The server sent the whole army on every snapshot and the client re-cloned
the whole icon layer whenever a unit moved, so a settled world with a
standing army drained the broadcast loop and the frame loop alike.
- Ship only the units and city list that changed, keyed by a per-peer
fingerprint and a serialised hash, and merge those deltas on the client.
- Memoise the battlefield scan on a battle version bumped when a unit
joins, leaves or changes side.
- Skip the DOM writes for units whose snapshot object is unchanged, and
cache the unit-view inner nodes.
- Fold units, cities and tile markers onto the nearest world copy instead
of mirroring the icon layers, which re-cloned thousands of views every
frame; the small decoration layers still mirror, and only on a change.
Frame work at full zoom-out with units moving fell from ~190ms to ~6.5ms.
Rebalanced the resource rules so nothing is priced primarily in money: steel, electricity and high-tech lead every construction bill, chip foundries are seeded everywhere instead of being hand-placed, and cities open with stores of steel and high-tech. City building rows now lead with the resource bill and keep the money as an aside, and the region's resources expand into the buildings that demand them. Pulled the graph and cost maths into a framework-free shared/economy_graph.js, quoted currency through one helper, and gave every data table the same striping and row highlight.
The delivery graph now ships every route the viewer's own storage nodes could trade over, not just the legs that ran, and keeps exports as well as imports so goods leaving the nation appear. The map draws the idle routes grey beneath the active white legs, with a key entry for them.
The population map replaces its bare flow arrows with the arrows plus a disc textured with the origin nation's flag drifting from city to city, mirroring the merchandise that rides the trade graph.
World generation now aims at a fixed share of the ice-free tiles (60%) instead of a minimum continent count, bisecting the water level for it rather than sweeping every step, and still joins the ocean into one body. Ice and tundra are the outermost rows only, scaled down on small maps so the fixtures keep usable land.
Cities score their site, coastal plains best and landlocked worst, avoiding tundra and desert. Every nation that holds a coast gets a port city on each island it owns, and any landmass left empty is settled by the nearest nation, so no land starts unowned. A coastal city opens with a port already built.
Bundles the in-progress work in the tree: the commodity monthly price series and inflation the central bank's chart reads, and the rolling city-to-city migration graph the population map draws as flow arrows.
Central banks now redeem the national money foreign banks hold, sell reserves to defend a weak rate, and cover part of strategic imports from reserves. Five repeatable technologies raise each commodity's output per unit of energy. Hostile troops on a road or sea lane sever trade, power and unit supply. Middlemen buy food to resell to neighbours at a markup, and starving regions buy before those topping up their buffers, which clears the landlocked famines. The economic map's trade graph gains a colour legend.
- Five resources (energy, steel, food, luxury, high-tech) with per-city stores, a world market, delivery and material upkeep.
- Resource-producing tile works built outside cities; every nation opens with the works its economy needs.
- Real game-icons.net art replacing the dummy icons for the new resources and works, with the credits updated.
Marching into enemy territory changes visibility every step, and each change
rebuilt the whole on-screen fog band. A tile's fog depends only on its own
level and its six neighbours', so the exact dependency radius is one tile, far
tighter than the vision radius.
- Every tile owns a fixed slot in one fog buffer, so rebuilding a tile never
shifts another's vertices and only the touched row spans are re-uploaded.
_applyKnowledge now diffs the visible/explored sets and hands the renderer
the changed tiles; buildFogTiles rebuilds them with their rings. On a 100x100
map a frontier patch is ~3-4 ms against ~80 ms for the band.
- A pan that leaves the built rows now builds only the newly exposed rows, and
the escape margin scales with the viewport, so dragging rebuilds rarely.
- _frame schedules the next animation frame before doing any work and catches
an error, so a one-off failure can no longer stop the frame loop for good.
- Added tests for the per-tile patch and the incremental pan.
Marching into unexplored or enemy land reveals a tile every step, and each
reveal rebuilt the whole-map fog mesh: about 1.8M vertices and 50 MB on a
160x160 map, regenerated at the rebuild throttle. Walking through
already-explored home land reveals nothing, which is why the stutter only
showed up on a border crossing, with a single unit.
- buildKnowledge now takes a row range and builds only the rows on screen; the
row table stays full length so the existing row-banded draw keeps working.
- _flushFog rebuilds on a visibility change or a pan to a new row band, still
coalesced, and the draw clamps to the band that was built.
- A mode/zoom change schedules the band rebuild instead of building the whole
mesh, and uniform interior tiles skip the per-vertex blur kernel.
- Tile improvements (fortifications, radar towers, coastal cannons), trenches,
zone of control, support-unit capture and launch transports, with parabolic
barrage arcs drawn between attacker and target.
- Focused research that pours points straight into the chosen technology, with
per-technology progress kept when the focus changes, plus repeatable levels.
- Popularity reworked to integer points, war and pillage effects, minority
policies and month-over-month arrows on the nation summary.
- City progress bars, square improvement buttons, a technology tab of wide
short cards with progress bars, transport cargo readout and double-click to
open a city panel.
