Posted by: eddaket April 1 2006, 10:23 pm Come back soon as new guides and SA goodies will be added all the time. Vehicles cannot plan accordingly, for example, if there is any type of road blockage."īut this new system will allow the NPCs to react to situations in real-time and plan new routes if their current one is blocked.Welcome to the Grand Theft Auto: San Andreas section, a brand new section that will cover San Andreas in as much detail as possible. This can result in very late detection of potential issues and no high level knowledge of `this road is blocked ` instead, the system only indicates that there's something in my way to be avoided.
This is done every frame for each entity and no knowledge of the previous frame is used. This involves, each frame, checking the local environment for any potential obstructions (vehicles, pedestrians, objects), building up a view of that obstruction from the local vehicle (creating a `front facing` polygon which is a list of points/lines that the vehicle will need to avoid in order to not hit the obstruction), generating information about the road the vehicle is on so they can avoid going off-road into buildings and finally generating and detecting the best steering angle to avoid all the obstructions.
This is explained in the patent, with it stating that, "As an additional drawback, conventional systems relied almost entirely on local traffic avoidance for NPCs to avoid collisions. The patent describes a new system that will allow NPCs to act intelligently and react to situations and hazards in real-time. Rockstars Games has applied to patent a new technology called "System and Method for Virtual Navigation in a Gaming Environment".
