TsunagiView型

A BIG BOARD LOOKED AT THROUGH A BOX: from 10×10 up, a phone's cells are smaller than a thumb, so the board is drawn up to three times the box's width and looked at through it, zoomed and moved by a pad of buttons, the wheel and (while a line is dragged) the box's edge, never by scrolling the page. This is only the arithmetic of the view; mountTsunagi does the rest.

A view is a zoom (1 is the whole board fitted to the box) and where the board's top left sits in the box, which is never past the box's own edges.

import type { TsunagiView } from "@johnmorrisdotca/tsunagi/play";

type TsunagiView = {
    zoom: number;
    x: number;
    y: number;
};

import type { TsunagiView } from "@johnmorrisdotca/tsunagi/play";

const value: TsunagiView = {zoom:1,x:0,y:0};
console.log(value);

{ zoom: 1, x: 0, y: 0 }
