How to scroll down a scene? SOLVED

I'm making a scene like this one. Soon I'll finish the space and I don't know how to scroll down like a normal page and make other actors appear

Ok but where shall I place my new actors? There's no space left

Increase the height of your scene:
   

Ok I enlarged the height. And now? Widht 10 tiles and Height 50 tiles.

Now you can place more actors.

Can I scroll by swiping or can I place a arrow to scroll?

To scroll by swiping, create a number attribute called "Y" and add this event to the scene:
   

Thank you

Got a problem when I press down it goes down but then when i click on the actors the screen goes up again

I have tested it and I don't have that problem. The issue must be in other part of your code.

Don't know it's the same

I guess you are using in your game some additional code which affects the camera position.

No other codes. Only actors behavior that switch animation upon click

You have not replicated my code correctly.
You must place the "set Y to..." bock outside the "if..." block, not inside.
