I’m not using an animation with a multiple-frame setup, each of my objects is an individual sprite.
You could use the family in all events instead of spCard sprite. But I suggest combining your objects into a single sprite with multiple animations.
found a small bug in your project, when I drag a card and drop it somewhere other than the slot, it goes back to its position, but I can’t drag the same card again; it gets stuck.
Strange, it works fine for me.
