Game system, game process method, game device, and storage medium having game program stored thereon

A game process method to be carried out in a game system for executing a game control process based on an attitude of a controller device in response to a predetermined game operation made on the controller device, comprising:

• accepting, as a first input, the predetermined game operation performed before the game control process;
• setting, as a tentative reference attitude, the attitude of the controller device when the first input was made;
• further accepting, as one or more additional inputs, the predetermined game operation performed after the first input in a state where the attitude of the controller device is within a predetermined range defined by the tentative reference attitude;
• determining, in response to a predetermined number of said one or more additional inputs, a reference attitude using at least one of the tentative reference attitude and attitudes of the controller device when the predetermined number of said one or more additional inputs were made;
• and
• executing, using a computer processor, the game control process based on the attitude of the controller device and the reference attitude.

A game device for executing a game control process based on an attitude of a controller device in response to a predetermined game operation made on the controller device, comprising:

• a computer system, comprising a computer processor, the computer system being configured at least to:
• accept, as a first input, the predetermined game operation performed before the game control process;
• set, as a tentative reference attitude, the attitude of the controller device when the first input was made;
• further accept, as one or more additional inputs, the predetermined game operation performed after the first input in a state where the attitude of the controller device is within a predetermined range defined by the tentative reference attitude;
• determine, in response to a predetermined number of said one or more additional inputs, a reference attitude using at least one of the tentative reference attitude and attitudes of the controller device when the predetermined number of said one or more additional inputs were made;
• and
• execute the game control process based on the attitude of the controller device and the reference attitude.

A non-transitory computer-readable storage medium storing a game program to be executed by a computer of a game device for executing a game control process based on an attitude of a controller device in response to a predetermined game operation made on the controller device, the game program causing the computer to provide execution comprising:

• accepting, as a first input, the predetermined game operation performed before the game control process;
• setting, as a tentative reference attitude, the attitude of the controller device when the first input was made;
• further accepting, as one or more additional inputs, the predetermined game operation performed after the first input in a state where the attitude of the controller device is within a predetermined range defined by the tentative reference attitude;
• determining, in response to a predetermined number of said one or more additional inputs, a reference attitude using at least one of the tentative reference attitude and attitudes of the controller device when the predetermined number of said one or more additional inputs were made;
• and
• executing the game control process based on the attitude of the controller device and the reference attitude.
