micro-racing

multiplayer 3D isometric racing game written in WebGL 2.x. Steering(both): WSAD / Arrows.

Live demo: https://micro-racing.herokuapp.com/ (it uses free server so it can be really slow)

Gameplay

Todo

• [ ] Improve client side prediction
• [ ] Improve overall performance of server
• [ ] Improve controls

Installation

Development mode (running at http://lvh.me:3000):

yarn install
yarn run develop

Production:

yarn install
yarn run build:production

Features

• Client side prediction
• High performance isometric engine using WebGL 2.x
• Neural networks trained using evolution algorithms
• Function precompilation in stuct-pack deserializers
• Physics engine
• Optimistic forms

Goals

• Use monorepo, separated logic
• Create tiny matrix math library
• Create 3D isometric WebGL 2.0 functional wrapper(it should handle depth sorting and other stuff)
• Car steering logic (using Marco Monster approach)
• Procedural generated racetrack
• Bots using Neural Network for AI(see neural-cars)
• Multiplayer

Parts

Neural Network Implementation

forward propagation: https://github.com/Mati365/micro-racing/blob/master/src/packages/neural-network/src/unsafe/forwardPropagate.js

backward propagation: https://github.com/Mati365/micro-racing/blob/master/src/packages/neural-network/src/unsafe/backwardPropagate.js

evolution population train generation: https://github.com/Mati365/micro-racing/blob/master/src/packages/neural-network/src/genetic/forkPopulation.js#L70

Quad Tree

implementation: https://github.com/Mati365/micro-racing/blob/master/src/packages/quad-tree/src/index.js

Quad Tree handles multiple moving objects as list, stores only static objects
