◆ civil_war()

struct player * civil_war ( struct player * pplayer )

Capturing a nation's primary capital is a devastating blow. This function creates a new AI player, and randomly splits the original players city list into two. Of course this results in a real mix up of territory - but since when have civil wars ever been tidy, or civil.

Embassies: All embassies with other players are lost. Other players retain their embassies with pplayer. Units: Units inside cities are assigned to the new owner of the city. Units outside are transferred along with the ownership of their supporting city. If the units are in a unit stack with non rebel units, then whichever units are nearest an allied city are teleported to that city. If the stack is a transport at sea, then all rebel units on the transport are teleported to their nearest allied city.

Cities: Are split randomly into 2. This results in a real mix up of teritory - but since when have civil wars ever been tidy, or for any matter civil?

One caveat, since the spliting of cities is random, you can conceive that this could result in either the original player or the rebel getting 0 cities. To prevent this, the hack below ensures that each side gets roughly half, which ones is still determined randomly.

◆ civil_war_possible()

bool civil_war_possible	(	struct player *	pplayer,
		bool	conquering_city,
		bool	honour_server_option
	)

Check if civil war is possible for a player. If conquering_city is TRUE, one of the cities currently in the empire will shortly not be and shouldn't be considered. honour_server_option controls whether we honour the 'civilwarsize' server option. (If we don't, we still enforce a minimum empire size, to avoid the risk of creating a new player with no cities.)

Referenced by api_edit_civil_war(), unit_conquer_city(), and unit_do_destroy_city().

◆ civil_war_triggered()

bool civil_war_triggered ( struct player * pplayer )

civil_war_triggered: The capture of a primary capital is not a sure fire way to throw and empire into civil war. Some governments are more susceptible than others, here are the base probabilities: Anarchy 90% Despotism 80% Monarchy 70% Fundamentalism 60% (Only in civ2 ruleset) Communism 50% Republic 40% Democracy 30% In addition each city in disorder adds and each celebrating city subtracts from the probability of a civil war. If you have at least 1 turns notice of the impending loss of your capital, you can hike luxuries up to the highest value, and by this reduce the chance of a civil war. In fact by hiking the luxuries to 100% under Democracy, it is easy to get massively negative numbers - guaranteeing imunity from civil war. Likewise, 3 cities in disorder under despotism guarantees a civil war. This routine calculates these probabilities and returns true if a civil war is triggered.

◆ pick_a_nation()

struct nation_type * pick_a_nation	(	const struct nation_list *	choices,
		bool	ignore_conflicts,
		bool	needs_startpos,
		enum barbarian_type	barb_type
	)

This function returns a random-ish nation that is suitable for 'barb_type' and is usable (not already in use by an existing player, and if needs_startpos is set, would not be prohibited from starting on the map by the current scenario – NB this doesn't check that any start position is actually free).

Unless 'ignore_conflicts' is set, this function tries hard to avoid a nation marked as "conflicting with" one already in the game. A conflicting nation will be returned only if the alternative is to return NO_NATION_SELECTED. Such a return indicates that there are no remaining nations which match the above criteria.

If 'choices' is non-NULL, nations from the supplied list are preferred; but if there are no (non-conflicting) nations on the list that match the criteria, one will be chosen from outside the list (as if the list had not been supplied).

All other things being equal, prefers to pick a nation which returns a high score from nations_match() relative to any nations already in the game.

Send all players if src is NULL; send to all connections if dest is NULL.

This function also sends the diplstate of the player. So take care, that all players are defined in the client and in the server. To create a player without sending the diplstate, use send_player_info_c().

void send_player_diplstate_c	(	struct player *	src,

Identical to send_player_info_c(), but sends the diplstate of the player.

This function solves one problem of using an extra packet for the diplstate. It can only be send if the player exists at the destination. Thus, this function should be called after the player(s) exists on both sides of the connection.
