Nice, thank you, engineers!

Added a new method ( RBXScriptSignal/Once ) which behaves similar to RBXScriptSignal/Connect , but disconnects immediately when a signal occurs to ensure the callback is only invoked once.

[colbert2677 (Dreamseeker)]

Thanks to sleitnick, I’ve been able to use ConnectOnce in my work with his RbxUtil/Signal library which also supports wrapping RBXScriptSignals with the Signal object and therefore simulating the behaviour of what will be RBXScriptSignal:Once. Having it in-engine is great for developers who don’t have deep frameworks or library integration but need that functionality.

Once can replace a lot of cases of using only Wait on the signal which in itself can potentially either hang or produce a memory leak if an unexpected issue arises when waiting on a signal to fire. It can also remove boilerplate of disconnecting an event immediately after the handler is called.

Lots of love for this one.

No longer need to create a variable just to call Disconnect(), amazing update.

This is a legendary change, and will do a lot for my workflow. God bless.
