Hi, I do not understand some code lines in exrdm example. It is located in the physics list , SelectPhysicsList() method.
1/ "if (!hadPhysicsList) delete hadPhysicsList;" . What is the purpose of deleting a NULL pointer ? We need to delete it if the corresponding object already exists, so that a new one can be created...Or do I miss something.....
2/ "if (!hadPhysicsList) delete emPhysicsList;". I get even more confused here. Why deleting emPhysicsList if hadPhysicsList is NULL ? Isn't it "if (emPhysicsList) delete emPhysicsList;"
