The ScriptedInstance table has existed since the first migration and has always been empty: nothing wrote to it and nothing read it, so no time-space and no raid had a door. This adds the whole path — import the entrances, show them, describe them, build them, walk in, and take the rooms away again when the last player leaves.

WHERE THE DATA COMES FROM. The client files cannot answer this one: instance entrances are placed by the server, so there is no .dat to read. A packet capture can, and does, per map:

at 1234 132 79 108 2 0 0 0     <- the map that follows
wp 104 55 79 12 81 99          <- an entrance on it
gp 24 3 4996 8 0 0             <- a raid entrance

90 distinct time-space entrances and 14 raid entrances. The wp field layout is not guessed: NosCore.Packets already declares it as (X, Y, ScriptedInstanceId, PortalType, LevelMinimum, LevelMaximum), and the captured rows agree — every level floor rises with the region.

TWO THINGS IN THE CAPTURE ARE DELIBERATELY NOT IMPORTED:

  • the portal type mixes WHICH KIND the time-space is with WHETHER THAT PLAYER had cleared it. The capture's player had finished everything, so every row reads "Done"; importing it literally would hand every account a completed game. Only the hero/normal bit is kept, and no wp we send ever claims completion, because nothing records completions.
  • the ScriptedInstanceId looks like a key and is not one — id 79 appears on maps 132 and 133, because one time-space has two doors. Rows get their own key and wp carries that.

THE SCRIPT FORMAT IS NOT OURS, ON PURPOSE. Instance content for this game has only ever been written in one shape: a Definition element with Globals and a list of CreateMap elements. Inventing a nicer one would mean nobody could bring the content they already have. Every field is optional, because real scripts omit whatever their instance does not have; malformed XML throws, because that is a mistake and hiding it behind a door that opens onto nothing helps nobody.

Only the declarative half is modelled. The same XML carries an event tree — waves, timers, locked doors, objectives — about forty node types deep, which needs a runtime; a script carrying it loads and the events are ignored rather than the instance failing.

A RUN IS NOT AN ENTRANCE. A ScriptedInstance is the door, one per entrance for the life of the server; a ScriptedInstanceRun is what happens after somebody opens it, one per party, with its own rooms and its own remaining lives. Conflating them is how two parties end up in the same rooms, so there is a test that says two entries never share a room. A run is torn down when the last of its rooms empties — per run, not per map, so a party split across two rooms keeps both.

ALSO FIXED, found on the way: PersistenceModule discovered DAOs by testing the type NAME for "InstanceDto" unless it also said "Inventory". That was meant to skip the item-instance hierarchy, which is registered by hand, but ScriptedInstanceDto matched too — so the table had no Dao at all and was unreachable from code. The test now asks the type system (IItemInstanceDto) instead of the spelling.

EXPECTED: run the parser and the table fills. Walk onto a map with a time-space and the marker is drawn with its level requirement. Click it and the entry panel opens. Press Start and, if the row has a script, you are inside a private copy of its rooms; if it has none you are told so, which is true — instance content has to be authored.

STATED RATHER THAN GUESSED, each written next to the code: TsConditionType has no field in the script format (CanEnterAlone is the least restrictive reading); Completed and HighScore are per character and nothing records them; and the rbr field layout follows NosCore.Packets, which disagrees with the older emulators in two places that the capture cannot settle.

Validates time-space requests, enforces level limits, moves characters into rooms, sends destination waypoints, and integrates scripted-run cleanup with map changes.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 62265

The PR adds persisted entrance import and private instance entry, but the current behavior can misassign entrances, mutate definitions after construction, split party members into different runs, and show or enforce incorrect level requirements. Merge should wait for these correctness issues to be fixed or explicitly accepted.

Use the effective level range in GenerateWp.

GenerateRbr in ScriptedInstance.cs prefers the script values through EffectiveLevelMinimum and EffectiveLevelMaximum. GenerateWp sends the imported LevelMinimum and LevelMaximum. For an entrance whose script overrides the range, the minimap marker and the entry panel show different requirements.

