std::pair< map_location, map_location > choose_move(std::vector< target > &targets)
A config object defines a single node in a WML file, with access to child nodes.
Definition: config.hpp:159
A small explanation about what's going on here: Each action has access to two game_info objects First...
Definition: actions.cpp:61
std::multimap< map_location, map_location > move_map
The standard way in which a map of possible moves is recorded.
Definition: game_info.hpp:43
candidate action framework
Encapsulates the map of the game.
Definition: location.hpp:38
Structure which holds a single route between one location and another.
