Release Notes 0.3.0

New Known Issues:

  • Enabling Query Based Interest is needed for level streaming support, but this might affect performance in certain scenarios and is currently being investigated.
  • Replicated TimelineComponents are not supported.

For current known issues, please visit this docs page

Features:

  • The default connection protocol is now TCP.
  • Query Based Interest is now supported as an opt-in feature.
  • Level streaming is now supported. You must enable Query Based Interest checkbox in the Runtime Settings to use level streaming.
  • The GDK Toolbar now recognises when a local deployment is running, and contextually displays start and stop buttons. - (@DW-Sebastien)
  • Added interface support for Unreal Engine 4.21 UNetConnection. - (@GeorgeR)
  • Unreliable RPCs are now implemented using events instead of commands. This resolves associated performance issues.
  • The delete dynamic entities setting now works when used in conjunction with multiple processes.
  • You can now determine the type of a SpatialOS worker from within the game instance.
  • Entity IDs are now reserved in batches instead of individually. This accelerates the creation of SpatialOS entities.
  • You can now serialize and deserialize component data defined in external schema (schema that is not-generated by the Unreal GDK). You can use this to send and receive data, and edit snapshots.
  • Improved logging during RPCs.

Bug fixes:

  • The GDK now automatically compiles all dirty blueprints before generating schema.
  • Attempting to load a class which is not present in the schema database now causes the game to quit instead of crashing the entire editor.
  • Actor::ReplicateSubobjects is now called in the replication flow. This means that Subobjects are now replicated correctly.
  • Schema generation is no longer fatally halted when blueprints fail to compile.
  • AActor::TornOff is now called when a TearOff event is received. This is in-line with the native implementation.
  • References to objects within streaming levels, that are resolved before the level has streamed in, no longer cause defective behavior on the client.
  • Attempting to replicate a NonSpatial actor no longer causes a crash.
  • The SpatialOS Launcher now launches the correct game client, even when UnrealCEFSubProcess.exe is present in the assembly.
  • Duplicate startup-actors are no longer created when a server-worker reconnects to a deployment.
  • BeginPlay is no-longer called authoritatively when a server-worker reconnects to a deployment.
  • Fast Array Serialization now operates correctly in conjunction with GameplayAbilitySystem.
  • Reference parameters for RPCs are now correctly supported.
  • Clients now load the map specified by the global state manager, rather than loading the GameDefaultMap before querying the global state manager.
  • Automatically generated launch configurations for deployments with a prime numbers of server-workers are now generated with the correct number of rows and columns.
  • Generating schema for a level blueprint no longer deletes schema that has been generated for other levels.
  • Deleting recently created actors no longer causes crashes.
  • Having multiple EventGraphs no longer causes incorrect RPCs to be called.
  • TimerManager, which is used by SpatialOS networking, is no longer subject to time dilation in the World instance.
  • Clients no longer crash after being assigned multiple players.
  • GetWorkerFlag can now be called from C++ classes.
  • Pathless mapname arguments are now supported by the GDK commandlet.
  • When NotifyBeginPlay is called, BeginPlay is no longer called on actors before their Role is correctly set.
  • Deployments containing multiple server-workers no longer fails to initialize properly when launched through PIE with the use single process option unchecked.
