Simulation apparatus, recording medium, and simulation method

A non-transient computer-readable recording medium, recording a simulation program for causing a computer to execute a method of calculating a behavior of a device, the method comprising:

• a first behavior calculation step of calculating a behavior of a first target disposed in a virtual space corresponding to a first device equipped with an accessory device, wherein the first target is a counterpart of the first device in the virtual space;
• a second behavior calculation step of calculating a behavior of a second target in the virtual space corresponding to a second device, wherein the second target is a counterpart of the second device in the virtual space;
• and
• a third behavior calculation step of calculating a behavior of a third target disposed in the virtual space corresponding to a third device, wherein the third target is a counterpart of the third device in the virtual space,
• wherein the second device includes the accessory device,
• the behavior of the first target corresponding to the first device equipped with the accessory device is calculated in the first behavior calculation step at a predetermined time step for each time step, and then a behavior of the accessory device mounted on the first device is calculated based on the behavior of the first target calculated in the second behavior calculation step,
• the first behavior calculation step, the second behavior calculation step, and the third behavior calculation step are synchronized based on a virtual time, so that a same collision detection is reproduced in each simulation in a case where simulation is repeatedly executed,
• in response to detecting that a collision of the second target has occurred, the third behavior calculation step outputting a command to control a position of the first target in the virtual space, and the method comprising a step of generating an image visualizing the virtual space in which the respective targets are disposed, and a step of outputting the image to a display.
