Simple Math for 2D Shapes

import { Map2D } from "https://deno.land/x/simple_shape_math@v1.0.0/containers2d.ts"

// Start by creating a new Map2D()

const grid = new Map2D();

// Add some values to it
grid.set({ x: 123, y: 321 }, { r: 0, g: 192, b: 40 });
// ^ The key is (123, 321) and the value is the object { r: 0, g: 192, b: 40 }.

// Keys can be specified with just their x, y number values by calling `setXY`
grid.setXY(123, 321, { r: 255, g: 255, b: 255 });
// ^ Replaces the previous value set

// Iterate through the Map2D values with the common JS aproaches:
const allValues = [...grid.values()]; // [{ r: 255, g: 255, b: 255 }]

for(const [x,y] of grid.keys()) {
  console.log(x, y);
}

for(const [[x, y], value] of grid.entries()) {
  // Do something with both keys and values
}

import { Set2D } from "https://deno.land/x/simple_shape_math@v1.0.0/containers2d.ts"

// Start by creating a new Set2D()

const unique = new Set2D();

// Add some values to it
unique.add({ x: 123, y: 321 });

// Values can be specified with just their x, y numbers values by calling `addXY`
unique.addXY(1337, 7331);

console.log(unique.has({ x: 123, y: 321 })); // prints "true"

// Iterate through the Set2D values with the common JS aproaches:
const allValues = [...unique.values()];
// ^ [{ x: 123, y: 321 }, { x: 1337, y: 7331 }]

for(const [x,y] of unique.keys()) {
  console.log(x, y);
}

for(const [[x, y], value] of unique.entries()) {
  // Do something with both keys and values
  // [[x, y], { x, y }]
}

import { Vector2D } from "https://deno.land/x/simple_shape_math@v1.0.0/vector.ts"

const v1 = new Vector2D(); // Creates a (0, 0) 2d point
const v2 = new Vector2D(123, 123); // Creates a (123, 123) 2d point

console.log(v1.isEqual(v2)); // prints "false"

const v3 = new Vector2D(100, 100); // Creates a (100, 100) 2d point

// Check if v3 is in the same line as v1 and v2
console.log(Vector2D.isBetween(v1, v2, v3)); // prints "true"
