Terrain Reasoning for 3D Action Games
There's an in depth tutorial over on Gamasutra which tackles terrain reasoning. This is the capability of the A.I. to best use the waypoint data. The article is thorough, and interesting to read. Beware of the huge images though! One PNG is over 640kb, so those of you with modems will have a bit of fun... makes you wonder why the site is wasting valuable bandwidth like that! Anyway, back to the technical details. The one thing that bothers me about this approach is the waypoints: they are disposed on a grid, at fairly close interval. Albeit the simplicity of this method, it implies that a fair bit of redundant data is stored. A significant part of the paper describes equations used to make sense of this data for the A.I. A simpler set of waypoints would require less complexity to interpret. More on that very soon, I promise! |
