- Added player joined/left log messages to ChatHostedService.
- Added an EventAbortedException and suppoet to EventBus for handling it as a way to stop delivery for a specific event.
- Added watch/unwatch methods to the Blackboard and BlackboardState to allow more easily watching specific blackboard properties.
- Modified BlackboardState to support a state ID to make it easier to have multiple blackboards in an application.
- Added EntityContainer.isStarted() to be able to determine if a container has already been started or not.
- Added an IterationProcessorThread class and IterationProcessor interface for managing lock-step background processes.
- Modified EntityUpdater to optionally use an IterationProcessorThread to perform network entity updates on a background thread.
- Added some performance monitoring to EntityUpdater to log a warning when an update takes a lot longer than expected.
- Updated GameSystemManager to set the current frame number as a "frame" logging MDC so that certain logging implementations can include it as part of the log message format.
- Added a SystemTiming class that can optionally be given to GameSystemManager to track per-system timings and dump the information as a warning when a frame exceeds a certain threshold.
- Fixed an NPE when stopping an EntityContainer that did not fully start.
- Modified GameSystemManager initalize() and start() methods to cleanup partial init and partial startup+init on failure.
- Modified EntityContainer's element type detection to better handle parameterized extensions of EntityContainer. (Complete with unit tests.)
- Added an EntityContainer.getComponentTypes() protected method so that subclasses can query the component types.
- Increased base guava version to 21 to get java.util.function compatibility.
- Updated MessageState to allow for a configurable max width that will be applied to created Labels. (so they autowrap at max width)
- Added a bunch of trace logging to the Blackboard class.
- Modified GameSystemManager stop() and terminate() to have exception handling so that one bad system does not (necessarily) prevent the next ones from getting stopped/terminated. This could lead to application hangs if later systems could not properly shut down their threads. Subclasses can override the onStopError() or onTerminateError() methods to control the behavior, which by default logs and moves on.
- Added GameLoop.setPriority() for adjusting the priority of the game loop thread.
- Fixed an issue where registering the same system twice using different keys would also cause it to be executed twice.
- Added GameSystemManager.getSystems() for debugging code to be able to iterate over the active systems.
- Upped the Zay-es versions to 1.7.0-SNAPSHOT
- Updated EntityContainer to work with EntityCriteria objects. Possible breaking change: EntityContainer.getComponentTypes() return type has changed.
- Modified CommandConsoleState to be able to provide a VersionedReference for its enabled state.
- Modified MessageState to support scroll back and different font scale.
- Modified MessageState to use a parabolic curve for alpha fade so it fades slower near the beginning and faster towards 0.
- Modified CommandConsoleState to be more extensible with configurable action map and protected methods for enter(), escape().
- Added a ChatMessage class to encapsulate chat message information which will eventually be used to refactor the ChatSessionListener.
- Modified ChatClientService to keep a limited backlog of received messages while no chat listeners are active. The client caller can then decide to play these back as needed.
- Change the target version of the project to Java 8 to match the few Java 8 classes that are used.
- Added @SafeVarargs to EntityContainer to avoid unchecked varargs warnings.
- Added ChatHostedService.add/removeChatSessionListener() so that the server can listen for chat messages.
- Added ChatHostedService.postMessage() so that a server console can post messages to the chat.
- Added some alternate constructors to GameSystemState that allow passing of an existing/custom GameSystemManager.
- Added GameSystemsState.getGameSystemManager() and GameSystemsState.get(class, boolean) methods.
- Added RecurringTaskSystem for executing general tasks once per frame.
- Added JobState/WorkerPool.isBusy() to indicate if there are still pending/running workers.
- Added JobState.getPoolSize() for querying the number of threads in the pool.
- Modified JobState.getQueuedCount()/getActiveCount() to return the live numbers from WorkerPool instead of the (likely delayed) numbers that the versioned objects are tracking.
- Fixed an issue where shutdown workers were spewing InterruptedException stack traces to the logs during shutdown.
- Changed the element ID for MessageState labels to be "console.message.label" instead of "message.label". The latter was too generic in styling and was often catching optionPanel.message.label as well.
- Fixed BulletSystem collision listener iteration to use getArray() instead of creating an iterator every time. (thanks Ali-RS)
- Fixed a bug in MovementState where disabled states would be auto-enabled if the default camera initialization ran.
- Added a more general WorkerPool class to encapsulate the job management of JobState. Modified JobState to delegate to it.
- Added a Blackboard class and auto-registered it with the GameSystemsManager.
- Added a BlackboardState class for convenient access to a blackboard object in client-side code.
- Renamed the JobState.getQueuedCountReference() and getActiveCountReference() to getQueuedCount() and getActiveCount() respectively. The old one was a typo and since this is a newish class, hopefully it doesn't affect too many folks to fix it now.
- Breaking change to the CommandEntry interface where runCommand() now has a boolean return value. Returning true allows the command to keep the console open.
- Fixed DecaySystem to call the "fail on error" version of getSystem() when looking up the entity system.
- Updated SimTime to have a setCurrentTime() method that allows resetting the simulation to a particular time, either because the game is being reloaded or because it's being continued after a pause, etc..
- Refactored SimTime's internals to make time tracking easier and more flexible.
- Updated GameLoop to call setCurrentTime() on its safe sim time instead of update(), ie: the time returned by GameLoop.getStepTime() This avoids a base time discrepancy but leaves a breaking change that tpf will always be 0. (tpf was generally nonsense before.)
