How do I mode several sprites while drag one

I am using the drag and drop behavior in a sprite and I would like to move 3 other sprites at the same time when I drag it. I tried to pin them to the main sprite and also the "every tick" condition to set their positions, but these tries don't work. Is it possible?

Use one or the other, not both.

(In reference to the pin behavior and setting position manually)

set their positions, but these tries don't work

That is probably because you use 'world' coordinates. While you need 'relative' coordinates.

So first you find the X/Y pixels the dragged one moved compared to last tick.

Say dragged one's name = drag

2 instance variables. dx and dy. Their expressions are drag.dx and drag.dy.

2 instance variables. prex and prey. Their expressions are drag.prex and drag.prey.

Every tick

______ set (drag) dx to drag.x - drag.prex <---------- calculate difference

______ set (drag) dy to drag.y - drag.prey

______ set (drag) prex to drag.x <---------- update to use for the next tick

______ set (drag) prey to drag.y

Now, dx and dy hold the distance drag moved compared to the previous tick.

So ..

On dragging

_____ set any object's position to x= object.x + drag.dx ... y= object.y + drag.y

set their positions, but these tries don't work

Thanks 99Instances2Go

Sorry, but this is a little confusing for me.

I have a main Sprite (that I think you named as "drag") with the drag 'n drop behavior so I need to create these 4 variables in this sprite and in the event "on dragging" I will associate all the other objects (or a family) that I need that follow the main sprite. Is it right?

You add the distance that the main sprite moved/tick to the X&Y of the other objects while dragging the mainsprite.

Is dragging

_____ set any object's position to x= object.x + drag.dx ... y= object.y + drag.y

It worked very well. Thank you. 99Instances2Go!
