Triangle Selector

[JustMax]

Hi

I have a problem with the Triangle Selectors. Every time I try to create one its simply empty. Have I misunderstood or forget something?

Code: Select all

        IAnimatedMesh* mesh = drivers->smgr->getMesh("models/fighter/fighter.3DS");

        IAnimatedMeshSceneNode* node = drivers->smgr->addAnimatedMeshSceneNode( mesh , 0, id);

        ITriangleSelector* s = drivers->smgr->createTriangleSelector(mesh, node);
        node->setTriangleSelector(s);

#ifdef FULLDEBUGINFO
        GameLog("%i    %i",drivers->smgr->getMeshManipulator()->getPolyCount(mesh),
                      s->getTriangleCount()); //output:"468    0"
#endif

        allUnitTriangeles->addTriangleSelector(s);
        s->drop();

This should be all the relevant source code.

Instead of this:

Code: Select all

ITriangleSelector* s = drivers->smgr->createTriangleSelector(mesh, node); 

I'd suggest getting an explicit IMesh* from your IAnimatedMesh* like this:

Code: Select all

ITriangleSelector* s = drivers->smgr->createTriangleSelector(mesh->getMesh(0), node);

big thanks it works now.

n/p. IAnimatedMesh has been changed to be derived from IMesh. It wasn't always that way, and the behaviour when you pass an IAnimatedMesh* as an IMesh* isn't what you might expect. This is catching a lot of people out.
