Server device, program, and method

A computer program product embodying computer-readable instructions stored on a non-transitory computer readable medium for causing a computer to execute a process by a processor, the computer comprising:

• a communication interface configured to receive positional information from a plurality of terminal dives with respect to a plurality of users located in a real world, the plurality of users operating the plurality of terminal devices including first and second terminal devices, the plurality of users including first and second users, the first and second users operating the first and second terminal devices, respectively;
• and
• a memory configured to store one or more of a plurality of items and parameter values of the plurality of items in association with user identification information of each of the plurality of users, the plurality of items including first and second items, the user identification information including first and second user identification information for the first and second users, the first and second items corresponding to the first and second users, respectively,
• the computer configured to perform the steps of:
• assigning the first item to the second user identification information of the second user switched from the first user while the processor maintains correspondence between the first item and the first user;
• receive first current location information as the positional information from the second terminal device in the real world;
• receive second current location information as the positional information from the second terminal device in the real world after a predetermined period of time passes from the reception of the first current location information;
• obtaining a moving distance of the second terminal device in the real world based on the first current location information and the second current location information;
• and
• vary the parameter value of the first item in accordance with the moving distance.

A method for causing a processor in a computer to execute computer-readable instructions stored in a memory, the method comprising executing the computer-readable instructions on the processor the steps of:

• receiving positional information from a plurality of terminal divces with respect to a plurality of users located in a real world, the plurality of users operating the plurality of terminal devices inducing first and second terminal devices, the plurality of users including first and second users, the first and second users operating the first and second terminal devices, respectively;
• storing one or more of a plurality of items and parameter values of the plurality of items in association with user identification information of each of a plurality of users in the memory, the plurality of items including first and second items, the user identification information including first and second user identification information for the first and second users, the first and second items corresponding to the first and second users, respectively;
• assigning the first item to the second user identification information of the second user switched from the first user while the processor maintains correspondence between the first item and the first user;
• receiving first current location information as the positional information from the second terminal device in the real world;
• receiving second current location information as the positional information from the second terminal device in the real world after a predetermined period of time passes from the reception of the first current location information;
• obtaining a moving distance of the second terminal device in the real world based on the first current location information and the second current location information;
• and
• varying the parameter value of the first item in accordance with the moving distance.
