stackLayoutfunction

Where the cards of a stack lie, from neat to messy, the same every time for the same seed: the cards under the top one, bottom first, at most depth of them, as the top card is the live one and lies square. A card's place depends on its number from the bottom, so a card put on top moves none of those under it.

The idea and the three parameters (messiness, seed, depth) come from toranpu's pileLayout (github.com/johnmorrisdotca/toranpu, src/ui/layout.ts, MIT). This is written again here for a stack that has a true thickness: a card's height is not faked by moving it down the page, so only the nudge and the turn are laid out.

import { stackLayout } from "@johnmorrisdotca/fuda-cards";

function stackLayout(count: number, options?: StackLayoutOptions): StackPlace[]

import { stackLayout } from "@johnmorrisdotca/fuda-cards";

const same = JSON.stringify(stackLayout(52, { seed: 7 })) === JSON.stringify(stackLayout(52, { seed: 7 }));
console.log(same, stackLayout(1).length, stackLayout(52).length); // true 0 10

true 0 10
