Re: [rules-users] best way to write this rule?

The "or more" is essential. I can imagine that certain things need to be
done more than
once. Is that so?
Within the game there are:
- a list of potential badges that a player could earn
- with a set of things to do to earn each badge (what I'm considering the
rules)
Notice that the definition of a badge and how to earn it is very similar to
what has
to be recorded for a player's progress.
It is certainly possible to write a rule for each badge to determine whether
a player
has achieved it. But it could be much simpler if all achievements are
tallied individually,
because then rules just need to check for each badge whether a player's
achievements
match the badge's requirements; this can be done with a single rule.

In short I don't want to have to go through each thing each player has
done and try and determine which rule to run, I just want to pass in:
- their set of badges (with steps they've completed so far)
- what badges are available to earn (to match against)
- what they just did
Maybe I'm thinking about this the wrong way and there's an easier way
to do this. Still trying to figure the best implementation of the rule
and rule set. My goal is to load all the rules at load time (and
reload when I add a new badge) so that I have a full knowledgebase and
can just run it whenever someone does something in the game.
