A web game written in ES6 syntax and HTML5 features, such as Module, Canvas.
You can get a specific impression of the ES6 syntax, HTML Canvas Related API and Webpack simple config through this project.
Learned from Meth Meth Method On Youtube by @Meth Meth Method . Also recommend this channel strongly for you!
Many thanks to the author @pomler, learned a lot from him.

At first, personally I think good code is self documenting, the code of this project is semantic. The class name, variable name can express themselves. Only read the source code you can understand the main logic of this game.
Let me introduce the main logic:
- This game is start from
es6-mario/public/js/main.js, in this function, each Entities(Like mario, goomba etc) are created. And theMain Loopstart:
const timer = new Timer(fps);
timer.update = function update(deltaTime) {
level.update(deltaTime);
camera.pos.x = Math.max(0, mario.pos.x - 100);
level.comp.draw(context, camera);
};
timer.start();This is the core of game, the three lines are responsible for update the entity status, move the camera, draw every layers.
- Update the entity
This part start from level.update(deltaTime); in the main loop, then step into the update() method in public/js/Level.js .
update(deltaTime) {
this.entities.forEach(entity => {
entity.update(deltaTime, this);
});
this.entities.forEach(entity => {
entity.finalize();
this.entityCollider.check(entity);
});
this.totalTime += deltaTime;
}Here, this method invoke each entities' update method, calculate the status (pos, collision etc) of them.
- Move camera
This function is cooperate with the draw layers function, after main loop update the pos of camera, each layer will update itself according to the pos of camera.
For example, in /public/js/layers/background.js, every time it drawBackgroundLayer, the exact pos of background layer will move according to the pos of camera.
return function drawBackgroundLayer(context, camera) {
const drawWidth = resolver.toIndex(camera.size.x),
drawFrom = resolver.toIndex(camera.pos.x);
const drawEnd = drawFrom + drawWidth;
redraw(drawFrom, drawEnd);
context.drawImage(
buffer,
-camera.pos.x % 16,
-camera.pos.y);
}- Draw layers
The code of his part is mainly under the /public/js/layers. There are background layer, camera layer, collision layer, sprite layer, dashboard layer. As the name of each layers, it control the painting of itself.
In here: https://www.youtube.com/watch?v=I1RTsqUz-t0&t=903s , you can get a directly demo.
- Input, Timer, Entity Trait, Physical Effect and so on
In addition to the function above, this game also have many other unique function you deserve to learn about.
Besides, If you really intend to learn this project systemically, I **strongly recommend the series of the original author: https://www.youtube.com/watch?v=g-FpDQ8Eqw8&t=2s **。
- Regularly Clean up your code
By split the implementation and declaration with module syntax, build a Class.
- Es6 Syntax
- <1> Module
<script type="module" src="/js/main.js"></script>
import {loadLevel} from './loader.js'
import {loadBackgroundSprites, loadMarioSprite} from './sprites.js'-
