Most notable changes since v0.48.0:

• "Normal" Python output now is also routed to Python System log files
  • This has the following implications:
  • Can now see python errors that aren't caught by the exception handler we have set up in stp code
    • These "uncaught" python errors don't show up in the ICrashed message that gets sent out and informs things like the Unreal error popup, but at least they are no longer silent! The error popup will instead tell you where to look for the log that probably has the error.
  • Use normal python printing instead of logger, if you so choose
    • Won't be synchronized with st logger so the text may interleave
  • Use libraries that rely on typical output printing for output or error handling
• Fix several issues with user release C++ CMake and compile
• "Waiting for remotes to connect/load/sync/init" warning messages now paired with messages when that phase is completed.
• Fix recently introduced bug that broke Python API BeforeSync/BeforeInit

Most notable changes since v0.47.1:

• Fix "Teleportation" glitch in entity propagation /issues/110
  • As it turns out, this was caused by a missing synchronization step where getting param value and param last-modified time simultaneously was important. Fixed now, and should solve a whole class of very intermittent bugs.
• Fix ST_Rigid_Body propagator handling of timescale changes
  • Now, if an update delta time is negative (as would happen if timescale was externally decreased), the propagator does nothing for that time step and lets extrapolation handle the state in between.
• Added Billboarded Visualizations for Text and Images
  • Documentation WIP
• Fix error in FirstTimeSetup.bat with space in Windows username
• Docstring improvements for pybinded functions

  • Fix Color and Emissive georeferencing (horizontal alignment)

Core C++ Code

• Completely rework Compute_Server source directory organization

  • Within /spaceteams, many C++ files are now sorted into folders for their respective namespaces, which mirror the Python namespaces
    • One notable exception is the Params folder for Parameter code

Python API

• Fix Eigen::Quaterniond-using functions such as math.DCM_to_Quat and PhysEffect.setQuaternion to use 4d vectors instead

Launchpad Installer

The Launchpad installer program is now ready to be used by all to download and update Space Teams PRO versions. It is available from the https://spaceteamspro.com/ download page.

Extra Guidance:

• Name the Profile you make for a version you install something like Main instead of a copy of the version name v1.2.3 as it comes up by default.
• Pausing an install and closing the application will not allow for a proper install restart.
• If you get the Launchpad installer application into a state where you cannot do anything, please contact support at support@simdynamx.com to get up-to-date troubleshooting instructions. We will eventually have good documentation for Launchpad on our wiki, but we have held off on that while we were still making significant changes.

Platform Release v0.45.2

This new Space Teams PRO version has been released and is available for download on spaceteamspro.com.

Space Teams PRO releases that start with 0. are all Beta releases, meaning we have relaxed standards for stability, performance, and backwards compatibility as we quickly introduce new features. Please contact us directly (support@SimDynamX.com) if you are interested in using Space Teams in an environment where software stability is critical.

Most notable changes since v0.44.2:

General

• Parameters now have a key string limit of 31 characters long
  • param_key_t now uses a static_string object for better performance and to fix some obscure DLL issues.
• New Visualizer Entity Type for holographic rendering of curves and 3D shapes.
  • Documentation coming soon! For now, you can access these in the Add Entity menu in the sim UI.
• Additional helper functions available for generating sets of points for curve rendering
  • Documentation coming soon
• Entity_Camera removed CaptureOnMovement behavior, which means we save on performance.
• Python API added bindings for UUID class st.UUID
  • Equivalent of C++ spaceteams::uuid::UUID_t
• Python API fixed many docstrings and default-value-views
• Work-in-progress planet altimetry raytracing utilities

Dynamics

• Fixed an issue which caused the SPICE propagator to not set acceleration of moving bodies.
  • Without this fix, the ST_Rigid_Body propagator was appearing to double the gravitational acceleration of bodies by the sun (and other bodies) because it didn't "know" that the resident frame of the entity, such as Earth-Centered Inertial frame, was already accelerating with respect to the sun.
• New setQuaternion() function for PhysEffect for use for RotationOverride effect type.
  • Not yet working in python code! Use .setVector( ) and .magnitude = instead for now

