Abstract

In a game device (200), a storage unit (201) stores a position of a player character, a position of an enemy character, and candidate positions for new enemy character appearance. A measuring unit (202) measures an elapsed time from the start of the game. The calculating unit (203) calculates a reference distance for determining a position where the new enemy character is to be produced based on the elapsed time measured by the measuring unit (202). The reference distance monotonically increases with respect to the elapsed time measured by the measuring unit (202). When a new enemy character is to be produced in the game, an appearance setting unit (204) selects from among the candidates stored in the storage unit (201) the candidate having a distance to the player character that is closest to the reference distance, and sets the selected position as the appearance position of the new enemy character.

Claims

1. A game device that executes a game wherein a player character configured to move based on player instructions and an enemy character exist within a virtual space, comprising:

a storage unit (201) which stores a position of the player character, a position of the enemy character, and candidate positions for enemy character appearance, within the virtual space;

a measuring unit (202) which measures an elapsed time of the game;

a calculating unit (203) which calculates a distance that increases as the measured elapsed time increases; and

an appearance setting unit (204) which stores, as a position of a new enemy character, a candidate position whose distance from the player character is closest to the calculated distance, from among the stored candidate positions for enemy character appearance, to the storage unit (201).

2. The game device according to claim 1, wherein

the appearance setting unit (204) stores the position of the new enemy character in the storage unit (201) in such a manner that the number of positions of the enemy character stored in the storage unit (201) does not exceed a predetermined threshold.

3. The game device according to claim 1, further comprising:

a moving unit (206) which moves the position of the enemy character closer to the position of the player character and updates information stored in the storage unit (201), in a case where the position of the player character is a predetermined distance or more away from the position of the enemy character.

4. The game device according to claim 1, wherein

the appearance setting unit (204), in a case where of the stored candidate positions for enemy character appearance there are a plurality of candidate positions whose distances from the stored player character are same, selects at random a candidate position from those candidates and stores, as the position of the new enemy character, the selected candidate position to the storage unit (201).

5. The game device according to claim 1, wherein

the appearance setting unit (204) selects at random, from among the stored candidate positions for enemy character appearance, a position from among positions included within a predetermined permissible range from a candidate position that locates at a distance that is closest to the calculated distance, and stores the selected position to the storage unit (201) as the position of the new enemy character.

6. The game device according to claim 1, wherein

the appearance setting unit (204), in a case where of the stored candidate positions for enemy character appearance there are a plurality of stored candidate positions that are away by the calculated distance or more, selects at random a candidate position from the plurality of candidates and stores the selected candidate position to the storage unit (201) as the position of the new enemy character.

7. The game device according to claim 4, wherein

the appearance setting unit (204) obtains the movement direction in which the player character moves within a predetermined time period from present, selects at random a position in such a manner that the more in the obtained direction a candidate is, the higher the probability of being selected is, and stores the selected candidate position to the storage unit (201) as the position of the new enemy character.

8. The game device according to claim 5, wherein

the appearance setting unit (204) selects at random a position in such a manner that the closer to the calculated distance a candidate locates at, the higher the probability of being selected is, and stores the selected candidate position to the storage unit (201) as the position of the new enemy character.

9. The game device according to claim 1, further comprising a deleting unit (207) which deletes a position of the enemy character from the storage unit (201) in a case where the player character wins by attacking the enemy character or in a case where a predetermined length of time has elapsed from a moment the appearance setting unit (204) stored the position of the enemy character to the storage unit (201).

10. A game processing method executed on a game device comprising a storage unit (201), which executes a game wherein a player character configured to move based on player instructions and an enemy character exist within a virtual space, wherein:

the storage unit (201) stores a position of the player character, a position of the enemy character, and position candidates for enemy character appearance, within the virtual space; and

the game processing method comprises;

a measuring step of measuring an elapsed time of the game;

a calculating step of calculating a distance that increases as the measured elapsed time increases; and

an appearance setting step of storing, as a position of a new enemy character, a candidate position whose distance from the player character is closest to the calculated distance from among the stored candidate positions for enemy character appearance, to the storage unit (201).

11. A computer-readable information recording medium storing a program for controlling a computer which executes a game wherein a player character configured to move based on player instructions and an enemy character exist within a virtual space, to function as:

a storage unit (201) which stores a position of the player character, a position of the enemy character, and candidate positions for enemy character appearance within the virtual space;

a measuring unit (202) which measures an elapsed time of the game;

a calculating unit (203) which calculates a distance that increases as the measured elapsed time increases; and

an appearance setting unit (204) which stores, as a position of a new enemy character, a candidate position whose distance from the player character is closest to the calculated distance from among the stored position candidates for enemy character appearance, to the storage unit (201).

12. A program for controlling a computer which executes a game wherein a player character configured to move based on player instructions and an enemy character exist within a virtual space, to function as:

a storage unit (201) which stores a position of the player character, a position of the enemy character, and position candidates for enemy character appearance within the virtual space;

a measuring unit (202) which measures an elapsed time of the game;

a calculating unit (203) which calculates a distance that increases as the measured elapsed time increases; and

an appearance setting unit (204) which stores, as a position of a new enemy character, a candidate position whose distance from the player character is closest to the calculated distance from among the stored candidate positions for enemy character appearance, to the storage unit (201).
