Methods

IsClient

Boolean

RunService:IsClient()

Returns whether the current script runs in a client context.

Boolean

RunService:IsServer()

Returns whether the current script runs in a server context.

Signal

Fires once per runtime update with the elapsed time since the previous update.

Parameters

• deltaTime: Number — elapsed time in seconds since the previous heartbeat.

Testing Notes

These observations are from Vortex Studio 0.3.4 and may differ in later releases.

IsClient() returned true in a LocalScript and false in a Script. IsServer() returned the inverse. IsStudio() returned true in both contexts.

Heartbeat supports Connect, Once, and Wait. Its observed deltaTime varied between updates, so it should not be treated as a fixed interval.
