 There will always be some latency for the results to show.
 
 To solve this, there's another BilliardsPredicted demo which uses prediction & reconciliation.

+Notes:
+- Red/White ball Rigidbody CollisionMode needs to be ContinousDynamic to avoid white flying through red sometimes.

 If you are advanced, this demo shows how to use Mirror's prediction features for physics / FPS games.
 
 The demo is work in progress.
