MineChunk

source

type MineChunk

One 64x64 tile of the world holding the revealed / flagged bitmaps. Only touched tiles ever allocate - the board is effectively infinite.

MineWorld

source

type MineWorld

Deterministic, effectively infinite minesweeper world.

Mine positions are derived from mine_cell_hash(x, y, seed), so nothing about the mines is stored: given the same seed and density every client computes the exact same board, which is what makes the shared / replayable variant nearly free to synchronise.

TerminalLine

type TerminalLine

DOMAIN_SIZE

source

let DOMAIN_SIZE : Int

The world is a bounded domain of DOMAIN_SIZE x DOMAIN_SIZE tiles holding TARGET_MINES mines in total (the quantified identity of the shared field). Outside the domain there are no mines at all.

MINES_THRESHOLD

source

let MINES_THRESHOLD : UInt64

Calibrated threshold: the domain contains EXACTLY TARGET_MINES mines at this value. Counting all 655,360,000 tiles through the hash above gives 100,000,000 exactly (scratch/verify_mine_count.py; the same number comes out of cmd/mines_calibrate). Never change it casually - it is part of the quantified identity of the shared world.

Verifying this is easy to get wrong: an earlier version of the checker hashed mix64(x ^ seed) instead of mix64(x * GOLD ^ seed) and reported 100,014,855 for this same constant. Cross-check any counter against the exact big-integer reference in scratch/probe_window.py on a small window before trusting a full-domain number.

TARGET_MINES

source

let TARGET_MINES : Int

gallery_step

source

fn gallery_step(comp_id : String, mouse_x : Double, mouse_y : Double, mouse_down : Bool, scroll_dy : Double, vp_w : Double, vp_h : Double, text_input : String, keys_pressed : Array[String], keys_released : Array[String], mod_flags : Int, mouse_secondary_down? : Bool) -> @LING71671/moon-egui/src/draw.DrawList
DrawList

Native MoonBit Component Showcase Frame Entry Point. Evaluates native widgets and returns pure @draw.DrawList to JavaScript.

get_cam_x

source

fn get_cam_x() -> Double

get_cam_y

source

fn get_cam_y() -> Double

get_gallery_cursor

source

fn get_gallery_cursor() -> String

get_gallery_status

source

fn get_gallery_status() -> String

get_grid_dim

source

fn get_grid_dim() -> Int

get_logo_color

source

fn get_logo_color(dim : Int, col : Int, row : Int) -> @LING71671/moon-egui/src/color.Color
Color?

get_selected_id

source

fn get_selected_id() -> Int

get_state

source

fn get_state() -> BenchmarkState

get_studio_cursor

source

fn get_studio_cursor() -> String

get_visible_cells

source

fn get_visible_cells() -> Int

get_zoom

source

fn get_zoom() -> Double

is_magnetic_repel

source

fn is_magnetic_repel() -> Bool

is_show_studio

source

fn is_show_studio() -> Bool

is_wave_pulse

source

fn is_wave_pulse() -> Bool

mines_calibrate_threshold

source

fn mines_calibrate_threshold(target : Int) -> UInt64

Binary-search the smallest threshold whose domain holds at least target mines. Runs once at development time (cmd/mines_calibrate).

mines_count_for_threshold

source

fn mines_count_for_threshold(threshold : UInt64) -> Int

Count mines over the whole domain for a given threshold (calibration).

mines_density_percent

source

fn mines_density_percent() -> Double

The density the board is built with, as a percentage: a tile is a mine exactly when the top 32 bits of its hash fall below the calibrated threshold, so the threshold IS the per-tile mine probability. Multiplying it by the domain gives 100,003,690, against an exhaustively counted 100,000,000 - a 0.40 sigma draw.

mines_domain_tiles

source

fn mines_domain_tiles() -> Int

Total tiles in the shared domain: 25,600 x 25,600 = 655,360,000.

The number is the point of the demo and also its least believable claim, because it cannot be seen. The viewport holds a few thousand tiles at any zoom the board stays legible at, so "100 million mines" and "1 million mines" render identically. Anything that makes the scale visible - the overview map and the coverage figure - reads from here.

mines_is_mine_raw

source

fn mines_is_mine_raw(x : Int, y : Int) -> Bool

Raw hash classification without world state - the calibration tool and the sampling test both count through this.

mines_step

source

fn mines_step(mouse_x : Double, mouse_y : Double, mouse_down : Bool, mouse_secondary_down : Bool, pan_dx : Double, pan_dy : Double, zoom_delta : Double, action_switch : Int, vp_w : Double, vp_h : Double) -> MinesFrame

Per-frame entry point of the standalone minesweeper page. The host only feeds pointer / wheel / button state - everything else (procedural board, cascade, rendering) lives in this deterministic core.

step

source

fn step(mouse_x : Double, mouse_y : Double, mouse_down : Bool, pan_dx : Double, pan_dy : Double, zoom_delta : Double, switch_mode : Int, vp_w : Double, vp_h : Double, text_input : String, keys_pressed : Array[String], keys_released : Array[String], mod_flags : Int) -> FrameOutput

Core benchmark frame update function supporting 128x128, 256x256, 512x512, 1024x1024.

Input crosses the JS boundary as primitives - pointer, the text typed this frame, the named keys pressed and released this frame, and a modifier bitmask - and host_input.mbt turns them into the library's events.

studio_step

source

fn studio_step(cur_w : Double, cur_h : Double, mouse_x : Double, mouse_y : Double, mouse_down : Bool, scroll_dy : Double, text_input : String, keys_pressed : Array[String], keys_released : Array[String], mod_flags : Int, mouse_secondary_down? : Bool) -> @LING71671/moon-egui/src/draw.DrawList
