Hei Hun, so I'm wanting to know if you can add this to a avatar and they can drop it as a prop or whatever it's called into any world in VR chat and people can play on it.

This game is made in Udonsharp and VRChat does not allow Udon scripts on avatars

This particular prefab is only made for worlds, and won't function on avatars at all.

Unfortunately, I don't there's a poker prefab that exist for avatars... I think I remember seeing one, but I can't find what I saw anymore.
