Hi,
can you help me with tankSwitch->setSingleChildOn(0,0); function, i cannot
build it:
Code:
int main()
{
// Declare a group for the root of our tree and three groups to contain
individual tank models
osg::Group* root = new osg::Group();
osg::Group* tankOneGroup = NULL;
// Load the models from the same file
tankOneGroup = dynamic_cast<osg::Group*>
(osgDB::readNodeFile("t72-tank_des.flt"));
// add the first tank as a child of the root node
root->addChild(tankOneGroup);
// Declare an instance of 'findNodeVisitor' class and set its
searchForName string equal to "sw1"
findNodeVisitor findNode("sw1");
// Initiate traversal of this findNodeVisitor instance starting
// from tankTwoGroup, searching all its children. Build a list of nodes
whose names matched the searchForName string above.
tankOneGroup->accept(findNode);
// Declare a switch type and assign it to the first node in our list of
matching nodes.
osgSim::MultiSwitch* tankSwitch = NULL;
tankSwitch = dynamic_cast <osgSim::MultiSwitch*> (findNode.getFirst());
// make sure it's a valid handle. If it is, set the first (only)
multi-switch: assuming a single switch set
// with values {1, 0}, activeSwitchSet 0
if (tankSwitch)
{
int nc=0;
nc=tankSwitch->getNumChildren();
tankSwitch->setSingleChildOn(0,0); // good model
//tankSwitch->setSingleChildOn(0,1); // bad model
}
osgViewer::Viewer viewer;
viewer.setSceneData( root );
viewer.realize();
return viewer.run();
}
output text:
main.obj : error LNK2001: unresolved external symbol "__declspec(dllimport)
public: bool __thiscall osgSim::MultiSwitch::setSingleChildOn(unsigned
int,unsigned int)" (__imp_?setsinglechil...@multiswitch@osgSim@@qae_...@z)
1>D:\programovani\vc\osg\osgtest\Debug\osgtest.exe : fatal error LNK1120: 1
unresolved externals
Where is the problem?
I can build it when the function is behind "//"
//tankSwitch->setSingleChildOn(0,0); // good model
OpenSceneGraph Library 2.8.2
Microsoft visual studio 2008 9.0.2 ...8RTM
NetFramework 3.5 SP1
Thank you!
Cheers,
petr
