is_req_knowable()

static bool is_req_knowable ( const struct player *  pov_player, const struct req_context *  context, const struct player *  other_player, const struct requirement *  req, const enum req_problem_type  prob_type  )

static

Is an evaluation of the requirement accurate when pov_player evaluates it?

context may be NULL. This is equivalent to passing an empty context.

TODO: Move the data to a data file. That will

• let non programmers help complete it and/or fix what is wrong
• let clients not written in C use the data
