Unity Traffic System – City Traffic

Andy — Mon, 13 May 2013 12:05:01 +0000

Creating a sandbox style traffic system in Unity is a challenge. As our previous posts have shown agents can use NavMesh and calculate shortest paths but the hit is high on processing which in turn limits the number of agents in a scene. Sander van der Vegte is a multidisciplinary game developer who for the past 12 years has fortunate enough to make a living creating games, part of his current development process is a city traffic game and thus finding ways for natural behaviour while maintaining a low processing requirment.

Unity City Traffic

The clip below is a recording of an autonomous traffic system. Cars drive around while aware of crossings and other vehicles. When something is blocking their path, they will stop. If it takes too long, they will back up and look for another path, the basic ruleset allows for humorous situations:

Within the development the user is able to click on a car to take it over while falling off the edge triggers the random camera again.
It is well worth heading over to http://sandervandervegte.nl/ to view his other projects and to keep up to date on City Traffic.

Frank Lloyd Wright: Fallingwater in Half Life and CAD

As Half Life is finally available on the Mac, thanks to Steam, we thought it was time to repost two of our favorite movies – detailing Falling Water playable in Half Life and rendered via CAD.
Fallingwater, also known as the Edgar J. Kaufmann Sr. Residence, is a house designed by American architect Frank Lloyd Wright in 1935 in rural southwestern Pennsylvania, 50 miles southeast of Pittsburgh, and is part of the Pittsburgh Metro Area. The house was built partly over a waterfall in Bear Run at Rural Route 1 in the Mill Run section of Stewart Township, Fayette County, Pennsylvania, in the Laurel Highlands of the Allegheny Mountains (Wikipedia)
The movie above by etereaestudios.com represents one of the best visualisations of Fallingwater we have seen:

Using the Source Engine, as opposed to more traditional Architectural Software, allows the use of dynamic lighting and a real-time walkthrough of the scene in high resolution:

Crysis: Physics Engine Movies

Crysis LEGO map from Robert Tieber on Vimeo.
The Crysis engine has an inbuilt physics system that supports vehicles, rigid bodies, liquid, rag doll, cloth and soft body effects. The movies in this post provide a glimpse of the physics engine in action, the first clip above demonstrates the ‘Lego’ modification running in real-time.
The following movies illustrate the use of the physics engine of Crysis in maximum effect. Note each one was rendered frame by frame using the ‘linked method’, take a look at this thread for full details.

Readers may recall our work earlier work in Crysis, a change of deadlines stalled the earlier work somewhat but we will be returning to Crysis in terms of physics, agents and urban modelling in the coming months…
