Talking to Twitch ChatĪside from the OBS API functions, the real meat of the script is the code for communicating with Twitch chat itself. Reordering the message list will also reorder how items appear in the OBS hotkey settings. The list of messages is extensible, and will add / remove hotkeys as list items are changed. These work like any other hotkey in the program and are saved with their message in the script settings. ( Note: I wanted the test message button to use the user-selected message in the list, but that property doesn’t appear to be exposed by the API, at least not yet.) Hotkey HookingĮach message added to the message list gets its own custom hotkey that can be modified in the OBS settings window. There are also two buttons on the bottom of the panel for testing authentication and test sending the first message in the list. These settings are stored with the rest of your OBS settings and are reloaded on startup. Messages: the custom list of messages that can be sent.Oauth: the access key required for authentication to Twitch servers.User: the username of the user posting messages.

Channel: the channel on Twitch to post messages in.With the initial release of the script, these configuration options include: The user can fill in these fields to customize the script without having to modify any configuration files. Via the scripts window, the chat script has access to Qt GUI elements in OBS such as text boxes, lists, and buttons. Since my non-embedded C++ still needs some work, I decided to try writing this program as a Python script rather than a C++ plugin. In the words of the developers, scripting allows you to “quickly extend, add features, or automate the program without needing to build a native plugin module.”

The 21.0 update for OBS added support for Python and Lua scripting, using a new scripting console and an extension of the C API. As a tie-in to my DIY Stream Deck, I wrote a Python script for OBS Studio that allows you to send messages to Twitch chat using OBS’s built-in hotkey system.
