Are you using ref_pr<Node> for pointers to the Groups your are managing? If not there is you problem.

Hello all, I have a number of pointers to several osg::Groups that I am making children of a PositionAttitudeTransform by using replaceChild on the PAT. It works fine until I try to go back to the Group that started out as the initial child of the PAT, in which case the program crashes with a memory violation. Right now, I have to recreate the osg::Groups (actually pointers to osg::Groups) from scratch, and because I cann't delete a pointer to an osg::Group (error C2248: 'osg::Group::Group' : cannot access protected member declared in class 'osg::Group') I have a memory leak. Any ideas how to get replaceChild not to crash? Is there another way of doing this? Here's my code: //All tools are osg::Group* and toolTrans is a PAT* if (currentTool == tool1) nextTool = tool2; else if (currentTool == tool2) nextTool = tool3; else if (currentTool == tool3) nextTool = tool4; else if (currentTool == tool4) nextTool = tool1; toolTrans->replaceChild(dynamic_cast<osg::Node*> (currentTool), dynamic_cast<osg::Node*> (nextTool)); //CRASHES HERE ONLY WHEN GOING FROM tool4 to tool1. currentTool = nextTool; Thanks all. _________________________________________________________________ Play Q6 for your chance to WIN great prizes. http://q6trivia.imagine-live.com/enca/landing _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
