1. An information processing device executing a battle game in which a player character fights a battle against an enemy character, the information processing device comprising:
a storage unit which stores player information, player character information including an attack strength parameter of the player character, and enemy character information including a hit point parameter of the enemy character, the player information setting, to the player, a spending parameter spent every time a battle is fought as well as a number of game media owned that is used to recover the spending parameter;
a normal battle processing unit which changes the hit point parameter of the enemy character based on the attack strength parameter of the player character by executing a normal battle while spending the spending parameter set to the player in response to an operational input from the player, and recovers the spending parameter spent in the normal battle by using the game media owned by the player in response to a recovery operational input from the player;
a calculation unit which calculates the number of the game media used to recover the spending parameter when the normal battle is fought for a plurality of times until the hit point parameter of the enemy character is brought down to a predetermined value or less by the normal battle processing unit; and
a special battle processing unit which uses, in response to a special operational input from the player, the number of the game media calculated by the calculation unit from among the game media owned by the player, and executes a special battle of bringing the hit point parameter of the enemy character down to the predetermined value or less by fighting the normal battle not for a plurality of times but only once.
2. A non-transitory computer-readable storage medium storing a game program which causes a computer to execute a battle game in which a player character fights a battle against an enemy character, the computer executing:
a storage process of storing, in a storage unit, player information, player character information including an attack strength parameter of the player character, and enemy character information including a hit point parameter of the enemy character, the player information setting, to the player, a spending parameter spent every time a battle is fought as well as the number of game media owned that is used to recover the spending parameter;
a normal battle process of changing the hit point parameter of the enemy character based on the attack strength parameter of the player character by executing a normal battle while spending the spending parameter set to the player in response to an operational input from the player, and recovering the spending parameter spent in the normal battle by using the game media owned by the player in response to a recovery operational input from the player;
a calculation process of calculating the number of the game media used to recover the spending parameter when the normal battle is fought for a plurality of times until the hit point parameter of the enemy character is brought down to a predetermined value or less in the normal battle process; and
a special battle process of using, in response to a special operational input from the player, the number of the game media calculated in the calculation process from among the game media owned by the player, and executing a special battle of bringing the hit point parameter of the enemy character down to the predetermined value or less by fighting the normal battle not for a plurality of times but only once.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A process comprising iteratively decoding a communication channel output until a function based on a number of errors corrected between subsequent iterations reaches a stopping value.
