Unsuccessful PC Attempt by Ron Newcomb begins here.

"Will run the Unsuccessful Attempt By rules for all characters, including the player. Also silences the library messages printed by the built-in Check rules."

Silent checks is a truth state that varies. Silent checks is usually true.

This is the modified check stage rule:
    anonymously consider the specific check rulebook;
    if [that] rule succeeded, [this] rule succeeds; [if a check rule succeeds, it ends action processing but does not call the Unsuccessful Attempt By rules. We mimic that here because it's useful: we can write a Check rule to both say a one-liner and end the action in a single line, and, we can still tell Unsuccessful Attempt to narrate a failed action without needing to ensure a one-line was said by checking The Reason The Action Failed against a list of rules that have one-liners. ]
    if the rule failed begin;
        if the actor is the player, consider the unsuccessful attempt by rules; [ ..will be called for NPCs from the usual place]
        rule fails;
    end if.

To anonymously consider (R - a rule): (- anon_consider({R}); -).

Include (-
[ anon_consider R;
    @push untouchable_silence;
    untouchable_silence = (+ silent checks +); ! checked by L__M() and related library functions
    if (reason_the_action_failed = ProcessRulebook(R)) ! this sets, then tests, that variable
    {
        if (RulebookSucceeded()) ActRulebookSucceeds(reason_the_action_failed);
        else ActRulebookFails(reason_the_action_failed);
    }
    @pull untouchable_silence;
];
-).

The modified check stage rule is listed instead of the check stage rule in the specific action-processing rules.

Unsuccessful PC Attempt ends here.
