So, I'm making another drag and drop game and I've some issues when the object is overlapping another object in the same spot. I've create some global variables that holds the position X and Y before dragging the item, and an ID to differentiate the objects (because they are only one sprite with different animations inside). I need to make the object return to his original position or change position with the other object without overlapping him (the object is named: Nomes in the screenshot below).

dop2000 something went wrong, the objects and the panel now are "flashing" (They are changing their position to the max and the min point Y I think)

I need some help to make a menu scroll bar for my game.

The problem is that the objects don't follow the bar when I move it, and I didn't find any tutorial to help me out

In the image, the blue dots are the place where the objects will spawn randomly

(it's a mobile drag and drop game)

I need to make some object shuffle between them without desorganize their position (like the second picture)

Thanks dop2000

I've forgot to ask if it is possible to recive the right or wrong answer only after putting all the objects in a place, so I can make the score system.

Something like a "confirm" button that show your result after placing the objects

I need some help to make a drag and drop game where you need to put some objects in a shelf, each one of them has a specific place. If you put one in a wrong spot, you don't recive any points.

I have no ideia how to make this "checking" if the object is in a wrong spot
