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

A game device, for allowing development of a game involving an expansion or contraction object region included in a base region expanded or contracted by a player, comprising:

• first cell attribute storage means for storing a cell attribute representing a positional relationship of the expansion or contraction object region corresponding to each cell constituting the base region;
• base region display means for displaying the base region on a game screen based on a cell attribute of each cell constituting the base region stored in the first cell attribute storage means;
• second cell attribute storage means for storing cell attributes representing a relationship of a closed region for expansion or contraction corresponding to each cell constituting the closed region for expansion or contraction;
• expansion or contraction mark display means for displaying an expansion or contraction position mark representing 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 on the game screen;
• position changing means for changing a relative position of the expansion or contraction position mark with respect to the base region in accordance with a command from a player, so as to generate correspondence between each cell constituting the base region and each cell constituting the closed region for expansion or contraction;
• new cell attribute derivation means for deriving new cell attributes for each cell constituting the base region based on cell attributes of each corresponding cell;
• and
• base region re-display means for displaying the base region on the game screen based on the derived new cell attributes.

A region expansion or contraction method for a game, comprising the steps of:

• displaying an expansion or 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 or contraction object region or to be removed from the expansion or 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 or contraction object region in accordance with a command from a player;
• determining expanded or contracted regions, by adding a portion of the closed region for expansion or contraction that does not overlap the expansion or contraction object region to the expansion or contraction object region, or removing a portion of the closed region for expansion or contraction that overlaps the expansion or contraction object region from the expansion or contraction object region, when the closed region for expansion or contraction comes into contact with the expansion or contraction object region;
• and
• displaying the expanded or contracted region on the game screen in place of the expansion or contraction object region.

A region expansion or contraction method, for a game involving an expansion or contraction object region, included in a base region, expanded or contracted by a player, comprising the steps of:

• storing cell attributes representing a positional relationship of the expansion or contraction object region corresponding to each cell constituting the base region;
• displaying the base region on the game screen based on cell attributes for each cell constituting the base region;
• storing cell attributes representing a relationship of a closed region for expansion or contraction corresponding to each cell constituting the closed region for expansion or contraction;
• displaying an expansion or contraction position mark representing 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 on the game screen;
• changing a relative position of the expansion or contraction position mark with respect to the base region in accordance with a command from a player so as to generate correspondence between each cell constituting the base region and each cell constituting the closed region for expansion or contraction;
• deriving new cell attributes for each cell constituting the base region based on cell attributes of each corresponding cell;
• and
• displaying the base region on the game screen based on the derived new cell attributes.

A game program for causing a computer to function as:

• expansion or contraction object region display means for displaying an expansion or 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 or 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 or 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 or contraction object region to the expansion or contraction object region, when the region closed for expansion comes into contact with the expansion or contraction object region;
• and
• expanded region display means for displaying the expanded region on the game screen instead of the expansion or contraction object region.
