A couple of years back I and Jim Munroe released an alpha version of Texture, a touchscreen optimized interactive fiction authoring system in which you drag and drop words on top of story text. We've worked on the release version ever since and earlier this week it was published at texturewriter.com.

There are too many new features to list them all, but here are the highlights:

• New layout, user interface and typography. Page text adapts to available screen space automatically.
• State tracking through flags and behaviors: actions can toggle flags on and off, which in turn lets the author trigger alternative behavior based on which flags have been set.
• The action's name (which is displayed when the command is dragged over its target) doesn't have to be strictly verb-noun anymore. The most common use case is adding prepositions ("sit under tree" instead of "sit tree") but it can be changed to anything at all ("sit" + "tree" → "rest under the redwood").
• Command targets can consist of more than one word by using underscores which are shown as spaces in the final story (e.g. "oak_tree" would be printed as "oak tree" but both words would be targeted at the same time.)
• A command target can be reused after an action has replaced it with new text by enclosing a word in the new text in [brackets].
• Basic text formatting options (bold and italic text).
• Cover page and cover art; the cover page also acts as a tutorial for people who are playing a Texture game for the first time. Clicking or tapping the play button shows a "ghost" of the button being dragged to demonstrate how interaction works, and clicking again pops up explicit instructions.
• Preview right in the editor, with a debugging console for manually toggling flags and following internal behaviors and flag changes.
• Exporting and importing project backups.
• An interactive tutorial that guides you through the basic features.

In addition to new editor features, stories can be published online at texturewriter.com without needing to download the project and host it on your own web site.

Logging in to the web site will automatically save your projects to the server, so they'll be safe even if you clear the browser's cache and you can access them on any device by logging in. You can still use the system as a guest, in which case the projects will be saved locally to the browser (and nothing is sent to the server), but then you'll have to back up the projects manually.

The flag system makes Texture a "real" system with state tracking instead of just simple tree-like branching. In terms of story logic we're unlikely to add features to the online IDE because it's starting to approach the limit where the visual interface can't represent more complexity in a way that wouldn't make writing stories cumbersome and error-prone. We're planning to release the Texture Reader (analogous to parser game interpreters) as a JavaScript library which would allow writing story logic of any complexity using JavaScript.

Other new features are possible though, and the next major feature under development is story-specific layout options (color and font choice.)
