Building on attracting top position and dropping elsewhere

Hello,

Please excuse my English, but partly I used the translator and the translation is not always right. In my language there is no support.

It is perhaps trivial, but I can not figure it out. I have three piles of objects and upwards magnet. I need this magnet pick up most senior facility and the arrow keys to move it along with the magnet on the side position where the facility will put on another pile.

Picking up and dropping need to carry one button on the touch screen.

Many thanks in advance for your advice.

You should track where the magnet is and say

if Magnet.X is between Point A and Point B

AND

if Magnet.Y is between Point C and Point D

then

Facility Pin to Magnet (using the Behavior, Pin).

Where Point A, B, C, and D are near the Facility object.

Thank try. I'm trying for three days without success. I write how it went.

Please do gumshoe2029 otherwise it won't popup on my little notification thing.
