Moving Squares

import { Rectangle, Scene, World } from "https://deno.land/x/caviar/mod.ts";

Perlin Noise

Texture Sprites

import {
  PICO8,
  Scene,
  TextureSprite,
  World,
} from "https://deno.land/x/caviar/mod.ts";

class Game extends Scene {
  test = new TextureSprite(this, 0, 0, {
    data: [
      "..9..9..",
      "..9999..",
      ".AAAAAA.",
      ".A1F1FA.",
      ".AFFFFA.",
      ".FEEEEAA",
      ".EEEEEEA",
      "..E..E..",
    ],
    pixelWidth: 32,
    pixelHeight: 32,
    palette: PICO8,
  });

  setup() {
    this.addChild(this.test);
  }
  update() {
    this.test.setX(this.test.x + 10);
  }
}

const world = new World({
  title: "Texture Sprite Example",
  width: 800,
  height: 600,
  resizable: true,

await world.start();

As Caviar uses the Deno FFI, you will need to add the flags --allow-ffi --unstable to run the programs. You can also add other flags to skip the permissions check the Deno does. An example of starting the program in Deno with all these flags is

deno run --allow-ffi --allow-env --allow-read --allow-write --allow-net --unstable test.ts
