game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage"),{ Text = "Welcome to my game!"; Color = Color3.new(0,1,1); Font = Enum.Font.SourceSans; FontSize = Enum.FontSize.Size24; })
This is the script to make a server message come up in the chat, and it doesn't work.
The only mistake you made was simply putting an extra parenthesis. You simply need to take out the closing parenthesis at the end of line 1, and your code should work. It will look like this:
game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage",{ Text = "Welcome to my game!"; Color = Color3.new(0,1,1); Font = Enum.Font.SourceSans; FontSize = Enum.FontSize.Size24; })
Also, make sure you're using a Localscript, and it's a descendant of the player. That means, either put it in the StarterGui or the StarterPack, then it should work!
Anyways, I hope this helps. If you're still having problems, or have any further questions, please leave a comment below, and I'll see what I can do.
