signal:Fire("second")

型

RealSignal

Signal object returned by Signal.new.

Connect (callback: (...any) -> ()) -> RealSignalConnection Adds a callback that runs when Fire is called.Once (callback: (...any) -> ()) -> RealSignalConnection Adds a callback that is disconnected before its first callback invocation.Wait () -> ...any Yields until Fire resumes the waiter with the fired values.Fire (...values: any) -> () Runs connected callbacks and resumes waiters with the provided values.

RealSignalConnection

Connection object returned by RealSignal.Connect and RealSignal.Once.

Disconnect () -> () Disconnects the connection.
