Write Lua code for the Mudlet application that creates an output window and captures all in-game communications into it
Sure! Here's an example Lua code for Mudlet that creates an output window and captures all in-game communications into it:

```lua
-- Create a new output window with a given name
local outputWindow = createTextWindow("Game Communications", "Consolas", 12, 0, 0, 400, 300)

-- Define a function to capture all game communications and display them in the output window
function captureGameCommunications(event, message)
  if event == "comm" then
    -- Append the incoming message to the output window
    cecho(outputWindow, "<white>" .. message .. "\n")
  end
end

-- Register the function to capture game communications
registerAnonymousEventHandler("comm", "captureGameCommunications")
```

This code creates a new output window with the name "Game Communications" using the createTextWindow function. Then it defines a function called captureGameCommunications that appends all incoming game communications to the output window using the cecho function. Finally, it registers the function to capture all game communications using the registerAnonymousEventHandler function and the event name "comm".

You can customize the code by modifying the output window properties or the way messages are displayed in the output window. Let me know if you have any questions or need further assistance!
