Game device, game region expansion and contraction method, game program and information storage medium

Abstract

A method and apparatus for a game that makes it possible to freely establish a region by expanding or contracting various regions relating to a game with a simple operation. If a closed region for expansion or contraction is moved to a position adjacent to an already established expansion or contraction object region, and an expansion operation performed in a state where a boundary of the closed region for expansion or contraction and a boundary of the object region, the closed region for expansion or contraction is added to the original object region to enlarge the area of the object region. Thus, the boundary displayed overlapping on the object region and the closed region for expansion or contraction are removed, and a single linked boundary is formed on the new object region.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a game device, a region expansion and contraction method for a game, a game program and an information storage medium, and particularly relates to technology for expanding or contracting various regions involved in a game with a simple operation. [0002] Various games have been proposed where if a player sets any region in a game space, game progress related to that region is controlled. For example, in an urban development simulation game, if a player sets a construction region in a game space, buildings etc. are constructed in that region. [0003] In this type of game, when a region is set on a game screen, a method can initially be considered where the width and shape of setting regions are predetermined, and only an arbitrary few of these regions are arranged at arbitrary positions on the game screen (game field). A method of arbitrarily determining the width, shape and position of setting regions using a pointing...

Benefits of technology

[0011] According to the present invention, a base region and an expansion or contraction mark are displayed on the game screen. The base region includes an expansion or contraction object region that is an object of region expansion or region contraction. Also, an expansion or contraction position mark represents a position for adding the closed region for expansion or contraction to the expansion or contraction object region, or a position for removing the closed region for expansion or contraction from the expansion or contraction object region. The base region and the closed region for expansion or contraction are composed of cells, and a relative position of the expansion or contraction position mark with respect to the base region is changed in accordance with a command from a player, so as to generate correspondence between the cells constituting these regions. New cell attributes for each cell constituting the base region are then derived based on cell attributes df each corresponding cell. Cell attributes of each cell constituting the base region represent a relationship between that cell and the expansion or contraction object region. Also, block attributes of each cell constituting the closed region for expansion or contraction represent a relationship between that cell and the closed region for expansion or contraction. That is, new cell attributes are derived based on a relationship b...

Problems solved by technology

However, with the first of these two methods, the setting regions themselves can not be expanded or contracted because the width and shape of the setting regions are determined in advance and each region is handled separately.

This means that if the width, shape and position are arbitrarily determined by a player, there i...
