Keep character selection atomic when mate loading fails.
If mateService.LoadAsync throws at Line 255, the outer catch runs after clientSession.SetPlayerEntity has already attached the new entity at Line 204. The session can then retain a partially initialized character without receiving the successful-selection response. Load mates before committing the entity, or roll back the entity and subscription in the catch block.

this has nothing to do here we have a library for stats/xp calculation
|
Comments cut — 179 lines gone. "we have a library for stats/xp calculation": agreed. Opened NosCoreIO/NosCore.Algorithm#129 with "that should be sorted by the packet serialization itself not manually": you are right, the space-to-caret substitution has no business being at every call site. It belongs in the serializer, alongside a second problem I hit: a null sub-packet loses its separating space, so "did you check that on official?" (the 2 000 000 id seed) — no, and thank you for asking, because the honest answer is that I took it from the older emulator's convention rather than from evidence. The capture shows official mate transport ids in the same five-digit range as everything else (26716-26724), so the real server does not keep a separate band at all. Ours only has to avoid colliding with monster and npc visual ids, which start well below that — but if you would rather mates draw from the same space as other entities, say so and I will change it. |
|
Follow-up on the escaping: you were right, and it needed no library change at all — The null sub-packet problem was real though, and is up as NosCoreIO/NosCore.Packets#493. |
|
Extended this one rather than opening a second PR, since it is the same feature: the mate now actually appears on the map. Before this it loaded and showed in the pet window and that was all — nothing put it anywhere you could see it. It now spawns beside its owner on arrival, is announced to everyone else on the map, gets its health bar, and is taken away when the owner leaves. The shapes come off the capture, not from the older emulator:
A freshly caught pet joins the team if the pet slot is free, because that is what catching one does in game — it walks out beside you rather than going into storage. Not in this PR: the mate stands where it is put. Following the owner step by step wants the movement system and is its own change. |

Make active-pet assignment atomic.
Two concurrent captures can both observe no active pet before either insert completes. Both rows then persist with IsTeamMember = true, which violates the one-active-pet rule.
Enforce this invariant in one transaction or with a database constraint and conflict handling. Do not rely on this separate Where(...).Any() check.

Three more from review, all real, all fixed — plus the mate now follows its owner.
A newcomer could not see anybody else's mates. The map-entry loop announced the characters already present but not what was at their heel, so every pet on a populated map was invisible to whoever walked in. Caught by CodeRabbit and entirely right. Two rows could claim the same mate slot — two captures racing, or a hand-edited database — and the second would spawn on top of the first with nothing raised. Rather than a transaction, the reader now decides: the first row keeps the slot and the rest stay in the list. Cheaper, and it repairs a database that is already inconsistent. And the mate keeps up. It moves on the same |

A design question before I go further, because the answer decides the shape of the next PR. Mate combat ( Which way would you like it?
I lean towards 1 — a mate is closer to a monster than to an inventory item, and it is what unblocks the roughly forty-five BCard subtypes that only mean something with a mate in the fight.