Use TryParse so one corrupt token does not abort the import.

The class remarks state that a capture line can be cut in half. The length guards cover a line that loses whole fields. They do not cover a line that keeps the field count but truncates a number, for example wp 134 3 followed by a corrupt tail. short.Parse and byte.Parse then throw, and the exception propagates out of RunFullImportAsync, which stops the remaining imports.

Backfill the new ScriptedInstance fields for existing rows. The migration initializes IsHeroic to false and both level bounds to 0, while re-import skips existing positions. Existing time-space entries can therefore retain incorrect metadata and reject every character above level 0 unless a script override applies. Backfill the correct values while preserving each existing Script, or define an explicit unrestricted fallback.

Use a party-scoped run contract.

InstantiateAsync requires a new run for every call. TreqPacketHandler calls it for only the requesting session. Members of the same party therefore create separate runs and cannot enter together.

Add a party identity to the service contract. Create or retrieve one active run per party atomically.

Agreed on the direction, and I built the alternative rather than argue it — InstanceDefinitionBuilder, so a definition is code the compiler checks:

InstanceDefinitionBuilder
    .Named(id: 3, label: "Cuby", title: "Mother Cuby")
    .ForLevels(20, 45)
    .WithLives(3)
    .StartingAt(12, 34)
    .Rewarding(gold: 15000, reputation: 200)
    .WithRoom(2004, out var entrance)
    .WithRoom(2005, out var lair, indexX: 1)
    .Requiring(1000, 2)
    .Drawing(1012, 3, design: 7, randomRare: true)
    .WithSpecialReward(2282, 1, heroic: true)
    .Build();

Room keys are handed out instead of typed twice, which is the part the XML could not do: there the same number went in the room and again in everything pointing at it, and nothing checked the two agreed.

Why the XML reader is still in the branch, and this is the decision I want from you. It is the only thing that produces a definition today. ScriptedInstanceService parses ScriptedInstance.Script, the column the table already carries; IScriptedInstanceService.Register — the door a builder-made definition comes through — has no caller outside tests. Delete the reader now and every entrance the parser imported has rooms but no definition, so treq opens nothing until each one has been written out by hand.

So, either:

  1. the reader stays as the transitional path and the builder is how new instances are written, the column being retired once they all are; or
  2. it goes in this PR, and I write out the instances we can source as builder calls — that is a much bigger diff than this one, and this PR has already been called too big.

My preference is 1, with the reader marked as the thing being retired. Tell me if you want 2 and I will do it.

Pushed a follow-up. Comments cut (371 lines), and the three new resource strings are now actually translated in all eight non-English files rather than left in English.

CodeRabbit found three real ones and I fixed them:

  • The service was transient. The convention scan registers discovered services as transient unless they implement ISingletonService, and it runs after the explicit AddSingleton — so every resolution started with an empty run index and no run was ever found or disposed. Marked, and the explicit registration removed.
  • A run could be destroyed mid-transfer. Walking between two rooms of the same instance leaves the character in neither for a moment, and the empty check ran in that window — tearing down the room they were walking into. It now runs after the destination session is registered.
  • treq trusted the coordinates. A modified client could name any entrance on the map. It now requires the character to be standing next to the one it names.

Also: a zero level ceiling is treated as no ceiling, so rows that predate the column do not turn everyone away.


On the XML — you are right, and I would rather not defend it. I used the OpenNos shape only because it is what existing hand-written instance content is written in, but that is an argument for a one-off importer, not for the runtime format.

What would you like instead? My inclination, if you have no strong preference, is definitions as C# in the codebase — a small fluent builder per instance, compiled, greppable, refactorable, and testable, with no parser and no string-typed room references. It costs the ability to hot-edit an instance without a rebuild; if that matters to you, JSON files under configuration/ with a schema would keep it.

