Unity Technologies今日宣布全新的Unity 4.0游戏开发工具已可供用户购买使用，而在之前的6月份该公司曾表示将为Unity 4.0添加更多的新技术和新功能支持。

据介绍，新引擎不但加入了DriectX 11支持和Mecanim动画工具，而且还增添了Linux和Adobe Flash Player部署预览功能，这些改进将更有助于开发者制作出高品质的游戏作品。

对于Unity 4.0的正式发售，Unity Technologies的CEO David Helgason表示：“这是一个令人激动的时刻，Unity 4.0标志着一个伟大新时代的开始，它不但具有数项全新技术和功能，而且还会得到公司持续不断的后续技术支持，而这些都是在Unity历史上绝无仅有的。”

其中，免费版Unity 4.0的用户只能选择购买Adobe Flash Player、iOS、Android以及Team License（团队许可）四种扩展功能包，其价格从400美元到500美元不等。

对于那些购买Unity Pro产品的用户来说，他们的选择面会更大一点，除了上面四款扩展功能包之外，还可以选择售价均为1500美元的Adobe Flash Player Pro、iOS Pro以及Android Pro三种更高等级的扩展功能包。

Unity Technologies, provider of the Unity multi-platform engine and development tools, is proud to announce Unity 4.0 is now available. Unity 4 will consist of a series of updates designed to improve the product through an extensive improvement of existing tech and the rollout of new features.

The first in a series of updates for Unity 4, this version includes significant additions such as DirectX 11 support and Mecanim animation tools. In addition users will have access to a Linux deployment preview and the Adobe Flash Player deployment add-on.

Mecanim – Stunning Character Animation

Mecanim, Unity’s powerful and innovative animation technology, is setting new industry standards for tools in integrated development environments allowing the creation of complex state machines, blend trees, IK rigging, and auto retarget animations to characters of different sizes and shapes, all inside of the Unity editor.

DirectX 11

With the ability to take advantage of full DirectX 11 support, including shader model 5, tessellation for smoother models and environments in game worlds, and compute shaders for advanced GPU computation, Unity 4.0 empowers developers.

High-end Visual Capabilities for All Platforms

Unity 4.0 also features real-time shadows on mobile, skinned mesh instancing, the ability to use normal maps when baking lightmaps, and a refined GPU profiler. It’s easy to make extremely high-end visuals that scale across the best of what’s available on modern PCs and the most advanced mobile graphics chips.

Adobe Flash Player Add-on

The Adobe Flash Player deployment add-on will empower developers to publish their new and existing titles to one of the world’s most ubiquitous gaming platforms on the web. With the wealth of incredible features in the 4.0 release, Unity is the most powerful development pipeline for creating high quality 2D and 3D content for Adobe Flash Player.

Unity 4 introduces many additional features and improvements, including:

- Shuriken particle system supports external forces, bent normals, automatic culling, and environmental collisions

- 3D texture support

- Navigation: dynamic obstacles and avoidance priority
