Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

box2d-player

A small module that handles creating a player that can jump with Box2dweb. Handy for prototyping other parts of a physics-based game - if you're developing your own thing, you'll have better results writing something from scratch!

Installation

npm install box2d-player box2dweb-commonjs

Usage

b2Player = require('box2d-player)(Box2D)

Pass box2d-player your Box2D object and get back a player class in return.

var b2Player = require('box2d-player')(require('box2dweb-commonjs').Box2D)

player = b2Player(world[, options])

Creates a player instance, with its body attached to the world. Takes the following options:

  • data: the user data to attach to the body. Defaults to null
  • position: the position to create the player at. Defaults to {x:0,y:0}.
  • jumpHeight: the impulse to apply upwards when jumping. Defaults to 10.
  • body: a body you can use for the player - a default body will be created if not supplied.
  • fixture: a fixture you can use for the player - otherwise, a circle will be created for you.

player.jump()

Triggers a jump provided there's a physical body below the player and it's not moving upwards.

Right now you'll still need to control horizontal motion manually - you can do this by changing the value of the player.body.m_linearVelocity.x property.
