Network system, information processing apparatus and information processing program
View Patent ↗A network system includes a plurality of information processing apparatuses. Each information processing apparatus arranges an own character and a partner character within a virtual space, and outputs an image of the virtual space on a monitor when a message is transmitted and received from the information processing apparatus of a chatting partner. Furthermore, an index indicating a direction from the own character to the partner character is generated, and it is determined whether or not the partner character is included in a predetermined range defined within the virtual space, and it is determined whether or not a message is being transmitted or received. When the partner character is out of the predetermined range, and the message is being transmitted or received, the index is output to the monitor.
