How I Hand-Rolled MVC for a JavaScript Game and It Was Awesome

What was left was anapplication handsomely structured around the MVC pattern, and compared to theinitial version I hacked together, the logical separation into model andpresentation code is the biggest single design improvement. Drag cards to move them between the waste pile, the seven tableau columns (at the bottom), and the four foundations. You can also double-click cards instead of dragging them to a foundation.

Should we begin doing so in the future, we will update this Privacy Policy. Drag cards to move them between the ten tableau columns at the bottom. The goal is to move all cards to the eight foundations at the top.

Card Model

The models hold the game state and implement the game (domain) logic. Ideliberatedly kept the models isolated from the rest of the application, so thecode doesn’t know about the controllers or views, and also doesn’t need a DOM.This has made the code much more maintainable. I’m also hoping that it willhelp me when I write tests, perhaps with Mocha.

Runninga free-to-play game presents a unique opportunity to get my hands dirty, as Iget a ludicrous number of data points very early in my business – the kind ofdata that with a SaaS business you would only get at significant scale. Since then, traffic to Solitr has risen to 4000 daily visits (mostly throughranking for niche keywords), even though I haven’t been able to work much onit so far. Some testing with AdSense indicates that I can start paying therent with it. It also makes meconfident that once the search ranking improves, I can have a viable business.

Probably the most important feature in Ember is attribute binding. Itallows attribute changes to automatically propagate through all layers of yourapplication. I would like to thank Richard Hoelscher, who created an excellent vector version of Grimaud’s 19th-century “Paris pattern” card deck (see the archived page or download paris.svg).

Hackathon Retrospective

Also, Ipicked up a lot of CoffeeScript and jQuery that I wouldn’t have beenexposed to otherwise. The past four months have been dedicated to working full time onBroccoli (blogpost), thanks tosome savings from my previous consulting gigs, combined with moderate livingexpenses. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.

• In retrospect, taking time off to write Broccoli was clearly worth it.
• Probably the most important feature in Ember is attribute binding.
• I hope to pay itforward by being open about Solitr and blogging about my adventures with A/Btesting in a similar vein.

Changes To This Privacy Policy

While the model implements rule logic (with methods like foundationAccepts),it does not enforce it. The controller has to check whether a given action islegal in order to give proper user feedback. It then seemed redundant toimplement another such check in the game state model. The application essentially consists of two files,models.js.coffeeandcontrollers.js.coffee(written in CoffeeScript). In this situation, compromising on the quality of the animations is ano-brainer for a regular web application. Since they are so ubiquitous in a game (even asimple one like solitaire), treating them as less than first-class citizen willyield hundreds of lines of unmaintainable animation spaghetti code.

Cards on the tableau need to be stacked by alternating color from high rank (King) to low rank (Ace). Empty spots on the tableau can be filled with a King of any suit. The goal is to move all cards to the four foundations on the upper right. There are many coordinate properties on the event object, but you should usee.pageX and e.pageY, which arestandardizedby jQuery to return the coordinates relative to the top left corner of theentire document. I’ll definitely do hackathons again.Being able to whip up a webapp on a whim is such a good feeling.

When thirteen cards of the same suit from King all the way to Ace are together on a tableau column, they are automatically moved to the foundations. (Incidentally, Draggable derives from this.) We can use thisto handle mouseStart, mouseDrag, and mouseStop events in a way that worksconsistently across browsers. But simply binding to mousedown and mousemove events yourself will cause aheadache because you’d have to work around subtle cross-browser compatibilityissues.

Event Sequence

However, for game code, I have found that this pattern works very well, and ithas turned out to be very maintainable so far. My role model for this is Patrick McKenzie– my Solitr is approximately equivalent to his Bingo Card Creator – and hisextensive blogging has been of immeasurable value to me. I hope to pay itforward by being open about Solitr and blogging about my adventures with A/Btesting in a similar vein. In retrospect, taking time off to write Broccoli was clearly worth it. I wentone month over my original budget of three months, but people’s enthusiasticreactions at EmberConf have convinced me that I solved a worthwhile problem,and that writing Broccoli will pay off in productivity increases across thecommunity. Personally, having Broccoli will help me with the upcoming work onmy business, and writing it has helped me become a better developer.

In which I show how to harness jQuery UI’s Mouse plugin to roll your owndrag-and-drop handling, when Draggable is not flexible enough for you. I haven’t found it necessary to derive either models or controllers from acommon base class. I’ve found that by doing a hackathon, I’m forced to just keep working,so I’m producing code all day. I’ve rarely gotten so much output from mybrain in one day.

If I start a business in the future (say a B2B SaaS)and it gets traction, I’m hoping that data-driven tools like A/B testing willallow me to scale it and realize returns much faster than I’d be able tootherwise. I also want to learn A/B testing, in parallel to the SEO work. A/B testingrequires many data points to yield statistically significant results.
