* Added a platform level chatbox that games can use * Published games do not have this * Newly published projects have it enabled by default, if the game is networked * Check out the Platform page in Project Settings to turn it off * Party chat uses this, you can also switch between party / game chat if eligible using TAB You can use `Sandbox.Platform.Chat.AddText( ... )` to add system text for notifications or other things. This has blocking behaviour built-in, and you can disable the chat in your settings menu. You can listen to chat messages using `IChatEvent.OnChatMessage`, so if you want to filter for stuff like team chat, add commands to your game, you can do that. We have potential plans for first-party commands / chat channels in the future.
