Interview with Davin Wilfrid of Future Insights

Posted · Category: Information

Davin Wilfrid – Product Director/Community Manager, Future Insights

As community manager and event emcee, Davin is in charge of keeping the party going by bringing all the cool content from Future Insights conferences to the Future Insights site.

1. How did Future Insights get its start?

Future Insights started as Carsonified conferences. The founder of Carsonified, Ryan Carson, sold his conference business to focus full time on Treehouse, a fantastic service that teaches you to code through interactive tutorials. Carsonified had produced tech conferences for years, so we’ve still got a ton of institutional memory and the great conference producers who made the Future of Web Design, Future of Web Apps, Future of Mobile, and Future Insights Live conferences a success.

2. How do you differentiate Future Insights and other similar events and conferences?

There are a few ways. First, all we do is produce tech conferences, so we spend 100% of our time researching the right content, finding the best speakers available, and planning things to ensure people get every dime of value for the price of their ticket. Second, the scope of our events tends to be larger than others. Instead of sticking people in one room for two days, we usually plan out two or three (or five, in the case of Future Insights Live) different tracks in different rooms. This gives people more options on site. Third, we professionally record every session at our events, and make them available to attendees after the fact. This way you never really miss a thing.

How to Diagnose JavaScript Errors Faster with Error.stack

Posted · Category: Information

Modern browsers like Internet Explorer 10 support for Error.stack, which enables Web developers to diagnose and correct bugs faster, especially those that are difficult to reproduce. Developers can build amazing apps with the capabilities of Web platforms that power today’s modern browsers as well as apps in Windows 8. The increasing power and complexity of these apps means developers need better tools like Error.stack for handling errors and diagnosing bugs. In this article, I’ll show you some simple debugging techniques to help save you time.

Debugging Applications

Structured error handling in JavaScript rests on throw and try/catch – where the developer declares an error and passes the control flow to a portion of the program that deals with error handling. When an error is thrown, Chakra, the JavaScript engine in Internet Explorer, captures the chain of calls that led up to where the error originated – also referred to as the call stack. If the object being thrown is an Error (or is a function whose prototype chain leads back to Error), Chakra creates a stack trace, a human-readable listing of the call stack. This listing is represented as a property, stack, on the Error object. The stack includes the error message, function names, and source file location information of the functions. This information can help developers rapidly diagnose defects by learning what function was being called, and even see what line of code was at fault. For example, it might indicate that a parameter passed into the function was null or an invalid type.

Let’s explore with an example of a simple script that attempts to calculate the distance between two points, (0, 2) and (12, 10): Read the rest of this entry »

A Complete Guide for Building HTML5 Games

Posted · Category: Information

I’m currently spending most of my time explaining to students, hobbyists, professional developers and teachers how to build games using HTML5. I then recently thought: rather than keeping all these details for small audiences, wouldn’t it be smarter to share it with you?

This article is then based on my own experience. I will probably omit some crucial things some of you may know. But it will try to update this blog post along with my own new discovers and of course based on the feedbacks you will kindly provide in the comments or via Twitter.

But why are so many people currently interested in HTML5 Gaming?

Well, simply because today, we can really use HTML5 to target multi-platforms using the same code: for desktop machines of course (with IE9/IE10, Firefox, Chrome, Opera & Safari), for iOS & Android tablets & phones and Windows 8, and its future associated millions of tablets & PC, is also warmly welcoming HTML5 Games! I then frequently see some HTML5 gaming projects ported to each of these platforms with almost no effort.

What’s more, the modern JavaScript engines performance coupled with the GPU hardware-accelerated graphics layers enable us to build great games in HTML5 with confidence.

Note: we will only talk about the <canvas> tag of HTML5 and about SVG in this article.

