I am using the code given by Zyxil at http://www.tasharen.com/forum/index.php?topic=14921.msg65089#msg65089

Have changed the code to put start and end position at sourceGO and targetGO, and draw a straight line.
Issue: As you can see in the attachment that in the scene view, line is drawn correctly. But in Game view the scale of the line is off. How can I correct it?
