Set X() and Set Y() blocks not working in Scratch

Question

I have a sprite that want to drag but when I'm done dragging it want it to place it again to its original position. I have the following blocks:

The block is called without issue the first time (green flag). However, when I'm done dragging the sprite and it's called again in preparing shot, it appears the block doesn't get executed.

Any help is appreciated.

Answer 1

You are using the wrong blocks. You are setting variables called "ball x" and "ball y":

You should be using the "set x" and "set y" blocks:

Also, after you set the ball x and ball y, you are resetting the position:

I am not sure if that is intended.

Answer 2

forever
  go to x:[0] y:[0]
  wait until <<not<(x position) = [0]>>and<<not<(y position) = [0]>>and<not<mouse down?>>>>
end

Answer 3

Because after mouseX and mouseY positions are called it instantly calls setInitialPosition so it doesn't move the ball to mouseX and mouseY.
