US 6,319,129 B1 · Method and a video game system of generating a field map

Abstract

A method and a video game system that are capable of generating a field map with more natural geographical feature. The method and the video game system firstly divides the field map including a plurality of blocks into a first zone and a second zone by a boundary which consists of sides and comers in the blocks, then determines a first point for each side included in the boundary and a second point for each corner included in the boundary. Finally, the boundary is transformed into a more complex land shape by connecting the first points and the second points. The video game system includes a block division unit that divides the field map into a plurality of blocks, a block assign unit that assigns each of the divided blocks to either a first zone or a second zone using a boundary that consists of sides and comers of the blocks, a first point determining unit that determines a first point for each side, a second point determining unit that determines a second point for each corner, and a transforming unit that transforms the boundary by connecting the first points and the second points.

A method of generating a field map used in a video game, comprising the steps of:

dividing the field map which consists of a plurality of blocks, into a first zone and a second zone by a boundary including sides and corners of the blocks;
determining a first point for each side of the boundary on the basis of a location of each side of the boundary;
determining a second point for each corner of the boundary on the basis of a location of each corner of the boundary;
and
transforming the boundary by connecting the first points and the second points.

A video game system which generates a field map comprising:

block division means which divides the field map into a plurality of quadrilateral blocks including a plurality of quadrilateral cells;
block assign means which assigns each of the divided blocks to either a first zone or a second zone;
side select means which selects sides each of which forms a part of a boundary between the first zone and the second zone, from sides of the blocks;
corner select means which selects a point which corresponds to a corner of one of the blocks and which is included in the boundary;
first point determining means which determines a first point for each selected side on the basis of a location of each side of the boundary;
second point determining means which determines a second point for each selected point on the basis of a location of each corner of the boundary;
first point selecting means which selects two first points each of which corresponds to a side, the two corresponding sides are adjacent to each other;
second point selecting means which selects one second point which corresponds to a corner formed by the two corresponding sides
third point determining means which determines a third point by moving the selected second point on the basis of an aspect of the assigning of the divided blocks to the first zone or the second zone by the block assign means;
first transforming means which transforms the boundary by connecting the two selected first points and a point which is optionally selected from the selected second point and the determined third point;
first cell selecting means which selects a first cell which belongs to the first zone and is next to a cell which belongs to the second zone;
second cell selecting means which selects a cell which belongs to the first zone and is next to the first cell, further selecting a cell which belongs to the first zone and is next to the selected cell, and repeating the selection of a cell;
and
second transforming means which transforms the transformed boundary by changing cells having a predetermined location relationship to the selected cells to cells which belong to the second zone.
