With the push by ROBLOX for all Experiences to use the TextFilter I have found this code inside the ROBLOX core modules, it is only visible during run time and is defined as a class (
function, so I have ported it to a module which you can use to filter your text using the same method as ROBLOX does for filtering a user’s public message. I have removed a line which indexed the message into an array with a key equaling weather or not the message passed. Additionally, I have added the ability to parse the message into sentences and only censor the sentence that does not pass the text filter.
local module = {}
local RunService=game:GetService("RunService")
local Chat=game:GetService("Chat")
local MAX_FILTER_RETRIES=6
local MAX_FILTER_DURATION=4
local FILTER_BACKOFF_INTERVALS={.3,4,.5,.6}
function module.ApplyRobloxFilter(fromPlayerObj, message) --// USES FFLAG
if (RunService:IsServer() and not RunService:IsStudio()) then
local filterStartTime = tick()
local filterRetries = 0
while true do
local success, message = pcall(function()
return Chat:FilterStringForBroadcast(message, fromPlayerObj)
end)
if success then
return message
else
--return nil
--warn("Error filtering message:", message)
end
filterRetries = filterRetries + 1
if filterRetries > MAX_FILTER_RETRIES or (tick() - filterStartTime) > MAX_FILTER_DURATION then
return nil
end
local backoffInterval = FILTER_BACKOFF_INTERVALS[math.min(#FILTER_BACKOFF_INTERVALS, filterRetries)]
-- backoffWait = backoffInterval +/- (0 -> backoffInterval)
local backoffWait = backoffInterval + ((math.random()*2 - 1) * backoffInterval)
task.wait(backoffWait)
