Question

std::vector<Ogre::SceneNode*>::iterator itr;
for(itr=mSelectedObjects.begin();itr!=mSelectedObjects.end();itr++){
    itr->showBoundingBox(true); //here
}

I’m getting “expression must have pointer-to-class type” on the marked line, and I’m not sure why. Can anyone help?

Answer 1

Replace the erroneous line with:

(*itr)->showBoundingBox(true); //here

Since you’re storing pointers, you need to dereference itr twice to get from the iterator to the object (once for the iterator and once for the pointer).
