When worlds collide

[Rick]

IN LE 3, is it possible to have 2 separate worlds simulating their own physics at it's own time? I'm looking at client side prediction and found a newton forum post that talks about using 2 worlds for client side prediction. The idea is that the server sends timestamped snapshots of where it says your client is in the world. On our client we are storing a list of timestamped positions as well. When we get the server snapshot we need to reposition our local controller to the last know server position, and then replay the rest of the simulation from our locally stored list.

 

So the idea is that we'd do this snapping and replaying in the 2nd world that isn't shown to the player where we can catch up the simulation of the rest of our predictions in 1 game cycle, and then use this final position on the controller in our viewable world as it's current position (most likely interpolating between the viewable world position and 2nd world's position to smooth it out).
