Language Book

Hi, So I have a book that becomes an interface when it opens.
I wanted to enter text in this book that obviously changes depending on the language.
I have to create png for each different language, or can I use another system?

You could try the "display object text" action part found under miscellaneous, but .png is probably simpler & you can apply more visual design to an image however you like as opposed to what can be done with displayed text generated by the engine.

I guess try both & see what works/looks best to you.
