click to move orthogonal on grid game

is there any topic for moving orthogonal on grid with mouse click or touch? ( 4 direction )

Do you have a project that we can see?

Check out rex plugins and documentation -

The how do I FAQ does have implementation of lots of mechanic, amongst which orthogonal movement (also known as Grid movement).

This tutorial also uses the orthogonal using the keyboard. Nevertheless, it is not too difficult to modify it in order to get the mouse work instead.
