Replace variable: $obsSceneItemVisible[sceneName, itemName] #3416
Description
Describe the solution you'd like
I would like to give Firebot the ability to check in real time if a given scene item is visible on a given scene in OBS. I have implemented, for my own use, $obsSceneItemVisible[sceneName, itemName] which does what you would expect based on the wording - it returns true or false.
Additional context
I've written this code for my own use and would be happy to submit it as a proper PR to Firebot if "Dev Approved." (I couldn't get at enough of the integration to add this via a custom script without completely reimplementing the websocket stuff.)
