Rhythm game program and game system

A rhythm game program for causing a server device connected to a game terminal device that executes a rhythm game by playing a music and displaying a trigger object on a display unit, through a communication network to control a progress of the rhythm game, the program causing the server device to implement:

• an evaluation function of evaluating an operation input, based on a timing of the operation input of an operation unit for the trigger object and an operation timing associated with data used for playing the music;
• and
• an object control function of moving at least one of the trigger object and an operation position such that a distance between the trigger object and the operation position decreases, based on the operation timing corresponding to the trigger object,
• wherein the object control function implements a function of, when the trigger object for which the operation input has been performed satisfies a first condition, moving the trigger object to a predetermined position where the distance increases, and moving at least one of the trigger object and the operation position such that the distance decreases again.

A game system including a game terminal device which executes a rhythm game by playing a music and displaying a trigger object on a display unit, and a server device connected to the game terminal device through a communication network, the game system comprising:

• an evaluation controller configured to evaluate an operation input, based on a timing of the operation input of an operation unit for the trigger object and an operation timing associated with data used for playing the music;
• and
• an object controller configured to move at least one of the trigger object and an operation position such that a distance between the trigger object and the operation position decreases, based on the operation timing corresponding to the trigger object,
• wherein when the trigger object for which the operation input has been performed satisfies a first condition, the object controller moves the trigger object to a predetermined position where the distance increases, and moves at least one of the trigger object and the operation position such that the distance decreases again.
