I am trying to get a esp card game to work but I am having difficulties. Can anyone help?

I've never used sprites in DarkDGK. But I remember reading in this forum some time ago a suggestion that in your case would be to make your cards sprites, and create a sprite that's 1x1 and transparent (or not), that takes the position of your mouse pointer. Then once you detect a mouse click, you can see if the pointer sprite is colliding with a card sprite.
