Freeciv is written in C. Header files should be compatible with C++ so

tiles, i.e. the distance from 'ptile0' to 'ptile1', only using cardinal

In Freeciv, we have the general concept of a "position" or "tile". A tile

can be referred to in any of several coordinate systems. The distinction

becomes important when we start to use non-standard maps (see above).

Players (more aptly named, 'civilizations'), exist in games. Except in
|

|
the context of a running game, the entity makes no sense. Players and
|
||
|
their status are part of savefiles. A game can be saved and restarted
|
||
|
on a different server; the players will be the same. A new game will

on a different server; the players will be the same. A new game will

have new players. Players exist in common/ (even games do) but a
|
||
|
client only has one instantiated player.

Also, name patch files descriptively (e.g. "fix-foo-bug-0.patch" is good,
|
||
|
but "freeciv.patch" is not).
|

|
- When doing a "diff" for a patch, be sure to exclude unnecessary files
|
||
|
by using the "-X" argument to "diff". E.g.:
