This library allows games to blindly call a method that stores game state (as a bytearray) over and over in a data structure that handles moving between previous states (e.g. undo and redo buttons).
It uses the these APIs defined in game_api.h:
store_data(string key, byte[] data): write data (bytearray), referenced by key (string).byte[] read_stored_data(string key): read data stored at key.
It provides new APIs used by games (or Lua bindings):
int get_new_session_id(): meant to be called by a game at the beginning of a new game session. This ID is used to group saved states together.save_state(int session_id, byte[] state): games can call repeatedly every time the player makes a significant move. The library should automatically store the state in a data structure that makes it easy to access later.bool has_saved_state_offset(int session_id, int move_id_offset):byte[] adjust_saved_state_offset(int session_id, int move_id_offset)
