timetocode / developer-console.coffee

Created April 10, 2013 01:13

add console-like functionality to an html input, while staying decoupled follows a node.js module.exports style, so something like browserify is required before this console can be used as client-side javascript

	# developer console
	inputEle = null # the console's Prompt (an html input)
	dispEle = null # the console's output (a div, span, etc)
	submitAction = null # function to run on the input
	enabled = false

	exports.enable = () ->
	# ensures html elements have been specified
	# ensures that the console is not already active
	if inputEle && dispEle && !enabled

timetocode / lagCompensation.js

Last active March 15, 2019 03:14

Lag compensation of a player's attack, using a historical stack of quadtrees and "rewinding" relevant entities stored in the quadtrees to the position they were at in the recent past (as decided by the player's ping).There is a SIGNFICANT oddity to this code, which is that quadtrees used for collisions are point quadtrees. Because of this, the i…

	// a fat hitbox around the player considered the 'relevant' area for a collision
	var hitArea = new AABB({x: player.x, y: player.y}, { x: 54, y : 54})
	var actualHitArea = new AABB({x: player.x, y: player.y}, { x: 36, y : 36})

	// how behind the player is, in server time
	var delay = player.ping + (1000 / player.tickRate)
	var tickLength = 1000 / TICKS_PER_SECOND
	var ticksAgo = Math.floor(delay / tickLength)
	var tickPortion = (delay % tickLength) / tickLength

timetocode / Twitch.tv is channel live api query

Last active December 31, 2015 14:09

Query Twitch.tv to see if a channel is streaming! Assumes a div of id = 'streaming' to put the results, and a couple css classes to style the results.

	<script type="text/javascript">
	$(document).ready(function() {

	// your twitch channel name
	var twitchName = 'yourchannelname'

	// an element on your page to put the widget into
	var elementSelector = '#streaming'

	// HTML to display while waiting for data

timetocode / body code

Last active October 24, 2016 00:30

A script to display if a certain channel is currently live on Twitch.tv. To use this script on your website, paste all of the code from the "head code" into the <head></head> tag of webpage. Then paste the one line from "body code" wherever the widget should appear.

Entity interpolation

	/* Entity Interpolation
	this code occurs within the draw loop for an entity
	this.x and this.y represent the most recently received server position of
	the entity -- though i don't ever intend to use it for drawing

	when an update is received (roughly every 50ms in my particular game) this.x and this.y get
	pushed into previousState.x and previousState.y

	i also continue sloppily onwards to previousPreviousState.x, but I've removed that code

timetocode / Entity.js

Last active February 9, 2017 04:50

An example of extending a prototypical game Entity to have different functionality (via adding functions to the prototype) in its server environment than on the game client.

	// a simple game entity having a name and positional data
	function Entity(name) {
	this.name = name
	this.x = 0
	this.y = 0
	this.speed = 5
	}

	module.exports = Entity

An example of procedurally generating a cloudy pattern out of hand typed octaves of simplex noise. There may be an error in here, I can't quite remember if this is what the end image should look like or not. I feel like the darks should be darker and the lights lighter, but either way this is the general idea. The traditional approach is to writ…
