New plant content, all driven by genes through the trait layer (no engine
change — the genetics machinery already supports it).
- ProductDef + products.json (wood, grass, berries, acorn) — what plants
yield; localized labels (ru/en).
- New numeric genes (genes.json): GeneFruitYield, GeneFruitSeason,
GeneHarvestAmount, GeneLeafHue, each declaring its trait via formula.
GenomeDef carries the per-species bases (PlantSet maps them into the
species template); PlantDef gains harvestProduct / fruitProduct.
- PlantPhenotype gains FruitYield/FruitSeason/HarvestAmount/LeafHue.
PlantFactory tints the sprite from the leaf-hue gene (combined with the
morph variant). Plants carry a Fruiting component; PlantFruitingSystem
ripens fruit on mature plants during their gene-chosen season and drops
it off-season.
- plants.json: trees give wood + acorns (autumn), bushes berries (summer),
grass gives grass — amounts/season/hue from genes.
- 'plant <species> [seed]' console command samples a species genome and
prints its gene-driven traits and products.
Build clean; def JSON validated; boot smoke loads the new content.

LittleSim.Web (Blazor WASM + KNI/WebGL) is a real network client now: it
connects to the dedicated server over WebSocket (ClientWebSocket maps to
the browser socket), applies MrGameEng.Net delta snapshots into its
EntityStore and draws pawns through SpriteBatch — fatigue dims them just
like on desktop. The server address comes from ?server=ws://host:port
in the page URL, defaulting to the page's host on port 9050. The net
contract is mirrored in NetContract.cs (KNI and DesktopGL assemblies
can't mix until the graphics libraries build per platform) with loud
keep-in-sync comments on both sides.
Both clients now smooth replicated positions between 10 Hz snapshots:
NetLerp + NetSmoothingSystem lerp the visual position toward the latest
server position every frame (exponential, ~0.25 s to converge).
Verified against a live LittleSim.Server --listen: the browser client
connects (server log), draws ~3.3k lit pixels of pawns whose layout
changes between samples, and survives 400+ ticks without errors. Found
along the way: requestAnimationFrame freezes in hidden windows — the
game loop only runs while the tab is visible.

Plants now carry a managed Genome and read formula-computed traits
instead of the hardcoded PlantGenome struct. Engine pointer -> ead2251
(GenomeTemplate + Breed mutationChance override).
- PlantOrganism { Genome; PlantPhenotype Traits } replaces PlantGenome.
Traits (optima/tolerances, vigor, lifespan, dispersal, reproduce
interval, self-pollination, mutation rate, morph variant) come from
Phenotype.Compute over the gene effect formulas in genes.json.
- PlantSet builds a per-species GenomeTemplate by mapping each species'
existing plants.json genome numbers onto the shared GeneDefs, and
exposes the gene registry. Species values unchanged — only reinterpreted
through genes now.
- Growth and lifecycle systems read PlantOrganism.Traits; breeding goes
through Genome.Breed with the registry and a mutation chance averaged
from the parents' evolvable mutationRate trait. Scatter generates from
the species template.
- Save stores the genome as a geneId->Allele map; load rebuilds it
(empty/legacy saves regenerate from the template — dev saves disposable).
Behaviour matches phases A-D, now fully data-driven through genes and
formulas. Full suite green; boot smoke test loads genes + plants cleanly.

Engine bump brings MrGameEng.Net (WebSocket transport, RFC 6455 server,
delta component replication) — this commit is its showcase.
LittleSim.Server --listen runs the world online: 24 pawns wander, tire
and rest on the engine's fixed-tick HeadlessHost (the same Wander/
Needs/Decision systems the windowed world uses), a WebSocketServer
accepts clients and a ReplicationServer ships Transform2D + PawnNeeds
deltas at 10 snapshots/s per the shared NetSchema. --probe is the CLI
check: it connects, listens for a second and prints replicated pawns
with positions sampled twice to show the world is alive.
The game gains MultiplayerScene (dotnet run --project src/LittleSim --
--connect [ws://host:port]): simulation stays on the server, the client
applies snapshots into its scene store, decorates spawned entities with
sprites and reuses PawnAppearanceSystem so replicated fatigue darkens
pawns locally. HUD strings go through ru/en localization; the `net`
console command reports connection state and entity count. Esc returns
to the main menu.
Verified end to end: probe sees 24 pawns moving between samples; the
windowed client connects and runs against a live local server.