Canvas & SVG: 2 ways to draw on the screen

The first thing you need to understand before building your first HTML5 game is how to draw nice objects on the screen. There are 2 ways to do that and to better understand their differences, you should start by reading this article from Patrick Dengler (member of the SVG W3C Working Group): Thoughts on when to use Canvas and SVG

On my side, I’ve re-used parts of Patrick’s materials to build a 45min internal session for my Microsoft’s colleagues last year. You can watch it via this video I’ve made (using HTML5 <video> of course!): Read the rest of this entry »

Quickstart: Adding HTML Controls in Windows Store App

Posted · Category: Information

Every app needs controls, such as buttons, check boxes, and drop-down lists. Windows Store apps built for Windows using JavaScript can use two types of controls: intrinsic HTML controls and Windows Library for JavaScript controls. Intrinsic HTML controls are those controls, such as buttons and check boxes, that are a part of the HTML standard.


Here we focus on how to create and use HTML controls. The next topic, Quickstart: Adding WinJS controls and styles, describes how to create and use Windows Library for JavaScript controls.


We assume that you can create a basic Windows Store app using JavaScript that uses the Windows Library for JavaScript template. For help creating your first app, see Create your first Windows Store app using JavaScript.

What is a control?

In many application programming models, you need a control to display or interact with content. Because most HTML elements are capable of displaying content and responding to a variety of events, the distinction between a control and an element isn’t always clear for Windows Store apps using JavaScript. We refer to elements and objects whose primary purpose is to provide interactivity as controls. For a list of elements and objects that fall into this category, see Controls by function.

Adding an HTML control

You can use any HTML control in your Windows Store app using JavaScript. Read the rest of this entry »

Deft and Intuitive Character Movement in HTML5 Games

Posted · Category: Information

This article recently appeared on BuildNewGames.com, a collaboration by the teams at Bocoup and Internet Explorer. Recently, I released Empty Black, my 2D shooter/puzzler/platformer. In this article, I’ll describe how I made the player movement deft and intuitive. Play the game before you read on, so you’ll know what I’m talking about.

My general approach was to change something, then try it out. I took the ideas for adjustments from several sources.

One. I examined the parameters affecting the movement of the player characters in other 2D platformers. Is the floor slippy? What is the ratio of sideways movement to jump height? Does the character accelerate as it moves? Is the character’s jump height affected by the length of time the player holds the jump button? Is the character slowed when it bumps into a moveable object?


Two. I examined the unusual behaviours of the player characters in other 2D platformers. Super Meat Boy makes the character leap away from the wall automatically when wall-jumping. Spelunky lets the character pull himself up and over ledges. In Castlevania, the character can do an extra jump while in mid-air. Three. I got people to play test. Kemal told me that the character movement should be effortless. Specifically, if the character hits a wall near the top, it should slip up and over. Ricky told me it was weird that the player had no control over the height of the character’s jump. He showed me how, when hopping over an obstacle in a room with a low ceiling, he bumped his head. Ricky also pointed out the jarring effect of the initial slow down of the character when it lands after a jump. Everyone told me that airborne movement was too sensitive. Everyone told me that wall-jumping was too finicky.

Four. I read pieces written by programmers about their character movement algorithms. These pieces were mostly confined to short comments, rather than in-depth analyses. Hence, this article.   Read the rest of this entry »

How to Make Sprite Animations with HTML5 Canvas

Posted · Category: Information

This article recently appeared on BuildNewGames.com, a collaboration by the teams at Bocoup and Internet Explorer. It has been authorized to be published on WebAppers.

Sprite Fundamentals

I’ve always loved web games; they’re just fun to make, easy to code (mostly), and there’s something really nice about how accessible a game is when the user just has to click a link to start playing.

Ajax and moving dom elements around made for some fun, but limited in what kind of experience you could create. For game developers, things are changing, and quickly. HTML5 is introducing a bunch of new options for game development purely in the browser, and the browser vendors are competing hard to be the best platform for the new standards.


So from a game developer’s perspective everything is going in the right direction: 2D  and 3D hardware-acceleration, high-performance javascript engines, integrated debuggers and profilers, and, probably most importantly, browser vendors who are actively racing to be the best for serious game development.

So the tools are becoming usable, the browsers capable, and the vendors are listening, we can just go make awesome games right? Well, mostly.

HTML5/Javascript game development is still early, and there’s pitfalls to avoid, as well as choices to make on which technology to deploy.

In this article I’ll run through some of the choices to be made developing 2D games, and hopefully give you some ideas for developing your own games using HTML5.
