- Directional toon lighting component on entities. (extension of the shadow light source) The shadows were doing this anyways, but with extremely bad stairstepping. Now it smoothly blends into the shadow. - Greatly reduce shadow acne via the above and a larger bias. - Respect culling mode for each model. - Two sided shading for course models. - Disable alpha for water that does not use it. - Only GBA Sky Garden's skybox receives shadows now. - Custom light positions for some maps. (you can guess which) |

mkjs
mkjs is an experimental javascript engine reimplemention of Mario Kart DS. Users of the application must provide their own Mario Kart DS ROM, dumped using a DS or 3DS. This project exists for entirely educational purposes.
If you have a ROM of MKDS available, you can give mkjs a shot here: http://rhy3756547.github.io/mkjs
Purpose
I started working on mkjs a few years ago to get a better grasp on a lot things, mainly for fun. Here are the key factors:
- WebGL game engine with no dependancies. Entirely written using vanilla Javascript ES5. (will not accept contributions using libraries!)
- (exception is GLMatrix, which is required for matrix and vector operations)
- Entirely implement readers for NDS file formats, and ways to utilise them in an actual game environment.
- SSEQ (midi) music and sfx player using Web Audio API features. Supports 3D sound, and used to support doppler...
- Custom simple collision engine with swept sphere collision against quadtree partitioned triangle collision meshes. Performs well enough in javascript, but could likely be faster.
- Attempts to replicate the perfect physics and feeling of this beautiful game, through format and physics reverse engineering.
- Very clean "class" structure in ES5. ES6 port would be welcome, I might do that at some point.
- Works on many platforms, including iOS at 60 fps!
Current Features
The base game mostly works. A lot of the grunt work is done - the current setup shows a good prototype of the game working.
- Nitro filesystem management for real .nds files, allowing a ROM to be provided with no changes.
- Loads and displays all courses (including battle) in some playable form. Textures, texture animations are intact.
- Functional Kart vs. World physics, using kcl files for courses.
- Work in progress Kart vs. Moving object physics (see Tick Tock Clock, Bowser's Castle DS)
- Functional AI karts that follow the same waypoints as MKDS AI. (battle and race AI modes)
- Content system for work in progress course objects, eg. routed car obstacles, moving platforms.
Possible Future
- UI engine
- Race Logic (checkpoints, lap count, lap tracking, race completion...)
- All course obstacles (enemies, bridge in delfino)
- Items & damage
- Particle effects format reader and renderer (no idea how these formats work).
- Custom Menus
- Battle Mode & Mission Mode
- Multiplayer (custom courses? >8 players?)
- Lots of bug fixes for collisions and format readers!
Multiplayer
While multiplayer using a Websockets server is semi-functional, it is very simplistic and only exists for testing purposes. A future implementation would ideally connect to peers using WebRTC rather than connecting through a central server.
