create_barbarian_player()

struct player* create_barbarian_player

(

enum barbarian_type

type

)

Creates the land/sea barbarian player and inits some stuff.

If barbarian player already exists, return player pointer. If barbarians are dead, revive them with a new leader :-)

Dead barbarians forget the map and lose the money.

summon_barbarians()

void summon_barbarians

(

Summon barbarians out of the blue.

Try more times for more difficult levels - which means there can be more than one uprising in one year!

try_summon_barbarians()

static void try_summon_barbarians ( )

static

The barbarians are summoned at a randomly chosen place if:

1. It's not closer than MIN_UNREST_DIST and not further than MAX_UNREST_DIST from the nearest city. City owner is called 'victim' here.
2. The place or a neighbouring tile must be empty to deploy the units.
3. If it's the sea it shouldn't be far from the land. (questionable)
4. Place must be known to the victim
5. The uprising chance depends also on the victim empire size, its government (civil_war_chance) and barbarian difficulty level.
6. The number of land units also depends slightly on victim's empire size and barbarian difficulty level. Q: The empire size is used so there are no uprisings in the beginning of the game (year is not good as it can be customized), but it seems a bit unjust if someone is always small. So maybe it should rather be an average number of cities (all cities/player num)? Depending on the victim government type is also questionable.

unleash_barbarians()

bool unleash_barbarians

(

struct tile *

ptile

)

Unleash barbarians means give barbarian player some units and move them out of the hut, unless there's no place to go.

Barbarian unit deployment algorithm: If enough free land around, deploy on land, if not enough land but some sea free, load some of them on boats, otherwise (not much land and no sea) kill enemy unit and stay in a village. The return value indicates if the explorer survived entering the vilage.
