About Modal window Back button

[nevix]

Please someone can explain how to create modal window back button.


I can create events to move forward but lets say, how to get back to previos event.

I want like that: lets say I press back button and creatureEvent bring me back to previos choices.

I will try explain more:

Second: (when I press select)

And I press back button. My question is, how to get back to previos event, previos menu?

You need to (re)create the first Modal Window on that button, or just create a new function for each Modal Window page.

You could extend the Modal Window Metatable to have a metamethod to retrieve the previous window when the back button is clicked or you can create a child Metatable which has all the metamethods and properties of the parent, except for its constructor isn't that off limits?
