示例1: sort
void
EditorLevel::save_level(Writer& fw)
{
// Sort the level before saving, so that object order doesn't change
// after a save/load cycle (load sort() too)
sort();
// Write header
fw.begin_object("pingus-level");
fw.write_int("version", 3);
fw.begin_mapping("head");
fw.write_string("license", "GPLv3+");
fw.write_string("levelname", impl->levelname);
fw.write_string("description", impl->description);
fw.write_string("author", impl->author);
fw.write_int("number-of-pingus", impl->number_of_pingus);
fw.write_int("number-to-save", impl->number_to_save);
fw.write_int("time", impl->time);
fw.write_string("music", impl->music);
// Write the list of actions to the file
fw.begin_mapping("actions");
for (auto i = impl->actions.begin(); i != impl->actions.end(); i++)
{
if (i->second > 0)
fw.write_int(i->first.c_str(), i->second);
}
fw.end_mapping(); // actions
fw.write_size("levelsize", impl->size);

// Write the objects
