World/Udon Bugs & Feature Requests

We're working on a new character controller for VRChat worlds. It works mostly like VRChat's current character controller, but has a variety of improvements: Players can stand on moving platforms. Going up stairs and slopes is smoother. Players can get pushed around by the colliders. It's better at getting players unstuck from geometry. Udon has greater control over the character controler. ... And more! This feature is still in development and subject to change.

VRChat is working on an improvement to Udon, VRChat's scripting system. Currently, World creators can write code in two different ways: Udon Graph UdonSharp VRChat is introducing a third way: Soba Creators can write Soba scripts in C#, similar to UdonSharp. Soba scripts are compiled to Microsoft's Common Intermediate Language (CIL). This allows Soba to use a variety of features that are not available in the Udon Graph or UdonSharp.

[Steps to reproduce] Lay out many (about 50 or more) MonoBehaviour and VRC_Pickup objects in the scene. Enter the world with 3 or more people. All player pick up and move some objects. Join a new player. The coordinates of some objects are not synced correctly to the new player. [Cause] Maybe, ownership information is not correctly transmitted to new player. In the new player, owner of some objects will appear to be the master. But the owner is actually a different player. So the coordinates by the true owner send to be ignored, the new player will see the object appear to be stationary from its initial position. Also, if an object is picked up by the true owner of that one, SetOwner is not called. So new players will continue to recognize that the master is the owner. [Interim measures] Always the master keep to hold all ownership of objects.
