- a plurality of game devices 10 are arranged in each store. Each game device 10 is used by a participant, participates in a tank game in which the participant participates, and causes the participant to play the tank game. Other game devices in the store via the LAN 25 10 can communicate with the matching server device 40 and the game device 10 of another store via the LAN 25, the router 20, and the VPN.
- FIG. 2 is a diagram showing an example of an image displayed on the game apparatus 10.
- the game device 10 displays an image indicating the state of the tank game in which the game device 10 is participating. Specifically, a battlefield image BF and a battle status indicator IND indicating the ratio of damage to each team are displayed. This ratio is determined based on the damage of the three teams . Each team's damage includes damage done to the tanks of the participants of that team.
- the state of the tank game is shared by the game devices participating in the tank game, and should be uniquely determined by one device.
- a mode is assumed in which a specific server device determines the state of the tank game.
- the state of the tank game to be performed simultaneously is determined by a specific server device. That is, the load is concentrated on a specific server device. Therefore, this form is not suitable for large-scale game systems in which many tank games are played simultaneously. Therefore, in each embodiment of the present invention, the state of the tank game is determined by one game device 10 participating in the tank game, and the load is distributed. Thereafter, in each tank game, among the game devices participating in the tank game, one game device that determines the state of the tank game is referred to as a “parent node”, and the other two game devices are referred to as child nodes. ". In each embodiment of the present invention, the parent node transmits / receives data to / from only the child node, and the child node mainly transmits / receives data to / from the parent node.

- a process for specifying the position and posture of a tank a process for specifying the position of a shell
- a process for determining whether or not a shell hits an object such as a tank There is a process to identify damage.
- the time from when game data is generated in each child node until the image in which the game data is reflected is displayed as the reflection delay time of the child node.
- the reflection delay time of each child node is slightly longer than the response time between the child node and the parent node.
- “Response time between A and B” is the sum of the signal transmission delay time from A to B, the processing delay time at B, and the signal transmission delay time from B to A. It is.
- the parent node with each child node as the base point The response time between each child node is a geographical factor such as the distance between each child node and the parent node, or a network configuration factor such as the signal transmission speed of the communication path between each child node and the parent node.
- the response time between each child node and the parent node, and thus the reflection delay time of each child node differs depending on which game device 10 is used as the parent node. This will be explained with a specific example.
- FIG. 3 is a diagram for explaining the relationship between parent node assignment and response time.
- the transmission delay time between the first game device 10 (a) and the second game device 10 (/ 3) is 3, and between the third game device 10 ( ⁇ ) and the third game device 10 ( ⁇ ).
- the communication delay time is 4, which is the transmission delay time force between ⁇ and ⁇ .
- the processing delay times for ⁇ , / 3, and ⁇ are all 1.
- ⁇ is a parent node and / 3 and ⁇ are child nodes
- the parent based on ⁇ is
- the response time for the parent node relative to ⁇ is shorter than (19) when ⁇ is the parent node (9), and the reflection delay time for ⁇ is that ⁇ is the parent node. This is shorter when / 3 is the parent node.
- the response time for the parent node based on each child node depends on which of the game devices 10 that participate in the same tank game that is shorter is the parent node. Therefore, it is important which game device 10 participating in the same tank game is the parent node. [0024]
- Matching is a procedure in which any one game device 10 announces participation in a tank game and becomes a temporary parent node, and another game device 10 expresses participation as a temporary child node to this game device 10. Is done. Then, one of the temporary parent node and the temporary child node becomes the parent node, and the remaining becomes the child node, and the tank game is started.
- FIG. 4 is a block diagram showing a configuration of the game apparatus 10.
- the game apparatus 10 includes a processor 11, an input unit 14, a display unit 15, a communication interface 17, a nonvolatile memory 18, and a rewritable memory 19.
- the processor 11 is, for example, one or a plurality of CPUs (Central Processing Units).
- the input unit 14 includes a plurality of operators. When the operator is operated, the input unit 14 accepts the operation and supplies an operation signal corresponding to the operation to the processor 11.

- FIG. 19 is a block diagram showing an overall configuration of a game system 300 according to the third embodiment of the present invention.
- the difference between the game system 300 and the game system 100 is that the system is closed to one store A. Therefore, the game system 300 has only three or more game devices 70 each connected to the LAN of the store A.
- FIG. 20 is a block diagram showing the configuration of the game device 70.
- the game device 70 differs from the game device 10 in that it has a nonvolatile memory 71 in place of the nonvolatile memory 18 and a rewritable memory 72 in place of the rewritable memory 19.
- the nonvolatile memory 71 is, for example, ROM and EEPROM (Electronically Erasable and Programmable ROM), and stores a program 711 and broadcast address data 712.