Engine pointer -> bc18db5: brings in the organism-agnostic gene
foundation (GeneDef, managed Genome, Phenotype trait computation) plus a
parallel MrGameEng.Net library the game does not use.
Game wiring: register the "Gene" def type and ship Mods/Core/Defs/
genes.json — a full gene set covering the plant phenotype dimensions
(environment optima/tolerances, vigor, lifecycle, reproduction) plus a
discrete morph gene, each declaring its trait effects as formulas. A
dev-console 'gene [seed]' command generates a genome from these defs,
prints its alleles, expressed values and computed traits, then breeds a
child — demonstrating the whole pipeline end to end. These genes seed
the G3 migration of plants onto traits.

Engine pointer -> 10898b0, which brings in two engine changes:
- the gene-system formula engine (Core): a data-driven expression
evaluator that compiles a def string once and evaluates it
allocation-free against a variable context;
- a parallel refactor splitting the platform out of Core into a new
MrGameEng.Host library.
Game migration for the Host split: reference MrGameEng.Host (+ add it
and its test project to the solution), import MrGameEng.Host where
GameHost/GameHostOptions/Input are used, switch Transition.Fade ->
Transitions.Fade, and read the device via context.GetGraphicsDevice()
now that EngineContext is platform-free.
Showcase the formula engine with a dev-console 'formula <expr>' command
that compiles and evaluates an expression. Also adds docs/гены.md, the
gene-system design doc (phases G1-G5).

spikes/KniWeb (outside LittleSim.sln): a kni-blazor-gl template project
(KNI 4.2.9001, net8.0) referencing MrGameEng.Core directly. A mini-host
in the GameHost mold drives EngineContext/GameClock/Scene phases over
KNI's Game; the scene moves 300 Friflo entities in the update phase and
draws them with SpriteBatch (WebGL). Verified in a real browser: sprites
render and animate, browser console is clean.
Decision (docs/web-client.md): path A — KNI — is the primary route for
the web client; the core runs in Blazor WASM unchanged thanks to the
Core/Host split. Known follow-ups: per-platform compilation of the
graphics libraries against nkast.* packages, shader compatibility for
Renderer2D, HTTP-served content instead of the filesystem.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Engine bump: MrGameEng.Core is now platform-free (Friflo only), the
windowed MonoGame host lives in the new MrGameEng.Host library, and the
core gains HeadlessHost — a fixed-timestep loop without a window or GPU.
Game side: scenes switch to Transitions.Fade from the Host library,
WorldScene reads the graphics device via Context.GetGraphicsDevice(),
GameContent.Load(buildAtlases: false) skips atlas building for headless
runs.
LittleSim.Server is the dedicated-server seed and the showcase for
HeadlessHost: it loads mods/defs without textures and fast-forwards the
world calendar and climate on a fixed tick (~3.6M ticks/s in Debug):
dotnet run --project src/LittleSim.Server -- --days 10 --tps 60

Bump the engine submodule to 79d406a (2D lightmap). The world scene now uses
UseLighting instead of the per-sprite ambient: a lightmap multiplies day/night
× occlusion over the world, so forests cast soft shade and the world darkens
spatially toward night. Occluders are mountains (new TerrainDef.BlocksLight)
plus mature trees, rebuilt from the live population. PlantGrowthSystem samples
the local light per plant (Lighting.SampleAt), so undergrowth under canopy
grows slower. A dev-console 'light' command places a point light at the cursor
to show cast shadows at night. Completes the plant ecosystem (A–D).

