Unity Pro 2019.2.2f1 – AI/VR游戏开发软件

Unity3D是由Unity Technologies开发的一个让玩家轻松创建诸如三维视频游戏、建筑可视化、实时三维动画等类型互动内容的多平台的综合型游戏开发工具，是一个全面整合的专业游戏引擎。

特点：

其他改进包括艺术家的新工具，如运行时动画绑定和音频，视频和DCC工具的更改。时间轴现在是一个经过验证的包，其中包含一个新的信号功能，允许时间轴与场景对象进行交互。

对移动发布的更改包括修补应用程序包而不是执行完全重建的功能，新的移动自适应性能功能可提供有关热趋势的数据等。

Linux用户将很高兴在这里可以预览兼容版本的Unity Editor。

性能改进包括继续研究多线程面向数据的技术堆栈，可以在创建Megacity演示的过程中看到。同时还宣布了与Havok合作开发的新物理解决方案。

Fixes

• macOS: Fixes an issue with macOS Catalina that causes Unity to request permission to receive keyboard input when using other apps in both the editor and standalone player. (1172758)
