Command input method and recording medium

A recording medium in which a simulation game program is stored to be readable by a computer, the game program being configured in such a manner that two or more competitors take turns to designate an action parameter from an action command frame on a window image for having an object selected by the competitor execute an action so as to let the objects thereof compete with each other in a game space defined on a display plane of a display device, the recording medium storing a control program executing the following steps:

• a switching step for changing the assigned turn of competitors to designate an action parameter;
• a judging step for judging whether the competitor has designated a display of the window image;
• a masking step for masking the action command frame of the window image on the display device of the competitor when the last said competitor has not been assigned a turn;
• a first window image display step for displaying the window image including the action command frame and the non-action command frame on the display plane of the display device of the competitor who has been assigned the turn upon receiving an instruction by the assigned competitor to display the window image;
• and
• a second window image display step for displaying the window image including the non-action command frame and excluding the action command frame on the display plane of the display device of the competitor who is not assigned the turn upon receiving an instruction by the non-assigned competitor to display the window image.

A game apparatus comprising:

• a display device displaying a game image;
• an input device which enables input of a designation by a game competitor;
• a controller controlling the display device to display the game image on the display device according to the designation of the game competitor;
• the controller including a switching device for enabling the input device to provide an assigned turn and a non-assigned turn among two or more competitors such that a competitor with an assigned turn provides an input to said input device to effect execution of an action;
• and
• a game image provider for providing the competitor with the assigned turn with a window image having an action command frame and a non-action command frame and providing the competitor with a non-assigned turn with a window image having the non-action command frame and excluding the action command frame.
