Unreal Engine 3 is a complete game development framework for next-generation consoles and DirectX9-equipped PCs, providing the vast array of core technologies, content creation tools, and support infrastructure required by top game developers.
UDK ’s artificial intelligence system provides two robust systems for AI navigation. UDK supports the automatic creation and use of navigation meshes, giving AI-controlled characters increased spatial awareness of their environment and the ability to make smarter movement decisions.
The UDK Navigation mesh implementation optimizes the performance and memory usage of AI in many scenarios relative to traditional node-based navigation systems, thanks to a more efficient representation and less reliance on collision-detection for movement. UDK also provides an up-to-date implementation of the robust and well-tested node-based navigation system used in Unreal Engine games over the last 12 years.