Right again, and it is the mirror of the one from before: I gated the arriving character's own mates on their invisibility but not the loop that tells them about the players already there. A pet's spawn names its owner, so a hidden character was being announced by somebody else's screen. Fixed. |
WHAT: a Mate game object, a MateService that loads a character's mates, a
PlayerMatesComponent on the player bundle, loading at character select, and the pet-list
burst at game start.
WHY: CaptureService writes a MateDto row every time a pet is caught, and nothing ever read
it. The row went into the database and the pet was never heard from again — the catch
worked and produced nothing a player could see.
SOURCE: a real packet capture. It settles three things that would otherwise have been
guesses:
* the login order — p_clear, one sc_p per pet and sc_n per partner, then sc_p_stc;
* that pets and partners are numbered from zero SEPARATELY (sc_p slots 0..7 sit next to
sc_n slots 0..1 in the same burst);
* the experience table. The curve the older emulators ship is twenty times the pet
requirement and five times the partner one — ten observations from level 1 to level 88
match after dividing, two of them eight-digit numbers, so it is not curve-fitting.
MateXpTable carries the divisors and all ten observations are tests. Worth a look on
its own: nothing throws when this is wrong, the pet just never levels, and it reads as
grind rather than as a bug.
EXPECTED: a caught pet survives the session it was caught in. Log in and the pet window
lists what you own, with its level, loyalty and experience bar.
OUT OF SCOPE, each for a reason written next to it in the code:
* the per-level HP/MP and damage curves. The inherited ones reproduce no captured row —
a level-3 chicken would get 262 HP where the server sent 195 — so the mate reports the
creature's declared statistics: exact at level 1, low above it. Sixteen samples across
three stat families are not enough to derive the right curve; fitting one would be
inventing it.
* pinit for mates. The capture gives a mate row eight fields; PinitSubPacket serialises
eleven, because its last three members are non-nullable value types. Sending a shape an
authoritative source contradicts is worse than not sending it — happy to send a
NosCore.Packets change for this if you want it.
* empty partner equipment slots. The capture writes them as a bare -1; leaving the
sub-packet null makes the serialiser drop the separating space and emit "1536-1-1-1".
All three numbers are filled instead (-1.0.0), which keeps the field count right.
Unreachable today, since nothing creates a partner yet.
* summoning onto the map, combat, loyalty, feeding, the partner's specialist card. Each
is its own slice.

StringSerializer already replaces the separator with a caret for every non-final string field, so doing it by hand was doing it twice. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The previous commits made a caught pet survive and appear in the pet window. It still could
not be seen: nothing put it on a map.
A mate now spawns beside its owner on arrival, is announced to everybody else on the map, and
is taken away again when the owner leaves. Its health bar goes to the owner.
The spawn shape is read off a capture rather than guessed:
in 2 1506 445562 26 26 2 100 100 0 0 3 626114 1 0 -1 Ratufu^pirate^(Feu) 0 -1 ...
Owner and GroupEffect=3 are what separate a mate from a map npc — without them the client
draws it as scenery and will not let the owner command it. The byte after the name is 1 for
every partner in the capture and 0 for every pet.
pst 2 22687 0 100 100 24471 3100 0 0 0
The third field carries the mate type where a player's carries a party position.
A newly caught pet joins the team when the pet slot is free, which is what catching one does
in game: it walks out beside you rather than going into storage. A second pet waits, because
a character keeps one pet and one partner out at a time.
The mate is placed next to the character rather than on its stored square: that square
belongs to whichever map it was last saved on, and reusing it here would put a pet through a
wall.
Not yet: the mate stands where it was put. Following the owner step by step needs the
movement system and is its own change.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A mate that stays where it was summoned looks broken long before it looks unfinished, so it moves on the same event a character's own step already publishes rather than on a timer of its own. It takes the first walkable square around the owner, so a mate against a wall tucks in somewhere instead of refusing to move, and two mates never stack. With nothing free at all it stands on the owner — untidy, and better than being left behind on the far side of the map. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
p_clear wipes one panel that holds both the party and the mate list, and the party burst was straddling it — so pinit and pst were being cleared on every game start. Both bursts now follow it, in the order the capture shows: p_clear, sc packets, sc_p_stc, pinit. A player walking onto a populated map was told about the characters already there but not about their mates, so every pet on the map was invisible to them. Two rows can claim the same mate slot — two captures racing, or a database edited by hand — and the second would spawn on top of the first with nothing raised anywhere. The reader now decides: the first row keeps the slot and the rest stay in the list. That is cheaper than a transaction and it also repairs a database that is already inconsistent.

A hidden owner's mates were still broadcast to the map. A visible pet carrying an Owner field announces the character it belongs to, so invisibility leaked through the pet. Their spawns and their moves now go to the owner alone while they are hidden. Both mates were being placed on the same fixed offset from the owner, which also happened to be a square that might be a wall or off the map. The placement the follow already used is now shared: each mate takes its own walkable square, and the owner's own square is the fallback when nothing is free.

