How do you make the ChatWindow's text bold by script?

[milanomaster]

I tried both

chatService.ChatWindowConfiguration.FontFace.Weight = Enum.FontWeight.Bold

chatService.ChatWindowConfiguration.FontFace.Bold = true

Neither of these change the general messages to be bold. Anyone knows?

You must overwrite the FontFace property of ChatWindowConfiguration itself.

local TextChatService = game:GetService("TextChatService")

local ChatWindowConfiguration = TextChatService.ChatWindowConfiguration

local fontFace = ChatWindowConfiguration.FontFace
fontFace.Bold = true
ChatWindowConfiguration.FontFace = fontFace

If you want more customizability, check out the Font datatype.

Ah, that’s quite an interesting one. Haven’t had much time as of lately, but thanks for the solution!
Had this alternative solution first, but that didn’t work when combining bold and italics.

local chatService = game:GetService("TextChatService")

chatService.ChatWindowConfiguration.FontFace = Font.fromEnum(Enum.Font.SourceSansBold)

---

Now updated it to this:

local chatService = game:GetService("TextChatService")

local updatedFontFace = chatService.ChatWindowConfiguration.FontFace
updatedFontFace = Font.fromEnum(Enum.Font.SourceSans)
updatedFontFace.Bold = true
chatService.ChatWindowConfiguration.FontFace = updatedFontFace

or alternatively:

local chatService = game:GetService("TextChatService")

local updatedFontFace = chatService.ChatWindowConfiguration.FontFace
updatedFontFace.Family = "rbxasset://fonts/families/SourceSansPro.json"
updatedFontFace.Bold = true
chatService.ChatWindowConfiguration.FontFace = updatedFontFace

Works well - thanks again! ^^
