LogicMath::sqrt is a 256-entry table of floor(16*sqrt(i)) with a seed
picked by magnitude and one or two newton steps on top, and it is not
exact: above 2147441940 the seed overshoots and the single correction
cannot pull it back, so it answers 46341 where the true root is 46340,
and 65535 for INT_MAX.
that matters because the checksum is computed over whatever it returns.
an honest square root would be a permanent, invisible disagreement, so
this one is transcribed branch for branch - including the early -1 for
negatives and the INT_MAX special case - and our own converging root is
gone. checked against the exact root across the low range and the
boundaries, where the two agree, and at the top, where they must not.
distances now go through the saturating helper before the root, the way
the client does it, rather than being squared in i64 on the way in.
a LogicDoSpellCommand names a deck slot, so the card comes from the deck
we sent for that player, and the owner comes from matching the command's
executor account against the two the battle carries. the spell row's
SummonCharacter and SummonNumber say what and how many to place, at the
position the command carries.
the object factory behind the towers is now shared: hitpoints and the
combat/hitpoint/buff components are built the same way for a summoned
character as for a tower.
these objects are not encodable yet. a character with Speed gets a
LogicMovementComponent on the client, and we have no encoder for that
component, so the server copy must not be turned back into a snapshot
until it exists. nothing re-encodes it today - it feeds the clock, the
crowns and the end condition only.
field order taken straight off LogicBattle::encode. the object manager is
columnar, not object major: 6 counters, a count, then all data refs, then all
global ids, then all objects, then four component passes. global ids must be
ascending, the client binary searches them.
LogicRandom moved out of the shop into its own module. its abs was
checked_abs().unwrap_or(0), the binary uses NEGS so i32::MIN stays i32::MIN.
one seed in four billion, but it would have desynced the card shop.
per object subclass encodes and the component payloads are still missing, so no
snapshot can be sent yet.
14303 AskForJoinableAlliancesList and 14107 CancelMatchmake are both genuinely
empty payloads. 516 UpdateLastShownLevelUp is header only, 537 StartMatchmake
carries a vint and a bool. none of them move the home checksum.
that clears the unknown type warnings out of the log.
500 LogicSwapSpellsCommand does the real work, 520 and 521 are no-ops in this
build so they just decode. 535 puts its data reference BEFORE the base header,
unlike every other command.
collection only shrinks when a card moves into an empty deck slot, that is the
one case where the home checksum moves.
json stores are gone, they nulled out every data ref on load and wrote the null straight back on save.
shop json and the purchase commands ended up in here too.
