After seeing @catherinelagoon's post I also having difficulty in quite understand how to replace an object using a button so is it possible to create a button which when pressed it replaces an existing object on the screen to another object in Smartface App Studio?
I tried using the answer provided in the post however I couldn't understand it much due to I'm a beginner in using Smartface App Studio and coding itself.
Thankyou and sorry for any inconvienience
