Frequently Asked Questions - MerlinVR/UdonSharp GitHub Wiki

• Does UdonSharp Support X feature?
• Are prefabs supported fully?
• Can I access the player camera?
• Can I have more than one UdonSharp Udon Behavior on a GameObject?
• I'm starting from scratch and need to use C# tutorials. What common aspects of C# don't work in UdonSharp?

---

If Udon supports it, then so does UdonSharp.

Check Class exposure tree

You can use prefabs with Udon and U#, but changes to serialized fields on those prefabs will not propagate to instances of the prefab correctly due to limitations in Unity.

No, you can not access the player's camera. You can, however, get the head position and rotation.

See VRCPlayerApi.GetTrackingData

Vector3 headPos = localPlayer.GetTrackingData(TrackingData.Head).position

Yes.

If you are learning UdonSharp and not familiar with C# already, you may run across some commonly used techniques that don't work in Udon and UdonSharp yet. These include, but are not limited to, the following:

• Enums not already defined by Unity
• Generic classes (Class<T>) and methods
• Inheritance
• Interfaces
• Method overloads
• Properties

The UdonSharp readme lists additional specific C# features that do not work.
