When compiling I get: mapview_common.c: In function `put_one_tile': mapview_common.c:1073: warning: implicit declaration of function `game_find_city_by_xy_pos' i.e. there is a missing #include "game.h" in that file. Be sure to compile with --enable-debug so the compile stops on such warnings. ;) Your patch appears to work, but the approach is not very good, for two reasons. First is that it is very inefficient; you are iterating over all the player's cities every time that 'if' condition in put_one_tile is met. As the game progresses and the player knows about more cities and reveals more of the map it will get slower and slower. Generally, the drawing code is the bottleneck in freeciv (at least on the client side), so we do not want to make it slower. (Incidentally, why not just pass the tile pointer instead of int x, y? The tile pointer uniquely identifies the tile so checking ptile == pcity->tile should have the same effect as the code in your patch.) Secondly, conceptually tile_city and your game_find_city_by_xy_pos should always return the same result, that is the whole point of keeping the city pointer in the tile struct. The fact that something like your function would be needed means that there is a problem somewhere else, perhaps in the client's updating of this field, or the server's sending of it. So this issue needs more investigating. :( ---------------------------------------------------------------------- 安心して。私は世界的に有名な刑事と知り合いだ。 _______________________________________________ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev
