◆ apply_cmresult_to_city()

void apply_cmresult_to_city	(	struct city *	pcity,
		const std::unique_ptr< cm_result > &	cmr
	)

Rearrange workers according to a cm_result struct.

The caller must make sure that the result is valid.

◆ check_city_migrations()

bool check_city_migrations ( )

Check for citizens who want to migrate between the cities that overlap.

Migrants go to the city with higher score, if the growth of the target city is not blocked due to a missing improvement.

The following setting are used:

'game.server.mgr_turninterval' controls the number of turns between migration checks for one city (counted from the founding). If this setting is zero, or it is the first turn (T1), migration does no occur.

'game.server.mgr_distance' is the maximal distance for migration.

'game.server.mgr_nationchance' gives the chance for migration within one nation.

'game.server.mgr_worldchance' gives the chance for migration between all nations.

Returns TRUE iff there has been INTERNATIONAL migration.
