Falling Objects

I'm making a 2D game that involve falling objects (bricks and bombs). The game is about catching falling eggs, but the player needs to watch out for bombs and brick. What should I do?

PS The objects need to fall at random

 

Well, I assume that noone will code your game for you. Start here http://docs.unity3d.com/Manual/ScriptingSection.html and here http://unity3d.com/learn/tutorials/modules/beginner/scripting.

For the random order use Random.Range(1, numberofobjects);

 

That sounds pretty straightforward. I whipped up a quick example:

It's pretty self explanatory, but you can follow along what I did to get a sense of how to do it yourself.
