There is a method Game::send_player_build_waterway(int32_t, Path&) that works just like for roads.
Waterways have a special placement rule: They can go along any edge which is located between two water triangles. They can therefore reach all fields with MOVECAPS_SWIM plus some other fields. Always use a CheckStepFerry when checking ferry or waterway paths. -- https://code.launchpad.net/~widelands-dev/widelands/ferry/+merge/351880 Your team Widelands Developers is subscribed to branch lp:~widelands-dev/widelands/ferry. _______________________________________________ Mailing list: https://launchpad.net/~widelands-dev Post to : widelands-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~widelands-dev More help : https://help.launchpad.net/ListHelp
