Signal

Functions for interacting with Roblox signals (events) and their connections. These allow you to inspect, fire, replicate, and control event connections.

getconnections

Returns a table of connection objects for the given signal.

getconnections(signal: RBXScriptSignal) -> {Connection}

Parameter	Type	Description
signal	RBXScriptSignal	The signal to get connections from

Connection Object

Member	Type	Description
Function	function	The connected callback function
Thread	thread	The thread of the connection
Fire(...)	method	Fires this specific connection
Defer(...)	method	Deferred fire of this connection
Disconnect()	method	Disconnects this connection
Disable()	method	Disables this connection
Enable()	method	Enables this connection
Enabled	boolean	Whether the connection is enabled

Example

local connections = getconnections(game.Players.LocalPlayer.Chatted)
for _, conn in pairs(connections) do
    print("Connection function:", conn.Function)
    print("Enabled:", conn.Enabled)
end

firesignal

Fires all Lua connections on a signal with the provided arguments. Does not fire CoreScript connections.

Aliases: fireconnection

firesignal(signal: RBXScriptSignal, ...: any) -> void

Parameter	Type	Description
signal	RBXScriptSignal	The signal to fire
...	any	Arguments to pass to the connections

Example

-- Fire the Chatted event as if the player said "hello"
firesignal(game.Players.LocalPlayer.Chatted, "hello")

replicatesignal

Fires a signal on the server. The signal must be replicable (check with canreplicatesignal).

replicatesignal(signal: RBXScriptSignal, ...: any) -> void

Parameter	Type	Description
signal	RBXScriptSignal	The signal to replicate
...	any	Arguments to pass

WARNING

Not all signals can be replicated. Use canreplicatesignal() to check before calling.

Example

local signal = workspace.Part.Touched
if canreplicatesignal(signal) then
    replicatesignal(signal, workspace.Part)
end

canreplicatesignal

Returns true if the signal can be replicated to the server.

Aliases: issignalreplicate, issignalreplicateable

canreplicatesignal(signal: RBXScriptSignal) -> boolean

Example

local signal = workspace.Part.Touched
print(canreplicatesignal(signal)) --> true/false

getreplicatesignalarguments

Returns a table describing the argument types expected by a replicable signal.

getreplicatesignalarguments(signal: RBXScriptSignal) -> table

Example

local args = getreplicatesignalarguments(workspace.Part.Touched)
for i, argType in pairs(args) do
    print(i, argType)
end

enableconnection

Enables a previously disabled connection.

Aliases: enablesignal

enableconnection(connection: Connection) -> void

Example

local connections = getconnections(game.Players.LocalPlayer.Chatted)
for _, conn in pairs(connections) do
    enableconnection(conn)
end

disableconnection

Disables a connection without disconnecting it. The connection can be re-enabled later.

Aliases: disablesignal

disableconnection(connection: Connection) -> void

Example

-- Disable all connections on an event temporarily
local connections = getconnections(game.Players.LocalPlayer.Chatted)
for _, conn in pairs(connections) do
    disableconnection(conn)
end

task.wait(5)

-- Re-enable them
for _, conn in pairs(connections) do
    enableconnection(conn)
end
