This is an ongoing work-in-progress port of the decompilation of original Nintendo game, Super Mario 64, to native Javascript (no emulation or web assembly). The project involved creating a Javascript WebGL port of N64 Fast 3D Renderer, originally implemented with OpenGL in C. This project also includes the development of online mass multiplayer versions of sm64js and other custom multiplayer game modes.

Build instructions — Windows, Mac, or Linux

# Clone the source code git clone https://github.com/sm64js/sm64js.git && cd sm64js # Install node packages npm install # Launch wepback dev server npm run start

# update folder (be inside sm64js) git pull # Launch server npm run start

You should now be able to access the website with the game from a web browser by typing «localhost» into the address bar.

Build instructions With Docker — Windows, Mac, or Linux

# Create and start lightweight docker container with NodeJs docker run --name mySm64JsServer -dp 80:80 node:13 tail -f /dev/null # Connect to the docker container's shell docker exec -it mySm64JsServer /bin/sh # Install additional prerequisites apk update && apk add git # Clone the source code git clone https://github.com/sm64js/sm64js.git && cd sm64js # Install node packages, build, and serve npm run build npm run serve

You should now be able to access the website with the game from a web browser by typing «localhost» into the address bar.

Neat gLinker commands you can run in the console

Because of a good portion of the game existing under the gLinker object within the window object, you can manipulate these portions of code to make certain things happen.

Drain the Castle Grounds moat:

const gEnvironmentRegions = gLinker.ObjectListProcessor.gEnvironmentRegions gEnvironmentRegions[6] = -800 gEnvironmentRegions[12] = -800

gLinker.LevelUpdate.gMarioState.key = value

With this, you can make Mario fly, go fast, and a lot of other things.

• OpenGL Implementation of a 3D renderer for the Nintendo 64’s graphics (For this project, it was re-implemented in Javascript and WebGL)

#Mario Mario.js is a clone of Super Mario Bros. for the Nintendo Entertainment System, implemented in Javascript. It implements a hand-built game engine using the HTML5 Canvas.

Disclaimer: This project is for demonstration only. If you really want to play Mario, please do it on a console. The graphics, sounds, and original design of Super Mario Bros. are all owned by Nintendo.

##Game Flow The main loop tries to render at 60fps. Each frame, we go through a few steps to update the game, and then render.

First, we get the controls. Depending on what the player is pressing, we make some changes to the player object.

Then, we update each entity, and the general game state. Entities are game objects which have data about their position, movement, collision boxes, and sprite, as well as functions for updating that state, and rendering to the canvas.

Scrolling is implemented using a viewport position that increases as Mario travels to the right. We only render or do calculations on objects that are close enough to the left edge of the screen. As in the original game, enemies become active slightly before they appear on screen.

The update function contains all of the logic for mutating the object’s state without data from other entities. Once each object has updated, we check collisions. Independent movement, such as coins popping out of blocks, or Mario grabbing the flag and running out of the stage, are controlled here.

##Collision For obstacles such as walls, the ground, and the various blocks, they are indexed by their position in the game, so each entity only needs to check the area around itself for collision with those.

Then, each entity iterates through the other active entities to determine collision with moving objects, calling functions to update positions and state as appropriate.

The player object only checks collision with terrain. Enemies and items check their collision with the player and tell it how to update.

Note that collision boxes are separate from the display position of the entity’s sprite. This was the case in the original game as well. Generally speaking, making the collision slightly more generous improves game feel.

##Rendering Once everything is in its proper place, we call each object’s render function. Since the canvas doesn’t implement a z-axis, the layering effect is handled entirely by rendering the objects in this order:

Background Props Items Enemies Projectiles Terrain Player Pipes

Each object in the game holds a reference to a sprite object. Sprites identify which slice of what image to use, and data about which other frames in the sheet are part of the current animation, and how fast it should animate.

Sprites assume that the entire animation is contained on a single row of the sheet. For the few exceptions, we force the sprite into the correct frame in the entity’s update function.

Similarly, entities which need to face left and right replace the image reference in their sprite object with a flipped counterpart.

#Level Generation Each level object is created with references to the sprites to use for each type of object in the game. In this case, there are only a few tile sets, so individual levels could inherit from level subclasses for overworld, underground, castle, etc.

The level is constructed using a series of calls to functions that populate the tables of objects in the game world.

Pipes work by setting up the animation, and then calling a function to load the new level. Exit pipes use the same code for moving Mario, but with another callback that puts the player into position after setting up the stage.

Known Bugs and Features to Come

-Scaling sprites makes them appear with awkward borders. Some fiddling helps this (as you can see in the live version), but they are still not quite perfect. -A rare case that causes invincibility from getting hit to never end. -Goombas don’t animate in sync with each other. -Sometimes goombas can get stuck inside each other. I’m not entirely sure what causes this. -Some sounds might not work due to format compatibility, especially in IE. Yes, IE doesn’t support Microsoft’s own file format. Really.

All of the features to be implemented are the actual features of the game! Namely, a score counter, more types of enemies, and 1up mushrooms.

Also, it should be possible to scale the game to any size, although in order to preserve sprite dimensions changing the actual size of the play area will be necessary for widescreen. For now, the game is rendered in 768×720.

Beyond that, it would be nice to recreate the original game in even more detail, including the precise replication of the 21-frame rule, and glitches such as well-ejection errors, alternate pipes, and various simultaneous left+right input shenanigans.

Code Super Mario Bros. in JavaScript

Create a Super Mario game in vanilla JavaScript from scratch.

This project is built during my YouTube series Code Super Mario in JS; a series by my channel Meth Meth Method.

• Clone repository.
• Run npm install .
• Run npm start .
• Go to http://localhost:5000 .

TypeScript in-browser editor by @AFE-GmdG

Please contribute if you see something wrong, but I can unforunately not merge your PR directly into master as I use Git commits as a script for creating the tutorial and commits out of sequence would throw me off.
