ai_fuzzy()

bool ai_fuzzy	(	const struct player *	pplayer,
		bool	normal_decision
	)

Return the value normal_decision (a boolean), except if the AI is fuzzy, then sometimes flip the value.

The intention of this is that instead of if (condition) { action } you can use if (ai_fuzzy(pplayer, condition)) { action } to sometimes flip a decision, to simulate an AI with some confusion, indecisiveness, forgetfulness etc. In practice its often safer to use if (condition && ai_fuzzy(pplayer,1)) { action } for an action which only makes sense if condition holds, but which a fuzzy AI can safely "forget". Note that for a non-fuzzy AI, or for a human player being helped by the AI (eg, autosettlers), you can ignore the "ai_fuzzy(pplayer," part, and read the previous example as: if (condition && 1) { action } –dwp

ai_level_help()

char* ai_level_help

(

const char *

cmdname

)

Helper function for skill level command help.

'cmdname' is a server command name. Caller must free returned string.

expansionism_of_skill_level()

static int expansionism_of_skill_level ( enum ai_level  level )

static

Return the AI expansion tendency, a percentage factor to value new cities, compared to defaults.

0 means never build new cities, > 100 means to (over?)value them even more than the default (already expansionistic) AI.
