Lockstep and Rollback Simulation
Category: Deterministic Computing · Kind: Runtime
A tick runner advances lockstep or predicted simulation, restores checkpoints, resimulates and confirms progress.
Common use: Build deterministic gameplay driven by normalized inputs.
Includes: DeterministicSimulationRunner, CounterSimulation, NativeCounterSimulation.
Scope: The simulation step is application-supplied. Tick coordination, history, replay and sessions run on the Managed host; Native kernels can execute in Burst.
