Release 3.7.4 - Persistence!

Summary​

This update adds Persistence to Udon! Persistence allows you to build VRChat worlds that store data between sessions.

This update also fixes a few minor issues around VRCJSON and VRChat Constraints.

Persistence!​

Persistence allows worlds to save high scores, inventories, the player's last position, currency, unlocks, preferences, and much more. When a player leaves a world and returns later, Udon can access their saved data.

Learn all about the new features in our Persistence SDK docs.

Other Fixes​

  • Fixed VRChat Constraints that need to run before Physbones not updating while in edit mode.
  • Fixed VRChat Constraints that have a child Physbone, but also depend on one, not following their sources correctly.
  • Several fixes for VRCJSON:
    • Fixed an issue where braces inside strings can fail to deserialize.
    • Fixed an issue where empty arrays can fail to deserialize if there is whitespace between the opening and closing, such as [ ].
    • JSON which starts with a BOM (Byte Order Mark, \uFEFF) would fail to deserialize. This character will now be ignored if it is at the start of the input.
