Hello, I made a modcall system, but I still didn’t finish one thing.
So that thing is a global notification, that’s the thing I don’t know how to send mod call notification to every active server!
You could try using a Messaging Service listener to listen for the modcall. When you run the modcall script, just use the PublishAsync() method of Messaging Service and add in a SubscribeAsync() listener to receive the signal. There’s a tutorial on using the Messaging Service here : Messaging Service
Oh, this function is already added?
I didn’t knew. 
This can be achieved using MessageService, the newly implemented service.
--In a server script
local Announcement = game:GetService("ReplicatedStorage").AnnouncementRemote
Announcement.OnServerEvent:connect(function(player,message) --Detecting when player types announcement.
if player.Name == "DRCGaming" then --Check the player's name in case if they were an exploiter
game:GetService("MessagingService"):PublishAsync("Announcement","Hello all!") --Send the message
end
end)
--In another server script (or in the same one)
game:GetService("MessagingService"):SubscribeAsync("Announcement",function(message) --Note "message" is a string, and when creating the text display, make sure to set the text to message and not "message"
--Your message code here
end)
--In a local script
TextBox.FocusLost:connect(function(enter)
if enter then --Checking if the player pressed enter to close the textbox
game:GetService("ReplicatedStorage").AnnouncementRemote:FireServer(Textbox.Text)
end
end)
Hope this helps

I have a problem: Currently MessagingService doesn’t work in Studio.
This is a known limitation of the MessagingService and the only main workaround is to upload the game to Roblox. Since it is a network call, you will want to use a pcall so a call erroring doesn’t halt the game.

Hmmm, thanks for reply. I’ll try this!
Uhhh, i have a problem.
event.OnServerEvent:Connect(function(plr)
game:GetService("MessagingService"):PublishAsync("LiveModcall", "ModcallTicket")
end)
game:GetService("MessagingService"):SubscribeAsync("LiveModcall", function(reason, sender)
for _,v in pairs(game.Players:GetPlayers()) do
if v.IsMod.Value == true then
if v.PlayerGui:FindFirstChild("ModcallNotify") then
local gui = v.PlayerGui:FindFirstChild("ModcallNotify")
gui.Frame.Visible = true
print(reason)
print(sender)
gui.Frame.Reason.Text = reason
gui.Frame.Username.Text = sender.Name
gui.Frame.PlayerImage.Image = image_format1..sender.UserId..image_format2
gui.Frame.UserId.Text = sender.UserId
gui.ModTicket.PopOut:FireClient(v)
end
end
end
end)
EDIT:
–Local script
local plr = game:GetService("Players").LocalPlayer
event_2:FireServer(panel.InputBox.Input.Text, plr)
event.OnServerEvent:Connect(function(plr)
game:GetService("MessagingService"):PublishAsync("LiveModcall", "ModcallTicket")
end)
game:GetService("MessagingService"):SubscribeAsync("LiveModcall", function(reason, sender)
reason = reason["Data"]
for _,v in pairs(game.Players:GetPlayers()) do
if v.IsMod.Value == true then
if v.PlayerGui:FindFirstChild("ModcallNotify") then
local gui = v.PlayerGui:FindFirstChild("ModcallNotify")
gui.Frame.Visible = true
print(reason)
print(sender)
gui.Frame.Reason.Text = reason
gui.Frame.Username.Text = sender.Name
gui.Frame.PlayerImage.Image = image_format1..sender.UserId..image_format2
gui.Frame.UserId.Text = sender.UserId
gui.ModTicket.PopOut:FireClient(v)
end
end
end
end)
Forgot that SubscribeAsync returns a table. Should be good to go now.
“sender” a nil value…
local plr = game:GetService("Players").LocalPlayer
event_2:FireServer(panel.InputBox.Input.Text, plr)
Is there another way to define player?
Player is automatically defined when firing a remote event.
Ohhhh, okay. Let me try running script again!
The sender, is a player who mod called.
event.OnServerEvent:Connect(function(plr)
game:GetService("MessagingService"):PublishAsync("LiveModcall", plr.Name.." ModcallTicket")
end)
game:GetService("MessagingService"):SubscribeAsync("LiveModcall", function(reason)
reason = reason["Data"]
local sender = reason:sub(reason:find(" "),#reason)
for _,v in pairs(game.Players:GetPlayers()) do
if v.IsMod.Value == true then
if v.PlayerGui:FindFirstChild("ModcallNotify") then
local gui = v.PlayerGui:FindFirstChild("ModcallNotify")
gui.Frame.Visible = true
print(reason)
print(sender)
gui.Frame.Reason.Text = reason
gui.Frame.Username.Text = sender.Name
gui.Frame.PlayerImage.Image = image_format1..sender.UserId..image_format2
gui.Frame.UserId.Text = sender.UserId
gui.ModTicket.PopOut:FireClient(v)
end
end
end
end)
See if this works.
What changes you did in this script?
event.OnServerEvent:Connect(function(plr)
game:GetService("MessagingService"):PublishAsync("LiveModcall", plr.Name.." ModcallTicket")
end)
game:GetService("MessagingService"):SubscribeAsync("LiveModcall", function(reason)
reason = reason["Data"]
local sender = reason:sub(reason:find(" "),#reason)
for _,v in pairs(game.Players:GetPlayers()) do
if v.IsMod.Value == true then
if v.PlayerGui:FindFirstChild("ModcallNotify") then
local gui = v.PlayerGui:FindFirstChild("ModcallNotify")
gui.Frame.Visible = true
print(reason)
print(sender)
gui.Frame.Reason.Text = reason
gui.Frame.Username.Text = sender
gui.Frame.PlayerImage.Image = image_format1..game.Players:GetUserIdFromNameAsync(sender)..image_format2
gui.Frame.UserId.Text = game.Players:GetUserIdFromNameAsync(sender)
gui.ModTicket.PopOut:FireClient(v)
end
end
end
end)
You can’t just get someones user id with name.UserId. Sender is also already a string.
I used this new code and, got no errors