Happy to split this PR if you prefer: the entrance import, the minimap markers and the entry panel do not depend on the format at all, and the run/room machinery could follow once the format is settled.

Use the effective level bounds in waypoint packets.

Register can attach a definition that overrides persisted bounds. TreqPacketHandler enforces the effective bounds, but these fields send the raw DTO values. If the values differ, the client shows incorrect entry requirements.

Register the destination session before cleanup.

DisposeIfEmptyAsync checks MapInstance.Sessions. At Line 175, the destination channel is not added until Lines 250-252. If the final player moves between rooms in the same run, every room appears empty and cleanup removes the destination room.

Move this cleanup after the destination Sessions.Add, or register the destination session before cleanup.

Following up on the XML — I built the alternative rather than leaving the question hanging, so there is something to look at. A definition now reads like this:

InstanceDefinitionBuilder
    .Named(id: 3, label: "Cuby", title: "Mother Cuby")
    .ForLevels(20, 45)
    .WithLives(3)
    .StartingAt(12, 34)
    .Rewarding(gold: 15000, reputation: 200)
    .WithRoom(2004, out var entrance)
    .WithRoom(2005, out var lair, indexX: 1)
    .Requiring(1000, 2)
    .Drawing(1012, 3, design: 7, randomRare: true)
    .WithSpecialReward(2282, 1, heroic: true)
    .Build();

Room keys are handed out rather than written down, which is the part the XML could not do: there, the same number had to be typed in the room and again in everything pointing at it, and nothing checked the two agreed. Here a stale reference is a build error.

Being straight about the state: the builder is written and tested, but nothing uses it yet — ScriptedInstanceService still calls ScriptedInstanceDefinitionParser.Parse(row.Script). So right now the PR carries a proposal next to the thing you objected to, and the thing you objected to is still the live path. That is not a state worth merging.

What I would do next, unless you say otherwise. You asked on #2281 for smaller PRs, and this splits cleanly along that line:

  1. Entrance import, minimap markers, entry panel. Does not depend on the definition format at all — wp/rbr from the capture, treq, the level-range checks. This is most of the diff and none of the argument.
  2. Run and room machinery, on whichever format you settle on.

That gets the uncontroversial part reviewable on its own and leaves the format question in a small PR you can take your time over.

Two things I would still like your call on, because guessing them wastes both our time:

  • C# or JSON? C# gets compiler checking and refactoring; JSON under configuration/ keeps the ability to change an instance without a rebuild. I lean C# but I do not have to live with the content pipeline — you do.
  • The existing XML content. There is hand-written instance content in that format. I would keep the parser as a one-off importer that emits definitions, clearly not the runtime path — but if you would rather that content be rewritten, the parser goes entirely.

Every one of #2292's 19 files is also in this PR's 34, so the two overlap completely rather than stacking. Both are green, but merging one will conflict the other.

Which is the base? If #2292 is the import half split out of this one, I'd merge it first and rebase this on top so the migration lands once. If this PR supersedes it, #2292 should close.

Not reviewing the content further until that's settled — no point reading the same migration twice.

#2292 is the base. This PR was written whole and #2292 is the import half split out of it afterwards, so they both branched from master rather than stacking — which is exactly the complete overlap you measured.

I've rebuilt this branch on top of #2292 rather than leaving the question open. Its three commits are now #2292's two plus one, so the moment #2292 merges this collapses to the fifteen runtime files: the service, the run, the definition builder, TreqPacketHandler, the two map hooks and their tests.

One thing worth knowing, because it decides which copy survives: the two had diverged. A plain rebase --onto conflicted in four files — each branch had taken review fixes the other hadn't. Rebuilding on #2292 keeps the version reviewed there, including the backfill fix where a stored entrance was skipped instead of having its metadata refreshed. That fix only exists on #2292, so merging in the other order would have lost it.

