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 🙏

Example

View demo in www/ folder and src/app.js for source code.

See dota-interactive-map for another application.

Usage

var VisionSimulation = require("dota-vision-simulation");
var worlddata = require("dota-vision-simulation/src/worlddata.json");
var options = {radius: 1600};

var vs = new VisionSimulation(worlddata, options);
vs.initialize(mapImageDataPath, onReadyCallback);

worlddata - world dimensions, {"worldMinX":-8288,"worldMaxX":8288,"worldMinY":-8288,"worldMaxY":8288}

options - Optional settings object.

  • radius - Initial radius in grid tiles. Default: 1600 / 64

Methods

initialize(mapImageDataPath, onReadyCallback) - Starts the vision simulation.

  • mapImageDataPath - path to map data image, "www/map_data.png"

  • onReadyCallback(err) - callback executed when map data is loaded and vision simulation is ready. Returns an error object if an exception occurred.

updateVisibility(gX, gY, radius) - Executes the FOV calculation and update the lights property on the VisionSimulation object. (gX, gY) is a grid coordinate representing a 64x64 tile in the 260x260 world grid. radius optional.

toggleTree(gX, gY) - Toggles tree cut down state at (gX, gY) in grid coordinates.

setRadius(r) - Sets default radius.

WorldXYtoGridXY, GridXYtoWorldXY, GridXYtoImageXY, ImageXYtoGridXY, WorldXYtoImageXY - Functions for converting between world, grid, and image coordinates.

key2pt, xy2key, xy2pt, pt2key - Functions for converting between (x, y), {x: x, y: y}, and "x,y" coordinate formats.

isValidXY(gX, gY, bCheckGridnav, bCheckToolsNoWards, bCheckTreeState) - Check whether grid coordinate is a valid position or not. bCheckGridnav, bCheckToolsNoWards, bCheckTreeState optional.

Data

worlddata.json and map_data.png come from dota-map-coordinates