Plants now live full lives. The genome gains lifespan, dispersal, fecundity,
self-pollination, mutation-rate and a discrete dominant/recessive Morph gene;
PlantGenome.Breed models meiosis (one allele per parent) plus mutation. A
gated PlantLifecycleSystem builds a per-cell grid (density + a species/genome
representative), reaps plants past their lifespan, and lets mature plants seed
offspring — cross-pollinating with a mature same-species neighbour in dispersal
range (falling back to self-pollination by gene) into a nearby land cell under
the density cap. A shared PlantFactory creates every plant (initial scatter,
births, save restore) and tints recessive-morph plants. Growth keeps aging
mature plants so they can die of old age. The whole population (genomes,
positions, age, stage) is saved to WorldSave and restored on load instead of
re-scattering from the seed. plants.json carries the new genes.

Bump the engine submodule to d0104df (Suitability.Gaussian). Each plant now
carries a diploid PlantGenome (allele pairs, phenotype = allele average) seeded
from a per-species GenomeDef baseline at spawn. PlantGrowthSystem replaces the
flat fertility multiplier with vigor times a product of Gaussian suitabilities
for light (day/night), temperature (climate season) and the cell's fertility —
so plants grow faster in their preferred light/warmth/soil and crawl outside it.
Genomes are visible and editable in the ECS inspector. plants.json carries the
species genomes.

Bump the engine submodule to a684c23 (Climate + day/night ambient). The
world scene now registers UseClimate and UseDayNight, so it darkens at
night and the HUD shows the season and temperature alongside the date.
Add docs/растения.md capturing the whole plant-ecosystem design (growth as
a suitability product, hybrid Mendelian genome, climate, lighting with
shadows, reproduction, persistence) and the A-D phase plan.

Bump the engine submodule to f39ee9e (half-texel UV inset that removes the
black tile seams seen while zooming). Add a Fertility multiplier to
TerrainDef (forest soil rich, sand/mountain poor); plants record their
cell's fertility as PlantGrowth.GrowthRate at spawn, and the growth system
multiplies the per-frame calendar day-delta by it — so growth stays tied to
the in-game calendar and runs faster on fertile soil.

The mouse-wheel zoom now keeps the world point under the cursor fixed
(cursor-anchored zoom) by shifting the camera position after applying the
new zoom, instead of zooming around the camera centre. GodCameraSystem
takes the renderer to map the cursor to world space.

Bump the engine submodule to 4b91b60 (calendar time of day) and display
the current date and time in the world HUD (День N, HH:MM) instead of just
the day number. Set the day length to 480 scaled seconds so the base (x1)
speed runs at 3 in-game minutes per real second.

Update the PlantGrowth component and PlantGrowthSystem to improve plant growth stages based on the calendar. Introduce a new PlantDef structure with a Stages list for texture, size, and growth duration, allowing for more dynamic plant behavior. Adjust WorldScene to utilize the updated growth logic, ensuring varied initial maturity and seamless integration with the calendar system.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Bump the engine submodule to 09dbdfa (MrGameEng.Inspector) and wire the
new DevTools-style ECS debugger into WorldScene via UseInspector(renderer),
before UseDevConsole so the console still draws on top. The HUD controls
hint now mentions F1.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Bump the engine submodule to f791ee6 (Calendar) and use it to drive plant
growth. PlantDef gains a Stages list (texture/size/growDays per stage,
inheritable via abstract parents in plants.json); a resolved PlantSet
table turns those into atlas regions and day thresholds at scene load.
New PlantGrowth component plus PlantGrowthSystem advance each plant by
in-game days from the Calendar and swap its sprite/scale at stage borders.
WorldScene scatters plants again with a seed-deterministic, varied initial
maturity, registers the calendar and growth system, and the HUD now shows
the current day. Stage durations and visuals are pure data in plants.json.

