Class FixedTimestep<T extends Time>

java.lang.Object

dev.engine.core.module.FixedTimestep<T>

Type Parameters:

T - the update context type passed to modules

All Implemented Interfaces:

UpdateStrategy<T>

public class FixedTimestep<T extends Time>
extends Object
implements UpdateStrategy<T>

Accumulator-based fixed timestep UpdateStrategy.

Accumulates elapsed time and fires a fixed number of update steps per tick, each step using a constant delta-time value derived from the target frequency. Excess accumulated time beyond the cap is discarded to prevent a spiral of death.
