Program product and system

A system for controlling progress of a video game, the video game proceeding in a first three-dimensional virtual space, a first virtual camera being arranged in the first three-dimensional virtual space, the system comprising:

• a communication network;
• a server;
• and
• a user terminal connected to the server via the communication network,
• wherein the server is configured to generate first output information based on information obtained by the first virtual camera,
• wherein the server is configured to generate second output information regarding a selection object, the selection object indicating a target object, the selection object being configured to be selected, the target object being a target of an action when the video game proceeds,
• wherein the server is configured to generate arrangement information regarding arrangement of the selection object indicating a hidden object based on a position of the first virtual camera and a position of the hidden object, the hidden object being the target object existing within an angle of view of the virtual camera and not displayed on an output device of the user terminal,
• wherein the server is configured to transmit output information for outputting a game image based on the first output information, the second output information, and the arrangement information, the game image containing the selection object,
• wherein the user terminal is configured to output the game image to the output device based on the output information, and
• wherein the selection object indicates the position of the hidden object and is generated in the game image by superimposing a second layer image on a first layer image, the first layer image being generated based on the first output information obtained by photographing the first three-dimensional virtual space by the first virtual camera, the second layer image being generated based on the second output information and the arrangement information obtained by photographing a second three-dimensional virtual space by a second virtual camera.

A non-transitory computer-readable medium including a program product for causing a server and a user terminal to control progress of a video game, the video game proceeding in a first three-dimensional virtual space, a first virtual camera being arranged in the first three-dimensional virtual space,

• wherein the program product, when executed, causes the server to:
• generate first output information based on information obtained by the first virtual camera;
• generate second output information regarding a selection object, the selection object indicating a target object, the selection object being configured to be selected, the target object being a target of an action when the video game proceeds;
• generate arrangement information regarding arrangement of the selection object indicating a hidden object based on a position of the first virtual camera and a position of the hidden object, the hidden object being the target object existing within an angle of view of the first virtual camera and not displayed on a display screen of an output device of the user terminal;
• and
• transmit, to the user terminal, information for causing the output device to output a game image based on the first output information, the second output information, and the arrangement information, the game image containing the selection object,
• wherein the program product, when executed, causes the user terminal to:
• receive, from the server, information for outputting the game image on the display screen of the output device of the user terminal, and
• wherein the selection object indicates the position of the hidden object and is generated in the game image by superimposing a second layer image on a first layer image, the first layer image being generated based on the first output information obtained by photographing the first three-dimensional virtual space by the first virtual camera, the second layer image being generated based on the second output information and the arrangement information obtained by photographing a second three-dimensional virtual space by a second virtual camera.
