I can't find the problem of a crash (no error when compiling
Posted: Tue Feb 26, 2008 6:22 pm
I have tried some examples(code snippets). If I compile it doesn't give any errors. But when I play it it crashes.
When I use the debugger from Visual C++
it returns that it's crash on
camera->setTarget(tris_node->getAbsolutePosition()+vector3df(0,120-lastMousePos.Y,0));
