Computer simulation playback method and simulation

摘要

The invented computer simulation playback method includes the steps of recording commands entered during use of a simulation, operating the simulation with the recorded commands and allowing new commands to be entered at any point during the step of operating the simulation with the recorded commands. More specifically, the invented method runs a simulation on a computer system that includes a user input device and a visual display. Images are shown on the display and the person using the simulation enters commands through the user input device. The commands affect the images shown on the visual display and are recorded in the sequence that they were entered. The method then runs the simulation again and automatically enters the recorded commands in the same sequence that they were recorded so that substantially the same images that were produced when the commands were initially entered are displayed again. During that step, new commands can be entered. Once certain new commands are entered, the recorded commands are preempted and the user can use the simulation anew from the point where the new commands were entered.