Answering my own question from the review rather than leaving the PR waiting: a mate becomes an ECS entity, with the component set a monster has. That is what lets it go through IBattleService.Hit like anything else that fights. The skill resolver already branches on INonPlayableEntity and reads the creature off NpcMonster, so a mate resolves its basic attack exactly as a monster does — no second damage path to keep in step, and no second notion of "combatant" in the codebase. It also unblocks the BCard subtypes that only mean something with a mate in the fight. The entity's life is the map's: created on arrival, destroyed on leaving, position written on every step. Leaving it behind would strand a mate in a world nobody is in, and moving only the packet would leave it visibly in one place and actually in another — which is what a monster picking a target would read. u_pet checks that the mate belongs to the character asking and is actually out, because trusting the id in the packet would let a client drive somebody else's pet. If you would rather mates stayed out of the ECS, say so and it comes back out: the fold of effects is the part that matters and it does not depend on the container.

The mirror of the leak already fixed: the arriving character's own mates were gated on their invisibility, but the loop telling them about the players already on the map was not gated on those players'. A pet's spawn packet names its owner, so an invisible character was announced by somebody else's screen. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The local MateXpTable and its tests are gone: NosCore.Algorithm 2.1.0 ships IMateExperienceService, which is where you said it belonged. The value is written when the mate is loaded rather than computed on the object — a data object has no business resolving a service, and the number only changes on level-up. The ten capture observations that pinned the divisors live with the curve now, as approval tables in that repository. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Rebased on master. Thanks for #2287; closing mine was the right call, and bundling the Algorithm bump with it saved a round trip. |

we only need a single way to do all in so that's wrong

Likely this can be split more into smaller PR and also need a good thought on the process as the goal is not just to copy what OpenNos did because that's not the best code possible for lot of those concepts
Review feedback on NosCoreIO#2281: packet generation has no business living on the game object. GenerateScp/Scn/In/Out/Pst/Cond become extension methods on Mate in NosCore.GameObject.Ecs.Extensions, matching how every other entity does it. Also: drop the SpawnComponent comment in MapWorld.CreateMate, and replace the nested null check in MapChangeService with a where clause.

Done, thanks:

The remarks blocks and the multi-line explanations are gone; what is left is a line where a reader would otherwise get it wrong, and the capture lines that pin a field. 148 comment lines down to 121 across a 1100-line diff. Eleven files had also picked up a UTF-8 BOM, each showing as a whole-line diff against master. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Stripping them blindly was wrong for these two: master carries a BOM on both, so removing it turned a small change into a whole-file diff. Match master, do not strip. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Cut the comments right down across all seven open PRs — the remarks blocks are gone and the long explanations are a line each. What I kept is the captured packet lines that pin a field, and the odd note where a reader would otherwise get it wrong; everything that was retelling what the code already says is out. Also cleaned up a UTF-8 BOM problem I'd introduced: a number of files had picked one up and were showing as whole-line diffs against master. Fixed by matching master per file rather than stripping — the .resx files do carry one upstream, so blanket-stripping was its own kind of noise. Builds clean, all tests green on each branch. |

WHAT: a Mate game object, a MateService that loads a character's mates, a PlayerMatesComponent on the player bundle, loading at character select, and the pet-list burst at game start.
WHY: CaptureService writes a MateDto row every time a pet is caught, and nothing ever read it. The row went into the database and the pet was never heard from again — the catch worked and produced nothing a player could see.
SOURCE: a real packet capture. It settles three things that would otherwise have been guesses:
EXPECTED: a caught pet survives the session it was caught in. Log in and the pet window lists what you own, with its level, loyalty and experience bar.
OUT OF SCOPE, each for a reason written next to it in the code:
