transform.position assign attempt for 'Player 1 (qa)' is not valid. Input position is { -Infinity, Infinity, Infinity }.

[Preloading]

I downloaded the source code and when jumping i got...

transform.position assign attempt for 'Player 1 (qa)' is not valid. Input position is { -Infinity, Infinity, Infinity }.
UnityEngine.Transform:set_position (UnityEngine.Vector3)
Interpolator:InterpolatePosition (single) (at Assets/Scripts/Interpolator.cs:66)
Interpolator:Update () (at Assets/Scripts/Interpolator.cs:53)

On both i opened the main scene.

This is a known issue with the interpolation logic, but I suppose it's good that someone finally created an issue about it here :P

The errors are a result of the timeToReachTarget being set to 0, which leads to a divide by zero scenario that causes infinity, negative infinity, and/or sometimes NaN to be assigned to the position. I need to look into why exactly the timeToReachTarget calculation returns 0 sometimes, but I'm not entirely sure when I'll be able to get around to that.

In the meantime, you can avoid the errors by using Mathf.Max to force timeToReachTarget to a value greater than 0, but this is just a band-aid "fix" and not a real solution.

Here's a fix that i found works great:

Right when we're assigning time to reach target

...
timeElpased = 0f;
float ticksToReach = (to.Tick - from.Tick);
if (ticksToReach == 0f) ticksToReach = 1f;
timeToReachTarget = ticksToReach * Time.FixedDeltaTime:

I think this also a temporary fix since i couldn't think what was going wrong in here but this will work 99% of the time i think

In our case setting ticksToReach = 0.001f in if statement did better job

Doing debugging, it looks like it freaks out as a client tick update occures, for example 2753 -> 2800, which causes my case to go to 4000 speed

More debugging, it looks to occur when the to.tick equals from.tick. how to fix it i do not know

This decision helped me:
On the client, go to the tab : Edit -> Time -> Fixed TimeStep set the same value as on the server (0.025)

it tells you to make them the same I think
