Returns the number of supported one-based counter IDs, currently 19. Use PhysicsProfileCounterName for labels and PhysicsProfileCounter after capturing a world for values. Future additions can be appended without renumbering existing IDs. Counter IDs mix current population, latest native work and lifetime peaks, as described below. Population changes without stepping can therefore coexist with timings from the preceding step. Work fields may retain the previous collision/worker-context result when no new work updates that stage. These are not all cumulative counters. World arguments must be live explicit physics worlds; invalid, stale and wrong-kind handles raise a runtime error. Metric indices are one-based and checked before returning values. Captures are rejected while the world is stepping. See also: CapturePhysicsProfile, PhysicsProfileTime, PhysicsProfileCounter, PhysicsNativeBytes, PhysicsWorkerCount. |
