The assertion is doing its job and telling you the issue a bad index ( also might be good to tell us which line of code is doing this, I'm assuming which one here ;) ) Will you always have 2 or more children ? as your code is removing child number 2 every time(indices are zero based), so if you have 2 children the second time around your code would fail due to there only being 1 child after one had been removed the first time etc... root->removeChild(root->getChildIndex((*ponto_itr)), 1); Should the 1 be 0? or the last child ? if the last then you need to do an int idx = root->getNumChildren() -1; and use that idx rather than 1 or 0 also for me I would be do something like the following, checking for valid pointers etc... osg::Group* root = (*ponto_itr)->getParent(0); if( root && root->getChildIndex((*ponto_itr)), 0)) root->removeChild(root->getChildIndex((*ponto_itr)), 0);

Hi, everyone. When testing my application, an error message appeared saying: 'Debug Assertion Failure' and 'vector subscription out of range'. This error occured when: 1) I wrote the following code: case(osgGA::GUIEventAdapter::KEYDOWN): { if(!ponto.empty()) // ponto is defined as: std::vector<Ponto*> ponto; in which Ponto is a class created by me. { for(ponto_itr = ponto.begin(); ponto_itr != ponto.end(); ponto_itr++) { if((*ponto_itr)->verifySelection()) // verifies if the shape associated with an instance of the class Ponto was picked { switch(ea.getKey()) { case(ea.KEY_Delete): { osg::Group* root = (*ponto_itr)->getParent(0); root->removeChild(root->getChildIndex((*ponto_itr)), 1); } } } } } 2) AND when I do the following: 1 - select one point; 2 - delete it; 3 - press delete again, having or NOT selected another 'ponto' (instance of class Ponto) on the screen. NOTE: when a drawable from 'ponto' is selected (picked), the 'ponto' is allocated in the vector. Thanks, Renan M Z Mendes
