Multiplayer Playmode SDK 1.6.2

Official notes

Added

  1. Feature

    Added Drift detection support for Free Running Instances. Drift occurs when an active Free Running instance becomes desynchronized from the current state of the project within the Unity Editor. This typically happens when development actions, such as a code change, or a modification to an active scene, are performed in the Editor while an Instance is running.

  2. Feature

    Added Drift warning UI icons to both Play Mode Status Window and Play Mode Status Popup. These are displayed when a drift is detected and go away after the Free Running instance is restarted.

  3. Feature

    Character limit of 100 for scenario names and 500 for scenario description to prevent performance issues.

Fixed

  1. Fix

    Fixed an issue where the scenario configuration window warning UI does not display correctly when the corresponding build profile is not installed.

  2. Fix

    Fixed an issue where pausing before entering Play mode didn't keep Multiplayer virtual player(s) paused.

  3. Fix

    Fixed UI overlap when Multiplayer Play Mode window is narrow.

  4. Fix

    Fixed an issue where focusing on a Virtual Player does not bring its window to the front.

  5. Fix

    Fixed an issue where the info HelpBox is not responsive when resizing the Multiplayer Play Mode Window.

  6. Fix

    Fixed an issue where toggling the running mode of a Virtual Player fails after cancelling a running Scenario midway.
