Game Communication Engine

This verification program is used to test combinations of Pia network topologies and host migration settings.
Before starting network communications, select the desired combination of settings and use matchmaking to connect devices having those same settings.
This demo only uses Internet communications.
This screen is used to select the settings to use for communication. By design, random matchmaking does not match the local device with other devices that use a different preset combination of settings. All stations in a session must use the same relay emulation and session feature presets.
Input | Operation |
---|---|
X Button | Decide on the settings to use, log in to the Internet game server, and proceed to the Login screen. |
Y Button | Enable or disable latency emulation. You can change send and receive latency emulation delay settings while connected. |
Up/down on the +Control Pad | Change the preset combination of settings being used. |
Left/right on the +Control Pad | Change the relay emulation preset. This setting is enabled only when the network topology is RelayMesh . |
L Button + up/down on the +Control Pad | Change the session feature preset. |
START | Exits the program. |
Lists preset combinations of settings that can be selected on the Settings Selection screen.
Note: The preset combination can be changed dynamically while connected to other devices.

Use this screen to log in to the game server. It creates or joins the session configured on the Settings Selection screen.
Input | Operation |
---|---|
X Button | Starts random matchmaking. Joins available sessions as a client; otherwise, creates a new session as the host. The Main screen then appears. |
START | Logs out from the game server, and navigates to the Settings Selection screen. |
This screen handles communications between each station in the session. Stations can join or leave the session at any time. If host migration is enabled on the host, stations can also leave the session by declaring that they are starting manual host migration. The program automatically goes to the Settings Selection screen if communication cannot continue because of an error or another reason.
A simple manual and Rectangular Movement Area are displayed in the upper right of the screen. Status of Joined Stations is displayed on the left. Current Settings and Dynamically Modify Settings are located at the bottom of the screen.
Input | Operation |
---|---|
START | Ends communication and returns to the Login screen. If the local device is acting as the session host, the session ends. All stations in the session return to the Login screen. |
R Button + START | Ends communication and returns to the Login screen. If the station was the session host, it announces a manual host migration, leaves the session, and returns to the Login screen. (Only when host migration is enabled.) |
X Button | Enable or disable sending data via RoundRobin . |
Y Button | Reset the counters used to calculate the packet loss ratio shown in Status of Joined Stations. (Counters represent the number of packets sent and the number of packets lost.) |
A Button | Use ReliableProtocol to send data one time to all stations joined in the session other than the local station. Data is sent to all addressees using STATION_ID_ALL when sending data via SendToAll has been specified. |
B Button | Switch between simple and detailed display of information in Status of Joined Stations. |
L Button + up/down on the +Control Pad | Scroll information shown in Status of Joined Stations. |
+Control Pad | Move the rectangle corresponding to the local device in the Rectangular Movement Area. |
R Button + X Button or Y Button | Enable or disable Dynamically Modify Settings. |
L Button + up/down on the +Control Pad | Move the cursor used to change settings in Dynamically Modify Settings. |
R Button + up/down on the +Control Pad | Increase or decrease the value of the setting indicated by the cursor in Dynamically Modify Settings. |
R Button + A Button | Apply changes to settings made in Dynamically Modify Settings and execute associated operations. (Changes to some settings are not applied without using R+A.) |
A rectangle corresponding to each station is displayed to indicate communication between stations. Each station sends the position coordinates for its corresponding rectangle to the other stations, and displays the rectangles representing the other stations based on the position coordinates it receives. (UnreliableProtocol
is used to send and receive this data.) Because communication status is most readily checked when stations are constantly moving, stations are automatically made to move to the right if no other specific movement is made.
This section displays the status of each station joined in the current session.