Publish/Subscribe

• The SimGlobals DispatchEvent and AddEventListener functions have been renamed to Publish and Subscribe, with similar functionality.
  • The names of the concepts involved have changed too. A Publish sends a "Message" with a "payload" on a particular topic and entityId. A Subscribe subscribes on the same topic and entityId. When Subscribe is called, a Subscriber Delegate function is passed which runs when the Message is received with the payload as the input.
  • Python code using the st.DispatchEvent, etc naming does not need to be updated immediately to match the new name, but these old named functions are deprecated and should eventually be updated.
  • AddTransientEventListener is now SubscribeOnce
• Publish/Subscribe New Functionality
  • An optional entityId argument is available to make your Publish/Subscribe more specific. If unspecified, the entityId is the SimEntity's entityId. This should be used to make messages on a topic specific to a certain entity in cases where multiple entities in the simulation are doing a similar thing and may otherwise receive each others messages when subscribing.
  • Before this update, the Events (now Messages) executed delegate functions in one of two ways:
    • Immediately, in the same thread as the DispatchEvent call
    • During the Order Executor thread loop, which processes all incoming data to the program, blocking while the delegate function is running
  • After this update, to avoid most issues with deadlocking, all Publishes only enqueue a Message, and all Subscriber delegates are only ran asynchronously in one of two modes:
    • If argument independentThread is true, the delegate is ran in its own thread. This is a suitable default.
    • Else, the delegate is ran in either its own thread or some program-dependent threadpool that has lower overhead. This is a better option if your delegate is expected to be called many times per second, should take less than 10 milliseconds to run, and does NOT wait for other conditions to be met before returning. Without independentThread, there is more risk of a deadlock situation due to the structure of your simulation code.

Request/Response

• New SimGlobals functions Request and Respond are a new programming feature in Space Teams.
  • Use Request / Respond in situations where you want to get data or request an action that you do not have access to in the current System or thread you are programming in. The behavior can be treated somewhat similarly to HTTP requests.
  • Only one Response is expected for a single Request. Any more responses than one are treated as an error. So, don't set up Respond() on the same topic/entity twice, or include code that takes in more data to decide whether to respond.
• A Respond call sets up a delegate function that takes a Request's payload as input and returns a "Response" payload as output. A Request call sends a payload along with a unique request ID to the entire STP sim and waits for the first Response that it receives on the same request ID. When the response is received, the Request returns the response payload.
• Respond is a blocking call, and has a timeout argument
  • timeout defaults to 10 (real-world) seconds
  • The timeout happens if a response isn't received in time, no matter if a responder exists somewhere in the sim.
  • This timeout will end the blocking call and return an invalid object
    • In C++, this is an invalid std::optional value
    • In Python, this is a None object
  • Always check the output of the Request
    • C++:

      auto response = SimGlobals::Request(...);
      if(!response)
      {
          //Do something to handle failure, log an error, or fatal-log and stop the sim.
      }

    • Python:

      response = st.SimGlobals.Request(...)
      if response is None:
          #Do something to handle failure, log an error, or fatal-log and stop the sim.

  • RequestAsync is an alternative function available in C++ where the std::future object is returned for the user to implement their own waiting scheme.
  • RequestAsyncWithDelegate is suitable for situations when you want to wrap some Request/Response code with a delegate function that will be ran with the received response payload to transform it into a more structured form. A good example of this is for CaptureImageAsync, where we have a recv-delegate that rearranges the parameter response into a CapturedImage object which fulfills the future the CaptureImageAsync returns.
• Respond and RequestAsyncWithDelegate also have optional independentThread, with the same behavior as described above.
• Request/Respond also allow setting a more specific entityId to filter which Responders will respond.

CaptureImage

• Making use of Request/Response, we have the CaptureImageAsync and CaptureImageBlocking functions available as an alternative to CaptureImage/OnImageReceived.
• CaptureImageBlocking allows the user to make much more simple usage of the Camera entity type Unreal rendering. Instead of registering an OnImageReceived delegate function, the C++ or Python code will blocking-wait until the image is captured and received before continuing.
  • A timeout argument is required, and should probably be set to at least 1 second if not 10 to handle lag spikes.

Platform Release v0.44.2

This is copy pasted from the SimDynamX internal repository, so most or all of the links here direct to non-public sites.

This new Space Teams PRO version has been released and is available for download on spaceteamspro.com.

Space Teams PRO releases that start with 0. are all Beta releases, meaning we have relaxed standards for stability, performance, and backwards compatibility as we quickly introduce new features. Please contact us directly (support@SimDynamX.com) if you are interested in using Space Teams in an environment where software stability is critical.

Most notable changes since v0.44.1:

• Fully fixed 3D Model Import tool
• Skip role-selection screen for a few simulation-based tools
• Sun disk now scales in size and brightness correctly based on distance
• Fixed Moon no-collisions bug

Key Known Issues

Also look at https://github.com/SimDynamX/SpaceTeamsPRO/issues to see all publicly reported issues and their current status.

• (Greatly reduced impact) Various small GMRAD issues involving cube-side edges SimDynamX/SC_Platform#783
• SimDynamX/SC_Platform#1739 Some jitter in specific situations, probably involving a time synchronization issue
• (Change in progress) Don't yet have a way to set up Systems on Entities in the SpaceCRAFT sim editing utilities; still requires text-editing the sim config for now.
• Planet small-scale surface detail normal map (detail lighting) 90 degrees out of alignment when at the poles
• ST_Rigid_Body Propagator has issues when ResidentFrame is not SSB. Also applies to Propagator system when PropagationFrame mismatches with ResidentFrame #2872
• 3D Model import crashes without a valid error message when attempting to import certain encodings of .glb file such as Draco-compressed models.
  • The fix is known but will take a while.
