PURPOSE: To change the progress of a game by varying the destruction force of a gun (firearms) by storing the number of times of for a player to operate an operating member as a count value and changing attack power corresponding to this count value. CONSTITUTION: When a program is started, first of all, a CPU circuit 7 clears a pumping counter and judges later whether the player performs pumping or not. In this case, pumping, means the sliding operation of a pumping member provided at the gun. Next, it is judged whether hopping is performed more than twice or not and it is judged whether the player turns on a trigger switch (manipulator 2) or not. Continuous y, the XY position (coordinate) of enemy objects 1-N (N is an integer) is detected and it is judged whether an emitted beam hits any one of enemy objects 1-N or not. Afterwards, the number of times of pumping is investigated from a pumping counter and corresponding to this number of times, the degrees of destruction force are made different. |
