questions about complicated platforms

agueis

I have 3 platforms:
I want that when on each is pressed disappear , and when you click on them again appear,
but this rule : when two platforms on the screen may not appear another , there must always be on screen two platforms and one that can not be displayed ,
you can help me ?

Here's a demo I made. I did not include "when you click on them again appear" so you'll need to add that.

Hello tatiang, can you make me another demo?, i have now 2 platforms,one is with color alpha0 and the other with color alpha 1
when the first platform is touched(alpha 0) nothing happens, when the second platform is touched change to alpha 0, and now you can touch the firs platform or the second , but there will be only one platform in the scene the other is hidden, and the platforms must be statics.
I hope you can help me

I'm confused. Are you changing the setup from three platforms to two? I think it would help if you can draw a picture of how the screen should look.

I think I get it now. The basic logic is that if no actors are "active," then either can be touched. If one actor is active, only that actor can be touched. I started to make you a demo but it's not done and I unfortunately can't spend any more time on it. I hope it's helpful, though!
