How do I a ball collides with "anything"

Hello, this is my problem. I hope someone can help me . I add an image for better explaining.

In my game there are too many blocks (platforms) with the collisions enabled (is the floor). I want that my player throw a ball (it is done. If you know another better way for doing, please tell me :S). The ball has the physics behavior:

Now, what I want is that when the ball collides with any platform (1, 2 or 3 in the image) the ball turns inmovable and not fall. There are too much platforms and I don´t wanto to use: When the ball is on collision with 1, set inmovable / When the ball is on collision with 2, set inmovable,... I want something like: When the ball is on collision with "something" set imovable.

It is that possible? haha

thanks so much!

Put all the platforms in a family, then create the condition: when ball collides with (platform family) set ball to inmovable.

Thank you so much makotto, I think I am stupid :S! LOL

Are you using sprites, 9 patches, or tiled backgroundo for the platforms? (Just curious).

I´m using sprites for the platforms. Is there something better? makotto

I worked on a prototype and used a mix of sprites and tiled background. I was just curious.
