TrueSync deltaTime leads to time loss unless it matches application framerate deltatime

jddev · November 2017

If I don't set the true sync delta time to be the same as the application framerate timing errors quickly start appearing.

In TrueSyncManager you have the following:

tsDeltaTime += UnityEngine.Time.deltaTime;

if (tsDeltaTime >= (lockedTimeStep - JitterTimeFactor)) {
tsDeltaTime = 0;

instance.scheduler.UpdateAllCoroutines();
lockstep.Update();
}

By setting tsDeltaTime to zero you're discarding the difference between tsDeltaTime and lockedTimeStep?

Perhaps instead something similar to the following is better (it fixes my issue anyway)?

if (tsDeltaTime >= (lockedTimeStep - JitterTimeFactor)) {
tsDeltaTime -= lockedTimeStep;

instance.scheduler.UpdateAllCoroutines();
lockstep.Update();
}

Hello @jddev, you are right, in the current implementation we have done something similar to what you did, even multiple updates of the simulation can execute in the same Unity's update.
