During this year’s Hack Week, ROBLOX developers shifted gears, working tirelessly to devise and present ideas fueled more by creativity than priority. This week, we’ll be featuring some of the most innovative ideas to come out of Hack Week. Our first story is about a “Crafting” system in ROBLOX, by Software Engineer Navin Lal.

The idea of “Crafting” has been in the gaming world for a long time; DotA, Ultima, Everquest, and even Diablo have featured their own versions of the concept. It’s an undeniably interesting idea that is worth exploring in the world of ROBLOX. In order to better explain our unique take on a crafting system, let’s split the notion into two categories: materials and recipes. We’ll go over materials first.

Tim Brown’s Hack Week project would give ROBLOX developers a powerful tool for engaging players. 

ROBLOX is about user-created content, and our users have created a lot of content — so much that you’d be hard-pressed to experience all of it in a lifetime. ROBLOX players need to be able to get to the good stuff, fast.

My hack week project was to explore rendering styles and visual effects that would take ROBLOX to the next level. The ROBLOX rendering engine works in a difficult environment compared to traditional games –

• ROBLOX places are made by our users
  (rather than by hired-on level designers)
  Usually game companies can control their content. They can impose a strict set of rules about how many polygons are used, how to place particular items, and how much of a level is static. ROBLOX is different – builders can come up with anything, with no restrictions and no budgets.
• ROBLOX places are very dynamic
  In ROBLOX, any part is physically simulated by default – so it could move or change every frame. Even anchored parts could be changed at any point in time through scripting (they often do). Terrain is a great example – although it’s always anchored and cannot move, scripts and tools change it all time.
• ROBLOX runs on wide range of machines
  ROBLOX works on 10 year old computers with a 32MB video card, as well as on the latest monsters with gigabytes of memory. Any rendering effects we use must gracefully scale down and up immensely.

Whenever we think about improving the look and rendering effects on ROBLOX we need to keep all of this in mind.

Hack Week coverage continues with a unified tech demo by Dan Ignatoff, Erik Cassel and Tim Loduha showing water, buoyancy and ropes working together.

This is a first look at the ROBLOX code stack running on an iPad. Product specs are in development and there is no announced ship date. The tap-to-move interface shown in the demo is a place holder for future thumb controls. Textures and skyboxes are disabled.

We are building off the same code as our PC and Mac clients. Rendering speed is surprisingly good. Features, bug-fixes and enhancements for the PC/Macintosh ROBLOX will show up on the iPad. Over 95% of our code base is common among all platforms, including networking, rendering, physics, sound, core, threading and lua execution.  The demo is running in full client-server mode with networking.  We can join ROBLOX servers with the iPad demo over WiFi.

While many were enjoying chestnuts roasting on an open fire (well, not here in the Bay Area, thanks to the nightly Spare the Air alerts), our dev team took advantage of the Holiday break by participating in our first-ever Hack Week.

What’s Hack Week, you ask?

How will our users create bigger and better games? Navin Lal’s Hack Week project presents his vision of the future. 

Universes would allow ROBLOXians to create massive game spaces by linking multiple games together. You would not only travel to and fro (thanks to the ever-handy means of teleportation), but all of your ROBLOXian character’s previous accomplishments within the “Universe” — whether it’s experience, currency, progress, events and more!— would accompany them too.
