# Room Simulators

Simulators per room can be enabled in the dashboard for the project. The simulator used is matched according to the [simulator slug](https://docs.coherence.io/0.8/simulators/simulator-slugs) in the RuntimeSettings scriptable object file. This is set automatically when you upload a simulator.

For each new room, a simulator will be created with the command line parameters described in the [Simulators](https://docs.coherence.io/0.8/api-reference/simulation-server#command-line-parameters-in-the-cloud) section. The simulator is shutdown automatically when the room is closed.
