Be careful when dealing with C++ floating point.

Look at this piece of code: Vector3 colPlaneNor; float dx = abs(aabb1->getPosition().x() – aabb2->getPosition().x()); float dy = abs(aabb1->getPosition().y() – aabb2->getPosition().y()); if(dx < (aabb1->_width + obb2->_width)/2.0f)     colPlaneNor = Vector3::UNIT_Y; else if(dy < (aabb1->_height + aabb2->_height)/2.0f)     colPlaneNor = Vector3::UNIT_X; The idea of these lines of code is to determine the collision plane normal when two …