- the program 711 is executed by the processor 11 to cause the game device 50 to execute various processes (provisional decision processing, temporary parent node response processing, temporary parent node processing, temporary child node processing, parent node processing, child node processing described later) ).
- the processing performed by the processor 11 is performed using the program 711.
- the broadcast address data 712 is data including the communication address of the game device 70 that is the destination of the temporary parent node response request for requesting a response of the temporary parent node response indicating that it is a temporary parent node. Is included.
- the rewritable memory 72 is also used for temporarily storing a communication address of a device that is a transmission source of data received by the processor 11.
- the rewritable memory 72 is, for example, a RAM, and a participant table T5 for storing participant data is secured in the storage area thereof.
- Participant table T5 has three records corresponding to each participant. Each record stores a communication address of the game device 70 of the participant and a flag indicating the type of the game device 70 (parent node / child node).
- the rewritable memory 72 stores a temporary parent node flag 721 indicating whether or not it is waiting for a participation request as a temporary parent node.
- the initial value of the temporary parent node flag 721 is a value (for example, 0) indicating that the temporary parent node flag 721 is not waiting for a participation request as a temporary parent node.
- the rewritable memory 72 is also used for temporary storage of the communication address of the transmission source device of the data received by the processor 11.
- the nonvolatile memory 71 or the rewritable memory 72 stores its own communication address.
- FIG. 21 is a flowchart of the provisional determination process performed by the processor 11 of the game apparatus 70.
- the processor 11 refers to the broadcast address data 712 and transmits a temporary parent node response request to all game devices 70 (SG1).
- the processor 11 determines whether or not the temporary parent node response has been received (SG2). If the determination result is “NO”, the elapsed time from the broadcast transmission of the temporary parent node response request is a predetermined time. (SG3). If the result of this determination is “NO”, the process returns to step SG2.
- step SG2 If the determination result in step SG2 is "YES”, the processor 11 generates a participant table T5 storing its own communication address, while the value of the temporary parent node flag 721 is set as the temporary parent node. Is set to a value indicating that it is waiting (SG4). Then, the provisional determination process ends.
- step SG3 if the determination result in step SG3 is “YES”, the processor 11 generates the participant table T5 storing its own communication address, while the value of the temporary parent node flag 721 is entered as the temporary parent node. Set to a value (eg 1) indicating that the request is awaited (SG5). Then, the provisional determination process ends.
- FIG. 22 is a flowchart of temporary parent node response processing performed by the processor 11 of the game device 70.
- the processor 11 repeats the process (SH1) for determining whether or not the temporary parent node response request is received until the temporary parent node response request is received.
- the processor 11 determines whether or not the value of the temporary parent node flag 721 is a value indicating the temporary parent node (SH2). If the result of this determination is “NO”, the process returns to step SH1. If the determination result in step SH2 is “YES”, the profiler 11 transmits a temporary parent node response to the game device 70 that is the transmission source of the received temporary parent node response request (SH3). Thereafter, the process returns to step SH1.
- FIG. 23 is a flowchart of temporary parent node processing performed by the processor 11 of the game apparatus 70.
- This temporary parent node processing power The difference from the temporary parent node processing of FIG. 8 is that it is not waiting for a participation request with the temporary parent node flag 721 as the temporary parent node instead of the process of sending the registration cancellation notification (SC5).
- This is a point having processing (SJ1) as a value.
- Pseudo child node processing The reason is as shown in FIG.
- the temporary parent node flag 721 of the game device 70 has a value indicating that it is waiting for a participation request as a temporary parent node (temporary determination processing step).
- the temporary parent node response is not transmitted from the game device 70, and the participation request is not transmitted to the game device 70. Therefore, according to the present embodiment, useless transmission of temporary parent node responses and participation requests can be suppressed even in an environment where a plurality of groups can coexist.
- the same effect as that of the game system 100 can be obtained.
- the game device of the parent node identifies the damage of each team.
- each game apparatus identifies the damage of its own team, and the damage data (game data) indicating the damage is stored in the child node. May be transmitted to the game device of the parent node.
- three damage data may be passed from the parent node to the child node, and the damage ratio may be specified in each child node! /, And the damage ratio (tank game)
- the state data indicating this may be passed to each child node.
- the damage data is data that should be passed from the child node via the parent node to other child nodes.
- the damage data is changed from the child node to the other child nodes via the parent node while changing the format. It can be said.
- each response time is measured by one measurement (transmission / reception), but may be performed by a plurality of measurements. In this case, for example, since the average value of a plurality of measurement results can be used as the measurement result, the measurement accuracy is improved.
- the force S may be three, or four or more.
- the number of participants may be variable. It may also be a game other than a tank game.
- the present invention can be applied to any multiplayer participation game.
- the present invention is also applicable to collaborative work other than games. As such collaborative work, the ability to display the chat can be demonstrated.
