Is there a way to make a global chat message appear in legacy chat?

Help and Feedback Scripting Support
#1

basically, ive made a donation system for my game, it works well, but i also want the game to send a message to the chat saying if someone had donated.

although, i have no idea how to do that, and i do not use the new chat for my game, and i do not want to change it, so is there a way to do this for legacy chat?

ive tried searching here for anything, but didnt get anything useful.
anything is appreciated

The legacy chat system uses “ChatMakeSystemMessage” to create a system message.

game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage", {
    Text = "TextHere",
    Color = Color3.fromRGB(255, 0, 0),
    Font = Enum.Font.Michroma,
    FontSize = Enum.FontSize.Size24
})

So create a RemoteEvent, and let a server script receive messages from a single server with Messaging Service, whilst broadcasting a message to all the clients via RemoteEvent with the server script:

local connection = MessagingService:SubscribeAsync("Donation", function(message)
	game.ReplicatedStorage.Announce:FireAllClients(message.Data)
end)

-- Example Line for Global Donation
MessagingService:PublishAsync("Donation", "PLAYER has donated 99,999 Robux!")

And let the client catch that event, and display the message in their chat.

game.ReplicatedStorage.Announce.OnServerEvent:Connect(function(Message)
    game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage", {
        Text = Message,
        Color = Color3.fromRGB(100, 255, 100),
        Font = Enum.Font.Michroma,
        FontSize = Enum.FontSize.Size24
    })
)

And there you have it. Global Donations.

thanks, but i have one question, how are you supposed to detect when the player actually purchases the dev product? since if i make it be on button click it would just appear even if the player didnt donate right?

There is the PromptProductPurchaseFinished event of MarketplaceService.
It provides 3 arguments: The UserID of the player who bought something, the ProductID AKA the ID of the dev product, and finally isPurchased for checking if the player actually bought the dev product or not.

So detecting a bought dev product works like so:

game:GetService("MarketplaceService").PromptProductPurchaseFinished:Connect(function(userId: number, productId: number, isPurchased: boolean)
	if not isPurchased then -- If not purchased, then return as we don't need a rejected request.
		return
	end
	
	
end)
