Editor​

  • Selection now has a freehand select that uses brushes to paint

    • Brush shapes are visualized as grey wireframes, and show only affected blocks in yellow
    • Cusor Control / Mouse Mode is now using a common control which is shared across extensions
    • Brush Selection, Masking and Brush Properties is now using a custom control which is shared across extensions

  • Added support for Brush Shape Offsets

  • Added a new settings screen in View \> View Settings to configure certain view related settings (like invisible block visibility and chunk boundaries)

  • Added mouse button event data to the widget state change event so that server scripts can track mouse button events (press, release, drag) and the state of modifier keys (shift, ctrl)

  • Added an optional infoTooltip: TooltipInteractiveContent property to IRootPropertyPane API, displayed as an icon in the drawer header. Interactive tooltips remain active on hover and support links and paragraphs.

  • Added serialize(obj) and deserialize(string) functions. These act like JSON.stringify/JSON.parse but will use custom serializers/deserializers registered with registerSerializationForType

    • CompoundBlockVolume and BlockVolume are able to be serialized and deserialized with these functions

Changed deleted fillColor and outlineColor in CursorProperties so that causes the Cursor colors to return back to the colors of those keys in the currently-selected theme.
