Patent ID: 7607982

Claim:
A game machine having a dummy ball-hitting member to be operated by a player, wherein a game is played based on results of a ball hitting action in which a stationary ball is hit after a preliminary backward movement of the dummy ball-hitting member by the player, said game machine comprising: a display means for displaying images for the game; an operating signal generating means for measuring at least one of a quantity of operation and a speed of operation of the dummy ball-hitting member by the player to generate an operation signal; a control means that operates to display on said display means a first object representing said operating means and a second object representing the stationary ball to be hit by the first object to move the first object on the display means in response to said operation signal from the operating signal generating means, and to move the second object in an imaginary space on the display means; said control means being configured to calculate a distance between the first object and the second object on the basis of said operation signal of at least one of the quantity of operation and the speed of operation of the dummy ball-hitting member to make a determination as to whether or not said preliminary backward movement of the dummy ball-hitting member is equal to or greater than a predetermined distance; said control means being configured to change at least one of color, shape, size and transparency of at least one of the first object and the second object in said displayed images in response to the determination by the control means that said preliminary backward movement of the dummy ball-hitting member is equal to or greater than said predetermined distance; and said control means being further configured to make a judgment about whether the first object has struck the second object only after it is determined that said preliminary backward movement of the dummy ball-hitting member is equal to or greater than said predetermined distance.
