<p>When the system simulates changes of a virtual world and behavior of virtual creatures inhabiting it, the unit time of real time corresponding to the unit time necessary for one processing by the system is divided as time grading. Specifically, when the system is booted up, corresponding to the duration from the time the system power source is cut off previously, simulation is performed by setting the time grading in one second, one minutes, one hour, one day, one week, one month, or one year, for one processing by the system. By upon starting-up of the system, introducing such concept of time grading for the time series, simulation is performed at the time grading corresponding to the duration of the period in which the system has been stopped so far, so that prompt simulation is realized.</p> |