Bump the engine submodule to 5365945 (MrGameEng.WorldGen) and drive
terrain from it: WorldGenerator is now a thin adapter over the engine's
seed-based Perlin/fBm/island HeightmapGenerator instead of the old
random+smoothing pass.
Strip WorldScene down to terrain + camera: render the world as a single
Tilemap entity using per-biome surface textures from the atlas (water
falls back to a tinted tile), and remove pawns, plants, AI systems,
population and save-restore for now. Delete the TerrainScene demo (its
tile approach now lives in WorldScene) along with its console command
and the hud.terrain/population localization strings.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- Added new UI strings for menus, settings, and pause functionality in both English and Russian localization files.
- Introduced a new WorldPresetDef class to define world size and population settings, allowing for dynamic world creation.
- Updated world generation logic to support customizable terrain smoothing and population settings based on user-defined presets.
- Refactored WorldScene to utilize the new WorldConfig structure for improved world initialization and loading.
This commit improves the user experience by providing more options for world creation and enhancing the overall localization of the game.
Wire the engine's new MrGameEng.AI module into a PawnBrain for world pawns,
plus surrounding content/scene tweaks. Apply CSharpier across the game and
document the convention in CLAUDE.md. Add .vscode/settings.json so the editor
formats on save with the CSharpier extension.
The whole game is now described by Mods/Core — the first consumer of
the engine's new MrGameEng.Mods module:
- textures/ moved to Mods/Core/Textures; atlases are built at game
start from the merged texture tree of all active mods into Cache/
(gitignored, incremental) instead of being committed, and the
GameAssets atlas handles are gone with them
- terrain, plants and pawns are JSON defs (Mods/Core/Defs) with parent
inheritance; scenes read TerrainDef/PlantDef/PawnDef instead of
hardcoded arrays, and the TerrainKind enum is retired
- HUD strings come from Mods/Core/Languages (ru default, en fallback)
through LanguageManager; the language switches at runtime
- new console commands: mods, lang [code], defs [type]; atlas now
inspects the runtime-built cache
- bump engine: MrGameEng.Mods module and the explicit-sources
AtlasBuilder overload

CLAUDE.md now states the dual role: every new engine feature gets
demonstrated in this game as part of landing the feature.

Creatures are now animals only (bear, deer, fox, hare, boar, timber
wolf, muffalo, squirrel) from things/pawn/animal, replacing humanlike
pawns and man-made props. Land tiles use proper terrain/surfaces
textures (sand, mossy for grass, soil under forest, rough-hewn rock
for mountains); grass cells get grassa tufts and occasional bushes.
Collisions via the new engine module: animals carry circle colliders
(layer masks: animal vs animal+obstacle), trees get static trunk
colliders, and SeparationSystem resolves overlaps by pushing animals
apart and out of trees after CollisionSystem each tick.

MrGameEng.Pathfinding (A*/Dijkstra/BFS + flow fields for crowds) and
MrGameEng.Collisions (spatial hash, pairs/queries/raycast) are now in
LittleSim.sln. Flow fields are the planned steering tool for villagers.

New texture groups (ui, world, weather, damage, designations) packed into
31 atlases; directories are lowercase now, so scene code switches to the
new region keys (filenames keep their case).

Small seed-generated terrain rendered as a single Tilemap entity: water,
sand and mountains are tinted tiles, grass and forest use atlas textures.
Three wandering pawns and a few props (snowman, lamp, stool, trees) live
on the shared Y-sort layer (now in GameLayers, used by both scenes).
Console: 'terrain [seed]' from the world scene, 'regen'/'world' inside.

Engine bump brings MrGameEng.Atlases (atlas builder + runtime loader).
Textures/ (2747 images) is packed by MrGameEng.AtlasTool into 10 atlases
(93 pages) under Assets/Atlases, loaded through generated handles.
Beings now draw pawn bodies, forest cells grow trees (both Y-sorted),
and the dev console gains 'atlas [name] [filter]' for inspection.

God-game: minimal graphics, deep simulation. The engine lives in the
engine/ git submodule and its sources plus test suites are part of
LittleSim.sln, so engine and game are developed in one editor window.
Playable skeleton: seed-deterministic terrain (smoothed height field ->
water/sand/grass/forest/mountain tinted cells), 80 wandering villagers
on a Y-sorted layer, god camera (WASD pan, wheel zoom, world-bounds
clamp), HUD and the dev console with a 'regen [seed]' command.
CLAUDE.md sets the game rules: simulation-first, one-seed determinism,
simulation/presentation split, a console command for every mechanic.
Design docs in Russian under docs/.
