I am making a little tile-based game where each tile is a JPanel and I need to know which tile was clicked with the mouse. What I did is have each tile implement the MouseListener Interface, that way I can simply use event.getComponent() to get the correct instance. However since each map in this game can have like 50x50 tiles (2500 tiles) I wonder if this is memory demanding and perhaps I should just use one listener and map the click coordinates to the correct tile on the map.
What do you think?
I think that 2,500 listeners is a trivially small number when you have 2,000,000,000 bytes to fit them into.
There might be other reasons to use only one listener for the whole panel, or other reasons to use one listener per tile, but I don't think that memory usage is really important.