Two language keys came across because only the runtime uses them, TIMESPACE_LEVEL_NOT_ALLOWED and TIMESPACE_NOT_AVAILABLE, translated in all nine resource files.

Solution builds with zero warnings; NosCore.GameObject.Tests 409/409, NosCore.Parser.Tests 110/110. No play test — I don't run the servers.

…ing it

This branch now sits ON TOP of pr/instance-entrances (NosCoreIO#2292) instead of carrying
its own copy of the same work. Once NosCoreIO#2292 merges, what is left here is the
fifteen runtime files and nothing else.

WHY IT LOOKED LIKE TWO PRs THAT OVERLAP. They were never stacked: this PR was
written whole, and NosCoreIO#2292 is the import half split out of it afterwards. So both
branched from master and both carried the parser, the entity, the migration and
the resources - which is exactly the "every one of NosCoreIO#2292's 19 files is also in
this PR's 34" you measured.

The two copies had also DIVERGED, which is why a plain rebase conflicted in four
files: each branch had taken review fixes the other had not. Rebuilding on top of
NosCoreIO#2292 rather than merging the two histories keeps the version that was actually
reviewed there - including the backfill fix, where a stored entrance was skipped
instead of having its metadata refreshed.

Two language keys had to come across because only the runtime uses them:
TIMESPACE_LEVEL_NOT_ALLOWED and TIMESPACE_NOT_AVAILABLE, translated in all nine
resource files.

WHAT WAS TESTED: whole solution builds with zero warnings.
NosCore.GameObject.Tests 409/409, NosCore.Parser.Tests 110/110. No play test -
the NosCore servers are not being started.

The overlap you measured is gone — this is now rebased on master with #2292 merged, so the import half is no longer duplicated here.

34 files → 25, 5897 → 1330 lines, and the two commits that carried #2292's content were dropped as already applied rather than replayed. I checked master keeps the part that mattered before dropping them: the parser updates a stored entrance instead of skipping it (stored.TryGetValue reusing the id and script), so nothing was lost in the collapse.

Also removed on the way through:

  • the merge commit — git log --oneline --merges origin/master..HEAD prints nothing;
  • 11 ConfigureAwait(false) the branch was adding. MapChangeService had none of its own on master, so all eleven were mine.

What's left is the runtime half only: the service, the run, the definition builder, TreqPacketHandler, the two map hooks and their tests.

How it was verified: dotnet build NosCore.sln 0 warnings, dotnet test NosCore.sln 1018 green across the five projects it runs. Not played — no client was attached to this branch, so the behaviour claims here rest on the unit tests and the data files, not on a session.

One thing worth flagging that is not from this branch: NosCore.Parser.Tests is red on current master — BCardVocabularyTests.EveryDeclaredEffectIsNamed fails with type 91 subtype 32 and subtype 42 having no BCardEffect member, 139/140. I measured it on a clean checkout of origin/master as well as here, and this branch touches no BCard file. It stays hidden because that project doesn't run in the usual solution-wide pass.

Correction to my previous comment: master is not red, and I was wrong to say so.

BCardVocabularyTests.EveryDeclaredEffectIsNamed carries [TestCategory("OPTIONAL-TEST")], and every dotnet test line in the workflow passes --filter TestCategory!=OPTIONAL-TEST. So it is opt-in by design, exactly as its own comment says — the vocabulary is unfinished and the test is there to measure that, not to gate. I ran the suite without the filter, read a failure, and reported it as a regression without checking whether it was meant to run.

What is true, and much smaller: BCard.dat declares type 91 subtypes 32 and 42 — the second halves of Moonlight Absorption and Gathering Petals — and BCardEffect has no member for either. That is two more rows of the same unfinished vocabulary the test already tracks, not something that broke.

Nothing about this PR changes: it touches no BCard file, and the filtered suite is green.

…s reused

Build() handed out the builder's own lists, so a later WithRoom or WithReward
also changed every definition already built.
