Select and deselect instances (radio button style)

Hello,

I'm working a while on this (simple?) problem, but I can't find a solution. I'm working on a strategy game and when you click a building it turns in the "move mode". Ok great, but I can't figure out how to deselect an instance when I click another Instance from the same object. There should be only one instance in move mode like radio buttons.

Here is what I've done:

Explaination:

2/3: "mode_move" on/off state

4: Button to create a new building and turn on the "mode_move"

5: Clicking anywhere "mode_move" turns off and set the new building position

6: Clicking anywhere "mode_move" turns off and set the previous building position when overlapping another building

7: Clicking a building turns "mode_move" off for all instances and turns "mode_move" on for the clicked object

I think event 7 does not work, so you can click multible buildings.

Not sure why so complicated. Or use drag&drop or use an boolean together with a position to mouse (every tick).

If you use drag&drop, it does not need to be disabled. Unless the buildings have a state that does not allow them to move. But i dont see that in your events.

Now you have all the drag&drop conditions.

On drag start

___ Here you can set the boolean, if you need it

On drop

___ Here you can unset the boolean

___ Reposition (snap) if need

Thank you, that helped me a lot.

I want that you first need to click once the building before you kann move it, to prevent accidently move a building while scrolling over the map.

I solved it with a group in this way:
