GDC 2014

I was fortunate to be able to attend the Game Developers Conference in San Francisco this year. Thanks to our organizers and IT staff for all the hard work they put into making everything run so smoothly.

This was the first year Mozilla had an actual booth on the show floor and we put it to good use demoing our Developer Tools alongside some fun games. We showed off our new Canvas Debugger (should be landing next week!), the Shader Editor as well as our Debugger and our other inspection tools. People were really receptive to the Canvas tool. The Shader Editor got a fair number of positive comments as well. I was also able to show off our Network panel as a temporary solution for inspecting game assets like textures.

Another well-received demo was a setup where I paused my desktop JS Debugger when receiving a device orientation event on my phone. I loaded the three.js DeviceOrientation demo on my phone’s browser (Firefox for Android). I then connected the phone via USB to my laptop and launched our remote tools via the “connect” option. Opening the Events panel, I was able to pick “deviceorientation” as a category and selecting that caused execution on the phone to immediately pause with my desktop debugger showing the exact location.

Debugging device events is easy to do on a mobile device. I was also able to demo our Shader Editor running on mobile which was pretty cool. Editing shaders in real-time running on a remote device is some real science fiction level stuff.

Having the kind of immediate feedback for WebGL (and soon WebAudio) that our tools provide is kind of a big deal for people who aren’t used to living in a dynamic environment like a web browser. There is lots of opportunity in this space to make tools for game developers that are fun to use and interactive. You can literally program your game while playing it.

This feels like a tipping point for games on the web. There are now multiple engine developers offering the Web as a bona fide deployment target. Three big engines have reduced their pricing models to the point of being effectively free for most developers and that happened just this week. This is a big deal and I think we’re going to start seeing a lot of game publishers shipping games to the web very soon.

We also weren’t the only booth showing off HTML5-related game technology. Nintendo is shipping a “Web Framework” around a bundled WebKit shell for deployment on the WiiU and had a pretty sizeable installation to show it off. Unity is also making that a deployment target. Various other booths were demoing HTML5 games and tech.

In the emerging technology department, head-mounted displays were in full-evidence. Sony just announced a new piece of head-gear for the PS4 and there were some other vendors kicking around similar technologies. At this point, it seems obvious that head-displays are going to be very real, very soon. The lines of people at Oculus’ displays were a constant stream of humanity.

Updated Console Keyboard Shortcuts in Firefox

Keyboard

keyboard” by Mark Lane on Flickr

Cmd-Alt-K on OS X or Ctrl-Shift-K on Linux or Windows will now always focus the console input line. It will no longer close the entire toolbox and you’ll have to use one of the other global toolbox commands, Cmd-Alt-i (or Ctrl-Shift-i) or F12.

Keyboard shortcuts.

They are the bane of Firefox Developer Tools engineers. Ask us in #devtools for a new keyboard shortcut to do X and you will be greeted by a chorus of groans. There just aren’t enough keys on a keyboard for everything we need to use them for.

I added a recent change to automatically focus the Console’s input line when clicking anywhere in the console’s output area (bug 960695). This spawned a series of follow-ups.

The first of these was the addition of Page Up and Page Down controls on the input line. (bug 962531). Now when the input line is focused, it will scroll the output area with page up and page down keys. If the autocomplete popup is active, it’ll scroll too. It’s a little thing that’s nice to have when you’re flipping through all of the completions for, say, the global window object.

The most important change we landed this weekend is a change to the Console’s main Keyboard Shortcut, Cmd-Alt-K on OS X or Ctrl-Shift-K if you’re on Linux or Windows. This key will now always focus the console input line. It will no longer close the entire toolbox and you’ll have to use one of the other global toolbox commands, Cmd-Alt-i (or Ctrl-Shift-I) or F12. (see bug 612253 for details and history)

Try it out. Tell us if you hate it. You can reach us here, IRC, or on the twitters.

And there’s still more to do. I filed bug 967044 to make the Home and End keys do the right thing in the Console’s input line. We have this “metabug” tracking all of the open shortcut bugs in Firefox Devtools. Are we missing any? Let us know!

New DevTools Peers, October 2013 Edition

rabbid

This week, we are proud to add Brandon Benvie, Brian Grinstead, Patrick Brosset and J. Ryan Stinnett as peers of the Developer Tools Module.

Brandon Benvie of es-discuss fame has been tackling difficult problems such as remoting our Scratchpad and making things use protocols they were never designed to use. In addition to that, he knows a thing or two about generators and promises that just might scare your hair white. He can review Scratchpad and Variable View patches and is pretty capable with Debug Protocol stuff. And Promises.

Brian Grinstead, recently-famous for his excellent Edit as HTML feature in the Inspector is working on the Devtools Content Team. He has been described as being “very thorough” so you should send him reviews for the Inspector, Style Inspector and anything else you want reviewed. Thoroughly.

Patrick Brosset completed the recently-added doorhangers on colors and image previews in the inspector. Little did he realize he would have to contend with the mysteries of the XUL Panel element when he set out on this noble path. He is also the creator of this neat thing. You should probably send him some Inspector and Style Inspector reviews. Also, feel free to ask him how he feels about mustard.

J. Ryan Stinnett (or jryans as he is called in IRC) has been busily adding support for the Manifest Editor in the App Manager. For a second trick, he’s been working on adding support so our JS Debugger can finally debug itself. Yo dawg. You should send him requests to review your App Manager patches.

Congratulations and happy code reviewing!

New Devtools Peers: Jim Blandy and Alex Poirot

Please be advised, we have two new peers in the Firefox Developer Tools Module:

Jim Blandy, our Remote Protocol author, has been added as a reviewer for the Debugger.

Alex Poirot (aka “ochameau” on IRC) has been working with Paul on a new App Manager component for debugging apps on B2G. It should be landing soon.

For code reviews,

  • Mihai Sucan, (Console, Net Monitor, Source Editor)
  • Joe Walker, (GCLI, Inspector, Framework)
  • Paul Rouget, (Framework, Inspector, Responsive Mode, App Manager)
  • Panagiotis Astithas, (Debugger, Scratchpad)
  • Heather Arthur, (Inspector, Scratchpad, Style Editor)
  • Mike Ratcliffe, (Framework, Inspector)
  • Victor Porof, (Debugger, Net Monitor, Tilt)
  • Anton Kovalyov, (Profiler, Scratchpad, Source Editor)
  • Nick Fitzgerald, (Source Maps, Debugger)
  • Jim Blandy, (Debugger, Remote Protocol)
  • Alex Poirot, (App Manager)
  • Rob Campbell (Scratchpad, Debugger, Profiler, General)
  • Dave Camp (Debugger, Inspector, Framework, General)

Also, Dave would like to keep an eye on changes to directory structure and the loading of our Tools while we transition to a new top-level /devtools directory. We ask that changes to devtools/Loader.jsm should go to him.

Please be kind to our Developer Tools Peers. Send them lots of patches.
