I'm playing around with making a puzzle game, haven't done that much before I run into my first problem.

Basically, I want to create a certain amount of the same object/function. But without hardcoding the different instances.

I think maybe an array is a good idea? and then a for loop to push the objects in?

And then I need to be able to select one of these objects by clicking on it, how would I do that?

How do I know which ball in the array was clicked? A loop again?

I made a jsFiddle example (you need to click the orange ball to select, then you can move it around by clicking the canvas).

This is what I want to do, but with more balls. How would you solve this?

Help appreciated.
