| Parameter | Description |
|---|---|
| state | The SystemState backing this system instance |
Called before the first call to OnUpdate and when a system resumes updating after being stopped or disabled.
If the EntityQuery objects defined for a system do not match any existing entities then the system skips updates until a successful match is found. Likewise, if you set SystemState.Enabled to false, then the system stops running. In both cases, ISystemStartStop.OnStopRunning is called when a running system stops updating; OnStartRunning is called when it starts updating again.
