Signals

Subscribes to the signal and returns a connection object with :Disconnect(), :Disable(), :Enable() and a .Connected flag.

workspace.ChildAdded:Connect(function(child)
    print(child.Name)
end)

Returns the live connection objects subscribed to a signal, including disabled ones.

for _, conn in ipairs(getconnections(workspace.ChildAdded)) do
    conn:Disable()
end

Subscribes for a single fire.

workspace.ChildAdded:Once(function(child)
    print("first child:", child.Name)
end)

Yields until the signal fires and returns the fired arguments.

local child = workspace.ChildAdded:Wait()
print(child.Name)

Fires the signal manually, useful for BindableEvent-style patterns. firesignal(signal, ...) is the equivalent global helper.

local event = Instance.new("BindableEvent")
event.Event:Connect(function(value)
    print(value)
end)
event.Event:Fire("hello")
