I already searched in ROBLOX Wiki but i didn't found anything. I want send a message from a Script to the default ROBLOX Chat, like in Ultimate Driving or Mad Murderer but i don't know how.
To do this, you would use SetCoreGui
.
game.StarterGui:SetCore("ChatMakeSystemMessage", { Text = "[theCJarmy7] this can make it seem like I chatted something!" })
There are three customization items for this, color, font, and font size.
game.StarterGui:SetCore("ChatMakeSystemMessage", { Text = "Hii!!!", Color = Color3.new(0, 1, 1), Font = Enum.Font.Arial, FontSize = Enum.FontSize.Size24, })
