Unity game engine embraces Google's Native Client
The cross-platform game software now reaches Google's software for faster Web apps and previews support for Flash. Also: new features and better performance.
Startup Unity Technologies released version 3.5 of its video game engine that now includes support forbrowser-boosting software.
Unity's software is a cross-platform tool that lets game programmers reach a wide range of devices--everything from iPhones to Windows to browsers. Cross-platform tools are only worth it if they reach a broad number of platforms, though, so it's important to expand, and the company has been.
Native Client is Google software built into Chrome that lets programmers run lightly modified C or C++ software directly in the browser. Ordinarily running such native software, compiled by programmers and downloaded over the Internet, would be a security nightmare. But Native Client, aka NaCl, comes with security protections--it only lets permitted instructions run, and it executes software in a protective sandbox.
NaCl got its start on x86 processors from Intel and AMD, but Google has been working to adapt Native Client for ARM-based systems. However, Google doesn't support NaCl in its new, which runs on ARM-based mobile phones.
Unity 3.5 also has a "preview release" of support for Adobe Systems' Flash Player 11 plug-in, whose most notable difference over predecessors is support for the Stage 3D interface for hardware-accelerated 3D graphics. Flash is widely installed on personal computers, but Adobe abandoned an effort to bring it to mobile devices.
In addition to the new platform support, Unity 3.5 includes a number of new programming features, too. Among them:
The Shuriken system for particle-based visual effects to simulate things like fire and smoke
Better and faster lighting effects such as high dynamic range imagery
Smarter "pathfinding" algorithms for directing characters around obstacles or through crowds
Better performance through improved "occlusion culling," which means a computer doesn't have to waste as many resources handling objects that can't be seen
An interface for social gaming
The upgrade is free for Unity 3 developers. The software comes in a free basic version or costs $1,500 per developer for Unity Pro.
