AI & Navigation

Creating interesting and useful AI relies on those entities being able to intelligently and realistically navigate the world. Traditionally, Unreal Engine has relied on a waypoint-based system which was used to create a path network. With the addition of the navigation mesh-based system, the world can be represented in a much more efficient and accurate manner. This means navigation has become much more efficient in terms of memory needed to store the data structures and is able to produce much more realistic movement. This section contains documentation over moving AI-Controlled entities from one location to another using one of the navigation systems, Waypoints or Navigation Mesh, provided in Unreal Engine 3.
