1// nx_wasm_craft.nx -- NISHI CRAFT: a GENERATED 3D VOXEL WORLD, playable first-person. The operator's 2// 2026-05-19 vision ("build minecraft equivalent on the lowest possible hardware") finally EMITTING: 3// procedural terrain (integer value-noise heightmap, biome banding, water, trees) in a 64x32x64 block 4// grid, rendered by a per-pixel integer DDA raycast (true 3D: block faces, face shading, distance fog, 5// sky), walked in first person (collision, auto-step-up, water float), and EDITED live (break/place at 6// the crosshair). Every pixel and every world byte is NishiLang; base-relative so the identical code 7// runs natively (gate, PNG proof) and as wasm (browser page); input arrives through nx_input_abstract 8// (keyboard/gamepad/touch all work on day one). 9// 10// Controls (via the input layer's semantic actions): W/S or Up/Down = walk, A/D or Left/Right = turn, 11// R/F = look up/down (bound to the MENU/PAUSE bits -- the 8-action mask is fully spent; widening it 12// to 16 actions is the filed follow-up), E = break block, B = place stone. Touch d-pad works: center 13// tap = break. 14// 15// license_tier: ORIGINAL 16import "nx_syscalls.nx" 17import "nx_itrig.nx" 18import "nx_input_abstract.nx" 19import "nx_atmosphere.nx" 20import "nx_weather_lib.nx" 21import "nx_softbind.nx" 22import "nx_skeleton.nx" 23import "nx_skin_ita.nx" 24import "nx_nxa_rig_motion_context.nx" 25import "nx_nxa_anim_lib.nx" // GE31/GE23: the ONE NXA clip evaluator -- the cast's joint rows are computed HERE, not in page JS 26import "nx_morf_draw_core.nx" 27import "nx_nxa_morf_draw_admit.nx" 28import "_hdl_build/nx_entity_store.nx" 29import "_hdl_build/nx_gamesave_core.nx" 30import "nx_indoorgen_data.nx" 31// GE14a: the PURE staged-terrain core (six parameter fields -> spline -> relief/erosion). 32// Allocator-free and syscall-free, which is the only reason it can live in this wasm target -- 33// nx_worldpipe's hydrology and erosion BAKES allocate and stay NAS-side (rung GE14b). 34import "nx_worldpipe_core.nx" 35// THE ONE GEN-TIME RECIPE ALLOWLIST (2026-09-04): init_impl_v's gok9 chain, nx_world_snap and nx_game_page_emit's 36// NXGP passes all read genp_gen_ok from this lib, so an index admitted to the engine reaches the instrument and 37// the page in the same edit.

The WebGL path used to render at true 69// device resolution while this rasteriser was pinned at 480x300 and CSS-stretched to 1920 -- a 4x linear 70// upscale, which is exactly what "significantly worse" was. 71// W/H are the FRAMEBUFFER, and the renderer derives rw=W/q, rh=H/q, foc=W/(2q) -- so FOV is invariant 72// under q BY CONSTRUCTION and the adaptive controller is the thing that scales to the hardware. 73// 1920x1200 keeps the old 16:10 aspect EXACTLY, so framing is unchanged -- it is 4x the linear detail 74// and 16x the AREA of the 480x300 this replaces. 75// ★THE SAFETY PROPERTY THAT MAKES THIS NON-REGRESSIVE: at q=8 this is rw=240, rh=150, foc=120 -- 76// byte-for-byte the old default. The initial q is 8, so the first frame costs what it always did; the 77// controller only refines toward q=1 (one ray per pixel) when frames measure under 11ms. 78// ★CEILING CHOSEN FROM THE MEMORY ENVELOPE, NOT TASTE: pixels are i64 because this language has no 79// 32-bit pointer type (MEASURED: 0 hits for `as *u32` across 23,072 sources, coverage complete), so 80// the framebuffer costs W*H*8 = 18.4 MB. A 3840x2400 ceiling would cost 73.7 MB to expose a q=1 that 81// is unreachable anyway -- 9.2M DDA rays per frame is seconds, not milliseconds. Real 4K needs 4-byte 82// pixels plus SIMD, not a bigger constant here; raising W alone buys memory, not detail. 83// ★THE CEILING IS BOUNDED BY THE WASM LINEAR MEMORY, AND THAT BOUND IS NOT NEGOTIABLE BY TASTE. 