How can I make a fake chat system? Because ChatMakeSystemMessage doesn’t work on TextChatService.
You can’t “fake” chat messages due to the new way messages are handled.
I believe changes like this are due to security issues but I’m not Roblox so we will never know. I checked documentation as I found it odd and as far as I can read I don’t see any methods or properties for such. TextChatService | Roblox Creator Documentation
Some solutions is just to use LegacyChatService as you can fork the chat system and make it however you want though this avoids the true solution as using TextChatService.
I’m not the most experienced when using TextChatService so another solution might appear.