- Updated GameLoop to allow waiting for start() to complete. If waiting then if there is an error during startup then it will be wrapped and rethrown from the start(true) method.
- Added SimEvent.simFailed and modified GameSystemsManager to publish this event if either initialize() or start() fails.
- Fixed a bug in MovementState where the provided walk speed wasn't being adopted unless the run state changed.
- Migrated the build to gradle 7.4.2
- Moved distribution to maven central.
- Added a CubeSceneState for quickly adding a fully lit test scene to an application.
- Added a DefaultSceneProcessor which is basically an empty implementation of JME's SceneProcessor interface.
- Fixed DebugHudState to automatically resize its screen layout when the viewport size changes.
- Updated JME version to 3.3. (To get the new AppState ID methods.)
- Added a JobState class and Job interface for running background jobs in a simple and JME-friendly way.
- Added some standard simple chat service classes for networked apps.
- Added CompositeAppState.clearChildren()
- Modified MovementState to handle null movement targets. The state will be automatically enabled/disabled with non-null/null movement targets, respectively.
- Added an initialize and terminate methods to MovementTarget for the MovementState to call when the target is set.
- Added an AbstractMovementTarget class to shield subclasses from future interface changes.
- Fixed a an issue where EntityContainer.stop() wasn't clearing the internal entity set reference causing other issues if operations were performed on the container after stop.
- Refactored GameLoop to allow setting a custom loop sleep strategy.
- Added a NanoLoopSleepStrategy that uses LockSupport.parkNanos() to sleep and may perform better on some OSes.
- Added a standard MovementState with default mappings for mouse, keyboard, and joystick and a default wiring to the standard JME camera. The movement target is configurable.
- Upped the Zay-ES-net version to 1.4.0 to get the entity set filtering bug fix.
- CompositeAppState modified to use SafeArrayList.getArray() in for loops.
- Modified GameLoop's default frame interval constant to be public: GameLoop.FPS_60
- Added a GameSystemsState utility for managing a GameSystemManager in single player games.
- Added a MemoryDebugState utility that displays memory stats using the DebugHudState.
- Upped Lemur and Zay-ES/Zay-ES-Net dependencies to latest versions (1.12.0 and 1.3.1/1.4.0 respectively.)
- Fixed a SimTime initialization problem where the first tpf would be huge.
- Fixed an issue where EntityContainer wouldn't support nested parameterized types.
- Added GameSystemManager.getStepTime()
- Added GameLoop.getStepTime() that is thread-safe with respect to the game loop thread.
- Added SimTime.toSimTime() and SimTime.getFutureTime(duration) to help with conversion of seconds to game time.
- Added a standard es.common.Decay component for tracking the 'life' of an entity.
- Added a standard sim.common.DecaySystem for automatically destroying entities whose Decay time has expired.
- Added GameSystemManager.get(class, failOnMiss) that can optionally throw an exception if the system does not exist.
- Added AbstractGameSystem.getSystem(class, failOnMiss) that can optionally throw an exception if the system does not exist.
- Added a MessageState that can be used to display fading messages popping up from the bottom of the screen.
- Added a basic CommandConsoleState that can be used to allow command entry (can automatically feed the MessageState).
- Modified DebugHudState to allow user-supplied VersionedObjects to be displayed instead of forcing them to be created through the API.
- Added a CameraState to make it easier to independently set camera parameters like FOV, near, and far plane values.
- Modified SimTime to initialize baseTime to current time on the first frame so that game time begins counting from the first frame.
- Fixed an NPE in CompositeAppState.addChild() when called after the outer state is attached but before it was initialized. See PR #5.
- Added SimTime.getUnlockedTime() which will return a SimTime-translated time between frames, ie: not frame locked.
- Set sourceCompatibility to 1.7 and turned on detailed 'unchecked' warnings
- Suppressed 'unchecked' warnings in some methods of EntityContainer, EventBus, and DecaySystem where it is known that the operations are safe or safe-ish, ie: we know we did it for a reason and don't need to be reminded all the time.
- Increased Zay-ES versions to 1.3.0
- Fixed the EventBus addListener()/removeListener() methods to be static like they were supposed to be.
- Added the ability to add/remove global 'dispatch' listeners to the EventBus. This is useful for things like lifecycle logging or other debug/status related operations.
- Fixed the EventBus to properly check superclasses for autowired event listener methods.
- Exposed the DebugHudState's element IDs to make it easier to restyle the debug HUD.
- Flipped the GameLoop's update loop to sleep when idle instead of only after an actual update was run.
- Modified GameLoop to allow configuring the amount of time to sleep when idle-busy-polling for the next update interval.
- Modified GameSystemManager to log its update errors before sending them to the event bus as a fatal error.
- Modified the EventBus to log.debug() any events that are undelivered.
- Modified the build.gradle to replace the JME version with a specific version instead of letting it float. I think alpha4 is generally the minimum accepted 3.1 version at this point. Did the same for all of the floating version references.
- Added some lifecycle trace logging to GameSystemManager.
- Added a DebugHudState.removeDebugValue() for removing previously created debug values from the HUD.
- Fixed the DebugHudState to clear the background of the "screen" container regardless of style settings.
- Fixed a bug where the wrong class was being reported in the exception message for adding event bus listeners.
- Initial public release with maven artifacts