84// The WAT backends size linear memory FROM THIS MODULE (2026-08-18): they read the 85// `static nx_wasm_pages_req` contract row below at emit time, so the page count has ONE 86// owner (this file) instead of the three drifting copies that shipped 192-vs-364 and 87// fail-closed the lane. (The AHEAD reconciliation that gated this: the 21 "lost" strings 88// were superseded rewords of nx_parse diagnostics, proven live by fixture.) A 1920x1200 framebuffer at O_FB needs 89// 3,590,528 + 18,432,000 = 22,022,528 bytes, i.e. 9.4 MB PAST THE END, so every render trapped with 90// "index out of bounds" and /craft went black. Shipped and caught in production 2026-08-14. 91// 1200x750 keeps the 16:10 aspect and needs 3,590,528 + 7,200,000 = 10,790,528, leaving 1,792,384 92// bytes of headroom inside the same 192 pages. It is still 2.5x the linear detail and 6.25x the AREA 93// of the 480x300 this replaced. 94// ★AND IT KEEPS EXACT PARITY WITH THE OLD DEFAULT: at Q_START=5, rw = 1200/5 = 240, rh = 750/5 = 150, 95// foc = 1200/(2*5) = 120 -- byte-for-byte the pre-change frame, so no machine is worse off. 96// WASM_MEM_BYTES below mirrors the backend's page count so nx_wasm_craft_gate can REFUSE a ceiling 97// that does not fit; the real remedy is for the backend to size pages from the module's own arena 98// rather than a constant, and that is owed. 99// ★THE RENDER CEILING IS THE PAGE'S OWN DISPLAY CAP, NOT A TASTE (operator 2026-08-17: "why these 100// arbitrary resolution rates"): the emitted page has always capped the canvas at min(98vw,1920px) -- 101// the ceiling below and that cap were TWO constants describing ONE thing, and at 1200 the render 102// ceiling silently bound first on every desktop display. Now the ceiling IS the cap (1920 wide at 103// the shipped 16:10 aspect); which fraction of it a device actually renders is decided PER DEVICE by 104// the adaptive controller against that device's own measured budget -- no resolution number below 105// this line is chosen by hand. 106const W: i64 = 1920 107const H: i64 = 1200 108const WASM_PAGE_BYTES: i64 = 65536 109// pages = ceil(CRAFT_TOTAL / page) + the previously PROVEN slack. ceil alone is 339 (339*65536 = 110// 22,216,704 >= CRAFT_TOTAL 22,216,352); the +25 pages carry forward the old configuration's 111// measured-working headroom class (~1.6MB) as the runtime/shim allowance -- honestly UNMEASURED 112// whether anything needs it, so it is kept, named, and gate T60 pins the fit while the wasm-vm 113// gate's PAINTS tooth proves the module actually runs inside what it declares. 114const WASM_PAGES: i64 = 364 115const WASM_MEM_BYTES: i64 = WASM_PAGES * WASM_PAGE_BYTES 116// MODULE-OWNED PAGE SIZING, BLOCKED AT THE ENCODER (2026-08-18): the WAT backends 117// (wat_mem_pages in nx_wasm/nx_wasm_scalararm) READ a module-declared 118// `static nx_wasm_pages_req: i64 = WASM_PAGES` and size linear memory from it -- 119// mechanism shipped and bite-proven.

The 285// per-girl hair guide simulation -- rest curves from the asset's own HSTR section, colliders FITTED from the 286// asset's own rig (VERT/SKEL/DYNA), a per-tick solver (spring-to-rest + damping + gravity + the world's wind 287// field + the girl's own motion as an inertial drag), follow-the-leader length projection alternating with 288// capsule push-out, DFTL velocity correction, and the 2-nearest-guide render weights -- lives HERE as arena 289// state. The page may do exactly two things with it: copy the asset's raw section BYTES into the scratch 290// below once at load (never a computed value), and copy the export block OUT to a GL texture each frame. 291// Every number a visitor sees on a strand is computed in this file. 292// UNITS: the NXA's bind (mesh) space, z up, integers.
