The Dota 2 Workshop update is even more interesting than it first appears. The new tools include an overhauled edition of Valve's Hammer level editor, and the update download adds a 64-bit build of Dota 2. Both contain allusions to the next generation of Valve's Source engine. Set the Half-Life 3 alert to DEFCON beige.
Technically-minded modders and map-making enthusiasts are busily dissecting the tools in detail, but it's immediately clear that Hammer has been greatly improved. The interface has been overhauled, and the editor now renders the level in real-time as you tweak level geometry. It also runs on a new file structure. When you open a file in the editor, you can now choose to open a new "vmap" file, or an old fashioned "Source 1.0 Map File". The community is still puzzling over the advantages offered by the new directory system, but it looks like Valve are laying important groundwork for future releases.
It's interesting to note how user-friendly the new tools are. Dota Redditors are already having fun with functions that let you sketch out levels quickly (via DarkMio ) using tilesets. As well as Dota 2's traditional forest set, there's the wintry Frostivus set and this one . Valve have a history of encouraging user-created content, including campaigns and levels. Hammer's complexity surely stunted the potential of Left 4 Dead's ecosystem—a problem Valve tried to circumvent with Portal 2's lovely level-creation tools. Nu-Hammer could serve as a friendlier entry point for tinkerers.
In addition to all that, the latest Dota 2 update also adds a 64-bit version of the Dota 2 client, which you'll find tucked away in steamapps/common/dota 2 beta/dota_ugc/game/bin/win64. It contains numerous references to second-gen elements, like "engine2.dll", "materialssystem2.dll" and "vphysics2.dll", and comes with a colourful new console. It's a bit premature to say that Dota 2 has been ported to Source 2 wholesale, we're likely looking at an interim step as Valve roll out tools designed to support their current games and future projects.
This is quite exciting nonetheless. Publicly Valve have been laser-focused on Dota 2, but are of course rumoured to be working on Left 4 Dead 3 and, what was it again, Hearth-Life? Bath-Life? As someone who likes Valve games, but can't quite get into Dotes, I wait in meditative stasis for a new Valve happening , be it an announcement or an ARG. Our time will come.
