Google Slides: is there a way to start a function when a specific slide is shown

Question

I need to start a Google Apps Script function whenever a specific slide is shown.

For example: function xyz() should be called whenever slide #3 is opened.

Is it possible?

Answer 1

There are triggers available for using via Apps Script, for Google Slides currently available:

• onOpen - when presentation opened in Google Slides editor
• onInstall - when Google Slides addon is installed
• time-driven (clock)

There are currectly no trigger for slide change in presentation mode, but there are related feature request: https://issuetracker.google.com/issues/36760981 you can "star" it.
