How to move objects in required direction?
<p>My required directions are:</p>

<p><img src="http://i.stack.imgur.com/aiQiw.png" alt="enter image description here">
I've seen from droidz activity example and also from rockpaperscissors example about how to move images in different directions either by using hand or when colliding with walls. </p>

<p>Issue1:</p>

<p>Now I want to move four different images in four directions as shown above. And when they touch the wall up, they should disappear and start again from the starting point one after other and again follow the same direction.</p>

<p>Issue2:</p>

<p>When any of these are touched when moving, either it should disappear and shouldn't continue to loop for that image only or it should take to another activity. 
Please help me with these two issues. Thanks in Advance.</p>
