Can you do a function call for a function in a different...

external event?

I’m hoping to see if I can run jumping stuff with multiple enemies through the same function, and I currently have their respective AI stuff in different external events

External events are like copied in the scene’s events before building the game (for preview for example). So, you’ll be able to run a function that is in an external event.
But, you can have multiple functions with the same name (or GDevelop will not be able to decide which one to call).

In this case, I’m sure there is an other way around that just by using standard events.
