Correct usage of dynamic ManualObject

[gavrus]

Im trying to use Ogre::ManualObject in dynamic manner:

Code: Select all

Ogre::ManualObject* mo = mSceneMgr->createManualObje("Name");
mo->setDynamic(true);

mo->begin("Material");
        mo->position(...);
        mo->normal(...);
        mo->position(...);
        mo->normal(...);
        ....
        mo->index(...);
        ....
 mo->end();

Ogre::SceneNode* tileNode = mSceneMgr->getRootSceneNode()->createChildSceneNode()->attachObject(mo);

..........

//Trying to change section

mo->beginUpdate(0);
        mo->position(...);
        mo->normal(...);
        mo->position(...);
        mo->normal(...);
        ....
        mo->index(...);
        ....
 mo->end(); //This line produces SEGFAULT

As you can see, line mo->end() produces SEGFAULT, but when i try to beginUpdate() end() whith empty body, all works fine - content of ManualObject`s section "dissapears". What im doing wrong? Why SEGFAULT occurs?

Solved)
It was must to call beginUpdate() end() inside FrameListener callback:

Code: Select all

bool FrameListener::frameRenderingQueued(const Ogre::FrameEvent &evt)
{
    manualObject->beginUpdate();
    ....
    manualObject->end();
}
