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.

1 . A game device, comprising: 
 expansion or contraction object region display means for displaying an expansion/contraction object region, object being an object for region expansion due to region addition or for region contraction due to region removal, on a game screen;    closed region for expansion/contraction display means for displaying a closed region for expansion or contraction to be added to the expansion/contraction object region or to be removed from the expansion/contraction object region, on the game screen;    position changing means for changing a relative position of the closed region for expansion or contraction with respect to the expansion/contraction object region in accordance with a command from a player;    expanded or contracted region determining means for determining expanded or contracted regions, by adding a portion of the closed region for expansion or contraction that does not overlap the expansion/contraction object region to the expansion/contraction object region, or removing a portion of the closed region for expansion or contraction that overlaps the expansion/contraction object region from the expansion/contraction object region when the closed region for expansion or contraction comes into contact with the expansion/contraction object region; and    expansion/contraction region display means for displaying the expanded or contracted region on the game screen instead of the expansion/contraction object region.    
   
   
       2 . The game device of  claim 1 , wherein 
 the expansion/contraction object region display means displays a borderline of the expansion/contraction object region on the game screen,    the closed region for expansion/contraction display means displays a borderline of the closed region for expansion or contraction on the game screen,    the expansion/contraction region determining means links part of each of the borderline of the expansion/contraction object region and the borderline of the closed region for expansion or contraction to determine a borderline of the expansion/contraction region, and    the expansion/contraction region display means displays a determined borderline of the expansion/contraction region on the game screen.    
   
   
       3 - 4 . (canceled)  
   
   
       5 . A region expansion/contraction method for a game, comprising the steps of: 
 displaying an expansion/contraction object region constituting an object for region expansion due to region addition or for region contraction due to region removal;    displaying a closed region for expansion or contraction, to be added to the expansion/contraction object region or to be removed from the expansion/contraction object region, on the game screen, on a game screen;    changing a relative position of the closed region for expansion and contraction with respect to the expansion/contraction object region in accordance with a command from a player;    determining expansion/contraction regions, by adding a portion of the closed region for expansion or contraction that does not overlap the expansion/contraction object region to the expansion/contraction object region, or removing a portion of the closed region for expansion or contraction that overlaps the expansion/contraction object region from the expansion/contraction object region, when the closed region for expansion or contraction comes into contact with the expansion/contraction object region; and    displaying the expanded or contracted region on the game screen in place of the expansion/contraction object region.    
   
   
       6 . (canceled)  
   
   
       7 . An information storage medium having a game program for causing a computer to function as: 
 expansion/contraction object region display means for displaying an expansion/contraction object region being an object for region expansion due to region addition, on a game screen;    closed region for expansion display means for displaying a closed region for expansion, to be added to the expansion/contraction object region on the game screen;    position changing means for changing a relative position of the region closed for expansion with respect to the expansion/contraction object region in accordance with a command from a player;    expanded region determining means for determining expanded regions, by adding a portion of the region closed for expansion that does not overlap the expansion/contraction object region to the expansion/contraction object region, when the region closed for expansion comes into contact with the expansion/contraction object region; and    expanded region display means for displaying the expanded region on the game screen instead of the expansion/contraction object region.    
   
   
       8 . An information storage medium having a game program for causing a computer to function as: 
 expansion/contraction object region display means for displaying an expansion/contraction object region, being an object for contraction due to region removal, on the game screen;    closed region for contraction display means for displaying a closed region for contraction, to be removed from the expansion/contraction object region, on the game screen;    position changing means for changing a relative position of the region closed for contraction with respect to the expansion/contraction object region, in accordance with a command from a player;    contracted region determining means for determining contracted regions, by removing a portion of the region closed for contraction that overlaps the expansion/contraction object region from the expansion/contraction object region, when the region closed for contraction comes into contact with the expansion/contraction object region; and    contracted region display means for displaying the contracted region on the game screen instead of the expansion/contraction object region.
