  Phaser 2 and our plans for the future

  29th Mar 2014

  Exactly 6 months after the release of Phaser 1.0 we released version 2. It was a huge update. Not so much in terms of new features, although it did bring its fair share of tasty new treats to the table. But more so it underwent a large internal change. We upgraded to the latest version of Pixi.js, our renderer and this in turn allowed us to literally shave thousands of lines of code out.

  The core update loops of all the game objects like Sprite and Button, were dramatically reduced. Lots of the things that caused Phaser 1.x to not be quite as optimal as it could be were eliminated. Expensive routines and processes were either removed entirely or disabled where possible.

  It was a big update, but it felt good. It felt clean and fresh. Like when you tidy-up your work space, or white wash a room ready for painting. You know you’re building on top of something sound.

  There were a number of API breaking changes moving from v1 to v2, which is why we jumped version number so high (originally it was just going to be the 1.2 release). It was a lot of simple but important alterations. Things like the Group class now properly extending a DisplayObjectContainer, so they can easily be nested and shifted around the display list. Or Sprites no longer having physics bodies by default, or input handlers, which meant the amount of code they process during their basic update is now utterly minimal. Those features are still available of course, you just have to activate them explicitly. The changes were so extensive we produced a Migration Guide to help developers shift over.

  The TriForce

  Traditionally Phaser has had the ArcadePhysics system built in. This was a port of the one found in Flixel and our Flixel Power Tools. It was fundamentally basic, but still covered quite a lot of bases and most importantly was very easy to use. However the limitations really started to bug us, and we tried to address them in the 1.1.4 release of Phaser, with less than stellar results.

  A strong reason for us developing Phaser 2 was so that we could use a proper full-body physics system, in our case the excellent p2.js by Stefan Hedman. And for a good while this was the only physics system we had built in. But as we worked through the weeks of development, it became apparent that there was a real need to keep ArcadePhysics around. Not the broken 1.1.4 version, but the earlier release that mostly just worked, because it didn’t try to be too clever.
