Abstract

The invention provides a path-finding navigation method and device capable of dynamic modification for a super-large map, and relates to the field of mobile communication terminal game application. Atriangular navigation sequence between a starting point of a target object and a target triangle is established; rasterization is conducted on the triangular navigation sequence, and quadtree cuttingis conducted to form nodes of a quadtree structure; a navigation node sequence in the nodes of the quadtree structure is determined based on the starting point and the target triangle; the target object is controlled to move based on the navigation node sequence, so that the problem of overlarge data volume generated by way-finding navigation in a super-large map is solved. By rasterizing the projection of the dynamic obstacle, setting the new node of the quadtree structure and re-determining the navigation node sequence, the beneficial effects of reducing the memory occupation space and dynamically modifying the navigation during running are achieved, so that the game operation is more convenient, and the experience is more real.

Description

technical field [0001] The invention relates to the application field of mobile communication terminal games, in particular to a dynamically modifiable pathfinding and navigation method and device for super-large maps. Background technique [0002] In a 3D massively multiplayer online role-playing game (MassiveMultiplayer Online Role-PlayingGame, MMORPG), it is often necessary to generate a pathfinding navigation for the world, so that non-player characters (Non-Player Character, NPC) can find their way and move to a specific location . Usually the game will generate navigation data offline, and when the game is running, use specific algorithms to quickly find the way. [0003] The currently commonly used navigation generation tool is RecastNavigation, which is an existing navigation generation tool. It uses a set of adjacent convex polygons to describe a 3D scene, and can import physical models to generate navigation. The pathfinding node generated by RecastNavigation is ...
