Mouse over visible portion of Sprite (stacked sprites)

1

Hello.

I am developing a card game and I wish to detect when the mouse is over the player’s cards.

My question is: how do I detect when the mouse is over the visible part of each card, since they are all partially stacked on top of each other?

I am inclined to follow the logic:

1- if the card is NOT the top-most one, then set it “virtual bounds” as a small rectangle (the visible part of the card).
2- if the card is the top-most one (7-clubs in my example) then the full card-size rectangle is the area to check for mouse over.

Does that makes sense or there is another easier way of doing this?

Thanks.

why not give your actual bounding rectangles a z-component as well, and sort them like you are sorting it for rendering.

you now just order the bounding-rectangles by z and return the first you find a hit.
