(k,0,0),0.4); draw[k]=new ShapeDrawable(sphere[k]); draw[k]->setColor(Vec4(1,0,0,1)); geode[k]->addDrawable(draw[k]); //add texture //Texture2D *tex=new Texture2D(); //Image*image=readImageFile("C:/Mars.jpg"); //tex->setImage(image); //StateSet* state=draw[k]->getOrCreateStateSet(); //state->setTextureAttributeAndModes(0,tex,StateAttribute::ON); //geode[k]->addDrawable(draw[k]); // rotate the sphere(s) rot[k]=new MatrixTransform(); rot[k]->setUpdateCallback(new PlanetCallback()); rot[k]->addChild(geode[k]); root->addChild(rot[k]); } //add test Text *textX=new text(); textX->setText('Hello, this is a project about planets moving around the sun"); textX->setPosition (Vec3 (1.1,0,0)); textX->setCharacterSize(0.2); textX->setColor (Vec4(1,0,0,1)); sxsgeode->addDrawable(textX); textX->setAxisAlignment(Text::VZ_PLANE); // add the sun Geode *geodeSun = new Geode(); Sphere *sphereSun = new Sphere(Vec3(0,0,0),1); ShapeDrawable * drawSun = new ShapeDrawable(sphereSun); drawSun->setColor(Vec4(1, 1, 0, 1)); geodeSun->addDrawable(drawSun); root->addChild(geodeSun); viewer->setSceneData(root); viewer->setUpViewInWindow(100,100,512,512); viewer->run(); } Here are the errors. > 1>------ Build started: Project: Planets, Configuration: Release Win32 ------ > 1>Compiling... > 1>MainThread.cpp > 1>.\MainThread.cpp(104) : error C2061: syntax error : identifier 'text' > 1>.\MainThread.cpp(105) : error C2001: newline in constant > 1>.\MainThread.cpp(105) : error C2015: too many characters in constant > 1>.\MainThread.cpp(106) : error C2146: syntax error : missing ')' before identifier 'textX' > 1>.\MainThread.cpp(109) : error C2065: 'sxsgeode' : undeclared identifier > 1>.\MainThread.cpp(109) : error C2227: left of '->addDrawable' must point to class/struct/union/generic type > 1> type is ''unknown-type'' > 1>.\MainThread.cpp(110) : error C2039: 'VZ_PLANE' : is not a member of 'osgText::Text' > 1> C:\Users\J\Desktop\OpenSceneGraph-2.8.2\include\osgText/Text(27) : see declaration of 'osgText::Text' > 1>.\MainThread.cpp(110) : error C2065: 'VZ_PLANE' : undeclared identifier > 1>Build log was saved at "file://c:\Users\J\Desktop\Planets\Planets\Release\BuildLog.htm" > 1>Planets - 8 error(s), 0 warning(s) > ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== I also have 4 questions please. 1. I can't get textures working to make the circles look like the 9 planets, how do I do this? 2. How can I get 5 planets to go the way they're going now, and 4 planets to go the other way? 3. How can I add names to make the planets. 4. How can I do a space like background, not just the blue one I have now? Thanks all. (Please Note: I'm basically a 1st grader on my first day at school, so please try and use simple English). ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=27579#27579 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
