Method OnStopRunning
OnStopRunning()
Called when this system stops running because no entities match the system's EntityQuery objects or because you change the system Enabled property to false.
Declaration
[RequiredMember]
protected virtual void OnStopRunning()
Remarks
If the EntityQuery objects defined for a system do not match any existing entities then the system skips updating until a successful match is found. Likewise, if you set Enabled to false, then the system stops running. In both cases, OnStopRunning is called when a running system stops updating; OnStartRunning() is called when it starts updating again.
