# C++ API

The CPP delegate "MnhTracerComp→OnHitDetection" is triggered when a hit, passing through the filtering system, is detected on the Tracer.
The commands "StartTracers" and "StartAllTracers" initiate Tracers to begin checking for hits.
Conversely, the commands "StopTracers" and "StopAllTracers" instruct Tracers to cease checking for hits.
