K 10 svn:author V 3 jjm K 8 svn:date V 27 2000-04-25T12:00:53.000000Z K 7 svn:log V 1984 Fixes bugs in the recent code which allows ocean to be changed into land. Continent information was not being updated: - Adds check_terrain_ocean_land_change() to unitfunc.c to handle side-effects. - Calls check_terrain_ocean_land_change() from all three of the Mining, Irrigation and Transforming sections of update_unit_activity(). - Adds a new clause to the "if" statement in handle_tile_info() in packhand.c so that climap_update_continents() is called whenever ocean is changed into land. The terrain ruleset allows for changing land into ocean -- but the code didn't handle this case correctly. The gamelog map becomes out of date whenever ocean is changed into land (or vice-versa): - Makes sure the new check_terrain_ocean_land_change() can handle changing land into ocean. - Changes can_unit_do_activity_targeted() to not allow changing the land on which a city sits into ocean. - Changes map_mine_tile(), map_irrigate_tile() and map_transform_tile() to clear all infrastructure when changing from land to ocean. - Adds a new case in handle_tile_info() that recomputes the client's continents whenever land is changed into ocean. - Makes a small change to climap_update_continents() which allows it to work in the case where the tile "known" flags are set, but the tile "continent" values are not (it should not affect normal operation). This allows a simple implementation of the previous change. - Adds gamelog() calls to the new check_terrain_ocean_land_change() function. - Does a klugey thing in gamelog() itself (we should fix the gamelog format and open/close semantics someday...). - Finally, to make use of all this, changes default/terrain.ruleset to allow Transforming Swamp into Ocean (was Swamp->Plains; may still do Swamp->Forest->Plains (and it's faster!)), and Mining Forest into Swamp. Finally: - Fixes an unrelated bug in the ACTIVITY_MINE case of can_unit_do_activity_targeted(). Bug reported by Cameron Morland . END
