Syntax
UCLASS&40;Transient, Config&61;Engine&41;
class UBasicReplicationGraph : public UReplicationGraph
Remarks
A basic implementation of replication graph. It only supports NetCullDistanceSquared, bAlwaysRelevant, bOnlyRelevantToOwner. These values cannot change per-actor at runtime. This is meant to provide a simple example implementation. More robust implementations will be required for more complex games. ShootGame is another example to check out.
To enable this via ini: [/Script/OnlineSubsystemUtils.IpNetDriver] ReplicationDriverClassName="/Script/ReplicationGraph.BasicReplicationGraph"
Variables
