original JavaScript game engine

Bits and pieces of original JavaScript 2D game engines. All written myself in vanilla JS, no libraries. Also somewhat old, if I come back to it there are things I would do differently now.

• Engine

  

  Raptor Quest (WIP demo)

  (Warning: features sound) A free-roaming platformer written from scratch in vanilla ES6. Includes a flexible component-based architecture, support for multiple scenes with async loading, tile-map levels, momenutum-based physics, an edit mode, and a few more bells and whistles.

• Math

  Coolgebra

  A performant, expressive JavaScript API for complex vector and matrix operations.

• Game

  

  Raptor Run

  (Warning: features sound) A basic little "infinite flapper" HTML5 game about a scientifically-accurate feathered velociraptor. Yes, they had feathers and wings, folks!

• Engine

  

  Top-Down Adventure Game (WIP Demo)

  Early attempt at a top-down action/adventure game engine. Features normal-mapped dynamic lighting on the main character but it's CPU-based and therefore kinda slow on some devices. Also subtle natural physics including inertia, collision, and wall "sliding."

• etc.

  

  2.5D terrain

  Experimental 2D environment utilizing hand-painted normal maps to simulate 3D terrain. Aka a technique for making 3D terrain when you know how to paint but not how to model.

• WebGL

  Particle effects

  Experiments with stateless, GPU-based flame, liquid, and smoke effects.

• WebGL

  

  Dynamic sprite lighting

  Buttery-smooth GPU-based lighting in WebGL using hand-painted normal maps. Big upgrade over the CPU-based lighting in my current top-down game demo. The light follows your mouse or touch.

• 3D

  

  Fun with WebGL

  Beginner dabbling with WebGL. A spinnable, lit, texture-mapped cube in different environments. Placeholder photos and rock texture not by me.
