I am new to Drools and I've been trying to figure this out through the
user guide and examples I've been finding, but I'm not sure what the
best way is to write this rule (or set of rules).
What I'm trying to write is a set of rules for determining when
someone has earned (or is starting to earn) a badge. I want to be able
to show their progress on badge completion as well as when they
finally complete said badge.
I'm passing in the following to the rule:
- Player
- Earned Badges (list)
- All possible badges
The first rule only deals with one specific badge. So I have something
like this in my when:
$badge : Badge(name == "Something") //my assumption is that Badge
comes from the list of all possible badges I've just passed in
Then, I decided to split the rule into two. One rule for when they had
not earned it yet:
and I call a function
function earnedBadge(List<EarnedBadge> badges, String name) {
boolean found = false;
for(EarnedBadge badge : badges) {
if(badge.getBadge().getName().equals(name)) {
found = true;
}
}
return found;
}
when:
earnedBadge(badges, $badge (name))
Then I got stuck. If they have completed one or more tasks I would
like to create (or use the badge they've started to earn) to track
their progress. So, If I have 5 possible things they need to do and
they've done three of those I'd like to create a new EarnedBadge for
the one they are earning and give it a percentage of 60%. What would
be the best way to do something like this?
Thanks for helping out the newbie, it's greatly appreciated :).

You are thinking too procedurally.
You shouldn't be using lists, or collections within the rules, instead generally the
thing within the list should be inserted into the working memory.
Rather than having the function you can then right something like the following:
//person has earned the badge
p : Person()
badge : EarnedBadge(owner == p, name == "Foo")
or
//person has not earned the badge
p : Person()
not EarnedBadge(owner == p, name == "Foo")
For getting their progress you'd probably keep a list of BadgeTasks that a person has
completed,
You'd then use count/accumulate to add up the progress and update the EarnedBadge.

I've been playing around with this further but I'm still running into
issues. I guess here's the crux of the matter:
As a player I have:
- a list of badges I am in progress of completing
- something I've just done that could go towards one or more of these badges
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)
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.
Thank you for any help, it is much appreciated.

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.
