Udon mahjong progress: I still don't have a reliable answer to fixing udon's awful networked positional sync for rigidbodies, but I added a few manual buttons and instructions in the world to mostly get things working. I tried various hacks like slowing down the shuffle, or trying to warp the tiles far away to force the network sync to hard-teleport tiles, but nothing has a reliable effect except forcing the tiles to wake up and perturbing them with a small force.

Anyway, testing with myself it the shuffle works about 90% of the time now though, so maybe it's playable. https://github.com/hiinaspace/just-mahjong is updated with the latest in hacks, so you can take a look if interested.

I think at this point it just requires enough testing and tuning of the RigidBody parameters and timing of the shuffle stages to encode the currently manual button presses into a procedure that works reliably enough, like tanki's shuffle button.

Given how awful the sync is with just flat stacked tiles and 1 board, I don't think it's feasible to have stacked tiles, or multiple tables in one map. But feel free to try it yourself.
