Abstract: A server device executes one battle by spending the spending parameter in response to a player's operational input, and recovers the spending parameter by using a recovery item owned by the player. The server device calculates the total number of recovery items used to recover the spending parameter when one battle is fought for a plurality of times while repeating spending and recovering the spending parameter in response to operational inputs from the player until a hit point parameter of the enemy character is brought to less than or equal to a value. In response to one special operational input from the player, the server device determines whether the number of recovery items owned by the player is greater than or equal to the total number of recovery items calculated. When the determination is affirmative, the total number of recovery items calculated is automatically used from among the recovery items.

Abstract: A material piece scooping device, which extracts a material piece from a surface of an object to be scooped by cutting electric discharges between an electric discharge electrode and the object to be scooped, includes a rotation drive section 40, an arm portion 30 driven by the rotation drive section to rotate around a rotational axis X, an electrode holder 20 supported by the arm portion, and an electric discharge electrode 10 detachably mounted on the electrode holder. A sliding section for sliding the arm portion in a direction perpendicular to the rotational axis and an arm length adjusting section for adjusting a length of the arm portion from the rotational axis thereof are provided, so as to adjust a trajectory of the electric discharge electrode as the arm portion rotates. The material piece can be scooped from the object along a line of the trajectory gnawing into the object.
