How do I draw rows or columns of objects with the mouse?

Can I draw rows or columns of objects when the mouse button is down?

something like this

I don't want the objects to overlap one on the other but to be close or spaced by a predefined amount.

Is it possible to do it where the mouse cursor is dragged on?

I was thinking something like in Ninja Up

this is how I would do it - with a single tiled background image made to look like multiple objects.

if you need actual separate objects, it gets a little trickier - you have to wait until the touch/mouse has moved enough to create the next object, and decide what happens if the user doesn't draw in a straight line...

If I want it to act like a rubber band, should I apply revolute joints?
