change background

Hello again, the question is if I can to guide to learn the best way to change the frame or background by pressing a button.

thanks

Depends on how many backgrounds you need. If you only need 2 then you can use an "instance variable" and set the type to "boolean"

Set a key to "toggle" the "boolean".

When "true" set background 1 to "visible" and background 2 to "invisible"

When "false" set background 1 to "invisible" and background 2 to "visible"

ok thanks. I think I need 4 or 5, the question is why.

Use number variable and place all backgrounds in same sprite under separate animation frames (assuming background does not need animating).

Then do something like this:

on button pressed

.. set background to animation frame Variable

.. Add 1 to Variable

.. if Variable > number of backgrounds

... variable = 0

thanks, i go to do.

I�m sorry for my inglish but I am spanish
