Abstract
The invention provides a path fining method for a game role. The path fining method comprises the following steps: S1, receiving a path fining command, wherein the path fining command comprises an initial point and a target point; S2, according to the path finding command, searching for a first direct path from the initial point to the target point in a current map, meanwhile, searching for a second direct path from the target point to the initial point, and dividing the current map into gridding path finding points, wherein the initial point and the target point belong to the path finding points; S3, stopping the search when an overlapping path finding point appears between the first direct path and the second direct path; S4, judging whether a barrier point exists in the path finding point between the first direct path and the second direct path; S5, if yes, optimizing the first direct path and the second direct path to remove the barrier point; S6, connecting the first direct path and the second direct path to serve as the shortest path finding path. By means of the method, the searching time for path finding can be shortened.
Description
Technical field
The present invention relates to technical field of network information, particularly relate to a kind of method for searching of game role.
Background technology
When game user is played games, need direct game role to perform various action, comprise movement, fight etc.And movement is the elemental motion of game.In order to make game user spended time and energy go to find the target in game, automatic pathfinding is arisen at the historic moment, the target location that automatic pathfinding can make game role be automatically moved to game user to specify.
Traditional automatic seeking path method is all map is divided into latticed pathfinding point, after game user selected target point, searches for the shortest reachable path from starting point to impact point.This mode can find shortest path very soon when impact point is shorter apart from starting point, but when impact point distance starting point is larger, then require a great deal of time removal search, thus add the search time of pathfinding.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of method for searching of game role, can reduce the search time of pathfinding.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the method for searching providing a kind of game role, and described method for searching comprises: S1, and receive pathfinding instruction, pathfinding instruction comprises starting point and impact point; S2, searches for first direct path from starting point to impact point according to pathfinding instruction in current map, and search for the second direct path from impact point to starting point, current map is divided into the pathfinding point of gridding, and starting point and impact point belong to pathfinding point simultaneously; S3, stops search when overlapping pathfinding point appears in the first direct path and the second direct path; S4, judges in the first direct path and the second direct path, whether pathfinding point exists obstacle object point; S5, if so, is optimized the first direct path and the second direct path, to remove obstacle object point; S6, is connected the first direct path as the shortest pathfinding path with the second direct path.
Preferably, before step S1, method for searching also comprises: when game user generates pathfinding instruction during selected target point on current map, and starting point is the current residing pathfinding point of game role that game user is handled.
The invention has the beneficial effects as follows: the situation being different from prior art, the method for searching of game role of the present invention is by searching for direct path to the other side from starting point and impact point simultaneously, and search data amount significantly reduces, thus can reduce the search time of pathfinding.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the method for searching embodiment of game role of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the schematic diagram of the method for searching embodiment of game role of the present invention.The method for searching of the embodiment of the present invention comprises the following steps:
S1: receive pathfinding instruction, pathfinding instruction comprises starting point and impact point.
Wherein, pathfinding instruction is triggered by game user.Specifically, in the present embodiment, before step S1, method for searching also comprises: when game user generates pathfinding instruction during selected target point on current map, and starting point is the current residing pathfinding point of game role that game user is handled.
S2: search for the first direct path from starting point to impact point according to pathfinding instruction in current map, search for the second direct path from impact point to starting point, current map is divided into the pathfinding point of gridding, and starting point and impact point belong to pathfinding point simultaneously.
Wherein, map partitioning is the pathfinding point of gridding, and a pathfinding point is a grid, and all map scenes comprise ground, forest etc. and are filled in pathfinding point.
The mode of search direct path can be realized by A star algorithm, and A star algorithm belongs to the common practise of those of ordinary skill in the art, repeats no more herein.In search first direct path and the second direct path process, the pathfinding point traveled through is the half or following of the pathfinding point traveled through from starting point to impact point unidirectional search, thus significantly can reduce the data volume of search.
S3: stop search when the pathfinding point overlapped appears in the first direct path and the second direct path.
Wherein, the first direct path and the second direct path occur that the pathfinding point overlapped shows that the first direct path and the second direct path are connected mutually, thus the path that formation one is complete.
S4: judge in the first direct path and the second direct path, whether pathfinding point exists obstacle object point.
Wherein, obstacle object point can for having the pathfinding point of special marking, by inquiring about in the first direct path and the second direct path whether comprise the judgement that special marking realizes obstacle object point.
S5: if be optimized the first direct path and the second direct path, to remove obstacle object point.
Wherein, the mode of optimization can be the new pathfinding point of non-obstacle object point as the first direct path and the new pathfinding point of the second direct path of selecting obstacle object point to adjoin.
S6: the first direct path is connected as the shortest pathfinding path with the second direct path.
Wherein, after the shortest pathfinding path is determined, game role will start mobile according to the shortest pathfinding path, until arrive impact point.
By the way, the method for searching of game role of the present invention carries out bidirectional research in starting point and impact point simultaneously, and the pathfinding point traveled through in search procedure significantly reduces, thus can reduce the search time of pathfinding, and by being optimized two direct paths, realize optimum path.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
