Manually update Physics World and FixedStep catch up (Server Reconciliation)

Hello all,

Suppose there is a Reconciliation World which will be manually updated so entities can playback inputs that were already processed before in the client to catch up with the current input simulation after a server reconciliation message.

Something like...

Code (CSharp):

1. reconciliationEntityManager.CopyEntitiesFrom(EntityManager, entityList.AsArray());
2.  
3. SetReconciliationWorldSystemsEnabled(true);
4.  
5. for (var updateIndex = 0; updateIndex < length; updateIndex++)
6. {
7.      var time = timeBuffer[updateIndex].Value;
8.  
9.      reconciliationWorld.SetTime(time);
10.      reconciliationWorld.Update();
11. }
12.  
13. SetReconciliationWorldSystemsEnabled(false);

This used to work nicely before the new FixedStepSimulationGroup update. A custom fixed step simulation group already existed with the FixedRateUtils though.

The problem now is, sometimes it's updating the fixed step group a lot, depending on the last time it was updated before it is manually updated again...

If I keep sending inputs and reconciliating, should only take few acceptable ms to execute the reconciliation world updates. But if I stop updating for few seconds and try to update again, there is a stall and hundreds of calls to the FixedStep group update.

From what I've seen from the FixedRateManager code, I believe it's happening because

m_LastFixedUpdateTime

is not being overwritten when setting time for the Reconciliation World. However, I didn't find a way to properly do this...

How should I proceed in this case?

Many thanks!!!

=== EDIT ===

Not happening anymore when using the FixedRateSimple in the Reconciliation World.

Code (CSharp):

1. FixedRateUtils.EnableFixedRateSimple(reconciliationWorld.GetExistingSystem<FixedStepSimulationSystemGroup>(), reconciliationWorld.Time.fixedDeltaTime);
