Step
Global world step event payload.
Emitted after the physics world advances the simulation time. This event is typically used to:
drive UI state derived from the simulation (FPS counters, timers)
synchronize external systems with the simulation clock
Parameters
delta
Simulated time advanced by this step, in seconds.
sub
Number of internal sub-steps performed to reach this advance (engine-defined; commonly used when accumulating variable frame times into fixed timesteps).
step
Monotonically increasing step counter.
