Need Help - Moving Object

I want to make UI Button with conditions

When I click any button the button(grey object)move based on the arrow angles at the same time.

But I don't know where to start, should I use Custom Movement Behavior or else?.

How would you like it to move?

You could probably use bullet behaviour, set its initial state to disabled and enable it on click.

But I'm not sure what kind of movement you are looking for and if it should only go a certain amount.

In the image, there's three object.

I want to move the objects based on the arrow(just like the image above).

instead of using Bullet or another behaviors, can I Not Using them?

I want to minimize the source to make the best performance.
