Description
This function is used to create "custom events" for use in user-code, that act mostly like normal Roblox events. For example:
local lib = assert(LoadLibrary('RbxUtility'))
local sig = lib.CreateSignal()
--
sig:connect(function(message)
print("Message: "..tostring(message))
end)
--
sig:fire("Hello, World!") --> Makes the event fire, so that all the handlers are called
Note that the LuaSignal class also supports all of the other properties of events, such as wait:
Spawn(function()
local result = sig:wait()
print("Result: "..tostring(result))
end)
sig:fire("Continue Message") --> Makes any waiting code continue, as well as firing connected functions
