6a1670dbc31cc0e44178bbd9ad34ff0d5981a060 "Migrate to STL containers/algorithms."
has replaced core::map<T, bool> with std::set<T>, but didn't update
the accompanying comment saying "value is dummy". This happened at
two places.
/*
List of active objects that the client knows of.
- Value is dummy.
*/
std::set<u16> m_known_objects;
- A block is cleared from here when client says it has
deleted it from it's memory
- Key is position, value is dummy.
+ List of block positions.
No MapBlock* is stored here because the blocks can get deleted.
*/
std::set<v3s16> m_blocks_sent;
