This is the code I have so far; I understand what you mean I just can't see a way to implement it as of yet. Hopefully this will allow you to see what needs to be done to implement your idea.

	public void mouseClicked(MouseEvent e) {

		store closestStore = null;

Start by adding a distanceFrom(int x, int y) method to your store class, which will return the distance from a point (x,y)

public float distanceFrom(int x, int y) {}

Your mouseClicked method can then loop all of the stores and check the distance to each store.

Between that and the pseudo-code I posted above, you should be able to get a start with it.

Hi - I just got up and saw these recent posts.
Ezzaral is right (how many times have I said that now?).
If you look way back in my own posts you will find this:

For closest store you could do a variant on isClicked(...) to return how far the x,y coords are from the center of the door of the store. You can then use these in a simple loop to find which Store is closest.

Then in the following post I proposed exactly the same code.
