Hello. This should be simple, but no matter what I do, filtering a string just returns nil, and I don’t know how to fix it. Any help is appreciated. Thank you.
Server Script:
function filterString(player, str)
if typeof(str) == "string" then
local filteredInstance
local filteredString
local success, err = pcall(function()
filteredInstance = game:GetService("TextService"):FilterStringAsync(str, player, Enum.TextFilterContext.PrivateChat)
filteredString = filteredInstance:GetNonChatStringForUserAsync()
end)
if err then
return "error"
end
return filteredString
end
end
game.ReplicatedStorage.GameEvents.Filter.OnServerInvoke = filterString
Client Script:
local filter = game.ReplicatedStorage.GameEvents.Filter
script.Parent.SendButton.MouseButton1Click:Connect(function()
if script.Parent.TextBox.Text then
local text = script.Parent.TextBox.Text
local filtered, changed = filter:InvokeServer(game.Players.LocalPlayer, text)
print(filtered, text)
if changed then
game.ReplicatedStorage.GameEvents.Suggest:FireServer(tostring(filtered))
else
script.Parent.TextBox.Text = "Suggestion Filtered"
wait(2)
script.Parent.TextBox.Text = filtered
end
end
end)
The print line always prints nil, and then the original text, so it’s not an issue with the source text
There’s no absolute need to pass through the LocalPlayer as a parameter, as Remote instances (RemoteEvents & RemoteFunctions) always give you the Player as the first parameter when you receive it within the server side
Also, I don’t believe you’re using the 2nd parameter of FilterStringAsync correctly as it requires a UserID of the Player you’re exactly trying to filter out here & you’re using the Player object as a whole:
I also recommend changing your variables a bit, so that you don’t accidentally pass through the incorrect data to send through & back
-- Client
local filter = game.ReplicatedStorage.GameEvents.Filter
script.Parent.SendButton.MouseButton1Click:Connect(function()
if script.Parent.TextBox.Text then
local text = script.Parent.TextBox.Text
local filtered, changed = filter:InvokeServer(text) -- Just pass the text only
print(filtered, text)
if changed then
game.ReplicatedStorage.GameEvents.Suggest:FireServer(tostring(filtered))
else
script.Parent.TextBox.Text = "Suggestion Filtered"
wait(2)
script.Parent.TextBox.Text = filtered
end
end
end)
-- Server
function filterString(player, str)
if typeof(str) == "string" then
local filteredInstance
local currentString
local success, err = pcall(function()
filteredInstance = game:GetService("TextService"):FilterStringAsync(str, player.UserId, Enum.TextFilterContext.PrivateChat)
currentString = filteredInstance:GetNonChatStringForUserAsync()
end)
if err then
return "error"
end
return currentString, filteredInstance
end
end
game.ReplicatedStorage.GameEvents.Filter.OnServerInvoke = filterString
After researching the API Reference, you supplemented no parameters for this method as well so we’d need to use the same Player.UserId idea that we had before
currentString should return back as a string datatype afterwards, so replace that variable with:
The filtering works, but now the local script doesn’t detect if it was filtered or not.
This is how I’m handling it:
script.Parent.SendButton.MouseButton1Click:Connect(function()
if script.Parent.TextBox.Text then
local text = script.Parent.TextBox.Text
local filtered, changed = filter:InvokeServer(text) -- Just pass the text only
local equal = tostring(filtered) == tostring(text)
print(filtered, text, equal)
if equal then
game.ReplicatedStorage.GameEvents.Suggest:FireServer(tostring(filtered))
else
script.Parent.TextBox.Text = "Suggestion Filtered"
wait(2)
script.Parent.TextBox.Text = filtered
end
end
end)
Equal always prints true, but then the if statement basically doesn’t run. Any idea why this occurring?
It might have something to do with your FireServer method
If equal is printing back out as true as you stated, then we know for sure that our RemoteEvent should fire properly (Include a print within the equal conditional check to make sure), but something within our RemoteEvent doesn’t seem to be working or it could be that we’re passing in a different parameter
Extremely strange though on why it’d print true, if the conditional check won’t allow it (Just to make sure, try confirming that equal == true instead of just checking for equal)
I also noticed that I forgot to return back an additional parameter for the RemoteFunction, I don’t know if it’ll change anything but you can try it again and see if it works
Unfortunately I don’t know much about how HTTPService works, but from what I see happening is that it looks like the one of your 2 methods at the end don’t seem to be working here
I don’t have much knowledge on why the case would be, as all I can suggest is print() and checking what you’re supposed to get as a result from the HTTP request so I’d consider creating another topic relevant to that issue
I’m marking this as a solution because I learned yesterday that the only way to send webhook requests to discord via Roblox is using a proxy, so that’s why it wasn’t working. Thanks for all of your help!
