+# Reconquering Empyre
+
+## About
+This is a (shoddy written) python3 port of [VMS Empire](http://www.catb.org/~esr/vms-empire/) using ncurses. This is my 1st big project (the other one is relatively small), so there is going to be a lot of SNAFU and stuff.
+
+## Requirements
+* Python 3
+* noise
+
+
+### Startup parameters
+* `-f [1,2,3,4]` Determine the Fog of War
+  * 1: See the full map and all the units.
+  * 2: See the full map but only friendly units
+  * 3 (default): Map is unexplored but once discovered all units will remain visible.
+  * 4: Map is unexplored and the only units visible are units within visual range of friendly units
+* `-m xxx/yyy` Map size for horizontal and vertical axis from 60-999. Defaults are 100x50
+* `-d delay` This option controls the length of time the computer will delay after printing informational messages at the top of the screen. delay is specified in seconds. The default value is 2 which allows the user two seconds to read a message.
+
+
+### Keys
+Depending on the context the following keys issue the following commands. There are the following contexts:
+* `global` Commands that work no matter the context
+* `city` Commands that work with cities
+* `unit` Commands that work with units
+
+#### Global
+* `l` Display the logs
+* `g` Give the AI 1 turn
+* `n` Give the AI x turns
+* `q` Save and Quit
+
+#### City
+* `p` Pause, do nothing
+* `b` Build a unit
+  * `a` army
+  * `f` fighter
+  * `p` patrol boat
+  * `d` destroyer
+  * `s` submarine
+  * `t` troop transport
+  * `c` aircraft carrier
+  * `b` battleship
+  * `z` satellite
+
+#### Unit
+* `Num 12346789` Direction to move/attack/load a unit
+* `u` Unload a unit from Transport or Carrier
+* `s` Turn unit into a sentry for 10 rounds
+* `w` Set a waypoint for units to move to
+
+
+## Notes
+
+### Combat
+
+```    while (att_obj->hits > 0 && def_obj->hits > 0) {
+        if (irand (2) == 0) /* defender hits? */
+            att_obj->hits -= piece_attr[def_obj->type].strength;
+        else def_obj->hits -= piece_attr[att_obj->type].strength;
+    }
+```
+
+|Piece|You|Enemy|Moves|Hits|Str|Cost|
+| --- | ---| ---| ---| ---| ---| ---|
+|Army|A|a|1|1|1|5(6)|
+|Fighter|F|f|8|1|1|10(12)|
+|Patrol Boat|P|p|4|1|1|15(18)|
+|Destroyer|D|d|2|3|1|20(24)|
+|Submarine|S|s|2|2|3|20(24)|
+|Troop Transport|T|t|2|1|1|30(36)|
+|Aircraft Carrier|C|c|2|8|1|30(36)|
+|Battleship|B|b|2|10|2|40(48)|
+|Satellite|Z|z|10|--|--|50(60)|

+typedef struct piece_attr {
+        char sname; /* eg 'C' */
+        char name[20]; /* eg "aircraft carrier" */
+        char nickname[20]; /* eg "carrier" */
+        char article[20]; /* eg "an aircraft carrier" */
+        char plural[20]; /* eg "aircraft carriers" */
+        char terrain[4]; /* terrain piece can pass over eg "." */
+        uchar build_time; /* time needed to build unit */
+        uchar strength; /* attack strength */
+        uchar max_hits; /* number of hits when completely repaired */
+        uchar speed; /* number of squares moved per turn */
+        uchar capacity; /* max objects that can be held */
+        long range; /* range of piece */
+} piece_attr_t;
+```
+
+### Gamestate format
+The `gamestate` is a variable that tells the program the state of the game. It is updated constantly and through the [Pickle](https://docs.python.org/3/library/pickle.html) to store the game to a file. I should make it save as a JSON at some point in case people want to create programs other than python to play from savegames.
+
+#### gamestate['metadata']
+This contains metadata about the game, what parameters was used to feed the Perlin Noise generator, size of the map, rounds etc
+* width - width of the map
+* height - height of the map
+* coast_percentage - the percentage of cities that are coastal cities
+* scale
+* base
+* octaves
+* persistence
+* lucnarity
+* xoffset
+* yoffset
+* turn - who's turn it is, either AI or player
+* round - int
+
+#### gamestate['terrain']
+This contains the blueprint of the terrain. It is a two dimensional array with either the one of the following values:
+* `l` Land
+* `w` Water
+* `c` City
+
+#### gamestate['coast']
+A list of positions that are costs. Used for city placement. May be useful later on.
+
+#### gamestate['cities']
+List of cities, per city it stores the following:
+* `location` x/y coordinate
+* `side` Either `player` or `ai`
+* `order` What its building or doing
+* `stage` How far it is doing this
+
+#### gamestate['units']
+List of units, per unit it stores the following:
+* `type` The unit-type, army, fighter etc
+* `side` Either `player` or `ai`
+* `location` x/y coordinate
+* `order` Standing order for the units (`sentry`, `waypoint`)
+* `stage` a counter or x/y coordinate
+* `moves` How many moves are left
+* `hits` How many hits are left
+
+#### gamestate['fog']
+A map with the Fog of War. Not sure about what has been explored or what is still fog.
