Layers, catch Balls?

[gameZero]

Hi,

I want to write a small game.

On the picture you see three green Layers and Balls (4 Balls. One is checkered, because hidden - behind the layer). The Balls show up randomly - visible or hidden.
When I see a little piece, then I can shoot the ball.

One more thing .... The Layers will be pictures (Trees, meadow etc.) with transparency. The balls will also be pictures.

EDIT:
How can i do that, how check that with the Layers (pictures) and balls? I mean, when i touch the screen (mobile device) and when i see a little bit of the ball i tap it and it will be destroyed.

Thanks for any help!

What's your question?

Clearly, the question is "How can I touch my balls while looking at pictures?".

LOL, but nobody have ideas? Is box2d the answer?

Make all those layers and ball act like buttons. Then handle input in order of that layot. Every button consume imput.

Easy way to get those "buttons" are make layers as polygons and balls as circles. Then just use Intersector class to determine intersection between click point and button area.

Hmm... Sorry i forgot... the Balls are Vectors.

You said, that i should made this with buttons. But i can do that. With Vector, i mean the Spritebatcher etc.
