Jump Point Search This is the final article in my three-part look at symmetry reduction algorithms for speeding up pathfinding on uniform-cost grid maps. Recapping the story so far:Part one introduces the notion of path symmetry: a property of uniform-cost grid maps which can significantly slow down search. Part two discusses Rectangular Symmetry Reduction (RSR) [2]: a simple yet effective preprocessing algorithm that eliminates many path symmetries by decomposing a grid map into a set of empty rectangles. In this article I describe Jump Point Search (JPS) [3]: an online symmetry breaking algorithm which speeds up pathfinding on uniform-cost grid maps by “jumping over” many locations that would otherwise need to be explicitly considered. JPS is faster and more powerful than RSR: it can consistently speed up A* search by over an order of magnitude and more. Unlike other similar algorithms JPS requires no preprocessing and has no memory overheads.

Try eating a hotdog that fast – though I swear I’ve seen our dog go through a beef sausage in under 100 milliseconds. If you want your game to run at 60 frames per second, 16 milliseconds is all you have to get everything done: moving bullets around, creating new entities, drawing sprites, checking collisions, tracking and changing states, handling input and playing sound. Whatever happens regularly in the main game cycle needs to operate as efficiently as possible. Even at a lower-performing frame rate of 30 per second, you’ll still only have 32 milliseconds to get everything done.

C++ Game Programming Tutorial by Forest J. Handford In this chapter we will develop a Hangman game. To start off this chapter, we are going to learn about the ++ and the -- operator. Coding an Image Thumbnail Hover Magnify Effect with jQuery I have run into a number of simple effects to generate image magnification. You can sometimes find this on e-commerce websites for product images when you hover onto the thumbnail and a bigger zoom effect will display. This is a great technique no matter what type of website you have.

A* Search Algorithm in C# - Cody Stebbins' Blog - Quora Just a heads up I haven't tested this code in about 3 years. I'll be writing a follow up on how to implement A* in Ruby soon (and hopefully in C if time grants), but for now the concepts apply and the code can help illustrate the point. In this post I’ll be covering my C# implementation of the A* Pathfinding algorithm. A* is an algorithm used to efficiently plot the shortest traversable path between two points. This is commonly used in 2D grid based games such as Pacman. It uses a best first search and finds the least cost path using a heuristic formula. Backbone or Angular or Ember? Here is my choice and why » { 100PercentJS } I’ve spent the last year neck deep in the main MVC / MV* whatever frameworks for Javascript. It was a very hard choice to pick a favorite and stick with it. I started out with Backbone, moved on to Angular and finally settled on Ember. This convoluted process is the reason I haven’t blogged in a few months, I really had to pick what client-side framework to blog about. This is my reasoning:

Bryntum Overview Siesta is a JavaScript unit testing tool that can help you test any JavaScript code and also perform testing of the DOM and simulate user interactions. The tool can be used together with any type of JavaScript codebase – jQuery, Ext JS, NodeJS, Dojo, YUI etc. Using the API, you can choose from many types of assertions ranging from simple logical JS object comparisons to verifying that an HTML element is visible in the DOM. It comes in two versions: Lite and Standard.

free game graphics It is once again time for a prototyping challenge! The rules are the same. You are an elite programmer that wants to make something fun without spending ten years in art school learning how to draw stick figures. I provide some easy-to-use graphics and an intriguing game design for you to riff upon. Send me the links to your masterpieces and I'll post them for folks to enjoy and critique.

The Benefits of Working on Freelance Projects I often read about designers who cannot stand freelancing yet continue to use this path for solid income. I suppose there is nothing wrong with hating your job, but some designers actually enjoy freelancing. It is not a career choice that many people would keep for decades. But it does offer a unique lifestyle of working on various projects and studying new trends. In this article I want to present a few ideas arguing the benefits of working on freelance projects. Both designers and developers creating websites have the opportunity to earn real livable money without answering to one specific bossman.
