CReplicationGraph and containers​

  • Stubs in demo-tek use a CReplicationGraph child to create containers and to control interest rules. It is expected that any node representing a server node has a CReplicationGraph child.
  • Containers are used to group entities and optimize replication. Entities in a container are replicated to clients based on distance to the container and interest rules.
  • Containers are created with CReplicationGraph.CreateContainer(Callable then). The then callback is called when the container is ready to be used.
  • Example usage in Scenes/Stubs/stub.gd:
var container = $Stub/CReplicationGraph.CreateContainer(func():
    # callback called when the network/container is ready
    print("Container is ready!")
)
container.global_position = $Stub.global_position
label.text = container.GetId().substr(0, 4)
container.add_child(label)
  • You can configure metrics and interest rules via the replication graph API exposed on the CReplicationGraph object:
$Stub/CReplicationGraph.SetMetricToGetDistanceToContainer(getDistanceToContainer)
$Stub/CReplicationGraph.SetContainerServerInterestRule(containerServerInterestRule)
$Stub/CReplicationGraph.SetContainerInterestRule(containerInterestRule)
$Stub/CReplicationGraph.SetDebugAssigns(debugAssign)
